Is there anything wrong with rotating 5-10kts above Vr? (C172)

Asked by: 1921 views General Aviation

Seems like you can make a smoother takeoff by doing this when you're heavier and have plenty of runway. I don't like hearing the stall horn chirping on takeoff

    1. Poor practice.
    2. Danger of wheelbarrowing.
    3. Additional wear/tear on gear, especially the nosewheel and strut.

    Plus, you use more runway.

    The manufacturer is required to determine the rotation speed. That speed is determined at gross weight and therefore should be adequate for most conditions.

    The performance charts for takeoff will be predicated on rotating at that speed.

    If you are following the manufacturer’s published numbers for rotation, and are hearing the stall horn chirp, perhaps it’s out of adjustment, and sounding when it shouldn’t??

    Seems, best is to understand why we do the procedures and maneuvers as prescribed, then understand reasons for, pro & con to alter them based on conditions and circumstances.
    Let the plane fly itself off the runway.
    Slight back pressure at said airspeed is all that is needed.
    Keeping the nosewheel on the ground longer impedes takeoff, the plane accelerates much better through the air than on the runway.
    If you are pulling back too much or too soon on the stick/yoke you will have problems.
    You might be forcing your ac into the air in ground effect, not good, and in fact in tricycle gear you want to start with slight forward pressure to put weight/ pressure on your nose wheel for positive steering until your rudder can control yaw affirmitaively, which happens quickly.
    A specific speed for rotation is relative, in that ac weight effects your lift, but so does air density.
    I soloed glider August 1, C172 Aug 18, temp F 93 deg.
    I flew solo c172 Dec 3rd, temp F 34, I was at pattern altitude well before I reached the end of the runway. I thought something was wrong w my ac. Too high. Adjust your expectations, think where you will be on or over the runway at different points in your fakeoff and landing events. Anticipate. Air density, wind, weight, humidity, EVERYthing that effects your ac performance, know it before it happens.
    If your stall horn is working properly, you should not be hearing it on take off.
    It tells you AoA is too high, plus you are in ground efect so flying up out if ground effect too quickly can bring on a stall.
