Recently, I did my TBM and Meridian recurrent training with Joe Casey of Casey Aviation. I always like being challenged my more seasoned instructors than me because I always get to learn something. When I learn something, it makes me a better instructor and allows me to give better instruction to my customers. Plus, there is still a bunch that I don’t know!
Joe has a podcast titled The Malibu Guru (because he really is the Malibu guru!). During our training, we did a podcast together and he interviewed me. I get to tell about Texas Top Aviation and some exciting things coming up this summer (hint: the biggest exciting thing is called The Aviator’s Academy). Before I give too much away, take a listen to the podcast.
I got a call today from a friend asking me about oxygen requirements. That got my brain pondering about the different items the FAA would like all pilots to know. I did a little refreshing and found several other tidbits directly from the FAA that I thought worth sharing. No matter what you’re flying, I think these apply to all of us.
First off, what are our general oxygen requirements? If you jump on over to the FAR’s and take a look at 91.211 you’ll see:
1. At cabin pressure altitudes above 12,500ft MSL to 14,000ft MSL, pilots
required to use oxygen unless the segment is less than 30 minutes of flight.
2. At cabin pressure altitudes above 14,000ft MSL, the crew is required to use
oxygen.
3. At cabin pressure altitudes above 15,000ft MSL, each occupant must be
provided the use of oxygen. This doesn’t necessarily mean they have to use it.
Things get a little more in depth when you get to pressurized aircraft.
These requirements are also listed in 91.211:
1. If you’re flying above Flight Level 250, a 10 minute supply of oxygen is
required for each person onboard.
2. If you’re flying above Flight Level 350-410, and one pilot leaves their seat, the other pilot will be required to wear an oxygen mask, unless both seats are equipped with quick-donning oxygen masks.
There are three basic components to any oxygen system in an aircraft: the storage system, the delivery system, and the mask or cannula. First, there are several types of storage systems.
Gaseous aviators breathing oxygen is the first. This is the standard green tank that everyone is familiar with. There are two types of tanks. Either the high- pressure with 1800-2200 psi or the low pressure tank with 400-450 psi. The major issue with these and General Aviation aircraft is weight. Some of these tanks can get bulky and heavy and therefore don’t work for everyone.
Liquid aviators breathing oxygen or LOX is another form of storage. The major advantage of LOX is that it has a 900 to 1 expansion ratio, meaning that 1 liter of liquid oxygen can be expanded into 900 gaseous liters of Aviators Breathing Oxygen. The disadvantages of LOX are they are extremely volatile and have to be stored at -197F. If it comes in contact with exposed skin, severe frost bite can occur.
Sodium chlorate candles or oxygen generators have a weight advantage like LOX. They’re essentially a canister that when activated mix sodium chloride and iron powder and produce oxygen. They general have a 600 to 1 expansion ratio, which goes back to the weight savings. However, once these are started they are very hard to stop. Another disadvantage is these devices produce a fair amount of heat, so proper precautions need to be taken.
Next are the delivery systems. The main systems are Continuous Flow, Diluter Demand, and Pressure Demand. Continuous Flow, is exactly as it sounds. The oxygen is allowed to flow continuously from the tank to the user. The benefits of continuous flow are you don’t need a complicated mask or regulator. The downside to this system is since it continuously pumps oxygen, you’re wasting oxygen when you exhale. Most of continuous flow systems are used on aircraft that generally fly below 28,000 feet.
Diluter Demand was designed to fix the negative of the Continuous Flow systems. Diluter Demand only sends oxygen to the user when the user inhales. The system also allows cabin air to be introduced in, sending the perfect mixture of oxygen to the user when needed. These systems are very efficient and generally tend to be used up to 40,000 feet.
Pressure Demand is designed to essentially “over inflate” the users lungs. This will basically pressurize the the users lugs and allow the user to fly above 40,000 feet. This is needed at flights above FL400 because 100% oxygen without positive pressure will not suffice.
The final portion of the oxygen system is the mask or cannula. Nasal cannulas generally are more comfortable and are regulated to 18,000 feet service altitude. Masks come in a couple different variants. From re-breathers to quick-donning, most masks accomplish the same task with a few small differences. Quick-donning must be able to be put on within five seconds and are rated up to FL400.
