Vmc vs OAT
Hello,
Vmc decreases as OAT increases.
I take it that the main governing factor for that is the lower thrust/power delivered by the live powerplant due to the lower air density, hence the lower resulting yawning moment at higher OATs.
Question:
Within an increased OAT environment, can't one imagine that the subsequently reduced air density also reduces the aerodynamic controls efficiency which then might need to be compensated by an increased dynamic pressure requirement equating to a greater CAS? This would then reverse the Vmc vs OAT relative evolution.
Any numbers out there that might indicate how possible that can be or not ?
Or, are certification requirements locking things so that it can't happen ?
I was thinking of relatively light underpowered aeroplanes in a high OAT environment
