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

High temperature, high humidity, and low pressure all reduce air density, resulting in a high density altitude and degraded aircraft performance.

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

When a weight's arm is measured forward of the datum, it is assigned a negative value, producing a negative moment in CG calculations.

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

Performance penalty tables let pilots adjust certified performance data to account for non-standard conditions such as an inoperative anti-ice system.

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

RTOW is the lowest weight derived from structural, field performance, obstacle clearance, and en-route climb limit analyses for a given departure.

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

At higher gross weights, more lift is needed; since lift = ½ρV²SCL, a higher airspeed (V) is required to produce that lift at the maximum lift coefficient, raising stall speed.
