Is there any website or data-sheet that I can find drag of airplane for cruise conditions. $C_D$ vs $C_L$ graph is also acceptable. To be more specific I am searching drag values of A320 in cruise ...

A glider gets the power it needs to fly from the decrease of gravitational potential energy associated to the descent. My question is: for the same weight $W$, airspeed $V$, and a prop efficiency of ...

One of the most concerning factor in flight safety is the possibility of the plane erupting into fire due to a fuel spill and a spark. Is it possible---or have researchers ever worked on---to power an ...

Is there a tank priority sequence for using the fuel tanks, or does the pilot decide?

In most charts there is the letter D next to the VOR freq. What does this mean? I assume the H and L in brackets in other charts mean high and low VORs (correct me if im wrong). But what does the D ...

For example left elevator angle = +30 deg, right elevator angle = -30 deg. Would these settings be able to induce a rolling moment on the aircraft? What would happen with the pitch?

Nearly all modern transport aircraft are designed with a plug-system fuselage, allowing longer and shorter variants to be built by adding or removing plugs. In addition, the plug system simplifies ...

Someone has stolen an empty airplane from Seattle Airport and crashed it down after performing some loopings. I am wondering how this was possible. (Source)

A lot of times I see small tube like streams of visible moisture training from the middle of an airliners wing. I assume this is induced drag created by wingtip vortices, when the aircraft is heavy, ...

The Daimler-Benz DB 605 was an inverted V12. The compression ratio of the 2 banks varied slightly. Why did the designers do this? Compression ratio: 1:7.3 right bank, 1:7.5 left bank (museomotori....

Are there any airports with approaches and/or departures that require pilots to fly under an obstruction at some point (thus meaning that, for at least a short segment of the approach or departure, ...

I’ve been studying Pilots Handbook of Aeronautical Knowledge FAA-H-8083-25B and on p 5-17 they talk about thrust line and stability. Can someone explain why the moment changes when thrust is applied? ...
