Flight Operations Flashcards
What is maximum zero fuel weight?
The max weight the aircraft can be loaded neglecting the weight of fuel. This can be a limiting factor in larger airplanes associated with bending stress on the wings.
Weight and balance terms for:
- Arm
- C of G
- Arm - Fuselage station
- C of G - Mean aerodynamic chord
Define fuselage station.
Same as “arm” and is the distance from the reference datum usually measured in inches.
Define Mean Aerodynamic Chord (MAC).
Average distance from the leading edge to the trailing edge of the wing. CofG is usually expressed in a % of MAC

Weight addition formula
VB
VB - Max gust intensity speed
The highest speed at which an aircraft can encounter a gust of 66.66 feet per second and not stall or suffer structural damage.
VMCG
VMCA
VMCG - Min control speed on the ground
VMCA - Min control speed in the air
Min calibrated airspeed (CAS) at which it’s possible to maintain directional control if the critical engine fails.
VMBE
Max brake energy speed
The max speed at which it’s possible to stop the aircraft using wheel braking only.
V1
Takeoff decision speed
At this speed, it’s possible to both stop or continue the takeoff with the accelerate-stop distance considered.
V1 must be:
- Less or equal to VR
- Equal or higher than VMCG
- Less or equal to VMBE
V2
Takeoff safety speed
The speed required to maintain the published engine inop climb gradient.
- Must be at least 20% greater than the Vso
- At least 10% greater than min control speed
- Aircraft will still accelerate with 1 engine inop
VREF
Landing reference speed
Speed required at 50’ to meet the published landing distance
Not less than 1.3 x Vso
Takeoff Distance Available (TODA) = ?
TODA = TORA + CLEARWAY
- TODA - Takeoff Distance Available
- TORA - Takeoff Runway Available
Accelerate Stop Distance Available = ?
ASDA = TORA + STOPWAY
- TORA - Takeoff Runway Available
- ASDA - Accelerate Stop Distance
