3.5. TAKEOFF DECISION POINT (TDP)
The TDP of 100ft/30.5m HAT is located at a ground distance of 300ft/91.4m behind
the center of the helipad or landing area when there is no obstacle in the takeoff
path.
To ensure a safe CTO or RTO, the confined heliport/VTOL technique is flown to
ensure that 300ft/91.4m exists between the helicopter and the far edge of the confined
heliport.
Variable obstacle heights (Ref. Table 11-3.1):
For varying obstacle heights, the pilot maintains the same sight picture from
a TDP HAT of 100ft/30.5m to 200ft/61.0m above the surface of the heliport/
helipad. A TDP HAT of 200ft/61.0m (maximum) will be attained at a ground
distance of 600ft/189.9m ft behind the center of the helipad.
Obstacle heights FWD and AFT of the takeoff point must be known.
NOTE
:
All HAT data not barometric corrected.
