FAA Private Pilot Helicopter (PRH)Performance and LimitationsMedium
A helicopter's performance charts indicate a maximum gross weight of 2,800 lbs under current conditions. The aircraft's empty weight is 1,800 lbs. If the pilot and passenger weigh 350 lbs combined and 150 lbs of baggage is loaded, what is the maximum fuel (in pounds) that can be carried?
- A400 lbs
- B650 lbs
- C350 lbs
- D500 lbs
Show answer & explanationAnswer & explanation
Correct answer: D. 500 lbs
First, calculate the current weight: Empty Weight (1,800 lbs) + Pilot/Passenger (350 lbs) + Baggage (150 lbs) = 2,300 lbs. Then, subtract this from the maximum gross weight: 2,800 lbs - 2,300 lbs = 500 lbs. This is the maximum fuel that can be carried.
Why the other options are wrong
- A. Incorrect. This calculation error might result from misadding the weights.
- B. Incorrect. This would exceed the maximum gross weight.
- C. Incorrect. This would be the answer if there were 150 lbs less available for fuel.
Weight and Balance Calculation
Weight and balance calculations ensure the helicopter's total weight and center of gravity remain within safe operating limits.
- Maximum Gross Weight is a critical limit.
- Subtract all known weights from Max Gross Weight to find remaining capacity.
- Fuel weight must be accounted for accurately.
Memory trick: Start big, subtract the knowns, find the fuel space.
