On March 30th, Texas Governor Greg Abbott issued an Executive Order mandating that all travelers (including Texas air travelers operating or traveling in private aircraft) from the following designated areas were to self-quarantine for 14 days (or the extent of their stay in Texas, whichever was shorter) upon entering the State:
California
Louisiana
Washington State
Atlanta, Georgia
Chicago, Illinois
Detroit, Michigan
Miami, Florida
If you traveled to Texas by air from any of the above designated areas, you are required to fill out the Arrivals from Areas Designated for Mandatory Self-Quarantine Form. Failure to do so could lead to a $1,000 fine or 180 days in jail, or both. For private aircraft owners/operators, put your Tail Number in for Flight Number and “Private” for Airline.
Aircraft owners, stay away from the designated areas listed above and you won’t have any worries. A lot of you reading this are from Texas, so make Louisiana a fly over state for now and don’t make any landings in Cajun country.
There was a bill introduced in Congress recently to take control of Air Traffic Control away from the FAA and give it to a private, for profit, corporation. The initial reaction of pilots is “Ahhh! User fees!” which we are all adamantly opposed to. There are a myriad of reasons why this is a bad idea (the “Flying” article makes a comparison to giving NASA to Richard Branson and Jeff Bezos) and we as pilots should be against it.
One of the first questions a student pilot asks me when starting the cross country portion of his or her training is, how do I know what altitude is best for my flight? This is a good question, because without taking certain aspects of the flight into account, it’s really just a crap shoot when selecting an altitude. Craps and flying don’t mix, so let’s take a look at a few considerations when selecting an altitude.
Sky Coverage
Sky coverage has several subcategories when it comes to selecting an altitude. First is how high are the bases? Is it IFR (VFR pilots would be grounded), marginal VFR (1,000 AGL to 3,000 AGL ceiling), or good VFR (above 3,000 AGL ceiling)? If the cloud deck is only 2,500 feet off the ground, then VFR pilots are limited to either 1,000 AGL to 2,000 AGL. This is an excellent segue into why VFR pilots shouldn’t scud run!
Second, what kind of cloud deck is it? Is it an actual ceiling (broken or overcast), or is it a scattered layer? Few or scattered layers usually allow VFR pilots to find a hole to get higher to some smoother air, making the flight more pleasant. VFR pilots, always make sure to check the destination weather as it could be scattered where you are departing from, but it might be broken or overcast where you are arriving.
Last, how high are the tops of the clouds? Pilots can only get this information in the planning stage from the area forecast or from pilot reports, so most of the time, it’s not very precise information. If the tops are at 10,000 feet and the pilot is flying a 172 on a 30 mile trip, it doesn’t make much sense to get on top of the clouds.
Terrain and Obstacles
Terrain goes hand in hand with sky coverage. If there are low clouds and high terrain, that doesn’t bode well for trying to stay VFR and not hitting anything. Obstacles need to be taken into account too, as there are some pretty tall radio towers that can stretch up into a 1,500-2,000 AGL deck of clouds.
Winds Aloft
Once the sky coverage and terrain have been considered, it’s time to look at the winds aloft. Tailwinds are preferred, but, sometimes, a headwind is the only option. After taking the clouds and terrain into account, this narrows down your altitude to a handful of options. The winds aloft will further narrow it down.
Aircraft Performance
Once you have two or three altitudes in mind, taking a look at the performance charts for your airplane will help nail down that final altitude. Pull out the POH, compare fuel burn and cruise speed, and you’ll have your altitude selected.
Figuring out the pattern altitude at an airport should be pretty simple, right? But, in this day of helpful technology, most pilots actually get it wrong. How can you always get it right? Well, it just takes about an extra 15 seconds. Here’s how.
John Wayne Airport Traffic Patterns
As outlined in the Aeronautical Information Manual, section 4-3-3, “traffic pattern altitudes for propeller-driven aircraft generally extend from 600 feet to as high as 1,500 feet above the ground.” Further, in the Pilot’s Handbook of Aeronautical Knowledge on page 13-10, it states: “1,000 AGL is recommended pattern altitude unless established otherwise.”
Okay, so for piston driver’s, we’ve got it narrowed down to 1,000 AGL (Above Ground Level for those who don’t like acronyms). But wait! There’s that very important phrase at the end of the last quote: “unless established otherwise.” That means not all airports have traffic pattern altitudes of 1,000 AGL, or else they wouldn’t put that line in there!
