ADX ADX Aircraft Performance and Weight Balance 3

Question 1

What is 'dry operating weight' (DOW) in airline weight terminology?

Accepted Answer

Aircraft weight with standard crew and equipment but without passengers, cargo, or any fuel

Answer

Aircraft weight measured with all fuel tanks completely drained

Answer

Aircraft weight calculated after removing all passenger seats

Answer

Aircraft weight recorded immediately after the fuel burn of the previous leg

Question 2

How does an uphill runway slope affect takeoff performance?

Accepted Answer

It increases the required takeoff distance because gravity opposes acceleration

Answer

It decreases the required takeoff distance by assisting initial roll speed

Answer

Runway gradient has no effect and is ignored in performance calculations

Answer

Only downhill slopes are factored into certified performance data

Question 3

What is 'accelerate-stop distance' used for in dispatch planning?

Accepted Answer

The total runway needed to reach V1 and then bring the aircraft to a full stop if takeoff is rejected

Answer

The runway length consumed while decelerating from touchdown speed to taxi speed

Answer

The minimum runway length at which the aircraft can reach cruise airspeed

Answer

The distance measured from the terminal gate to the runway threshold

Question 4

What does 'balanced field length' mean in aircraft dispatch performance?

Accepted Answer

The runway length at which accelerate-stop distance equals accelerate-go distance past an obstacle

Answer

A runway constructed with identical uphill and downhill gradient sections

Answer

A runway designated equally for arrivals and departures by ATC

Answer

The minimum certificated runway length applicable to all aircraft types

Question 5

What is V1 speed and why is it critical for the dispatcher?

Accepted Answer

The takeoff decision speed at or below which a rejected takeoff must be initiated

Answer

The minimum speed at which the aircraft can sustain controlled flight

Answer

The maximum speed permitted with the landing gear in the extended position

Answer

The target cruise airspeed published in the flight planning documents

Question 6

What does obstacle clearance analysis ensure in departure performance planning?

Accepted Answer

That the aircraft can climb above all terrain and obstacles in the departure path even with one engine inoperative

Answer

That ground crews have cleared all equipment from the runway environment

Answer

That adequate vertical separation exists between aircraft at cruise altitude

Answer

That airport vehicles avoid the taxiway path during pushback
