Reading Weather Prog Charts

There are a multitude of weather products out there today to assist pilots in preparing for a flight.  Aviationweather.gov is the best source for getting all the information a pilot needs for planning a flight.  Aviationweather.gov is the National Weather Service’s source for all aviation related weather products.  When I teach about weather and weather briefings, I recommend to my students to utilize Aviationweather.gov in the planning stages, but still call the Flight Service Station to get a full fledged weather briefing before takeoff.

When preflight weather planning, one of the best ways to get a picture of what is happening over a broad area is utilizing the Low Level Significant Weather Prog charts.  The Prog chart gives a forecasted 12 and 24 hour picture of what type of weather to expect over the US.  The Prog chart gives the expected flight rules, areas of turbulence, and where the freezing level is located.  If you’re looking at the 4 panel view, the Surface Prog chart shows fronts, pressure areas, and areas of expected precipitation.  That covers just about everything, doesn’t it?

I believe the Prog charts are underutilized in planning.  Foreflight and Garmin Pilot have given easy access to radar pictures, satellite pictures, METARs, TAFs, and several other sources of weather information.  But, a lot of the easy access data you can get from those apps is current data (with the exception of the TAF) while a lot of the forecast data takes some hunting around.  So, products like Prog charts aren’t often utilized.

The other problem arises when pilots know about Prog charts, but don’t know how to read them, then don’t know how to find the legend to decipher the chart, the chart is often set aside and quickly forgotten about just because of a lack of knowledge.  Have no fear, though, as now we will use an example 4 panel Prog chart to decipher the lines and colorations.

Low Level Sig WX Prog

Just looking at the Low Level Significant Weather Prog Chart above, it can be a little confusing.  That’s why they make a legend!

Low Level Legend

Coupling the legend with the chart above, we can determine some things.  First, California, parts of the Pacific Northwest, a small part of southern Arizona, and a good portion of the Midwest and East coast are going to have marginal VFR conditions in the next 12 hours.  Wisconsin, Illinois, a good portion of the Northeast, and a small portion of the Pacific Northwest will suffer IFR from IFR conditions.  There are going to be a good amount of low level turbulence in the northern and eastern parts of the country.  Finally, the freezing level starts at the surface running in a jagged line across the midwest states and curling up into the Northeast.

That’s a good bit of information, isn’t it?  If a pilot is planning a VFR flight into the Northeast tonight, it would probably be best to wait for another day, according to this chart.

Now, to see what is causing the conditions above, we need to look at the Surface Prog Chart.

Surface Prog

The green circular areas above show that some form of precipitation is in that area.  The circular dots with the triangle located in Mexico and Baja California are depicting moderate rain showers.  If the triangle was gone, it would just be moderate rain.  In the northeast, all those symbols are showing moderate to heavy snow showers.  Across the plains, we see a lot of high pressure, meaning visibility and nice flying weather.

These charts are invaluable when it comes to flight planning, especially over long distances when the weather could be changing a lot over the period of your flight.  Put them to use the next time you are planning a trip and you’ll learn you have a much better picture of what the weather is doing.

  • Flying the Piper Malibu

    Looking for an airplane with more seats, more useful load, and good speed?  Look no further than the PA-46-310P Piper Malibu.  It feels like a corporate airplane, but this turbo charged piston single is good owner/pilot airplane for taking the family on vacation or using on business trips.

    Piper Malibu Texas Top Aviation

    The original Piper Malibu, which was manufactured between 1984-1988, is a great next step airplane for Cirrus owners, Saratoga or Lance owners, and Mooney owners looking to move up to a pressurized, 6 seat piston.  The pressurization has got to be one of the best parts of the Piper Malibu.  The ability to climb up to the low flight levels (the service ceiling is FL250, but the airplane performs great between 16,000 and FL190) to catch better winds and get a better true airspeed (the airplane gains about 2.5 KTAS for every thousand feet) without having to wear oxygen makes the ride much more enjoyable.

