Jeppesen vs. Aeroservices Charts

0 Comments

Many people ask, which set of charts is better? Should I use the FAA Aeroservices charts on Foreflight or pay extra for the Jeppesen charts? Since you have to pay for Jeppesen, they are probably better, right?

I am not here to say which one is better as a chart preference is just that, a preference for one over the other or for certain features. After a while, muscle memory and routine take over and you probably wont even notice the difference.

History

In 1934, Elroy Jeppesen began making his own charts and sold them to other pilots. His little company grew into the giant Boeing chart company we know today. Jeppesen charts are used internationally and therefore include information that might otherwise seem common knowledge, like transition altitudes. The key is, you cannot get FAA Aeroservices charts for international destinations. Jeppesen is the only option for outside the US.

National Aerospace Charting Office (NACO), or the new(er) name “Aeroservices” or FAA chart, whatever you decide to call them, are United States government issued charts. In addition to civilian use, Aeroservices charts are used by the military so there will be some terminology that does not apply to civilians. The best part about FAA Aeroservices charts are… they’re free!

If you are in the middle of a transition or trying to decide which charts to use, you have come to the right place. Here are a few key differences.

Obstacle Departure Procedure Chart

  1. Frequencies: FAA Chart provides the AWOS so you have all departure frequencies in once place.
  2. Airport: Jeppesen highlight the airport, which is a nice feature so you can easily see the flow from the airport.
  3. Notes and Remarks: Jeppesen bolds the speed restriction all over the chart so you won’t miss it. All other requirements are in the top right corner. Note the transition altitude 18,000′. Since Jeppesen is used internationally, it is published on the chart since other countries have different transition altitudes. It takes up a chunk of chart real estate, but it’s clear, easy to read, and always in the same place. The FAA charts post all the requirements and restrictions as notes off to the side. Since it’s in the same space as the chart graphic, it’s easy for the eyes to catch while studying the plate.
  4. Take off Minimums: NOT APPLICABLE for PART 91 – however, it’s wise for all pilots to look and abide by them. Jeppesen displays the standard take off minimums table, as well as the rate of climb table, which is nice to have all in one place. The FAA chart gives the non standard information but you need to know/look up the rest in the Digital Terminal Procedures Supplemental document. (Hint: It’s in the Documents section of Foreflight)
  5. Take Off Obstacles: About the same on both charts
  6. Route Description: Similar on both charts, but larger font and clearer description on the FAA chart. When there are different routes from different runways, the FAA chart layout is really helpful.
  7. Graphic Layout: Jeppesen and FAA use the same graphics for all their different charts and plates which makes it easy to read once you are familiar with the respective charts. FAA charts are easy to read and distractions are kept to a minimum. Jeppesen charts make things bold and enlarge pertinent information so you won’t miss it.
  8. Airport altitude: This is only on the Jeppesen chart (the FAA chart doesn’t include it), but it is very helpful for situational awareness. As you brief the arrival altitudes, I think it’s important to have an idea what AGL you are at.

Approach Charts

One thing pilots love about Jeppesen approach charts is the clear set up for an approach brief. The top section is created as a “briefing strip” starting with the frequencies, then navigation frequencies, minimums, airport elevation and the missed approach. It’s very natural and user friendly.

FAA charts have a slightly bigger picture of the approach planview, but the profile view and minimums section can get a bit cluttered. It can feel a little discontinuous when briefing the approach to bounce all over the page. However, some pilots really like the small airport diagram in the corner, which I find really helpful for situational awareness (particularly for students learning circle approaches). Non- standard alternate and takeoff minimums are also clearly noted, but unfortunately we must hunt elsewhere to find them. The Jeppesen alternate minimums and takeoff minimums will both be on the airport diagram

