Cirrus Autopilot Check

In the Pre-Takeoff Checklist for any Cirrus aircraft, it calls for pilots to perform a Cirrus Autopilot Check.  It is prudent to check the autopilot before your flight to ensure that all aspects of the autopilot are working properly.  The only problem is, the checklist doesn’t spell out how to perform the Cirrus Autopilot Check.  You would have to go to the POH for the airplane, which is usually in the back seat or a bag somewhere and therefore hard to get to, in order to find the procedure.

The procedure for checking the autopilot is slightly different depending on what autopilot is in your airplane.  The procedures for all three are below.

S-TEC 55x

  • Sync the heading bug to your current heading
  • Activate heading mode on the autopilot
  • Twist the heading bug left and right to ensure the ailerons move left and right
  • Sync the heading bug to your current heading
  • Activate vertical speed mode on the autopilot
  • Move the vertical speed bug (or the vertical speed on the altitude pre-selector if you have a steam gauge Cirrus) up and down to ensure the elevator moves accordingly
  • Ensure you can overpower the autopilot
  • Press the autopilot disconnect switch to ensure the autopilot shuts off

 

Avidyne DFC 90

  • Press the AP button to activate the autopilot
  • Ensure AP, ROLL, and PITCH Annunciations are depicted in green on the top of the PFD
  • Set the heading bug 90 degrees from the current heading
  • Press the HDG button on the autopilot
  • Ensure the ailerons are moving in the proper direction and HDG is annunciated on the top of the PFD
  • Ensure you can overpower the autopilot
  • Press the autopilot disconnect switch on the stick and ensure the autopilot has disconnected

  • How to Get the Current Weather

    For a long time, I was happy if an FBO had a radio where I could tune the ATIS or automated weather before getting into the plane. This would allow me to skip listening to the weather in the airplane with the engine running, giving me a quicker exit from the ramp while burning a little less fuel. I would also be able to brief my taxi route from the ramp since I would know which runway was in use before getting in the plane.

    As we progress forward in technology, I’m constantly amazed at how much more planning I can do from the palm of my hand. Now, I can call a phone number and get the ATIS, AWOS, or ASOS, depending on the size of the airport; if you prefer reading a text version…well, there’s an app for that.

    With this technology, it’s very important for pilots to be aware of what service they are utilizing when calling these numbers. Usually only a Class B or larger Class C airport will have a phone number specifically for ATIS as well as one for AWOS/ASOS. These are listed in the Airport/Facility Directory (AFD), as well as all flight planning apps (Foreflight, Garmin Pilot, Stratus Insight). More then one pilot has called the AWOS/ASOS number for an airport thinking they would receive the ATIS (because towered airports that have ATIS phone numbers often also have AWOS/ASOS phone numbers that are different). Since the pilot didn’t hear a code on the phone, that led to the false thinking that either the tower was closed or the pilot did not have the code (ie. Information Bravo) to give to ground control when calling for taxi instructions.  The minute weather can be very useful for flight planning, but the ATIS must be received before contacting ATC at a towered airport.

    Notice the red box just past halfway down the page. There is a phone number for the ASOS at KSAT and a separate phone number for the ATIS next to the frequency.

    Sometimes, you may get a busy tone if someone else is on the line. Usually, waiting a few minutes and trying again will lead to success. Just like old school phone lines, only one call can go through at at time! If it’s a particularly stormy day, you may be fighting a number of pilots to get on the line. In this case, an app where you can read the ATIS may be particularly helpful (Yes, there actually is a dedicated ATIS App!).

    The ATIS app allows us lowly pilots without an Aircraft Communicating and Reporting System (ACARS) to access the Digital ATIS (D-ATIS ) at airports where ATIS is available. Only 76 airports in the US have D-ATIS, most of which are either Class B or busier Class C airports. Foreflight also provides D-ATIS textually at the same 76 airports, though it is only accessible depending on which subscription level you have with Foreflight (since I’m not a Garmin Pilot or Stratus Insight user, I’m not sure if either of them give D-ATIS reports).