How do you find out what the TPA (Traffic Pattern Altitude) is for a certain airport if it’s not 1,000 AGL? Great question! Your first guess is probably to look on Foreflight. Though this is a good start, it is not the full answer.
Let’s use an example. Look up KAQO, the Llano Airport on Foreflight. At the top of the page, the airport elevation is stated as 1,101′ MSL and the pattern altitude is stated as 1,902′ MSL. From what we just learned, 1,902′ MSL is not 1,000 AGL, so is 1,902′ MSL otherwise established?
On the Airports page with KAQO pulled up, tap the A/FD tab, second to last on the left. Scroll down to Llano Muni. Read the whole entry. Does it state in the entry that pattern altitude is different than 1,000 AGL? It sure doesn’t. So, because it is not otherwise established, pattern altitude at KAQO is 2,102′ MSL not 1,902′ MSL.
Where did Foreflight get that? I have no idea. Too often, though, pilots look at the Foreflight pattern altitude and don’t actually check the Airport Facilities Directory (A/FD). Then, they get the pattern altitude wrong.
What does it look like when pattern altitude is otherwise established? Look up KSGR, Sugar Land Regional, on your Foreflight app. Foreflight states the elevation as 82′ MSL and the Pattern Altitude as 1,000′ MSL. Is this correct? Well, tap that A/FD button again and let’s find out.
On the second line of the A/FD entry, it says TPA-See Remarks. Down in the remarks section, we find the following:
TPA-1000 (918) single engine piston acft, TPA-1500 (1418) for twin and turbojet acft, TPA-500 (418) for helicopters within 2NM.
Foreflight got it right this time for single engine pistons, but if you are in a twin, the pattern altitude is different. What’s the lesson here? Always check the A/FD and don’t always go by what Foreflight says. The A/FD is always right and usually has a little more detail to help set you straight.
One last thing. Both the AIM and the Pilot’s Handbook of Aeronautical Knowledge, when talking about pattern altitude, state, “When operating at an airport, traffic pattern altitudes should be maintained unless otherwise required by the applicable distance from cloud criteria in…section 91.155.” 91.155 defines basic VFR weather minimums. So, to fully interpret what the AIM is saying, we have to take into account the type of airspace we are in to determine if we can safely and legally operate at pattern altitude at a particular airport.
For example, let’s say we are at KCVB, the Castroville Airport. Pattern altitude there is 1,602 feet, which is 829 AGL. CVB is Class G airspace up to 700 AGL, then Class E above that. Let’s say there is a 700 AGL broken cloud layer. Pattern altitude is 829 AGL, so you won’t be able to get up that high with a broken ceiling. What altitude can you do pattern work at to stay legal?
Class G VFR weather minimums during the day below 1,200 AGL is 1 SM visibility and clear of clouds. So, legally, you could fly at 699 AGL (which at CVB would be 1,472 MSL) while in the pattern and be legal. Safe? Maybe, but probably not if you are skimming the base of the clouds. Is 1300 MSL a safer pattern altitude in this example? Well, that is 527 AGL, so probably not, since towers tend to stick up that high sometimes.
Let’s go back to KSGR and put a 1,000 AGL overcast ceiling there. SGR is Class D airspace and we already determined pattern altitude there was 1,000 MSL for piston singles. VFR visibility and cloud clearance requirements in Class D airspace are 1,000 feet above clouds, 500 feet below clouds, and 2,000 feet horizontally from the clouds with 3 SM visibility. In order to stay 500 feet below the clouds, you would be flying a 582 MSL pattern. Safe? Probably not, though it is legal.
To summarize, don’t take Foreflight’s word for pattern altitude. Cross reference the A/FD (it only takes 15 seconds at the most) to verify. If it’s cloudy, it’s really best to stay on the ground, but if you want to find out your legal pattern altitude with a cloud deck, cross reference 91.155. I don’t recommend flying below pattern altitude because it is there for a reason.
L-3 has jumped into the ADS-B transponder game with their Lynx line of products. Aircraft owners have a myriad of options with the Lynx line, from simply becoming ADS-B compliant with the NGT-1000 ($2,100, with ADS-B out that works with the GTX 327 and GTX 330), or going all in with the NGT-9000 touch screen transponder complete with ADS-B In, a traffic screen and NEXRAD ($6,800).
The NGT 1000/2000/2500 line works with the existing transponder in the airplane (as long as it’s a Garmin GTX 327 or 330). The 2000 gives ADS-B In capability, allowing the pilot to access NEXRAD and traffic, plus has a Wifi source to broadcast all the information to an iPad. The 2500 includes all of that, plus gives the pilot MFD capability as well. An optional control panel is available if the airplane is not equipped with one of the aforementioned Garmin transponders.
