Attempts to increase the angle of attack at higher airspeeds can cause a high speed stall or may merely cause the aircraft to climb.
The wing will ordinarily stall at a lower angle of attack, and thus a higher airspeed, when contaminated with ice.
"There's a gusty wind, so come in at a slightly higher airspeed," Jack reminded his pupil.
At some higher airspeed the effect will disappear.
More practical research in aerodynamics tends to focus on smoother surfaces and higher airspeeds.
My solution to this problem during early circuits was deliberately to make a steep slipping turn into wind to ensure a high airspeed (Fig. 5.14).
They asked for an escape system that forcibly ejected the pilot from an aircraft and was powerful enough to clear the tail surfaces at high airspeeds.
To provide some context, this is over 6,000 times faster than the highest airspeed ever achieved by a manned aircraft.
An air speed record is the highest airspeed attained by an aircraft of a particular class.
Simply pointing the nose downwards only converts altitude into a higher airspeed with a minimal initial reduction in total energy.
