Aircraft Fundamentals

Absolute Humidity

• Percent of water vapor

• Fractional part of the amount of water vapor

• Actual amount of water vapor

• Assumption of the amount of water vapor

What condition would cause less lift?

• Origin of the sound

Which of the following conditions will cause the true landing speed of aircraft to be the greatest?

• Low Temp : Low Humidity

• High Temp : Low Humidity

• High Temp : High Humidity

• Low Temp : High Humidity

As altitude increases

• Pressure Increases

• Density stays the same

• Density decreases

• No change in pressure or density

What is referred to as the temperature which humid air is cooled to become saturated?

• Dew Point

• Relative Humidity

• Temperature Logic

How does an aircraft wing produce lift?

• Low pressure above the wing : High pressure below the wing

• High Pressure above the wing : Low Pressure below the wing

• Negative Air at the wing root

• Turbulent air at the wing root

Newtons 3rd Law?

• Law of Inertia

• Gravity

• For every action there is an equal and opposite reaction

• Law of Metaphysical Conceit

Aspect ratio?

• Wingspan to the wing root

• Square of the chord to the wingspan

• Wingspan to the mean chord

• Engine location to the wingtip