    ATIS App Symbol

    With Foreflight’s D-ATIS, it does not get updated over ADS-B, only when your iPad or phone have an internet signal. When inbound to an airport with D-ATIS, the pilot has to listen to the radio frequency to get the current ATIS. Foreflight will display the last D-ATIS it received, but typically, it’s old. Check the time in the upper right hand corner.

    Foreflight now offers Pre-Departure Clearance (PDC) at those same 76 airports. With either a pre-registered tail number or a Foreflight call sign (starting in FFL), once a pilot files an IFR flight plan, the D-ATIS and the IFR clearance in it’s entirety are texted to the phone number the pilot filed with. All that is left to do is call ground, state “I have information Romeo and my clearance, ready to taxi,” then away you go. Skipping listening to the ATIS and talking to Clearance Delivery saves a good 5-10 minutes at times, depending on how busy the airport is.

    These days, there are many different avenues to get the current weather (and IFR clearances!). When calling on the phone, the key is to be aware, know which number you are calling and, if you are expecting to hear an ATIS message but instead hear the AWOS/ASOS, verify the Chart Supplement Guide and Notices to Airmen (NOTAMS) to check tower hours of operation before flying into the airspace. 

  • MODAERO NextGen Aviation Festival

    Looking for something different to do this Spring Break week?

    Modaero

    Consider checking out the First Annual MODAERO NextGen Aviation Festival in Conroe, TX.  It’s a fly in event, complete with camping opportunities, at the Lone Star Executive Airport, KCXO.  The festival itself is being held right next door to the airport at the Lone Star Convention Center.

    What’s the draw, do you ask?  Not only are there going to be representatives from all the major aircraft manufacturer’s (along with tons of airplanes), there will be a multitude of speakers and live music.  There are even drone races!  The live music sets the event apart from the well known national fly in events like Osh Kosh and Sun N Fun.  It’s a different type of Festival, geared toward the younger generation of pilots.

    For more information or to register, check out MODAERO’s website.  The festival runs from Wednesday through Saturday, March 16-19.

  • Angle of Attack (AOA)

    You are hand-flying an in-the-weather descent, power back, heading for the FAF. You start a 30 degree banked turn at your lead point to cross the FAF, when your passenger behind you gasps. Looking over your shoulder, you see he has spilled his drink into his lap…too bad for him! However, when you turn your head back to your panel, your inner ear tumbles and you see 45 degrees of bank, 15 degrees nose low, airspeed increasing.

    Congratulations! You have managed to get distracted and sucked into an unusual attitude recovery. By the book, you should roll wings level, pull to the horizon, and adjust power as necessary to keep the airspeed within limits. In this scenario, if you had not experienced vertigo, you might have been able to roll to less than 30 degrees of bank, recover your turn, pull the nose up to less than the original descent attitude, pulled a bit of power to slow back to your desired penetration speed and then resumed your desired ground track. However, this would only be appropriate if you had full situational awareness as to the deviations caused by the look over your shoulder, plus full confidence that the moderate corrective actions would put you back on your desired flight path.

    As a military aviator, I learned unusual attitude recoveries based upon hard maneuvering at extreme pitch and bank angles. In the hard-maneuvering environment, an unusual attitude could be 90 degrees straight up, airspeed decreasing below 120 kts…or 80 degrees nose low, 135 degrees of bank, airspeed increasing through 500 kts… etc. In these cases, understanding angle of attack, or AOA, is critical to maintaining controlled flight and returning to a normal attitude.

    In an extreme nose-high attitude, a military aviator is trained to roll the aircraft to 90 degrees of bank, ease off the back-stick pressure to reduce AOA, add power as required, and allow the nose to slice back towards level, rolling to wings level as the nose approaches the horizon. If nose low, the recovery procedure is to roll rapidly, within asymmetric g limits, until wings level, then to pull at optimum g loading to recover to level flight. For the nose-low recovery, power was normally reduced until airspeed could be assessed and brought under control. However, when doing the nose-low pullout at 7-9 gs, pulling the power for too long would leave you much to slow to resume combat.

