Q400 will burn about 1.1 tonnes per hour in the cruise. If we fly the Q400 at an intermediate cruise setting (which is what we are doing now) then this figure can be as low as 780kgs per hour and even better at LRC

How does FF during LRC compare to MRC?

Is LRC often or always preferred?

The RJs on takeoff will burn about 5 tonnes per hour, the Q400 will burn about 1.6 tonnes per hour.

How about reduced thrust procedures?
