What is a notch maneuver?

Answer 1

Oh, dude, a notch maneuver is when an aircraft pilot adjusts their flight path to avoid a collision with terrain or obstacles by flying into a notch or gap in the landscape. It's like playing a real-life game of dodgeball with mountains and trees. So, yeah, it's basically just a fancy way of saying "squeezing through tight spots in the sky."

Answer 2

A notch maneuver is a defensive flying technique used by aircraft pilots to avoid a threat, typically a missile. By rapidly changing the aircraft's heading and altitude, the pilot attempts to force the incoming threat to miss its target and pass harmlessly by. This maneuver is often employed in combat situations to increase the aircraft's chances of survival.

Answer 3

Notch maneuver is when an aircraft being tracked by a pulse Doppler radar (whether ground or air intercept radar from an adversary aircraft) flies perpendicular to the radar to escape detection and tracking. Since Doppler radars use Doppler shift to determine its target's velocity and whether it's flying away or inbound, when the targeted aircraft flies perpendicular relative to the radar, it loses it's Doppler shift, thus, the radar ignores it thinking that it's a stationary target such as mountains and etc.
