Which Airspeed?
One of the most important bits of information pilots can glean from our instrument panels is airspeed. Its used on takeoff to gauge when to apply backpressure for liftoff, its used when landing to ensure were neither too slow or too fast, and we use it in cruise to help verify performance (and establish bragging rights). Depending on the airplane and the days mission, we may also use it to ensure were at or below an appropriate speed before penetrating turbulence or conducting various maneuvers.
