B787 Max Rate of Climb Speed
 
Hey guys,

Does anyone know how to find the max rate of climb speed on the B787? The max angle is available straight from the climb page, but I haven't been able to find anything in the manuals about the max rate.

Cheers

FCTM
Maximum Rate Climb
A maximum rate climb provides both high climb rates and minimum time to cruise altitude. Maximum rate climb can be approximated by using the following:

787-8
• VREF30+140 knots until intercepting 0.82M

787-9, 787-10
• VREF30+140 knots until intercepting 0.84M

Note: The FMC does not provide maximum rate climb speeds.


Maximum Angle Climb
The FMC provides maximum angle climb speeds. Maximum angle climb speed is normally used for obstacle clearance, minimum crossing altitude or to reach a specified altitude in a minimum distance. It varies with gross weight and provides approximately the same climb gradient as flaps up maneuver speed.
