787 speed

Does anyone know the normal cruise speed for the 787-800?


I think it’s almost the same on all larger Boeing planes, Mach 0.82-0.83

Officially it’s 493 knots (Mach 0.73) but the infinite flight regions are smaller than a long haul route so it’s down to your discretion.

Yeah I was wondering because the overspeed warning came on at 350kts

To enjoy the the 787,

Takeoff at 140,

Climb at 225

Cruise at 275!

Never heard of the 787-800, but if you mean the 787-8 it’s around 450 knots normally


Overspeed warning is at 350kts IAS (Indicated Air Speed).
This is not the same speed than 490kts TAS (True Air Speed).

When cruising you should use the Mach speed: 0.85 for the 787-8.


Averave is mach .85