  1. Frequencies: Getting weather and tuning radios is easy on the Jeppesen charts – just follow the briefing strip. The frequency section on the FAA charts is still easy to read, but closer to the center of the page. It’s split up from the nav frequencies and other important briefing information.
    a. FAA charts are created by the government and have military specific information, which are the odd looking frequencies and channels on the chart.
  2. Approach Navigation: On a Jeppesen chart, you will continue to the next line to verify your frequency, course and set minimums (assuming you are straight in on the ILS). On the FAA chart, you will then have to skip to the top of the chart to get the frequency and course, and then scan to the bottom of the page to input your minimums. However, since you could be flying a localizer approach or a circle to land, it’s a good reminder that not everyone using this approach chart will be using the same Decision Altitude (DA). The FAA chart also includes runway distance information so pilots can make determinations of approach speeds and stopping distance if the runway is wet or icy.
  3. Missed Approach – Textual
  4. Approach Lighting
  5. Missed Approach- Graphical: The missed approach information is the same on both charts. The lighting information is key for determining a missed approach and is next to the missed approach text on the FAA chart. It’s found next to the missed approach graphic on the Jeppesen chart. Personally, I find it easier to find and read the lighting information on the Jeppesen chart. Remember, on both charts, the placement of the PAPI on the chart indicates the physical location of the lights (left or right of the runway).
  6. Notes: Both charts have a notes box, but they use them a little differently. Once again, remember that Jeppesen charts are used internationally and include the transition altitudes and altimeter setting info. On both charts, the notes section will be where other critical information will be shared which isn’t really applicable for this airport. On the FAA chart, the tower frequency is starred to note that there are operating hours (you’ll have to check the chart supplement AF/D to find out what those hours are). There is also an L next to the frequency to indicate it is the pilot controlled lighting frequency. You will also find the note about the VGSI and the Approach Glide path next to the profile view on the FAA chart, whereas the Jeppesen chart has that note in the notes section at the top. The FAA chart also has the T and an A in black triangles to note that this airport has non- standard alternate and take off minimums. Again, those are found in separate documents when using FAA charts and on the Airport Diagram when using Jeppesen charts.
  7. Minimum Sector Altitude: Similar on both charts, but in different locations (reminder: ATC vector altitudes may be lower. It is the pilot’s responsibility for safety of flight to maintain safe obstacle clearance, so if you are ever concerned about going below the MSA – just ask ATC).
  8. Planview: Other then differences in size, visuals, and text, the information displayed on both is very similar.
  9. Profile View: Again, the displays look different and pilots will have their preference, but the information is the same.
  10. Minimums: Jeppesen charts not only note the category for each approach with its designated letter, but also displays it in knots. It is recommended that if you increase your approach speed (based on flaps or gusty winds or perhaps a faster speed for a circle to land approach) that you should use the higher category minimums. The reference guide makes that easy to look up. The other benefit of the Jeppesen charts is right the table that contains the time from the final approach fix to the missed approach point for a localizer approach, it also shows the rate of descent with the associated ground speed to maintain a 3 degree glideslope. Now there is no excuse not to set pitch and power! The minimums posted in parenthesis are for the military, but RVR in statute miles is also included.
  11. Airport diagram: Only on the FAA charts, this particular feature is particularly useful for situational awareness. The arrow pointing to the runway shows the direction the approach is arriving from so planning a circle to land is a cinch. There is also a lot of other information that can be gathered from the airport diagram for quick reference or to help a disoriented pilot: lighting, displaced thresholds, closed taxiways, and runway placement and lengths. This is easily one of the best perks of an FAA chart.

Arrival/ Departure Charts: Sewzy 5 Arrival KAUS

The Jeppesen lay out is very attractive and draws the pilots eye in a clear way to all the important information. The colors pop out, so the required altitudes and speeds are easy to read and remember. The chart, which is the proper scale, shows MORAs , easy to find airports (and runway layouts) and is over all easy to follow. However, the texts, while very clearly laid out, are small and difficult to read and pushed to the very edges of the chart. FAA charts are simple and fairly easy to read, but the airports are not as obvious and the flow to the airport requires a good look. The table on the Jeppesen chart is a really nice format, but the text and Notes for arrivals on the FAA chart are easy to find and much easier to read quickly.

  1. Frequency: FAA charts include the approach frequency on the arrival, which is helpful for having radios tuned. During a busy time when the controller changes your frequency, all you have to do is verify the frequency you already set, rather then totally stop what you’re doing to switch it. The Jeppesen charts add the airport elevation next to the ATIS, which really aids situational awareness.
  2. Notes: Jeppesen notes are clearly numbered and tucked away nicely in a box, but the FAA chart notes pop out in the middle of the page and are easy to skim for pertinent information.
  3. Planview: I think Jeppesen is the clear winner here- it is so easy to read, it only takes one glance to know where the primary airport is and how the arrival flows. The chart being at the proper scale offers the pilot important geographical information and over all is a clean look. Notice the small series of arrows after SMRFF on the the Jeppesen chart; those indicate the pilot should expect radar vectors. The FAA charts include those instructions in the text, but I find the visual reference on the chart helpful. The FAA charts are equally clean, with altitude and speed restrictions easy to read even if they don’t jump out. When there are multiple airports that the arrival serves, the airports are clearly marked, though, I think it would be nice to have a little more information surrounding the primary airport for better situational awareness.
  4. MSA: only on the Jeppesen chart
  5. Primary airport: The runway alignment and grey highlight on the Jeppesen chart stands out very clearly, while the FAA airports are a little more obscure.
  6. Arrival route description: The table on the Jeppesen chart is easy to follow but the text is very small and pushed to the bottom. The route description is much easier to find and read on the FAA chart.

