REJECTED TAKEOFF

UNCONTROLLED FLIGHT INTO TERRAIN: REJECTED TAKEOFF

The airlines make exceptional effort to both brief and be ready for the RTO. They even include it as a maneuver on all recurrent check rides under AQP.

General Aviation for single engine planes does not have such a maneuver, nor does it have any mention of in training material.

The main emphasis is to know the abort points during any takeoff such as insufficient speed at a certain marker, or stagnating airspeed, or unknown vibration, etc. The pilot should be thinking about the runway length and how aggressively braking is going to occur if an RTO is required.

SOLUTION: 

Get with your CFI and discuss both the criteria for rejecting a takeoff (what we will and will not abort for) and the reference points that you want to use. Some common techniques are to use runway distance remaining markers, key points on the runway, or an elapsed amount of time from throttle advance to liftoff.

As an example, you could use a timer and know that in your plane, you should be at 70 knots and rotating at the 20 second mark. If not, effect an immediate abort. Talk over your after-abort items with your CFI as well. Items such as calling the tower to advise of abort, whether you should taxi clear or not after abort, are the brakes hot, did you leave any debris on the runway, etc.

All are good things to brief and try out with a CFI. As a test, have your CFI advance power for you but not give you full RPM. See if your abort parameters become obvious when you have passed a point or a certain amount of time and the plane still has not reached rotation speed.

The point here is to think about this and discuss now when you have the opportunity to be ready for this. If you are surprised in an RTO, it might not work out well for you.
