I agree with MT as well. As an instructor, I only ever pull the bung if I am absolutely confident that I can handle the emergency if the student/pilot-on-check stuffs up or takes a poor option. My hand is almost on the stick to prevent an error.

It is never below 300' AGL unless I can land ahead.

Prior to being an instructor, I was always disappointed when the annual check instructor did *not* pull a low level release because I was confident that I could do them but was never tested. I have had an AEI ask to practice a 300' release in a strong wind, as he felt the same.

Recently at Caboolture we had a power pilot who lost power on take off at a very low height and he just pushed the nose forward and pancaked his beautifully restored aircraft. Obviously he had a habit of "hanging on the prop" on take off and learned the hard way.

I doubt there is any training value at all in 400 to 500 feet.

I believe that there is some training value in such a flight:

The ability to fly and manoevure confidently at low level without getting 
ground fright. (i.e. if I had the option to do a low level circuit for a safe 
landing on field after a rope break, that would my first option).

Also low level flight is experience with ridge flying too.

Also in still wind conditions, a 180 degree turn can be considered.

Such manoevures need to be demonstrated at altitude, i.e. demonstrate a 180 
degree change of heading with minimum height loss, in a Grob G103, banked at 60 
degrees,  60 knots airspeed, in still air, height loss in a 180 degree turn is 
150', with a diameter of the turn of 120m

Obviously needs to be done with a proper briefing, exercise at altitude,  
exercise at 400' to 500' AGL, post flight de-brief.

The plane doesn't know how far it is above the ground.
