# Aircraft Performance Questions and Answers – Fixed-Wing Aircraft – Operational Performance

«
»

This set of Aircraft Performance Interview Questions and Answers focuses on “Fixed-Wing Aircraft – Operational Performance”.

1. Factors that affect the aircraft performance during take-off are mass of the aircraft during take-off, air density, temperature and runway conditions.
a) True
b) False

Explanation: Factors that the affect aircraft performance during take-off are mass of the aircraft during take-off, air density, temperature and runway conditions. The speed of wind and flap setting and airframe contamination are the other factors that affect the aircraft performance during take-off.

2. MTOW stands for _________
a) Maximum permissible Take-Off Weight
b) Minimum permissible Take-Off Weight
c) Maximal permissible Take-Off Weight
d) Minimal permissible Take-Off Weight

Explanation: MTOW stands for Maximum permissible Take-Off Weight. MTOW is the maximum weight of an aircraft at which a pilot is allowed to take-off the aircraft. This is caused due to structural limits of the aircrafts.

3. The basic requirements for safe flight are that the space required for the aircraft to maneuver should never exceed the space available.
a) True
b) False

Explanation: The basic requirements for safe flight are that the space required for the aircraft to maneuver should never exceed the space available this is because if the space is insufficient for the aircraft to perform a maneuver then there may be a failure of the aircraft due to this aircraft getting hindered by some factor.

4. What is operational performance of an aircraft?
a) The performance of an aircraft which is related to the aircraft above ground level
b) The performance of an aircraft which is related to the aircraft engine
c) The performance of an aircraft which is related to the aircraft when it is on ground
d) The performance of an aircraft which is related to the aircraft taxing

Explanation: Operational performance of an aircraft is the performance of an aircraft which is related to the aircraft above ground level. It includes aircraft cruise angle, altitude, temperature, engine failure, fuel management and also take-off performances.

5. Aircraft weight is the only controllable variable that can be used to ensure that space required for the maneuver doesn’t exceed the space available.
a) True
b) False

Explanation: Aircraft weight is the only controllable variable that can be used to ensure that space required for the maneuver doesn’t exceed the space available. As a rule of aircraft performance the space required for an aircraft to maneuver must be always less than the space available. As a result the aircraft weight much be checked to avoid complications that occur due to space required being more than space available.

6. What is MTOW of an aircraft?
a) The maximum weight of an aircraft at which a pilot is allowed to attempt to land the aircraft
b) The maximum weight of an aircraft at which a pilot is allowed to attempt to take-off the aircraft
c) The minimum weight of an aircraft at which a pilot is allowed to attempt to take-off the aircraft
d) The minimum weight of an aircraft at which a pilot is allowed to attempt to land the aircraft

Explanation: MTOW stands for Maximum permissible Take-Off Weight. MTOW is the maximum weight of an aircraft at which a pilot is allowed to take-off the aircraft. This is caused due to structural limits of the aircrafts.

7. A flight is carrying 130 passengers over a distance of 990km with a seating capacity of 140 and a yield of 7.9. Calculate the load factor.
a) 90%
b) 92.86%
c) 89.556%
d) 67.35%

Explanation: The answer is 92.86%. Given number of passengers travelling = 130, seating capacity=140 and a yield of 7.9.
We know percentage load factor=$$\frac{no. \, of \, passengers \,travelling*distance \,travelled}{no. \,of \, seats*distance \, travelled}$$ x 100%
On substituting the values,
Load factor=$$\frac{130*990}{140*990}$$ x 100%

8. A flight is carrying 130 passengers over a distance of 990km with a seating capacity of 140 and a yield of 7.9. Calculate the passenger revenue.
a) 143780
b) 1016730
c) 1094940
d) 1524263

Explanation: The answer is 1016730. Given number of passengers travelling = 130, seating capacity=140 and a yield of 7.9. We know that passenger revenue=Revenue passenger kilometers*yield where Revenue passenger kilometers=number of passengers travelling*distance travelled.
On substituting the values
Revenue passenger kilometers=130*990
Revenue passenger kilometers=128700
On substituting revenue passenger kilometers in passenger revenue formula
Passenger revenue=128700*7.9.

9. A flight is carrying 130 passengers over a distance of 990km with a seating capacity of 140 and a yield of 7.9. Calculate the Revenue passenger kilometers.
a) 138600
b) 124570
c) 128700
d) 124560

Explanation: The answer is 128700. Given number of passengers travelling = 130, seating capacity=140 and a yield of 7.9. We know that revenue passenger kilometers=number of passengers travelling*distance travelled.
On substituting the values
Revenue passenger kilometers=130*990
Revenue passenger kilometers=128700.

10. A flight is carrying 130 passengers over a distance of 990km with a seating capacity of 140 and a yield of 7.9. Calculate the available seats kilometer.
a) 148700
b) 138600
c) 128700
d) 154800

Explanation: The answer is 138600. Given number of passengers travelling = 130, seating capacity=140 and a yield of 7.9. We know that available seats kilometer=number of seats available*distance travelled.
On substituting the values
Available seats kilometer=130*990
Available seats kilometer=128700.
