SPC Weight and Balance 3

Question 1

What is the danger of flying with the CG located too far aft (rear)?

Accepted Answer

The aircraft may become longitudinally unstable and difficult or impossible to recover from a stall

Answer

The aircraft becomes nose-heavy and difficult to climb

Answer

Stall speed increases dramatically

Answer

The aircraft will not be able to rotate on takeoff

Question 2

What is the standard weight used for jet fuel (Jet-A) in weight and balance calculations?

Accepted Answer

6.7 pounds per gallon

Answer

6 pounds per gallon

Answer

7.5 pounds per gallon

Answer

8.35 pounds per gallon

Question 3

A baggage compartment placard reads 'Max Load 100 lbs.' A pilot places 120 lbs of baggage in the compartment but the total aircraft weight is still below maximum gross weight. Is this acceptable?

Accepted Answer

No, structural limits for compartments must never be exceeded regardless of total weight

Answer

Yes, because the overall aircraft weight is within limits

Answer

Yes, as long as the CG is within limits

Answer

No, but only if fuel is reduced to compensate

Question 4

Which document provides the specific CG limits (forward and aft) for a particular aircraft?

Accepted Answer

The Pilot's Operating Handbook (POH) for that aircraft

Answer

FAA Advisory Circular AC 91-23

Answer

14 CFR Part 91

Answer

The Aeronautical Information Manual (AIM)

Question 5

How does a forward CG location affect the stall speed of an aircraft compared to an aft CG location?

Accepted Answer

Forward CG increases stall speed; aft CG decreases stall speed

Answer

Forward CG decreases stall speed; aft CG increases stall speed

Answer

CG position has no effect on stall speed

Answer

Both forward and aft CG increase stall speed equally

Question 6

When computing weight and balance for a flight, a student pilot should use which fuel quantity?

Accepted Answer

Actual fuel quantity planned to be onboard at departure

Answer

Fuel quantity after engine start

Answer

Full fuel capacity regardless of actual fuel onboard

Answer

Minimum fuel required by regulations

Question 7

What is the primary consequence of operating an aircraft above its maximum certificated gross weight?

Accepted Answer

Structural integrity, performance, and handling characteristics may be compromised

Answer

The aircraft will automatically enter an unrecoverable spin

Answer

The aircraft's navigation instruments will become unreliable

Answer

Radio communications will be degraded
