Risk of flying close to MMO
Hi there,
As per the below:
Overspeed Avoidance during Descent
Manual Flight at Crossover Altitude
When in descent close to MMO, if in manual flight (AP off), the risk of exceedance of the VMO at the crossover altitude is high. In this situation, the flight crew should know its crossover altitude and anticipate the switch to speed by reducing the aircraft pitch on approaching the crossover altitude.
Why is there a risk when MMO switches over to VMO if the pilot is flying at close to MMO? Can someone explain?
Thanks
