← Nature & AnimalsWhich consequence occurs when a bird experiences a rapid decrease in air density at high altitude relative to its standard flight envelope?
A)Reduced lift and increased stall speed✓
B)Increased drag and reduced maneuverability
C)Enhanced lift and decreased stall speed
D)Reduced drag and increased maneuverability
💡 Explanation
Reduced air density causes decreased air particle collisions reducing pressure on the wings via Bernoulli's principle, therefore inducing reduced lift rather than increased, and subsequently increase stall speed, because the needed angle of attack will be greater.