    Equipped with six seats and a 4,100 pound gross weight, the Piper Malibu allows for a lot more carrying ability than a Cirrus or even a Saratoga.  Now, like most piston airplanes, you can’t take 6 average adults, bags, and full fuel, but here’s the great part:  the Continental TSIO 320 only burns 16.5 GPH in cruise at 75% power.  The plane will still fly 200 KTAS at 16.5 GPH.  With 120 gallon capacity, even taking half tanks still allows for a 2.5 hour range with an hour reserve.  At 200 KTAS, that’s 450 miles.  And, you gain an extra 360 pounds useful load at half tanks.  That’s not too shabby.

    Piper Malibu PA-46 Texas Top Aviation

    The Piper Malibu was designed to be comfortable, fast, and be able to carry some baggage.  There are two baggage compartments, one in the nose behind the firewall and one in the rear behind the rear seats.  The nose baggage is wide enough to fit golf clubs in, while the back baggage is large enough to fit rolling suitcases in (the front baggage has no problem with roller bags either).  Lots of weight in bags?  Again, no big deal.  Just plan on taking less fuel and still flying for 2.5 hours.

    From a pilot’s standpoint, the Piper Malibu is a pretty straightforward airplane to fly, though it does require some specialty training.  A lot of PA-46s on the market right now have upgraded glass panels and digital engine monitors, making piloting the airplane that much more streamlined.  Most Piper Malibus are equipped with the KFC 150 autopilot.  Some have a yaw damper installed, others don’t.  Some have the vertical speed and altitude capture installed, others don’t.  It just depends on that specific airplane.  They aren’t like a Cirrus where they are all made the same.

    Looking to upgrade to something with more seats, a higher service ceiling, but not a significant increase in fuel costs?  Look into the Piper Malibu.  You can get one in good shape from about $300,000.

     

  • Simplified Instrument Approach Briefing

    In instrument flying, I am all about keeping things simple.  There is a ton of detail that an instrument pilot can get bogged down in.  When an instrument pilot gets bogged down, he gets distracted from flying the airplane.  When he gets distracted from flying the airplane, dangerous circumstances can happen.

    I like to keep things simple.  When I first started instructing, I developed a very simple instrument approach briefing that captures everything that is necessary on an approach plate, but prevents getting bogged down in the details.

    I call it the BBC instrument approach briefing.  Here it is:

    Brief

    rnav-32-kssfFirst things first.  The first step of an instrument approach briefing is to brief the approach plate.  There are a bunch of acronyms out there that instructors tell their students to memorize that only cause confusion instead of helping get the plate briefed.  To keep it simple, just work your way across the plate and you’ll get all the information you need.

    Start in the top left hand corner of the plate, with the approach course, then work your way right and down, as follows:

    • Approach Course (or Nav frequency if flying a VOR/ILS/LOC)
    • Runway information
    • Notes (these are good to brief the night before as a lot are irrelevant to GA pilots
    • Missed approach
    • Frequencies
    • Planview and MSA
    • Profile View and Minimums

    Simple enough, right?

    Build

    Now that you know what you are planning on doing, you can now take the second step in the instrument approach briefing and build the approach in your GPS.  You know your approach type, you know your transition, and you know what your minimums are.  Taking all that information, you can now build it in to your system.

    Checklists

    Once everything else is done, don’t forget the checklists.  The descent and before landing checklists still need to be done as part of an approach.  The best time to do these is before joining the approach so that you don’t have to worry about flying the approach and looking at a checklist at the same time.  Even better, memorize the checklist and you don’t have to look at anything!

    Most importantly, you want to be configured properly for the approach by the final approach fix.  Gear, flaps set, power set, so all you have to worry about at that point is following the needles and trusting your instruments.

  • A Proper Cross Country Flight Checklist (Part 1)

    I love cross country flights. Airplanes are designed to travel.  When I was instructing private students, my favorite lessons were always the first cross country flights. I looked forward to getting my students out of the pattern, away from the practice area, and showing them what they could really look forward to as a private pilot.

    When I was in college, my friend and I borrowed his dad’s Cessna 150, did a cross country flight in it from Indianapolis to Kitty Hawk, then down the coast to Florida. We camped in the grass next to the airplane wherever the airport managers would let us and had our own aviation adventure complete with mechanical problems, unexpected weather, and interesting people along the way. These types of trips have produced some of the best memories and experiences that I’ve acquired during my aviation career so far.

