Flight Planning and Performance Flashcards
Imaginary point where aircraft’s weight is concentrated
Center of gravity (CG)
Imaginary vertical plane from all horizontal distances are measured
Reference datum
Includes the weight of the standard airplane, optional equipment, unusable fuel, including all operational fluids including full engine oil
Basic empty weight
This is the small amount of fee in the tanks that cannot be used inflight and feel drained on the ground
Unusable fuel
Weight of an aircraft before takeoff
Ramp weight
Ramp weight less the fuel burned during engine start, run up and taxi
Takeoff weight
Takeoff weight less the fuel burned en-route
Landing weight
Weight of usable fuel, flight crew, passengers and baggage
Useful Load
Weight of passengers, baggage and cargo
Payload
Maximum weight allowed for ground operation
Maximum ramp weight
Maximum weight before takeoff
Maximum takeoff weight
Maximum weight before landing
Maximum landing weight
Fuel available in flight
Usable fuel
Distance from reference datum
Arm
Measurement of the tendency of the weight to cause rotation of fulcrum. Length multiplied by weight
Moment
This is a major factor in airplane construction and operation.
Weight
It is the force generated by the gravitational pull of the earth on the total load of the aircraft. This directly affects the performance of our aircraft
Weight
State the disadvantages of an overweight aircraft
- Longer takeoff and landing roll
- Higher Takeoff Speed
- Poor Climb Performance
- Lower Cruising level
- Reduced cruising speed
- Less Maneuverability
- Reduced Range and Endurance
- Higher Stalling Speed
One gallon of AVGAS is how much in pounds?
6 lbs
One gallon of oil is how much in pounds?
7.5 lbs
1.5 gallons or 6 quarts of oil is how much in pounds?
11.25 lbs
A point at which the entire weight of the aircraft is assumed to be concentrated, and where the counterclockwise turning moments are balanced by the clockwise turning moments
Center of Gravity (CG)
A point at which an airplane would balance if suspended
Center of Gravity (CG)
State the effect of CG Position on Aircraft Performance when it is too forward (nose heavy)
- Lack of elevator authority (specially during flare)
- Higher angle of attack
- Drag will increase
State the effect of CG position on aircraft performance when it is too far aft (tail heavy)
- Unstable airplane
- Very difficult to recover from a stall
This is the distance from the datum. Measurements aft of the datum are positive figures and forward of the datum are in negative measurements
