Cruise Speed (Normal)473 knots. Cruise Speed (Normal). Compared to the average Turbofan-powered Narrow-body Commercial Passenger Plane, which cruises at 458 knots (527 mph) to maximize range and can cruise at a maximum speed of 472 knots (543 mph), the Bombardier CRJ700: 1  Maximizes its range at a 11 knot (13 mph) lower speed (a 2.4% margin).
With a 90-hp 4-stroke engine it runs at 13.9 mph at 4,000 rpm (a typical cruising speed), while a less expensive 60-hp 4-stroke of the same make pushes it at 13 mph at 4,000 rpm. For a less than 1 mph difference, you can save money on the engine and at the gas pump.
