APS Groundschool day 2 Flashcards
TORA
Takeoff Run Available –> Runway length suitable for ground run when taking off (dus zonder clear of stopway)
Stopway
Area behind the runway which can be used for RTO. It is capable to hold the aircraft weight
Clearway
An area beyond the paved runway, free of obstructions. can be grass, concrete etc
TODA
Takeoff Distance available
TORA + Clearway
ASDA
Accelerate-stop Distance Available
TORA + Stopway
Balanced V1
TODR = ASDR
Balanced field
TODA = ASDA
Screenheight dry + wet
Dry = 35 ft Wet = 15 ft
V1 (decision speed) must be: (greater/less than)
V1 = decision speed
- Greater than Vmcg
- Less than Vmbe
- Less or equal to Vr
Takeoff pitch settings
TO pitch = 15 degrees
N-1 TO pitch = 12/13 degrees
Rotate 2/3 degrees per second
Vr must be: cannot be less than
- not be less than V1
- not be less than minimum unstick speed + 5% for single engine
- not be less than minimum unstick speed + 10% for all engines
- minimum control speed airborne + 5%
Vr must be: cannot be greater than
the maximum tyre speed (196 kts)
V2 is defined as:
the takeoff safety speed which must be attained at screen height at the end of TODR
V2 must be: must be greater than
- 1G stall speed
- 1,1 VMCA
Runway conditions code + braking action (1-6)
6 = ... 5 = Good 4 = Good to Medium 3 = Medium 2 = Medium to Poor 1 = Poor 0 = nil