Airport Diagram

The Jeppesen Airport Diagram page has it all: frequencies, airport diagram, runway info, take-off minimums, departure procedures and alternate minimums. It’s a one-stop shop. It makes preflight planning easy when its all at your fingertips.

The FAA charts usually require a little more searching for different pieces of airport information. The Airport Diagram itself is just the airport layout. Above, you will see a simple FAA Airport diagram. It’s clean and simple, perfect for a knee board print out.

In the flight planning process, as you look at what approaches you will be using for the airport, you might see an A or T inside a triangle. Those indicate that you will need to look in the Alternate Minimum or Take off minimum documents for more information. The Takeoff Minimums document (see below) is also where you will find any obstacle departure procedures for that airport. Apps like Foreflight help you out by posting the take off minimums under the departure tab. Even though it’s a little more difficult to read, I didn’t crop out the airport information so you can see what it looks like in context.

Dry Motoring a PT6

0 Comments

When it comes to turboprop engines, a hot start is a really bad thing. For you piston drivers out there thinking, “What’s the big deal, you are just starting a hot engine,” then here’s a little education for you.

In a PT6 turboprop engine, there is a very important temperature gauge that a pilot monitors very closely during each and every start. It is called the Inter-Turbine Temperature gauge, or ITT. This temperature is a measurement of the exhaust gases between the compressor turbine and the power turbine (s). In the picture below, the probe is located where the blue and red colors meet.

In a turboprop engine, specifically the Pratt & Whitney PT-6 in all it’s different sizes and variations, there will always be a specific temperature that the pilot will want to keep the ITT below. This article will deal specifically with a Piper Meridian.

A Piper Meridian starts hotter than almost any other PT6 engine because of the way it’s air intake is designed. Unlike other turboprops, the Meridian has a permanently open inertial separator. This means that not all the intake air makes it to the engine during start because some of it goes out the inertial separator opening. So, coming to a Meridian from operating other turboprop engines can lead to a little bit of a surprise on the ITT temperature being higher than what a pilot is used to when starting.

As a rule of thumb, when starting a Meridian, never let a start continue when the ITT hits 875 degrees. Based on the chart below, you are still in the safe zone at 875 and have about a 50 degree buffer before you have to start getting worried.

On cold starts with a good battery or a GPU, 875 is typically not an issue. Most starts when cold are going to be in the high 700s or low 800s. On a cold start, if you are seeing starts in the mid to upper 800s, try starting with a GPU and see if that lowers the start temperature. If it does, then that means your battery is weak and needs to be replaced. Another tell-tale sign of a weak batter is the Ng doesn’t spool up properly (meaning it settles around 12-13%) or takes a really long time to spool up. Also, never start on the battery with less than 24 volts.

When there are multiple flights in one day, the pilot has to take into consideration the warm engine prior to starting. If the ITT, prior to the start sequence, is above 150 degrees, it is time to do some motoring of the engine.

What is motoring? It is simply using the starter to turn the engine, which leads to air being sucked into the engine allowing the engine to cool off prior to start. The theory is, the cooler your engine prior to start, the cooler the ITT peaks at during start.

Here’s the steps on how to dry motor a Piper Meridian:

  • Battery on
  • Strobes on
  • Fuel Pumps and Ignition off
  • Throttle idle
  • Condition Lever feather/cutoff
  • Push the start button
  • Monitor the ITT temperature
  • Reaching 150 degrees, if less than 30 seconds have elapsed:
    • Fuel Pumps on
    • Ignition On
    • Condition Lever run
  • Reaching 150 degrees, if 30 seconds have elapsed:
    • Push Manual/Stop button to stop the start
    • Let starter rest for 30 seconds

The starter has a 30 second limit on the Meridian, followed by a 30 second rest period. You can do the sequence twice, then, after the 3rd start, there is a 30 minute rest period. Typically, if the ITT won’t cool down to 150 after the 3rd time, there is probably something wrong.