    The AOA gauge on a fighter’s glare shield is a primary reference during hard maneuvering and for landing. The AOA for optimum maneuvering is 13 degrees, displayed as the green circle or “green donut” on the gauge. The red chevron on top represents a slow condition of 15 degrees or more and the yellow lower chevron represents 11 degrees or less.

    For normal landing in the F-16C, the pilot slows to 220 kts and configures abeam the touchdown point while mentally computing the final approach airspeed of 136 kts plus 4 additional knots for each 1000 lbs of fuel. When rolling off the perch and flying the final turn, the pilot would usually only glance once at the airspeed once to ensure final turn airspeed of 180 kts while using the AOA sight gauge as the primary indicator of a best performance turn. As long as the AOA was green donut (13 degrees) or less, you would not stall. If on speed and 13 degrees wasn’t going to get you around the turn to line up with the runway, you knew you were going to overshoot. You never wanted to see the red chevron of 15 degrees or more as that meant you were too slow, pulling too hard, and in danger of building an un-recoverable sink rate!

    Few GA aircraft are currently equipped with AOA indicators, though there are several after market devices available for retrofit. However, knowing the impact of AOA and how to manage it is vital to safe aviating, even without an AOA gauge. The bottom line is, as long as you don’t ask the wing to produce more angle of attack than it can handle, you won’t stall.

    Practicing final turn stalls, to know what the wing feels like as you get too slow or pull too much on the controls, increasing AOA past the critical point, will keep you safe when you encounter that unexpected overshooting wind or you find yourself inadvertently on too tight of a downwind leg. Better to overshoot or take it around to try again, than to pull too hard and exceed critical AOA.

  • Beechcraft Bonanza Ownership

    If you walk up to any Beechcraft Bonanza sitting on the ramp at an airport and ask the owner, “How do you like your Bonanza?” be prepared to stand there and listen for 15-20 minutes while he brags about his airplane.

    V35 Bonanza

    The thing about Beechcraft Bonanza owners is that they are almost a part of a cult. They will tell you up and down why the Bonanza is the best airplane out there. They’ll tell you why all the others don’t even come close. They’ll tell you about the payload, the six seats, the variety of configurations you can select from, the ability to land pretty much anywhere. By the time you walk away, you will probably be convinced to buy one yourself.

    Bonanza’s are great airplanes. For those of you new to the single engine piston market, a good comparison for a Beechcraft Bonanza would be a Suburban. Not the flashiest ride out there, but extremely capable, comfortable, and family conscious. If you’re hauling a load, you’ll take a Bonanza over a Cirrus or Mooney any day. Have six people? No problem!

    One of the best things about a Beechcraft Bonanza is the variety of designs. Four seats, six seats, long range tanks, tip tanks, turbo charged, normally aspirated, steam gauge, G1000, Aspen or G500 retrofitted, dual yoke, single yoke, leather, cloth, and a variety of different colors out there on the market make finding a Bonanza that fits your need pretty easy.

    When it comes to picking out an airplane, the first question is always the mission. If you’re thinking about a Beechcraft Bonanza, you’ve already determined you need something with a good useful load. Do you need four seats or six? Depends on how often you’ll be carrying someone or how new of an airplane you want. Older Bonanzas have four seats, but a lot have had significant updating. Newer A36 and B36 Bonanzas have six seats, but are going to cost you more.

    Beech Bonanza

    Do you need a turbo charged Bonanza? If you’re in a high elevation area or expect to visit the mountains a lot, then absolutely. If you want a better cruise speed and don’t mind a little less useful load, then go for it. If you’re more concerned about being able to load it up and you aren’t going to cross the Rockies often, then normally aspirated is what you want. You’re probably looking at about 160-170 KTAS with the normally aspirated whereas you get between 180-190 KTAS at altitude with the turbo.

    Do you need tip tanks? Tip tanks have two advantages. One is the most obvious: you get to carry more fuel, therefore you get to go farther without having to stop (or when you stop for the bathroom, you don’t have to fill up with gas). The other advantage is you get a bump up in useful load. I talked to a Beechcraft Bonanza owner a few weeks ago who had tip tanks on his. He told me max gross on his Bonanza was 3,800 pounds and was eligible for an upgrade of up to 4,000 pounds and all it took was paper work for the STC. That’s quite a bit of load!

