Loading an Aircraft for Flight

When calculating CG, which formula is used?

Moment ÷ Weight

What happens if loaded CG falls aft of the published limit?

Aircraft may become uncontrollable in pitch

Why might ballast be required even if total weight is within limits?

CG still falls outside allowable range

What component's location most strongly affects CG during a reconfiguration?

Seats and baggage

Which of the following is the correct way to document a weight and balance change?

Record it in the maintenance logbook

What is the result of summing all weight deltas in an equipment change?

It shows the net change in empty weight

If a loaded CG is found to be out of limits, which of the following is the most effective first step?

Off-load or shift baggage and passengers

What distinguishes permanent ballast from temporary ballast?

It is permanently attached and marked not to remove

Which of the following would NOT be part of an aft adverse-loaded CG check?

Loading all forward compartments

During a forward adverse CG check, how is fuel handled when the tanks are aft of the CG limit?

Load only minimum fuel

What does a forward CG shift typically result in?

Increased stall speed and reduced pitch stability

Why must an aircraft be reweighed after structural alteration?

The empty weight and CG are no longer accurate

Why is it important to use a four-column weight and balance chart?

It simplifies calculating moment and CG

What is the primary responsibility of the pilot-in-command (PIC) regarding weight and balance?

Ensure the aircraft is loaded within weight and CG limits before takeoff

What is the purpose of an adverse-loaded CG check?

To ensure no legal configuration causes a CG limit violation

What determines whether reweighing or calculation is used after an equipment change?

The availability of accurate weight and arm data

Which is true of temporary ballast?

It must be secured and labeled with removal warnings

What is the first step when preparing to calculate an aircraft's loaded CG?

Obtain the empty weight and EWCG

Why is the aircraft's empty weight and EWCG only of secondary concern during preflight planning?

Because only loaded weight and CG impact flight safety

Why should ballast be placed as far forward or aft as possible?

To minimize the amount of ballast needed

What is the significance of the arm value in CG calculations?

It determines the distance from the reference datum

Which scenario might require permanent ballast?

An alteration that shifts the EWCG out of limits

After calculating required ballast, what is the next step?

Round up to the next pound and recalculate CG

If the loaded CG is 2 inches too far aft, what information is needed to calculate required ballast?

The loaded takeoff weight and distance from ballast location to CG limit

When evaluating aircraft loading, what is the key regulatory requirement?

Aircraft must be within published weight and CG limits