The most important thing a pilot can remember is never, ever push the condition lever forward if the ITT is above 150 degrees. You’ll be well on your way to avoiding hot starts that way.

Cirrus Braking Systems: A Hot Topic

0 Comments

You just bought your Cirrus SR22. You do some flying, and soon find yourself with a brake temp sticker that isn’t white anymore. You remember from your transition training that any color other than white is a no go. You now ponder…. I don’t remember getting on the brakes hard, or riding the brakes while taxiing, but sure enough they aren’t white anymore. You now start thinking that all the horrible rumors of Cirrus brakes are true. They overheat so fast!

I would like to share some little-known facts about the Cirrus factory equipped braking system. Following the procedures below can help make the brakes last a little longer. There is also a very popular STC that allows upgraded brakes to be installed on all SR series aircraft. More to come on that.

Notice the Top Yellow sticker is far darker than the Bottom. The Yellow temperature indicator turns at 300 Degrees, while the bottom Blue indicator turns at 330 Degrees. This is an indication to the pilot that if the bottom sticker has turned colors, that the braking system has exceeded 330 degrees and is in need of servicing.

Above is a photograph of an SR22 G1 braking system with turned brake temp stickers. The first things you may notice is that there are in fact two brake temperature stickers. We can only see the bottom blue sticker from the inspection port on the wheel pants. The other is higher on the caliper; in order to see it, the wheel pant must be removed. This isn’t common knowledge because there is no mention of this additional indicator in the POH.

Now you may be asking yourself, what can I do to extend the service life of my factory equipped Cirrus brakes? Here are some tips. First, always taxi at 1000 RPM and use the rudder as much as you can while only tapping the brakes. This is not fool proof, since sometimes, depending on the grade, you will have no choice but to utilize brake tapping to keep the aircraft going straight. Taxiing is not typically where the brakes get overheated, though, but this is still a good practice to follow.

What we tend to see is that the Cleveland brakes are generally overheated on landing. We always recommend to make sure your final approach speed is not excessive, land in the first 1/3 of the runway, and let the aircraft rollout to a smooth stop. What tends to happen is that the aircraft is too fast, and the pilot tries to exit at a certain taxi way, or brakes hard and continues to ride the brakes after landing during taxi. If you do your best to avoid these habits, it will serve you well.

This braking system remained unchanged all the way until the 2016 G5 Cirrus SR series. Starting in 2016, the factory equipped G5 and G6 Cirrus SR series all now come standard with a single piston hydraulic braking system from Beringer. The Cirrus Beringer brakes far exceed the braking power and durability of the old system. The new system is more robust, withstands heat better, and is is very well built. There is also an option for an upgraded dual caliper system to increase durability and stopping power. A braking system STC for the older Cirrus G1 through early G5 models was created to upgrade those airplanes to the better stopping power and cooling of the Cirrus Beringer brakes.

Seen above is a page from a Beringer catalog highlighting the Cirrus SR series STC kits. Your local Cirrus service center will be able to quote prices for the kits. We have over 1000Hrs spent behind Beringer equipped Cirrus aircraft and the difference is quite apparent. The pilot has better control of the aircraft, no spongy pedal, and the confidence to get the plane stopped without possibly overheating the braking system. This, in our opinion, is one of the best upgrades you can do to your Cirrus.
Above is what an STC upgraded braking kit from Beringer looks like, as well as the new temperature indicator for the pre/post flight inspection. Notice the black spot on the left hand picture. These brakes have been overheated.

One other difference for a pilot to note is that once upgraded to the Cirrus Beringer brakes, there is only one temperature indicator and it changes color at a whopping 450 Degrees Fahrenheit! Needless to say, it can handle some heat! The new temperature indicator is now Orange in color and turns grey/black when overheated.

On the left are the original Cirrus factory brakes. On the right is the caliper to the new Beringer brakes for a Cirrus.
Dual Caliper Cirrus Beringer Brakes

The Cirrus Beringer brakes upgrade is quite a step up in the world of slowing down. However, this doesn’t mean that they are completely issue free. There is one little-known problem with Beringer brakes that is not that big of a deal and can be fixed with relative ease.