    G36 Bonanza

    Are Bonanzas hard to fly? When moving up from a typical 172 or Cherokee that most people learn to fly in, it does take some adjustment. But, with good Bonanza training from a qualified Bonanza training instructor, then the transition is no problem. There are tons of resources out there to aid all future and present Bonanza owners in their foray into the Bonanza nation. With the American Bonanza Society and Bonanza Pilot Training, there is no lack of training, thoughts and opinions.

    In need of an airplane that can pretty much do whatever you need? Then a Bonanza may be right for you.

  • The PIC Isn’t Always the Pilot Who Took Off

    You are at cruising altitude and your flight is going just as planned. All of that can change, sometimes without much warning, and you, the non-pilot, are now in charge. Would you know what to do?

    This was a scary thought for me until I attended a seminar developed for the non-flyer at a Cirrus Owners Pilot Association (COPA) fly-in. Cirrus is the only small plane with a parachute as standard, so I thought all I had to do in an emergency was pull the chute. It’s a little more complicated than that!
    I learned the vast majority of pilot incapacitation happens when the plane is at cruising altitude, so there is time to find a solution.

    anne-pargeter-picture

    I was taught ten basic steps to follow to bring the plane safely to the ground.

    • First attempt to revive the pilot. If he is choking, it is possible to do a Heimlich maneuver from the side. This may dislodge whatever is blocking his airway and solve the problem. If he is experiencing hypoxia, turn off the heat, open all vents, and, if you have on board oxygen, use it. Also, if you can, get instructions on how to descend to a lower altitude. If the pilot is unconscious due to a heart attack or other medical emergency, there are still things you can do from the right seat.
    • Engage the autopilot if it isn’t already on and move the pilot off the controls. *
    • Ensure you are connected to the radio. If you hear ATC or other pilots, you are.
    • Send an electronic trouble message. Set the transponder to 7-7-0-0 to identify your plane to ATC. This will cause your plane to be highlighted on ATC radar screens.
    • ATC will most likely contact you asking what is your emergency. If this does not happen, you will need to transmit a Mayday call. All non-pilot passengers should know how to use the radio to get help, if they know nothing else.
    • With help from ATC, decide where you want to go.
    • Use the autopilot to fly in the direction suggested by ATC. I was taught that ultimately the choice of where to deploy the parachute is up to me because I am now the PIC, pilot in command.
    • Ensure that seat belts are secure and the emergency hammer is between your legs (so you have it to break a window to escape if needed).
    • Pull the parachute handle.
    • On the way down, shut down the engine and brace for impact.
    • After landing, move away from the plane, into the wind. Stay nearby and wait for help.

    The seminar covered specific procedures to accomplish these basic steps, what to do if you don’t get a response from ATC, what to say in a Mayday transmission, how to fly a heading, how to check fuel levels, shut down the engine, etc. After the seminar, I felt much more comfortable about what to do if my pilot suddenly lost consciousness.

    I was also told to practice what I had learned to avoid panicking in an emergency situation. There are so many things the person in the right seat can do under normal circumstances to practice. Learn how to set heading bugs, learn where the plane’s Electronic Locator Transmitter (ELT) is located and how to activate it. This will help rescuers locate the airplane. Learn how to assess your fuel levels. Practice making routine radio transmissions. Observe what your pilot does and ask questions if you don’t understand something.

    Knowing what to do in an emergency situation will give you a sense of control over what will happen to you, your pilot, and any passengers on board your plane. If you have never considered taking a lesson or two for the non-pilot, find yourself an instructor, and learn what you need to know for your plane. Hopefully you will never have to use it, but if you do, you will be ready to be the PIC who lands the plane.

    Anne and her husband Stephen are the proud owners of a Cirrus SR20. They plan to put the airplane to better use once Stephen retires. Anne has a background in desktop publishing and writing.