The L-3 Lynx NGT-9000 is an actual transponder replacement. It is a touch screen device that has a multitude of ADS-B features that, quite frankly, are really cool on a transponder. The ADS-B traffic is displayed on the unit itself and can also be sent, via the optional Wifi connection, to an iPad on the WingXPro or SkyRadar apps. The optional L-3 NextGen Active Traffic can also be installed to receive traffic callouts (this does not include resolution advisories). Already have SkyWatch? The L-3 Lynx can use the equipment.
The L-3 Lynx NGT-9000 is also capable of displaying NEXRAD as well as METARs, TAFs, NOTAMs, and TFRs and a myriad of other weather products, all on it’s moving map. It seems that L-3 has taken the transponder and turned it into something awesome.

A couple of months ago, I had a life-threatening experience while flying. Thankfully, with my flight training, along with a lot of luck, I am here to talk about it.
One of my many piloting jobs is as a glider tow pilot. For those not familiar with gliding, since a glider doesn’t have an engine, every time a glider pilot goes and flies, it’s a team effort. A powered airplane (anything from a Super Cub to a turbine powered Air Tractor) is attached to the glider via a tow rope, which is about 200 feet long. Once the glider pilot gives the go ahead over the airport’s CTAF, then the tow plane begins it’s takeoff roll, pulling the glider along behind it.
The glider becomes airborne prior to the tow plane, then the tow plane will circle the airport environment till it get’s to the pre-determined altitude to release the glider. Some tows are pattern tows and some are higher (not usually above 3,000 AGL), depending on the request from the glider pilot. Once the altitude is reached, the glider pilot pulls a handle in the glider to release the tow rope, then begins his glide. The rope stays attached to the tail of the tow plane, which in turn descends back down to the runway and lands. The tow plane also has a tow rope release handle in case of emergency.
On this particular tow, the plan was to tow the glider up to 3,000 AGL. Upon reaching 2,500 AGL, the glider pilot called me on the radio and stated that his rear canopy had opened up. I looked over my shoulder and sure enough, the rear canopy was fully opened while he was still in level flight behind me. I asked him if he wanted me to tow him closer to the field, but he didn’t reply.
Now, as an experienced tow pilot, I know a glider canopy popping open should not be an emergency situation. It’s definitely abnormal, but would be similar to a door or window popping open in a powered airplane. Not a big deal. If too much force from the relative wind is applied to the canopy, it would snap off; however, a glider can easily land without a rear canopy.
About 5 seconds after I radioed the pilot (and received no reply), I felt my tail instantaneously lift up into a completely vertical position, which caused my nose to go straight down. The next thing I knew, a whole lot of earth suddenly filled my windscreen and I was in what’s known as a graveyard spiral.
A graveyard spiral (as defined from the Airplane Flying Handbook pg 4-23), “is a descending turn during which airspeed and G-load can increase rapidly….the airplane is flying very tight circles, in a nearly vertical attitude and will be accelerating since it isn’t stalled.” It’s also known as a spiral dive.
Back to the story. At this point, I tried to reach for the glider release handle. Unfortunately, due to the shoulder straps holding me against the seat, plus the g’s, and also the quart of oil and tow bar that flew forward and hit me in the back of the head, I couldn’t reach it. I was semi-upside down at a certain point, which dislodged the oil and tow bar from the floor of the baggage compartment. They sailed over the seat and nearly gave me a concussion.
At this point, 2,500 feet above the ground, I had a choice to either fight for my life at a very low altitude or to sit back and become part of a big explosion.
I decided to fight for my life.
As I was spiraling to the ground, I felt the tow rope snap. Up to this point, I had still been attached to the glider. The rope snapping was a good thing, as my airplane was now under my control, not attached to, and being affected by, a glider (more on that later). I now had a lifeline, no pun intended.
After I felt the rope snap, my instincts and training kicked in. I initiated the spin recovery procedure using the PARE acronym. This task was difficult to do as I had a lot of debris flying from the rear of the plane to the front, blocking my view out of the windshield. There was also debris around my feet, hampering my ability to use the rudder pedals. The spiral finally stopped and I recovered approximately 500 feet above the tree tops. It took my heart a lot longer to stop spinning.
After barely regaining my emotions, I tried to evaluate the condition of the plane. Were all the pieces of the plane still there, was the engine damaged, did my control surfaces still work?
