Can doppler radar be used to detect stealth aircraft by focusing on the characteristic flow field instead of the aircraft itself?

To a limited extent, yes, it's possible to detect the air disturbances left by aircraft. This NASA article studies the radar reflectivity of vortex wakes exhaustively. It's being proposed as a safety ...

Why do you land a fighter jet with AOA Units?

We may anticipate that most fighter planes are not staticly stable. When an aircraft is staticly stable, airspeed and angle of attack are set by elevator trim. While on a glide path, the aircraft ...

Why do you land a fighter jet with AOA Units?

While I don't disagree with the other answers, another reason is that AoA is more difficult to measure and is only useful for some parts of the flight (not useful in cruise, for example). So, most GA ...

Why do you land a fighter jet with AOA Units?

Because AOA is the metric that governs all airfoil aerodynamics. And airline pilots also use AOA, indirectly. They determine (calculate) their landing speeds based on their configuration, (flap/slats ...

Why do you land a fighter jet with AOA Units?

Angle of attack is the most convenient metric of the performance of the wing. One can safely assume the wing will for example always stall at the same AoA regardless of weight or speed. Flying ...
