What performance category was your last aircraft? How are airplanes classified?

Note: this question was asked to a candidate with previous Seneca experience, make sure to be able to answer this question for your previous aircraft type.

Seneca is class A.

Aircraft are classified according to their Vat.

What is the range of a VOR at 32000ft?

What is the range of a VOR at 32000ft?

Range = 1.23(√H1 + √H2)

= 1.23 * √32000

= 220 nm

What is the purpose of a locator?

What is the purpose of a locator?

To notify the crew of the aircraft of a particular position on the IAP.

Locators have been largely replaced with Distance Measuring Equipment (DME), but they can sometimes be found associated with Outer or Middle Markers where they are referred to as Locator Outer Marker (LOM) or Locator Middle Marker (LMM).

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

Approach category speeds are defined by which formula?

Approach category speeds are defined by which formula?

This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.

The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.

What are the advantages of fuel injection vs a carburetor?

What are the advantages of fuel injection vs a carburetor?

Fuel injection provides:

  • Fuel free from vaporization ice

  • Better economy through metered delivery

  • More responsive and efficient engine

  • Less maintenance

How does a jet engine/gas turbine work?

How does a jet engine/gas turbine work?

Forward motion forces air into the intake which is a convergent duct where it is compressed (causing a temperature rise).

Fuel is added and combustion takes place increasing the volume. The expanding gasses accelerate to the atmosphere through the exhaust duct nozzle producing a propulsive jet.

What is a moment arm?

What is a moment arm?

The distance from the datum to the point at which the weight of a component acts.

What does the abbreviation MSA mean?

What does the abbreviation MSA mean?

Minimum Safe Altitude.

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.
