WebWhen the aircraft exceeds its critical angle of attack, it will stall—for many GA aircraft, that occurs between 16 and 18 degrees, both in nose-up and nose-down flight attitudes, turns, and during pull-ups (vertical turns). A too-high AOA and subsequent stall can easily happen with the nose down and plenty of airspeed. WebNov 25, 2013 · To thoroughly understand the attack angle for drag and lift force which acts on the propeller blade surface in propeller design, one shall need to be familiar with the standard pitch lines as showed in Fig. 2. Pitch lines is associated with the hydrofoil sectional profile. For these pitch angles measurement it can be taken from the vertical axis.
