Erasure of technically unsound material
Today I erased significant amounts of text. This text was unsourced and technically unsound.
The article had evolved to acknowledge that reduced air density causes higher True Airspeeds and to imply that higher True Airspeeds, especially the True Airspeed at the stall, constitute a reduction in performance. This is untrue.
Most aircraft do not have an airspeed indicator that indicates True Airspeed. Consequently the pilot is oblivious of the True Airspeed, especially as reducing air density has no discernible effect on aircraft handling qualities.
The deterioration of aircraft performance in hot and high conditions is due almost entirely to the reduction in thrust from the power plant. It is almost unrelated to the increase in True Airspeed relative to Indicated Airspeed. Dolphin (t) 01:13, 22 June 2017 (UTC)