    Unfortunately, I know many people whose only cross country flight experience is what was necessary to satisfy their Private and Instrument training requirements. Some of them are nervous about the idea of venturing away from the familiarity of their home airport, while others are relatively new pilots who simply don’t know where to start planning a long cross country flight.

    I’ve taken some notes on my preparations for an upcoming cross country flight that I’ll be flying in my dad’s Bonanza. I’m hoping this checklist might help others feel a little more confident that they have everything they need to get going.

    Oil

    Its always a good idea to bring a few extra quarts of oil. If you stop somewhere and find you need some, its nice to have the right kind on hand. Never assume that the airport you’ll be landing at next will have oil available.

    I like to keep a few extra quarts of 15W50 in the back of the Bonanza, just in case (photo from oil-store.com)

    Fuel Stops

    Here is an example of the 100LL price tool as seen on the Foreflight maps page
    Here is an example of the 100LL price tool as seen on the Foreflight maps page

    I’ve learned the hard way that calling ahead to verify fuel availability can be extremely important. I landed at an airport in Ohio one beautiful Sunday morning to find that the FBO wouldn’t be open until much later in the day. Naturally, there was no other fuel available on the field. I hadn’t called ahead to verify the hours of fuel availability (I assumed they had Self Serve) and had only 2 options: wait a while for the FBO to open, or try and find somewhere else nearby that had gas. As far as price, www.100LL.com is a valuable tool for finding cheap fuel. Foreflight also has posted prices for 100LL and Jet A, but it’s still a good idea to call ahead and verify price and availability.

    Batteries for electronics

    It’s miserable to run out of batteries for a noise canceling headset with hours remaining in your flight. Bring spares, not only for your headset, but for your flashlight and other gadgets as well. Make sure your hand held GPS, iPad, and Stratus are charged (if you have them). I like to carry a charge cable and adapter as a backup so that I can plug things into the cigarette lighter.

    Jumper Cables

    We always carry the ground power cable in the back of the Bonanza just in case we ever need a jump. Last month, when I was flying down to Texas, I was glad I had them; we had a dead battery after our fuel stop and had to borrow some power from an FBO worker’s pick up truck. Don’t assume that wherever you are stopping will have the correct cable to jump your airplane, especially if it requires a specific plug.

    These are the cables we keep in the back of the Bonanza (photo from airchief.com)

    Parking Fees

    Every airport is different. I like to call ahead and find out how much the FBO is going to make me pay in landing/overnight fees. When I flew up to Buffalo last summer, I paid 25 dollars for parking at Niagara International (IAG). Had I parked at Buffalo (BUF), they would have charged me over $200.

    Approach plates and charts

    Make sure you have current approach plates and charts either physically available or downloaded before you blast off. Having a copy of an AFD is a good idea as well, be it digital or paper.

    Rental cars

    If you arrange it beforehand, many FBO’s will have the car ready for you upon arrival. You may also be able to drop the car off at the FBO when are finished, instead of taking it back to the rental agency. It sure is nice to have the car pulled up next to the airplane when it’s time to unload.

    Hotels

    Bigger FBO’s may have discounted rates with local hotels. If you call the desk and explain your needs they may offer to book it for you, or at least point you in the right direction. It may be worth picking an airport with more expensive fuel if it puts you closer to the hotels or restaurants you want to go to.

  • MMOPA Spring Safety Standdown

    MMOPA will be hosting it’s second Safety Standdown event at many locations across the country for Piper PA46 owners and pilots. The first iteration of MMOPA Safety Standdown in the fall of 2019 was a big hit. Each event was very well attended by MMOPA members.

    What is Safety Standdown you ask? Safety Standdown was put together as a mid-year training event as part of the MMOPA Master Aviator program. It’s goal is to allow PA46 owners and pilots to fly in to a location at a reasonable time (the event starts at 10am local time), received some good quality ground training over relevant safety topics by highly experienced PA46 instructors, have a free lunch, then depart mid-afternoon to arrive back home before dark.

