- Q4
The certificated CG range is 22.0 to 30.0 inches. After computing the loading, the total weight is 1,800 lb and the total moment is 42,480 lb-in. Is the flight within limits, and where is the CG?
- AWe can take off, the C.G. it is at 23.6 inch
- BWe can take off, the C.G. it is at 28.8 inch
- CWe can't take off, the C.G. it is at 20.5 inch
Show answer
Correct answer: A. We can take off, the C.G. it is at 23.6 inch
- Q5
Which combination of loading conditions results in the lowest stall speed and the greatest longitudinal stability?
- ADecreased weight and forward CG
- BIncreased weight and aft CG
- CIncreased weight and forward CG
Show answer
Correct answer: A. Decreased weight and forward CG
- Q6
Why must baggage and cargo be properly secured before flight?
- AAvoid an excess of G forces during maneuvers
- BPrevent CG movement during flight
- CPrevent unwanted CG movements during flight
Show answer
Correct answer: C. Prevent unwanted CG movements during flight
- Q7
Which of the following is a direct effect of operating an airplane at a lighter gross weight?
- AHigher stall speed
- BLower stall speed
- CLonger range
Show answer
Correct answer: B. Lower stall speed
- Q8
Before refueling the aircraft has a weight of 1425 lb. and the total moments are 145,000" aft of datum. You ass 345 lb of fuel on the aircraft. The effective arm is 109" aft of the datum. Calculate the new CG position
- A81.9" aft of datum
- B103.2" aft of datum
- C107.2" aft of datum
Show answer
Correct answer: B. 103.2" aft of datum
- Q9
Your airplane has a maximum takeoff weight of 4.500 lbs. You have filled up your fuel tanks, and your family all have brought too much luggage, making the total weight go up to 4.830 lbs. Can you take off under this conditions?
- AIf the runway is long enough to get airborne, it is allowed
- BYou are not allowed to take off
- CYou must inform the ATC and they have to give you the final permission
Show answer
Correct answer: B. You are not allowed to take off
- Q10
An aircraft has a maximum take-off weight of 1,000 kg, an empty weight of 660 kg, and carries 200 kg of fuel. What is the maximum payload that may be carried?
- A140 kg
- B207 kg
- C317 kg
Show answer
Correct answer: A. 140 kg
- Q11
Which expression represents the relationship between moment (M), force (F), and arm or distance (d)?
- AM = F / d
- Bd = M / F
- Cd = F × M
Show answer
Correct answer: A. M = F / d
- Q12
What does the forward center-of-gravity limit represent?
- AThe imaginary plane defined by the manufacturer from where the moments are measured and the CG is placed
- BThe most advanced position of the CG
- CThe imaginary plane defined by the manufacturer from where the arms or distances are measured used to calculate the moments of the CG
Show answer
Correct answer: B. The most advanced position of the CG
