For example, Tomahawk Cruise Missile, or Harpoon anti-ship missile. They fly straight and level for the most part of their flight regime. I think if they had a fuselage optimised for level flight then …

I was looking at the Raptor and noticed the white looking tubes underneath the canopy. Do the tubes have a purpose? If so what is the purpose/function of the tubes? Are there any other aircraft with …

The Pipistrel Sinus has detachable wingtips and wing extensions. However, they designed the plane with a wing core span at 39’11”, just barely larger than a standard “40′ door” (which …

The Tupolev Tu-95 has this long and quite substantial appearing projection from it’s nose just under the cockpit windscreen: What is this? I initially though this might be a cannon but being a heavy …

(image source: airliners.net) What are those humps on the rear of the wing? Are they external fuel tanks?

Most airplanes’ trim systems manipulate a tab associated with a primary surface. For example, a pitch trim tab (secondary surface) is attached to the elevators (primary surface) and will change the …

during landing training in a cessna 172, would you rather cut the power to idle at beginning of runway threshold, or idle when you’re close to ground? I keep having problems where I flare too high or …

Greatest hits from previous weeks:
|
|
From take-off performance calculations I remember that the take-off and initial climb was expressed in a number of segments. Each segment had its own performance requirements. I presume they are …

I have pretty bad flying phobia and often wonder what would happen if all the engines on the craft went out at the same time. I initially had the anxiety-ridden thought that the hundreds of thousands …

When looking at an airplane, what are the main external features I should look at if I want to determine if it is an Airbus or a Boeing (shape of the tail, fuselage, winglets, wings, etc.)? Same …

What advantage does a delta wing have over a swept wing with high AR for supersonic flight? And what disadvantage does a delta wing have over a swept wing with high AR for transonic flight? The …

Can you answer these questions?

According to my research I saw that, in order to detect the angular orientation AHRS uses gyro and accelerometer. Only gyro does not work well because of integration drift. Only accelerometer also …

|
There are some neat gliders out there like the Pipistrel Sinus where the wing can be shortened/lengthened considerably by swapping out the outer wing panels. If I wanted to do something similar and …