    The event is free to all attendees. Lunch will be provided at each location. This event is not exclusive to MMOPA members, either. Any PA46 owner or pilot, or just anyone interested in the PA46 world, are invited to attend.

    Texas Top Aviation is hosting the South Central Region Spring Safety Standdown at the Henrickson Jet Center at the Austin Executive Airport (KEDC). Hank Gibson and Pedro Vargas-Lebron will be presenting on the following topics:

    • MMOPA Operational Practices review and importance of stabilized approaches
    • Crosswind Takeoffs and Landings
    • High Density Altitude Operations
    • A discussion of thunderstorms, resources in the cockpit for weather avoidance, and accidents that have occurred involving thunderstorms

    The MMOPA Spring Safety Standdown will take place on Saturday, April 18th, 2020. Registration is required for the event. The link for registration can be found here.

    Come on out for some high quality training and free BBQ with 50 of your closest PA46 buddies!

  • Beware of the Lunch Monster

    He prowls around, preying on innocent pilots.

    He’s very sneaky, creeping unexpectedly and attacking after the propeller begins to turn.

    He’s very cunning, veiling his intentions until, BOOM, he attacks.

    Beware of the Lunch Monster!

    Whenever I am doing a full day of training (which is usually how transition training courses are planned out, in full day sessions), I always plan a lunch stop.  My metabolism has the speed of a rocket ship, so I get hungry and need some sustenance in the middle of the day.  I have a running list of airports to stop at that have good lunch spots at them or nearby, so my customers and I usually end up at one of those airports.

    Almost without fail, if a customer is having an excellent flying morning, nailing all the procedures, picking up all the techniques, and overall, flying pretty well, then eats lunch, the afternoon doesn’t go quite as well.  Doing some of the same things we did that morning, but the customer’s performance isn’t quite as good.  Most of the time, it’s just a brain lockup or landings aren’t quite as squeaky as they were in the morning.

    Part of it is fatigue after flying for 2-3 hours in the morning.  The other part is what I call the Lunch Monster.  Eating a big lunch can sap away brain power and cause a person to lose energy around 2-3pm, leading to an afternoon lull (or the Lunch Monster attacking!).

    According to Forbes.com:

    Diet contributes to energy levels too. “Eating a lunch that is too big is the most common reason for feeling sleepy in the afternoon,” says Rebecca Solomon a nutritionist at Mount Sinai Hospital in Manhattan. “All your energy goes into digesting the enormous meal.”

    The goal is to keep the body’s Cortical and Cortisone levels even since they’re the hormones released by the body in reaction to stress–they produce the fight or flight response. Their levels are elevated when you have sugar, caffeine and processed food, so you feel awake and energetic. But a few hours later, when those levels drop, you’re sluggish.

    Solomon recommends eating a meal that’s balanced with healthy fats (from olive oil or avocados, for instance) with protein and healthy carbohydrates (whole wheat bread or pasta). The portion will vary for people of different sizes, but a general rule is you should be hungry about four hours after the meal.

    Another healthy eating habit: Consume small portions of foods throughout the day, including almonds, carrots and hummus and fruit. Enjoy lunch around 1:30 or 2 p.m., just before the time you normally feel fatigued.

    Now, most of the stops on my list of restaurants don’t fit the bill of healthy fats and healthy carbohydrates (plenty of protein, though, especially the BBQ joints).  For those days, bringing along a snack like almonds or dried fruit is a great idea to munch on mid-afternoon.  Trimming down the amount eaten at lunch helps a lot too.

    So, the next time you have a long day of flying or training, beware the lunch monster and prep some good snacks when your flight instructor says you’re stopping for BBQ!

  1. I think you left out an important part of the picture. Maybe it’s there, but I can’t find it. The question is WHEN?
    The footnote tells when it was issued, but not WHEN it applies. Is it a statement of present conditions? Or is it a forecast of conditions at some future time? Somewhere that information is available, but I can’t find it.

    1. Hi Albert, at the bottom of the Prog Chart itself, there is an issue time, then directly below it, there is a valid time. That valid time is when it applies. Surface Analysis charts are current, but Prog charts are always forecast. Unless of course, they haven’t been updated, then it’s showing what was supposed to take place in the past.
