1. As altitude increases, the indicated airspeed at which a given airplane stalls in a particular configuration will
Answer (B) is correct. (AC 61-67C) All the performance factors of an airplane are dependent upon air density. As air density decreases, the airplane stalls at a higher true airspeed. However, you cannot detect the effect of high density altitude on your airspeed indicator. Accordingly, an airplane will stall in a particular configuration at the same indicated airspeed regardless of altitude.

2. Limit load factor is the ratio of
Answer (B) is correct. (FAA-H-8083-25B Chap 5) Limit load factors are the highest load factors that can be expected in normal operation under various operational situations. The limit load factor is the ratio of maximum positive or negative load imposed on the aircraft to the gross weight of the aircraft.
