My bird keeps printing pictures of paper airplanes. He leaves them all over the house, and then will look at them when he eats. Why does he do this? Read more

How is it regulated? Who do they contact before they liftoff? How do they know where other airplanes are? Do they have radar on their screens?
My guess: they have to use an airport which has air traffic controllers? Read more

This a thermodynamic question from a chapter on specific heats, entropy & adaibatic-processes: “Commerical jet aircraft fly at cruising altitudes between 30,000 & 40,000 ft. Yet such aircraft carry heat exchangers to cool cabin air while flying at these altitudes. (a) Estimate the air temperature at which jet aircraft fly. (b) Explain why it is necessary to cool cabin air at cruising altitudes. Hint: The ratio of the heat capacities of air at constant pressure and volume is about 1.4.” I alrealy have the answer to (a). It’s 181 Kelvins. I need help with (b). Even if you could just give me a verbal answer for why airplanes have to cool their cabins and hence pressurize them would be helpful. Thanks. Read more

I just realized airplanes have sort of a smoke exhausting pipe below the tail’s vertical flap… What kind of engine do they have inside to produce that much smoke and what’s its purpose??
Thanks!! Read more

Ok im doing a report on airplanes from the small ones to the airliner jets and was wondering what exactly it means when a plane stalls. Also are there different type of stalls, and do pilots stall on purpose? And finally can you recover from a stall once it happens? Read more

It says 10-4, but if the airplanes dont start for a couple hours b/c of the boats, I would like to wait to make it down there. Does anyone know what time the airplanes start?
Thanks! Read more

We took in a 120 lb lab mix last November. Since we are spending more time outside this summer, I noticed that he barks at airplanes. When he’d bark in the house at “virtually” nothing, I have now realized it is the airplanes flying overhead. (We are four miles from a small city airport)
Aside from moving, how can I get him to stop barking at them?
Telling him “no” just isn’t enough to get his attention. Read more
