Illusions of Lift
A pilot can create an indication of lift on certain uncompensated instruments by entering a climb by pulling back on the stick (hence “stick thermal”). This is not true lift, in that the energy to climb is being converted from decreasing airspeed, rather than being extracted from rising air. Inexperienced pilots can mistake this for actual lift.
