Seeing a recently uploaded picture of a smoky landing about which the photographer insisted was a hard landing, I began to wonder whether a 'hard landing' really would produce more smoke. I don't think the faster application of weight on the undercarriage and tires really would make that much of a d...Jump to post
Well, I do know that even in WWII the Me-109 had linkages from the control stick to a set of leading-edge flaps (slats) that would extend directly as he pulled the stick back -- their extension was propotional to the amount of upward elevator deflection. Though I bet it must have caused some drag, I...Jump to post
JohnM is correct, the Du rounds do contain a certain amount of radioactive material. As I believe, after the conflict in the Balkan region, Italian 'cleanup crews' found much soil to have been exposed to radiation that had come from depleted uranium rounds, used not only by A-10's but other aircraft...Jump to post
Seems to me a simple idea could be to use bleed air on a impeller on the wheels. That could probably get the wheels going significantly fast, without a chair or other complicated mechanical device. Just a thought.
As far as I know, and I may be way off, much of the smoke at startup is engine oil that has collected in the engine cowlings being burned. Maybe the L-1011's didn't have well-sealed oil lines or they were at a low pressure... So I'm not sure why it's there, but I'm pretty sure the smoke is from engi...Jump to post
Looking at the BA flight paths, it shows that the aircraft use radio navigation aids to chart a course. Being but a simulator pilot, I had thought that GPS is used more often nowadays in making more efficient courses for aircraft. Is it used more often that not or are radio navs used? Also, does the...Jump to post
Hey, watch it Iainhol! Not only are they some of the most elegant things around, they can do stuff that those bulky fixed wings can only dream of! I'd take a chopper over a fixed wing any day... By the way, does anyone know of anything similar in the New York area?
Being just a lowly flightsimmer, I always figured spoilers were only for slowdown on rollout. Then, reading more about aerodynamics and spoilerons and the such, I learned that, true to their name, they spoil the lift over a wing. So, what are their true purposes? In flight, is the main purpose to de...Jump to post
I was browsing photos in the database and came across a slew of photos from Airtours International, at which point I did a specific search for the airline and was surprised at what a presence it had. How long has it been around? What kind of fleet does it have, like what does it hav the most of? Whe...Jump to post
As Delta-flyer said, the photograpers that take the pictures you see on A.net cannot get too close to the aircraft, so they use very high-power telephoto lenses. These lenses very much compress everything in a picture, so the curvature is much flatter than it looks.
In the opinion of the engineers and mechs and all others in the forum, what do you think is the single part of an a/c that is stressed the most? To me it seems to be the landing gear, because of all the restrictions put on them and the many subleties of them. But I may be proven wrong by all of you ...Jump to post

In the Boeing website galleries, I found pictures of both the KC-10 and the KC-135 refueling other aircraft of the same type. I'm sure they're other tankers because the boom can be seen on each aircraft. Anyway, why do tankers need refueling capability? I imagine they have a pretty large fuel capaci...Jump to post
On air-refueling aircraft, there are usually words I can't distinguish on the little wings the boomer uses to fly the probe to the refueling recepticle. Do these words associate the aircraft with their home base, like the 2 letter codes on fighter aircraft vertical stabs, or do they have some kind o...Jump to post
Not being a pilot, obviously, I cannot say if the approach is difficult or not. But the approach is similar in that it is not straight in - There is a large turn before aligning with the runway and flaring for touchdown. It's interesting to watch, actually, and see the aircraft bank and yaw so close...Jump to post
At major airports, do most airlines hire contracted services companies for work on the planes, i.e. pushing, baggage, fuel, waste etc. or do they do it themselves? What about smaller airports? The reason I ask is I would absolutely love any job at an airport... I'm in the JFK-LGA area and was wonder...Jump to post
That sure is wierd, ExPanAmer. I'm not sure, but from a scientific point of view, the number of people in all the flight crews isn't quite a large enough sample size for any speculation for that... Also, with some still flying, I don't think that enough time has elapsed to really look at aspects lik...Jump to post
When looking at the Air Force specs page for the C-5, there are two maximum takeoff weights - 769,000 pounds (peacetime), 840,000 pounds (wartime). Why can more be carried in wartime? Does it involve running engines over n1 or something along those lines or do you just flick a switch to increase pre...Jump to post
I agree with Flight152: A gallon of white paint doesn't weigh any real amount more or less than a gallon of black paint. The ingredients are the same - a base, a colloid (I think), and a pigment. I dont see why one would weigh more than another.
I think it's just because it's a common mathematical symbol - just as X,Y, and Z are, N is common for substituting things algebraically. Since the readings are just percentages, N1 is shorter than writing "Fan, low pressure compressor and low pressure turbine speed". I hope that makes sense.
Funny how everything is perhaps with the A380... Sure they're big, but what else do we know about them? Why would they have a lot of hours eventually put on them? It seems to me that if you want a bigger airliner, it's to fly more pax, and so it has less flights on it.
