JAA/ICAO Defs of T.O. Performance
Can someone help me with the following questions? I live in the states and I'm not familiar with the acronyms used.
1. What is the def of TORA?
2. What is the def of TODA?
3. What is the def of ASDA?
4. ASDA is TORA + what?
5. An increase in stopway would increase:
A. TORA
B. ASDA
C. TODA
6. A change in clearway would change?
A. TORA
B. ASDA
C. TODA
I think ASDA is the same as ASD (accelerate stop distance) in the states...but I'm not sure.
Thanks for your help.

Why not?---my turn
ASDA: distance to accelerate to the decision speed V1 and then stop---unfactored
stopway: a length of usable surface not designated a runway i.e the 'chevron' area that will not cause significant damage to the plane
clearway: an obstacle free area [like water or a field or rusty nails] over which a portion of the OEI acceleration section to the screen/ fence [first segment] to V2 may be allowed
ASDA =accelerate stop distance =TORA + stopway
TORA=Takeoff runway the aircraft must be airborne at V2 [for the accelerate-go] at 35' above the end of the TORA with one engine inoperative: for all engines the FAR TORA includes a safety factor of [half the airborne distance to 35' plus 15%
TORA+CLEARWAY = TODA
'sometimes the distance TORA or TODA must be reduced to account for LOW CLOSE IN OBSTACLES affecting the accelerate-go'
so
1. b
2. c
yes, ASD [FAA] = ASD [CAA]
but in the US TORA=TODA=ASDA
[this is going to change if it already hasn't in the US]

Oh I forgot
the 'A' as in ASDA means available
takeoff runway available TORA
takeoff distance available TODA
and for JAA I believe the all engines factor required is 1/3 the airborne distance plus 17%
