Category A PC1 or PC2
Hello everybody,
I would like to discuss performance class 2 operations as compared to CAT A / PC1 operations on the S92.
If you are at MTOW (26.500lb), MSL, 1013, zero wind, 32°C, your TDP would be 47kt and you would be able to safe reject in 2.343ft (iFly precision) =)
And for the same conditions you will have to limit your take off mass as temperature goes above 32°C.
But if we use the chart for PC2:
MAXIMUM TAKEOFF AND LANDING GROSS WEIGHT
BASED ON 150 FPM OEI CLIMB AT 1000 FT ABOVE THE TAKEOFF SURFACE
CT7−8A MAXIMUM CONTINUOUS OEI POWER BEST ROC SPEED
We have a limitation that starts from 34°C.
Does anyone knows the reason for this difference?
If we are taking off from a paved clear runway shouldn´t those two be the same?
Best regards,
Vidual
