Cruising Speed

What is a realistic cruising speed in the Q400 should you cruise at, at FL250?


At FL250(Which is close to the Service ceiling) I believe about 235-245 IAS

I think the maximum speed on the aircraft at FL250 is around 235-237 knots before you get vio warnings, I would say 230-235 Knots just to account for changes in wind.


ok, thank you both!


Hey! According to Eurocontrol’s Aircraft Performance Database. The Dash 8 Q400 has a service ceiling of FL250 and usually cruises at or a bit below 360 knots TAS (True Air Speed). Check the link below:

You can also use this site for performance data of other aircraft. Most of the larger and more widely used AC are up to date.
