CPL Flight Performance and Planning 3

Question 1

What is the significance of V1 (takeoff decision speed) during a multi-engine takeoff?

Accepted Answer

The maximum speed at which the pilot can abort the takeoff and stop within the available runway

Answer

V1 is the critical engine failure recognition speed; at or above V1, the pilot must continue the takeoff because stopping within the remaining runway is no longer assured.

Question 2

For FAR Part 135 operations, what is the IFR alternate airport fuel requirement?

Accepted Answer

Fuel to destination plus fuel to alternate plus 45 minutes at cruise

Answer

FAR 135.209 requires fuel to fly to the destination, then to the alternate, plus 45 minutes of cruise flight at normal fuel consumption.

Question 3

What is the 'accelerate-stop distance' (ASD)?

Accepted Answer

The total distance needed to accelerate to V1, experience an engine failure, and stop completely

Answer

Accelerate-stop distance is the total runway required to accelerate to V1, recognize an engine failure, and brake to a full stop.

Question 4

A pilot is planning a flight at 10,000 ft MSL and the outside air temperature is +10°C. Standard temperature at 10,000 ft is -5°C. What is the density altitude?

Accepted Answer

Approximately 12,700 ft

Answer

With OAT 15°C above standard, density altitude is approximately 10,000 + (15 × 120) = ~11,800–12,700 ft depending on correction formula used.

Question 5

What is meant by 'balanced field length'?

Accepted Answer

The condition where accelerate-stop distance equals accelerate-go distance

Answer

Balanced field length is achieved when the accelerate-stop distance equals the takeoff distance following an engine failure at V1, optimizing use of the available runway.