Since that was a lot of information, what does all of it mean to you? Most fair weather flyers will never run into any of this. However, the high performance owner/operator will run into oxygen use situations a fair amount. Taking the family up to Colorado on a ski trip, jumping up to 12,500 feet to get above some weather, or flying above 5,000 feet at night on a long xc are all situations where you may want to have oxygen on board.
If you are planning on doing any of this type of flying or are currently doing these types of flights, training is a must. If you’ve never been in an altitude chamber, I would highly recommend it. In college, I went with a group to Oklahoma City to the FAA’s headquarters where they hold a class on Hypoxia and High Altitude flying. It’s very informative to be in the chamber as it simulates being oxygen deprived. You get to see how you’ll react and what kind of symptoms you’ll have when in a loss of oxygen situation. Each person has different symptoms, so it’s important to see how you will react.
It’s also good to fly with an experienced instructor. Finding an instructor who will allow you to learn in a safe environment is worth its weight in gold.

Only now did I begin to realize the severity of the situation. The deer had completely broken the left main gear off of the airplane. Obviously, landing in this condition would not be ideal. Landing without a nose wheel is one thing, but landing without one of the mains would be a very dangerous and undesirable proposition.
The company’s maintenance guys arrived on the scene while I executed a few more low passes so that they could take a look. We all came to the same conclusion that the best situation for landing would be to retract the other two wheels so I could land on the belly. Unfortunately, the landing gear wouldn’t retract. Cranking the emergency gear handle didn’t work either as it is not designed to bring the wheels up, only to put them down.
I flew circles around the airport for a while as different options were all discussed. I owe a lot to the guys on the ground who were digging through the manuals coming up with solutions. Eventually, it was decided that I would try cranking the gear up by hand, even though the checklist in the airplane said that it could only be used to lower the gear. Even if we damaged the hand cranking mechanism, it would be worthwhile…plus, I’d already torn off the left main entirely, surely a little damage to the retraction mechanism wouldn’t be the end of the world!
Following the checklist, I pulled the CB for the gear motor and started cranking. To my great relief, the “in transit” light illuminated and the three green indication went away. It was difficult work to crank the gear up manually. The handle is in a very poor location in Barons and Bonanzas, plus I was working against gravity. It is also possible that there was some debris from the missing wheel causing friction or binding. While I was cranking, the rescue crews were being coordinated while extra vehicles and people had been called in from the city for support.
After some time had passed, enough to get a slightly sore arm from cranking, the lights indicated that the gear was up and locked. I lined up for one more pass hoping to verify that the landing gear was up and the landing gear doors were closed. After the final go ahead from everyone on the ground, all that was left was the landing.
I had been doing my best to keep the passengers informed of what was happening throughout the whole flight, but I felt bad for them as the news changed from the beginning of the flight: “precautionary landing” was quite different than the briefing I ended up giving them before we landed. I informed them that I was going to be “… killing the engines and landing with the gear up….” They did an impressive job of staying calm and being responsive. Before we landed, I made sure that they were all briefed on what to expect, how to unbuckle, and how to evacuate from the airplane. It is difficult to convince someone that everything is going to be fine when there are hordes of emergency vehicles (including ambulances) waiting next to the runway in anticipation of your landing.
Shortly before landing, I went through my flows and callouts, then verified by use of the checklist to ensure I hadn’t missed anything. I distinctly remember sitting in the airplane preparing for the landing, all the while being in complete disbelief that this was a real situation. I never imagined that I could be flying an airplane that was missing a wheel strut. Previously, my assumption had been that if there was an event serious enough to shear off one of my mains, the airplane wouldn’t continue flying. It all seemed like a bad dream.
I elected to use runway 26 since it was the longest. I wanted to be able to carry extra speed in order to give myself extra time between pulling the mixtures and landing so that I could feather the props and turn the fuel shut off valves to the off position (never thought I’d have to do that!) without being rushed. As I made my final approach with the engines shut off, I went through my final memory items and couldn’t help but laugh about just how backwards everything was from normal arrival procedure. GUMPS: Gas- Off (normally on the fullest tank), Under carriage- Up (Definitely not normal), Mixtures- Idle cut off (I normally save this for when I’m parked on the ramp), Props- Feathered (Again, never thought I’d have to do that in real life), Seatbelts- On (the only one that stayed the same!).

