Assertion: airfoil's angle | /r/HasProperty | reached
Facets:
Source sentences:
text: When the critical angle is reached, the air ceases to flow smoothly over the top surface of the airfoil and begins to burble or eddy.
text: The graph shows that the greatest amount of lift is produced as the critical angle of attack is reached (which in early-20th century aviation was called the "burble point").
text: As speed reduces, angle of attack has to increase to keep lift constant until the critical angle is reached.
text: Some aircraft are equipped with a built-in flight computer that automatically prevents the aircraft from increasing the angle of attack any further when a maximum angle of attack is reached, regardless of pilot input.
