The routine we are taught is as follows, all part of the pre-flight

1. decide on appropriate approach speed for conditions

2. in the event of a launch failure (not just cable brake) lower the
nose to an appropriate attitude

Wrong, very wrong, very dangerous. The correct sequence is:

1. Push the stick forward and pull the release knob.

2. If possible, land ahead on the remaining runway.

3. If you're too high to land ahead, you have all the time to decide
your further actions. This can be an abbreviated circuit or a downwind
landing, depending on the circumstances.

And yes, doing a 180 too hasty will put you in a situation where you
don't have enough runway to land. So whatever you do, don't panic.
Everything else depends.