I’ve had several remarks about how quiet the airplane must have been during the final un-powered glide to the runway, and while that is absolutely true, I must confess that I never noticed. I was so focused on the task at hand that the silence in the airplane simply wasn’t something that stuck out to me. What did make an impression on me, however, was the acceleration the airplane experienced when the props were feathered. I’ve heard it preached many times the importance of feathering the propeller on a dead engine, but never truly appreciated the importance of it until I did it myself. I remember the airplane accelerating noticeably as though I had hit a boost button which was hidden somewhere in the cockpit for just such an occasion.
Although I didn’t notice the lack of noise upon killing the engines, the sickening, deafening noise which was produced during the touchdown and deceleration is something which I will never forget. Another thing that surprised me was the smoke which filled the cockpit and cabin as we slowed down. This was produced by the friction between the belly and the runway, although nothing was burning.
I don’t know how long the airplane actually slid for after touching down, but it felt like an eternity. However, when the noise subsided and the motion stopped everything returned to real time. I unfastened my seat belt, opened the door and climbed out onto the wing. I helped the passengers evacuate and we retreated to a safe distance on the side of the runway while the firefighters rushed in to do their job.
It was 8:35 am. So, from the time we took off to the time we landed was almost exactly an hour and a half. Not surprisingly, the passengers elected not to continue on to Pittsburgh and instead accepted a ride home in a car. The rest of my day was a blur of paperwork, reports, and phone calls.

I’m a big fan of having my Foreflight map always match up exactly with the way I am flying. Having a Flight Stream in the airplane helps a lot with that as it always prompts me to load the new flight plan from the GPS into my Foreflight map. When I load an approach in the GPS flight plan, Foreflight will put it into my Foreflight flight plan via the Flight Stream.
The problem I run into on Foreflight is when there is a published hold at the Initial Approach Fix (IAF), but ATC has told me to fly the straight in approach and skip the hold. Up until recently, I didn’t think there was a way to set up a straight in approach on Foreflight, so I just settled for the hold staying on there.
Not anymore! There is a simple trick that I discovered that allows you to remove the hold from the Foreflight flight plan. Here’s how to do it.
The first step is still to load the approach into your Foreflight flight plan on the Map page. In this scenario, we are flying from KAQO, the Llano Airport, to KHYI, the San Marcos Airport. Austin Approach has told us to expect the straight in RNAV 17 KHYI via PUKIY. So, on Foreflight, we have KAQO and KHYI in our flight plan. Then, I tap the Procedures button on the upper right hand corner of the screen. I then tap Approach, then RNAV 17 KHYI. Then I select my transition.
The options given are either PUKIY with the hold, seen below;
Or Vectors to Final, which lines me up inside of PUKIY. Neither of these are what I want.
But, to get this to work, I select PUKIY, then tap add to route. Now we have our approach loaded into our flight plan.
The RNAV 17 is now in the Foreflight flight plan, but the hold is displayed at PUKIY. To remove the hold, the first step is to tap the approach in green and a menu pops up.
The 7th option down is “Remove Hold in lieu of PT.” Eureka! Tap that, then the approach is displayed without the hold. Houston, we have success! It even says “NoPT” in the flight plan.
You have finally decided it’s time to make an aircraft purchase. You’ve got your private pilot certificate with an instrument rating.
You’ve been flying for 3 years, mainly renting the Piper Arrow at the local flight school. You’ve had some frustrations at times with scheduling, since the Arrow is also used for training at the flight school. The airplane isn’t very well taken care of, is kind of old, and breaks a lot.
After several weekends of trying to book the airplane to take a weekend trip to the family cabin, your frustration finally boils over. It’s time to make an aircraft purchase.
Time for Trade-A-Plane?
Here’s a better question: Have you bought an airplane before? Do you know the process? Do you know what to look for in maintenance records? Do you know what ADs are required? Is the airplane priced higher than it’s valued?
