There are two main types of supplementary oxygen devices in light aircraft:
What are the major differences between these two devices? Is one more suitable for specific siutations than another, or is it just a matter of personal preference?
Cannulas are not effective above medium altitudes, and the FAA prohibits their use above 18,000 feet (FAA brochure on Oxygen Equipment, PDF). Because they only place oxygen at your nose, you don't receive oxygen when talking or breathing through your mouth, while a mask covers both nose & mouth. This is, obviously, not great.
Cannulas are also less comfortable than a nice-quality mic/mask, but that's my personal opinion. A lot of pilots do prefer cannulas for comfort at lower altitudes, as they're easier to don and allow you to continue using your normal headset mic boom. For most pilots, especially those flying normally aspirated aircraft types, it's a matter of preference.

In a full motion Level C or D simulator like those used by the airlines and for jet type ratings: How should a pilot log the simulator time in their logbook? I.e. Can you log: Total Time Instru...
I was looking through my virtual radar logs one of the days and found this "glitchy" ADS-B behavior. I am almost 100% sure that this is not due to my antenna or setup since two independent different radars confirmed this weird behavior from FlightRadar24. Also A/C before and after this one did not exhibit this behavior. Does anybody have any thoughts as to what may be happening??? Why... of occurrence is approximately: 3/16/2014 6:09pm CST I have also verified FlightAware is ALSO showing the same weird glitch. See below "yellow" highlighted airplane: Same A/C from FlightRadar24
The alpha vane is an external probe used to measure the angle of attack. I have been trying to understand how exactly it works, but I can't find any clear explanation or simulation. Is the vane static or dynamic i.e. does it rotate along its central axis? Given that it has a significant surface area, I think that it would either: Rotate because of the force/drag exerted by the airflow, and give an angle of attack proportional or equal to its angle of rotation Measure the force being exerted on it via a force sensor embedded in the surface Is either of these correct? In short, how
Looking at the paths of the same flight on two different days, I noticed they flew very different paths. Short Path:1 YAY N184B TOPPS ENE PARCH1 Long Path:1 NIBAX G462 TUMAK UL602 ORSOL UL602... REGHI UN480 ETIKI NATD DOVEY LACKS BERGH L454 OWENZ CAMRN CAMRN4 I asked a similar question in the past. This is what I want to know: What are the reasons which can cause a commercial flight to change its path mid-route? How it is planed and executed? I am sure the captain is the final authority on this, but who else is informed? 1Route Source: FlightAware. P.S.: I could not understand
a simple explanation of the above case. Edit: I am attaching two screen shots of two sets of equations from two sources. Links to the books are included below. Both sources state...I hope this is a relevant place for me to ask a math question regarding aircraft design. I am trying to understand how one would implement a controller to control the pitch angle of an airplane for a small exercise. I understand the control part and its implementation. What I do not grasp is how one acquires the longitudinal equations of motions (which are then used for the control part) which
What should a pilot do to perform a successful emergency water landing, also known as ditching of a big commercial jet? Is there any checklist, or best practices, like "elevate the nose" or "retract ...
I took a couple of pictures of various aircraft and I would like to know which aircraft I photographed. I have no idea, expect that all of them took off from ZRH and should be commercial airliners:
I've noticed that on some airlines (I may have seen it on SAS) the cabin crew had a small touchscreen at the front of the plane which they were using to select recorded audio messages etc, in both their language, and English. Searching the internet, I found out it's called a Flight Attendant Panel — here are some photos I found: So I gather they can control the lighting, and movies; but what else can these panels do? I also found a FAP trainer, which says: This virtual training environment generates a realistic FAP representation including OBRM, CAM and PRAM What
So the answer in my mind is "of course pilots can fly circling approaches at non-towered airports" (seriously, I could swear that I've done it before, but then again I can't think of any specific examples....). That is, until I ran across this little tidbit in the Air Traffic Control Order while researching another question: 4-8-6. CIRCLING APPROACH a. Circling approach instructions may only be given for aircraft landing at airports with operational control towers. So then the question becomes, why do they have circling minimums at non-towered airports?? No tower here. ATC
