How does temperature and weight affect the VNE of a helicopter?
A
VNE increases as temperature and weight increase.
B
VNE decreases as temperature and weight increase.✓ Correct Answer
C
VNE decreases as temperature increases and weight decreases.
Explanation
Helicopter VNE is limited mainly by retreating blade stall, which occurs sooner at higher density altitude and higher weight (more blade angle of attack needed). The Helicopter Flying Handbook therefore notes that VNE decreases as temperature (density altitude) and weight increase.
