CHIEF INSTRUCTOR BRIEFING & OPERATIONAL NOTES

The Q400 has considerable propeller slipstream over the horizontal tail. During go-around or full power application, be prepared for a strong pitch-up tendency that requires prompt forward control pressure and electric trim.

AIRCRAFT TRIVIA & HIGHLIGHTS

1FACT #1

The "Q" in Q400 stands for "Quiet" due to its computer-controlled Active Noise and Vibration Suppression (ANVS) system.

2FACT #2

With a cruise speed of 360 knots (667 km/h), the Q400 flies virtually as fast as a jet over routes under 500 miles, but burns up to 30% less fuel.

3FACT #3

Each of its two engines generates over 5,000 horsepower – more than two modern Formula 1 cars combined per engine!
