How can you calculate the Operating Mass?

OM = DOM + crew and fuel

Why do aircraft have leading edge devices?

Why do aircraft have leading edge devices?

There are 2 types of leading edge devices:

-Slats. Slats are movable surfaces on the leading edge of the wing which when deployed, allow the wing to operate at a higher angle of attack, by delaying separation in the wing upper surface.

-Leading edge flaps (Krueger). Leading edge flaps are hinged on the leading edge of the wing and extend forward and down when deployed. they provide similar benefits as trailing edge flaps, by increasing wing surface area and camber.

What is an NDB?

What is an NDB?

Non Directional Beacon, a medium range radio navigation aid that sends out a signal in all directions for an aircraft to home to.

How does an altimeter work and which errors can an altimeter experience?

How does an altimeter work and which errors can an altimeter experience?

When an aircraft climbs, the static pressure in the instrument case decreases, which allows the enclosed capsule to expand.

This in turn moves the needle on the instrument to indicate a corresponding altitude.

During descent, the opposite function applies.

Altimeter errors can originate and vary from:

Instrument Pressure Time-lag Barometric Density Temperature Blocked static port

If in a go-around, which take-off stages will still apply?

If in a go-around, which take-off stages will still apply?

None. The go around procedure is distinct from the take off procedure. You will still have an acceleration altitude, but you will not have a screen height, V1, Vr, V2, flap retraction altitude, etc.

What are the benefits of a free turbine?

What are the benefits of a free turbine?

A free turbine is a turbine that is not directly connected to the compressor. This allows the compressor to rotate at a different speed than the turbine. Since the turbine speed is coupled with the propeller, this allows for the propeller to be maintained at a constant ideal speed.

Another advantage is that free turbine engines can be designed to be more compact than their single shaft counterparts

What do airplanes have to guard against reaching Mcrit?

What do airplanes have to guard against reaching Mcrit?

Barber pole on the ASI, flying at a Mach number at altitude and audible warnings.

What are the disadvantages of a swept wing?

What are the disadvantages of a swept wing?

Swept wings have:

  • Poor lift qualities

  • Higher stall speeds

  • Speed instability at low speeds

  • A wing-tip stalling tendency

What do high lift devices do?

What do high lift devices do?

High lift devices increase the lift produced by a wing, allowing the aircraft to operate at lower speed ranges usually for take off and landing.

You have lost both alternators, how long would the battery last and what would you do?

You have lost both alternators, how long would the battery last and what would you do?

30 minutes, I would land as soon as possible.