The rotor on the Beringer braking systems is “free floating,” meaning it is not necessarily “fixed” in position when secured down to the spindle. It is “keyed” into the wheel rim with the male and female side interlocking.

The brakes occasionally will get noisy, causing a “knocking” noise when brakes are applied. This noise is caused by the small metal tabs that tighten up the space between the wheel and the brake rotor. This is so the small tabs wear with use instead of the aluminum rim that they are fixed to. So, if your Beringers are making a knocking noise when brakes applied, this is most likely your culprit.

These gaps above are the “keyed” position where the rotor finds home in the rim. Without these tabs that wear with use, we would be replacing the rim more often than the much cheaper replaceable tabs.

It is highly recommended to upgrade your original Cirrus factory brakes to the new Beringer braking system. You will deal with less maintenance, less chance of a brake overheat, and less confusion on whether or not your brakes are airworthy. For more info, you can check out the Cirrus website for the single or dual caliper Beringer brakes.

Coflyt Ownership App

0 Comments

A new app came out last year that fits a need for many owners. Coflyt, available on the Apple App Store for $14/month for up to two airplanes, helps immensely with staying organized. Those questions of, “When is my oil change due?” or “Has the plane had it’s IFR inspections?” are easily answered by checking the app instead of having to dig through maintenance logs.

Not only does Coflyt help keep track of maintenance, but it also houses squawk lists that owner’s can send to maintenance shops as well as keeping track of Airworthiness Directives. If the pilot remembers at the end of flights to put the amount in, it even shows how much fuel is remaining in the airplane.

For flying clubs and partnerships, it provides easy scheduling without having to share calendars. Payments can also be taken and flights tracked. No more paper flight sheets after flights to track down.

As a pilot, it helps immensely to be organized. For $14 a month ($36/month for partnerships or flying clubs), that’s a small price to pay.

The Anatomy of a Hot Start

2 Comments

Are you one of those pilots who hates fuel stops simply for the fact that the engine doesn’t have time to cool off?  You pump gas into the plane, hit the bathroom, get in the plane and the oil temperature is still up at 160-170 degrees, leading you to have to figure out how to get the plane going again with a hot engine.  For those without proper training, this usually means a lot of jockeying around with the throttle, mixture, and fuel pump to try and get the thing started without flooding it.  After coughing and wheezing several times, the engine finally comes to life, leaving you to only guess what worked and without the knowledge of how to duplicate it.

Hot Start 2

Let’s take a step back for a minute to see what is actually happening with a hot engine.  Once the engine is shut off, the fuel in the lines leading from the tank to the engine is vaporized, meaning there is more air in the fuel lines than liquid fuel.  In the engine block itself, there is still liquid fuel in the injectors, but only enough for the engine to cough then quit if started.

When a normal priming and starting procedure is performed, too much fuel is forced into the cylinders and the engine becomes flooded.  A flooded engine just means that the stoichiometric ratio is way too rich, meaning there is too much fuel and not enough air.  The prime does the trick of getting the fuel vapor out of the fuel lines, but it shoves too much fuel into the cylinders.  Once the engine is flooded, it’s a waiting game to allow air into the engine to get the mixture right.  All Lycoming powered high performance and turbo charged engines are notoriously easy to flood when hot.

So, what’s the solution?  By taking a step back to see what is actually happening, you can attack the problem from the source, which is the fuel lines.  You need to get the vapor out of the fuel lines and get some liquid fuel in there.  The procedure for this varies based on the make and model of engine, but I’m going to use the example of the Continental IO-550-N that is in a Cirrus SR22.  I found this procedure in the Continental Engine Manual and it works every time.

(Pilots of other airplanes, keep reading.  I have sections below for PA46s, Columbias, and Bonanzas as well )

  • Mixture:  Full Lean (this allows fuel in the fuel lines, but prevents it from going past the mixture control into the engine, sending all fuel back to the fuel tank; a small amount of fuel leaks past the mixture control providing prime for the engine)
  • Throttle:  Idle
  • Low Boost Pump:  Run for 30-60 seconds (see note below)  (15 seconds in the Turbo Cirrus)
  • Mixture:  Full Rich
  • Throttle:  Open about 1/4 travel (not 1/4″, that won’t be enough)
  • Boost Pump:  Off, but have your finger on Low Boost
  • Starter:  Crank (engine will turn over a few more times before firing, this is normal)
  • At the first indication of start, turn the Low Boost on, increase the throttle to ensure the engine catches,  then adjust the throttle for 1,000 RPM
    • The engine will fire right about the time you start thinking it isn’t going to work

