Which consequence occurs when a bird experiences a rapid decrease in air density at high altitude relative to its standard flight envelope?

💡 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.
