BAvn Bachelor of Aviation Aircraft Performance and Weight & Balance 3

Question 1

Which atmospheric condition produces the highest density altitude at a given elevation?

Accepted Answer

Hot, high humidity, and low pressure

Answer

Cold and low humidity

Answer

Cool and high pressure

Answer

Standard ISA conditions

Question 2

In weight and balance, a moment is said to be 'negative' when:

Accepted Answer

The arm is forward of the datum (a negative arm value)

Answer

The arm is aft of the datum

Answer

The weight is above the CG

Answer

The aircraft is below MTOW

Question 3

What is the purpose of a 'performance penalty' table in an aircraft flight manual?

Accepted Answer

To quantify performance degradation from specific non-standard conditions like inoperative equipment

Answer

To show fuel cost at high altitudes

Answer

To list speed limits by altitude

Answer

To calculate turbine temperature margins

Question 4

What is meant by 'regulated takeoff weight' (RTOW)?

Accepted Answer

The maximum weight permitted for a specific takeoff considering field length, obstacles, and climb limits

Answer

The design maximum structural weight

Answer

The weight after all fuel is consumed

Answer

The weight limit set by air traffic control

Question 5

Which factor causes an increase in aircraft stall speed at high gross weights?

Accepted Answer

More lift required to support greater weight, needing higher airspeed

Answer

Reduced parasite drag

Answer

Greater wing area at higher weights

Answer

Increased engine thrust

Question 6

An aircraft is loaded such that the CG is within limits but close to the aft limit. How does this typically affect cruise performance?

Accepted Answer

It reduces trim drag by requiring less down-force on the stabilizer

Answer

It increases induced drag due to a higher tail download

Answer

It increases fuel consumption significantly

Answer

It reduces climb rate regardless of thrust

Question 7

What is the primary purpose of the aircraft's weight and balance 'envelope' diagram?

Accepted Answer

To graphically depict the allowable CG range as a function of gross weight

Answer

To show fuel burn over time

Answer

To determine maximum range

Answer

To plot climb performance curves