A few notes regarding engine temperatures:

  • If the oil temperature is above 150 degrees, a hot start will be required.  If oil temp is close to 200 degrees, run low boost for 60 seconds in a non-turbo.  If oil temp is 175, run low boost for 45 seconds in a non-turbo.  If oil temp is 150, run low boost for 30 seconds in a non-turbo.  Use 15 seconds for all temps above 150 in a Cirrus Turbo.
  • If the oil temperature is between 125-150, skip the hot start procedure, don’t prime the engine, leave the boost pump off, and crank the engine, then boost pump on when it starts and slightly increase throttle to make sure the engine catches
  • If the oil temperature is between 100-125, skip the hot start, don’t prime the engine, and perform a normal start with the boost pump on
  • If the oil temperature is below 100, perform a normal prime and start

Piper Malibu (PA46-310P with Continental Engine)

  • Mixture:  Full Lean (this allows fuel in the fuel lines, but prevents it from going past the mixture control into the engine, sending all fuel back to the fuel tank; a small amount of fuel leaks past the mixture control providing prime for the engine)
  • Throttle:  Idle
  • Low Boost Pump:  Run for 15-30 seconds depending on oil temperature…
    • Greater than 150 degrees: 30 seconds
    • Less than 125-150 degrees:  15 seconds
    • Less than 100-125 degrees, no need to run the Low Boost
    • Perform normal cold start below 100 degrees
  • Mixture:  Full Rich
  • Throttle:  Open about 1/4 travel (not 1/4″, that won’t be enough)
  • Boost Pump:  Off, but have your finger on the Primer Button
  • Magnetos:  On
  • Starter:  Crank (engine will turn over a few more times before firing, this is normal)
  • Engine should fire with the Low Boost Pump off, but…
    • If the engine starts to die, simultaneously increase the throttle a little bit and hit the primer button.
    • Only tap the primer button, don’t hold it as you’ll flood the engine if you hold it At the first indication of start, turn the Low Boost on, increase the throttle to ensure the engine catches,  then adjust the throttle for 1,000 RPM

Piper Mirage & Matrix (PA46-350P and PA46-350T with Lycoming Engine)

  • Leave throttle and mixture idle
    • Before you turn the battery on, ensure the mixture is idle cutoff
    • If the mixture is forward and the battery is on, the low boost pump in the fuel tank will start pumping fuel to the engine and quickly flood it
  • Ensure Magneto switches are on
  • Open throttle 1/4 travel (not 1/4″ as this won’t be enough)
  • Crank
  • As soon as the engine begins coughing and wheezing (and this is what it will sound like), push the mixture 3/4 of the way forward
  • Once the engine has a good solid fire, smoothly and swiftly push the mixture all the way forward
  • Reduce throttle
  • Note:  The Emergency Boost Pump can be used as part of the hot start technique, but I usually leave it off.
    • Pro to the Emergency Boost Pump is it can help suck more fuel in and purge vapor during the start
    • Con is that if the engine doesn’t start on the first try, you are flooding your motor

Columbia 400

  • Throttle and Mixture Idle Cutoff
  • Vapor Suppression:  Run for 30-60 seconds.  Reference above temperatures on the non-turbo Cirrus for run times
  • Mixture full forward
  • Throttle 1″ in
  • Prime for 3 seconds, then off
  • Crank
  • Once engine fires, primer might need to be pushed momentarily to purge excess vapor
    • On Columbia 350s, the throttle should be twisted (or pushed depending on if it’s an Avidyne or Garmin Columbia) in while cranking
    • Be prepared to reduce power once engine fires

Beechcraft 36 Bonanza

  • Throttle and Mixture Idle Cutoff
  • Low Boost:  Run for 30-60 seconds.  Reference above temperatures on the non-turbo Cirrus for run times
  • Mixture full forward
  • Throttle open 1″
  • High Boost until fuel flow peaks, then off
  • Crank
  • Once engine fires, Low Boost might need to be engaged momentarily to purge excess vapor

There are other “procedures” for hot starting out there, but most of them involve starting with full throttle, which can lead to the airplane shooting ahead on a ramp or taxi way if the brakes aren’t properly set.  This can lead to high repair costs, so always be cautious.  Figuring out what is happening when the engine is hot will give you a better chance of getting it started right away.
