lift

#3. Which of the following statements is correct: 1) To generate a constant lift force, any adjustment in IAS must be accompanied by a change in angle of attack. 2)For a constant lift force, each IAS requires a specific angle of attack. 3) Minimum IAS is determined by CLMAX. 4)The greater the operating weight, the higher the minimum IAS.

• A1,2 and 4
• B4 only
• C2, 3 and 4
• D1,2, 3 and 4

#35. What changes to aircraft control must be made to maintain altitude while the airspeed is being decreased:

• AIncrease the angle of attack to compensate for the decreasing dynamic pressure.
• BMaintain a constant angle of attack until the desired airspeed is reached, then increase the angle of attack.
• CIncrease angle of attack to produce more lift than weight.
• DDecrease the angle of attack to compensate for the decrease in drag.

#19. The adverse effects of ice, snow, or frost on aircraft performance and flight characteristics include decreased lift and:

• AIncreased thrust.
• BA decreased stall speed.
• CAn increased stall speed.
• DAn aircraft will always stall at the same indicated airspeed.
