Cirrus Braking Systems: A Hot Topic

ByZach Anderson March 5, 2021April 30, 2021

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.

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.

FltPlan Go
ByHank Gibson August 10, 2016August 27, 2016

I am an iPad user, but I have an Android phone. I had been using a junky aviation weather app that just gave meters and TAFs, but seemed to have been programmed in a foreign language (un-decoded TAFs notwithstanding). I wanted something more robust, but didn’t see the need to pay for a Garmin Pilot subscription since Foreflight on my iPad was my main EFB (Electronic Flight Bag) I use in the airplane.

When I upgraded my phone, I decided I had to find something better. I have a WIFI only iPad, so I utilize my phone to take quick glances at weather reports or when I want to see the radar without having to tether my iPad to my phone. The app I had wasn’t cutting it.

That’s when I found FltPlan Go. We are all familiar with FltPlan.com. It’s what a lot of corporate pilots use to file flight plans. I’ve used it some, but there is a large amount of data it needs to set up an airplane. Since I already have all the airplanes I need in Foreflight, I don’t use it that much since I didn’t want to do the setup. It is rather handy as it spits out flight logs and has a lot of pre-loaded performance numbers for different makes and models.

FltPlan Go is FltPlan.com‘s app. It is very user friendly, easy to use, and, most importantly, free! You can get METARs, TAFs, NOTAMs, Airport Diagrams, approach plates, full weather reports for airports including radar, maps, and a whole lot more. As far as I can tell, it is a full fledged EFB. I haven’t really scratched the surface on all the features in using mine, but it is quite robust from the little bit of poking around I’ve done.

I’m still a Foreflight guy, but if you want something else or you have an Android phone and don’t want to pay for Garmin Pilot or WingXPro, check out FltPlan Go. It’s a winner.
An Educational Runup
ByHank Gibson July 23, 2020July 17, 2020

When a pilot thinks of an engine runup in a single engine piston airplane, typically it is let’s find out if the engine is running rough or not, meaning a spark plug is fouled. Believe it or not, there is a little more to learn from a runup than just checking the spark plugs.

A distinct advantage to having an engine monitor that monitors all EGTs and CHTs is you get a better idea of engine health. When switching to one magneto or the other during the runup, all the EGTs should rise, showing that the temperature of the exhaust gas is going up from each cylinder. This occurs because when running on only one magneto and one set of spark plugs in each cylinder, the mixture takes longer to burn, so, when the exhaust valve in the cylinder opens, the burn is still on going and this hits the EGT probe, causing a temperature rise. An indication of a magneto failure in flight would be a rise in all the cylinders EGT without a change in mixture setting.

Now that we know what to look for when checking each magneto, what would one look for to show that there is a problem? The basic that each student pilot is taught still applies. The engine manufacturer puts a limit on RPM drop during the runup. When checking one magneto or the other, watch for an excessive RPM drop. If the RPM drops past the limit, this usually will be accompanied by engine roughness.

Why is that? Let’s look at the cause for the excessive RPM drop. For this, we need to go back to our EGT indicators. Let’s say we have a 6 cylinder engine. When the key is turned to the right magneto, the RPM drops 250 RPM and the engine gets very rough. Look at the EGT gauge. The cylinders where the spark plugs are firing normally will all show a temperature. The cylinder (or cylinders) where there is no combustion, meaning a bad plug, will show no temperature. This is because the mixture is just sitting in the cylinder and not igniting, therefore, no exhaust gases will be pushed out so there will be no EGT indication for that cylinder. This is also how you tell a mechanic which cylinder to check for the bad plug.

It could also be a bad magneto. If multiple cylinders EGT all drop, or the engine wants to quit entirely, you have a bad magneto or bad ignition harness.

What else can you learn during the runup? Electrical system health is key, especially in all electric airplanes (meaning no vacuum system). It’s a very good idea to turn on all the lights and pitot heat to ensure that a rise is indicated on the ammeter. This means the alternator is carrying the load and working properly.

The next time you do your runup, keep an eye on your EGT to see the rise during a magneto check.
Cirrus Vision Jet Receives FAA Certification
ByHank Gibson November 8, 2016

The long anticipated certification of the Cirrus Vision Jet finally happened. On October 30th, the FAA awarded certification to Cirrus’ single engine jet. Marketed as the world’s first single engine personal jet, the Cirrus Vision Jet will seat five adults, two children, and cruise around 300 knots.

The Williams FJ33-5A Turbo Fan engine is operated by a FADEC, single handle throttle, similar to the throttle in the piston powered Cirrus family. In fact, the SR series was taken into consideration when designing the Cirrus Vision Jet in order to simplify the upgrade for pilots. Many of the buttons and knobs are in the same places in the Cirrus Vision Jet.

The Cirrus Vision Jet is equipped with the Cirrus Perspective Touch by Garmin that is very similar to the Cirrus Perspective by Garmin in the piston powered line. Equipped also with the Flight Into Known Icing system and the Cirrus Airframe Parachute System (CAPS), both of which are standard.

Unlike the piston powered Cirrus lines, the CAPS system on the Cirrus Vision Jet is actually mounted in the nose. Also, unlike the piston lines, the jet CAPS is integrated with the aircraft avionics to slow the airplane to between 67 and 160 knots when the system is activated. In the jet, the CAPS system was designed to withstand higher weights, higher speeds and higher altitudes.

Cirrus hopes to start deliveries of the Vision Jet by the end of the year, with many more rolling off the line in 2017. All Cirrus Vision Jet pilots will need to be type rated in order to fly the aircraft. Cirrus is doing all the type rating training in house at their new Vision Center in Knoxville, Tennessee.

Medical Reforms Get Passed
ByHank Gibson July 17, 2016July 22, 2016

On July 15th, the medical reforms that AOPA and many other aviation advocacy organizations had pushed so hard for were passed into law. President Obama signed the medical reforms law on the 15th, but, before practical application of the law takes place, the FAA has to translate the law into regulations.

What do the new medical reforms mean for medical certificates and flying? First, you still have to get a medical examination at some point in your flying career. Student pilots will still need an initial medical examination. Initially, for pilots who have held a medical certificate at some point over the previous 10 years, a new medical examination may not be needed (this still has to be regulated by the FAA so exact details aren’t known yet).

So, if you’re medical certificate has expired but you have had one in the past 10 years, you qualify. But, if you have had your medical certificate revoked, suspended, withdrawn or denied, you don’t qualify.

Once that student pilot receives the initial medical certificate (or the experienced pilot decides to start flying again), all that needs be accomplished is to take a free, online course on aeromedical factors every two years and meet with a physician at least once every four years.

There are some operating limitations that will be put into place for folks operating without a third class medical. Pilot’s can operate aircraft with no more than 6 seats that weigh less than 6,000 pounds, can carry 5 passengers, and are able to operate in day or night VFR or IFR conditions. Pilot’s may not operate for hire, nor climb above 18,000 feet or fly faster than 250 knots.

It will take some time for the FAA to put the regulations in place, but the process has begun.

A Proper Cross Country Flight Checklist (Part 1)
ByAndrew Robinson February 8, 2016February 11, 2016

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

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.

Come back next month for Part 2!
