TAKE-OFF FIELD LENGTH - APR ON
Hawker 850XP Pro Line 21 Airplane Flight Manual
Associated Conditions
The performance is based on the following assumptions:
NOTES:
1. To take account of engine antice on the take-off weight, add 10° C to the actual
air temperature before entering the charts.
2. The wind grids are factored in such a way that an effect of not more than 50% of
headwinds and not less than 150% of tailwinds is obtained. Reported winds
may therefore be used directly in the wind grids. When a takeoff is to be made
into a headwind exceeding 40 kts, the charts are to be read at 40 kts.
The following techniques have been assumed:
Rolling Start Takeoffs
Where rolling start takeoffs are used, reduce all available field lengths by 100 ft when
establishing take-off weight based on field length.
Engines
Both engines are at take-off thrust with APR armed.
Failure of the critical engine occurs at V
1
.
Engine Bleed Air
Air conditioning bleed off; see NOTE 1 for the effect of
engine antice bleed.
Flaps
Take-off setting, either 15° or 0°.
Landing Gear
UP selected after lift-off.
Runway
Hard dry.
Normal Takeoff
Both engines are run up to normal take-off thrust with APR
armed, and then the brakes are released. Rotation is
initiated at V
R
.
Engine Failure
Rejected Takeoff
Failure of one engine is recognized at V
1
. Both thrust
levers are closed, maximum wheel braking using anti-skid
is applied, airbrakes are opened and the airplane brought
to a stop.
Engine Failure
Continued Takeoff
Following the failure of one engine at V
1
, maximum thrust
is automatically set on the operating engine. Rotation is
initiated at V
R
and climb away is made to achieve V
2
appropriate to the flap setting at 35 ft.
For field performance computations, the landing gear is
selected UP 3 seconds after lift-off.
NOTE: No reduction in stopping distance is credited for the
use of thrust reversers.