Once I advanced the throttle and saw an increase in my engine RPM, I started an immediate climb to give me altitude to get back to the airport. I had engine power but I wasn’t sure how long it would last if I had damage. Now, what they don’t teach you during spin training is that when this happens unexpectedly, you will become very disorientated. You have just been spiraling unexpectedly and your equilibrium will be out of whack. As I leveled out just over the tree tops, I was too low to visually see any landmarks, nor could I see the airport. Once I was able to climb, I was able to orient myself and figure out where the airport was.
I had to be very careful getting back to the airport and landing without radio communication, since my radio was knocked out with all of the FOD from the baggage area. Thankfully, the landing was uneventful. After I landed, I saw the glider limp in over the trees. The rear canopy was totally gone, while the front canopy and other parts of the glider had suffered major damage. Miraculously, my airplane wasn’t damaged, except for the wire from the radio which came loose during the spiral.
So, how did all this happen, you ask? Well, the glider pilot made 2 huge mistakes. First, in gliding, the moment the glider pilot loses visual sight of the tow plane, you are supposed to release the tow rope. He did not do that and almost killed both of us.
Second, as pilots we are taught to always fly the airplane first. Everything else, no matter what it is, always comes after flying the airplane. As I stated previously, the loose canopy is not an emergency situation, but since the glider pilot did not aviate first and was distracted, it was almost a fatal day for 2 people and 2 airframes.
So, what caused this chain of events? By getting distracted by the open canopy, the glider pilot inadvertently pulled back on the stick while trying to close the canopy. Then, by not releasing the glider from the tow plane, the glider pilot climbed rapidly with an excessive rate of climb while still being attached to me. The rapid climb is what pulled my tail up, causing my nose to drop and put me into the spiral. The tow rope snapping set into motion my recovery, since up till that point, I literally had no control. An extremely high lift wing was attached to my tail, pulling it up, and there was absolutely nothing I could do about it.
We all spend time practicing and demonstrating emergency maneuvers during our flight training and during flight reviews. Many times you might think, I’ll never need to use this stuff. Thankfully, some of the procedures I learned in the past kicked in at a time of need, even though my heart was beating out of my chest.
At some point in every pilot’s career, some type of spin training or Upset Recovery Training would be highly recommended. Then, when things go wrong, remember to always aviate first, then handle all the other things that need to be handled.

When a pilot first glances at the title of this article, the first thought that probably goes through that pilot’s head is, well that’s easy.
And it is, if you are flying a high wing Cessna. On other airplanes, there are a few tricks to checking the stall warning horn. If you get them wrong, you’re liable to get a bill from your maintenance shop for an hour of labor for a problem they couldn’t duplicate.
Cirrus SR22
Let’s start with the Cirrus. On the pre-FIKI Cirrus aircraft, there was a small little hole in the wing that contained a diaphragm. That diaphragm sensed a change in airflow at a certain angle of attack just below the critical angle of attack and set off the stall warning horn. Unfortunately, the only way to check that is to suck on the hole during pre-flight.
I don’t. I verify the hole is clear and that’s about it.
On the FIKI Cirrus aircraft, there is actually a stall warning vane. It looks like a high wing Cessna vane, but if you turn the batteries on and try and get it to come on during your light and pitot heat check, nada.
Here’s the trick, and the checklist doesn’t do a good job of describing this.
Turn on the Avionics Master
Turn on the speaker
Put the flaps to full
Then move the stall warning vane and you’ll hear the horn
The speaker and the Avionics Master are so you can actually hear the horn (if you had the headset on while you were doing this, the speaker would be unnecessary). The flaps have to be full because the pitch attitude for the critical angle of attack is lower with the flaps down, so the horn goes off when at a different angle. You then don’t have to use as much force to push the vane.
Piper PA46
The early -310P Malibus are pretty simple and straight forward. Move the vane, get the horn.
In the -350P, you can’t get the horn to come on by moving the vane. So, Piper put a stall test button that’s hidden underneath the upper left side of the instrument panel. Push that to test the horn. On the G1000 PA46, it is located directly above the PFD. On the Avidyne, it’s below and to the left of the pilot’s yoke.
Testing the stall warning horn is a very important part of pre-flight. A pilot needs to know if the aircraft is close to a stall. The advent of Angle of Attack indicators in small, GA aircraft, have added a greater awareness to the angle of attack during all phases of flight to avoid those stall spins.
If the stall warning horn goes off or the AOA shows yellow, lower that nose immediately.
