Category A - external equipment
The Category A performance, Mass limitations - specified for:
Clear heliport - external equipment is a factor
VTOL(1-3) - external equipment is NOT a factor
Logical, when it comes to Cruise flight OEI, external equipment is a factor at Vy (65 kts) - actually in the exact same way as with Clear heliport.
I'm having problems with understanding how Clear heliport Cat A ops. are effected by external equipment when TDP/LDP's are up to 40 kts (with the same deductions as at 65kts)
and
VTOL ops. are not effected by external equipment even when FLIR and the SX-16 are in the downwash - vertical drag region.
Any ideas?
