Weight And Balance Flashcards
Which items are included in the basic empty weight of an aircraft?
a) Optional equipment, unusable fuel, and all operating fluids including engine and transmission oil, and hydraulic fluid (if equipped).
b) Only the airframe, powerplant, and optional equipment.
c) Full fuel tanks and engine oil to capacity.
A) Optional equipment, unusable fuel, and all operating fluids including engine and transmission oil, and hydraulic fluid (if equipped).
Operating below a minimum weight limitation could adversely affect the handling characteristics of the helicopter.
a) True.
b) False.
A) True
Operating above a maximum weight could result in
a) Structural deformation.
b) Structural failure during flight if encountering excessive load factors, strong wind gusts, or turbulence.
c) All are correct.
C) All are correct.
It is always safe to operate a helicopter at its specified maximum gross weight.
a) True.
b) False.
B) False.
Although a helicopter is certificated for a specified maximum gross weight, it is not safe to takeoff with this load under some conditions.
a) True.
b) False.
A) True
When the CG is too far forward
a) The helicopter hangs horizontally.
b) The helicopter hangs nose low.
c) The helicopter hangs nose high.
B) The helicopter hangs nose low
When the CG is too far aft
a) The helicopter hangs horizontally.
b) The helicopter hangs nose low.
c) The helicopter hangs nose high.
C) The helicopter hangs nose high.
What may occur if the CG is located forward of the forward CG limit?
a) The pilot could rapidly lose rearward cyclic control as fuel is consumed.
b) May be impossible to decelerate sufficiently to bring the helicopter to a stop.
c) All are correct.
C) All are correct.
What may occur if the CG is located forward of the forward CG limit?
a) In the event of engine failure and the resulting autorotation, there may not be enough cyclic control to flare properly for landing.
b) May be impossible to accelerate sufficiently for takeoff.
c) All are correct.
A) In the event of engine failure and the resulting autorotation, there may not be enough cyclic control to flare properly for landing
Without proper ballast in the cockpit, exceeding the aft CG may occur when
a) A lightweight pilot takes off solo with a full load of fuel located aft of the rotor mast.
b) A lightweight pilot takes off solo with maximum baggage allowed in a baggage compartment located aft of the rotor mast.
c) All are correct.
C) All are correct.
What is the result of loading a helicopter so that the CG is aft of the rearward limit?
a) Insufficient forward cyclic control to fly in the upper allowable airspeed range.
b) Insufficient aft cyclic to decelerate properly during an approach.
c) Inability of the pilot to recognize this dangerous condition when hovering in a strong headwind.
A) Insufficient forward cyclic control to fly in the upper allowable airspeed range.
The horizontal reference datum is an imaginary vertical plane or point from which all horizontal distances are measured for weight and balance purposes. This line
a) Is always located at the nose of the helicopter.
b) Is always located at the rotor mast.
c) May be located at the rotor mast, the nose of the helicopter, or even at a point is space ahead of the helicopter.
C) May be located at the rotor mast, the nose of the helicopter, or even at a point is space ahead of the helicopter.
