Warning: Your Takeoff rotation may be an accelerated stall maneuver demonstration
Are you rotating too fast during takeoff?
Most companies and even an FAA Advisory cirulars recommend rotations at 2.5 to 3 degrees per second to a target pitch of 15-20 degrees 2 engine and 5-8 degrees less than that target if an engine is lost. That means it should take 5-7 seconds for us to reach our target pitch if you do the math.
Yet a few pilots rotate at 7 degrees per second. They tell me they want to maintain V2 to V2+10. This speed is a minimum at 35 feet above the ground not a maximum during climbout.
I think an engine failure just after Vr when the nosewheel leaves the ground is more dangerous than an engine failure at V1.
I always assume during takeoff I might lose an engine after the nosewheel leaves the ground, and if I rotated too fast would lose control by the sudden acelerations along 2 axies.
Have you ever look at how quickly the red low speed bar shoots up to your current airspeed if you rotate at 6-7 degrees per second during takeoff. This is especially true during flex, derated, high alt., high temp. takeoffs. It is like the acceleration stall demos we did during out basic stall training. Why do it during take off so close to the ground? An airplane can stall at any airspeed.
I do agree that if we are a little late or delay our rotation and the airplane has a lot of acceleration a slightly quicker pitch should be used to get back on profile.
I think there are too many pilots doing this and warrants discussion and attention.
