Flight Performance & Planning

Question 1

What does a normal category on a Mass & Balance Chart imply?

Answer 1

Normal flying. No Spinning or aerobatic manoeuvres an bank angle restricted to 60 degrees.

Question 2

What are Vlo, Vle, Vfe and Vno?

Answer 2

Vlo - Max Speed for gear operation
Vle - Max speed with gear extended
Vfe - Max speed for full flap
Vno - Max structural smooth air cruising speed

Question 2

What is denser humid air or dry air?

Answer 2

Dry Air. Since water vapour is less dense than air.

Question 3

What are the two steps involved in calculating Density Altitude?

Answer 3

Correct current altitude for differences to ISA Pressure to gain ‘Pressure Altitude’

Correct ‘Pressure Altitude’ for differences to ISA Temperature

Then you have density altitude.

Question 4

Describe best rate of climb

Answer 4

Vy
The best altitude gained per unit of time

Question 5

Describe best angle of climb

Answer 5

Vx
The highest angle of climb. Enabling highest altitude in shortest distance

Question 6

What happens to performance if the CoG is forward?

Answer 6

Performance is reduced

A forward CofG requires more down-force from the tail plane ot raise the nose, adding weight to the aircraft. The high AoA required also increases drag.

Question 7

Define Vmc

Answer 7

The minimum control speed for twin engine aircraft

Question 8

Define Vref

Answer 8

The reference landing speed that is used at the 50ft obstacle barrier height

Question 9

Define Vat

Answer 9

Approach Threshold Speed, equivalent to the stall speed x 1.3

Question 10

For Private Flying what are the final fuel reserves?

Answer 10

The amount of fuel you MUST have remaining in the tank after landing is 30 minutes (Day) or 45 minutes (night/IFR)

Question 11

What is private flying best practice for fuel?

Answer 11

Route (Cruise)
5% Route Contingency
Diversion
Final Reserve (30/45)
Takeoff Climb, Descent, Land Taxi (Equiv of 15 minutes of cruise fuel)
