1.	An aircraft is cruising with cruise speed of 250m/s. All of the sudden aircraft experiences in a gust with velocity of 10m/s. determine the change in angle of attack due to this upward gust.(a) ∼2.3°(b) ∼6°(c) ∼5.6°(d) 9°This question was addressed to me by my school teacher while I was bunking the class.The query is from Air Loads topic in chapter Structures and Loads of Aircraft Design
Answer» RIGHT choice is (a) ∼2.3° Best explanation: Change in AOA = ARCTAN (GUST velocity / CRUISE speed) = arctan (10/250) = arctan 0.04 = 2.29 ∼ 2.3 deg.
