(a) enforce the rule that you ALWAYS use ALL the available runway, (tell ATC to sod off if they object to backtracking)
Happily at this particular airport (Buttonville, CYKZ) it would be very uncommon to use anything other than the full runway length. It used to be controlled, but the tower was closed a few years ago when the closure of the airport was anticipated. Then the owner kept the airport open, but the tower did not return. Runway 33 is the most commonly used (an was the runway used for both of these accident airplanes) It has very short undershoot and over run areas. The runway is a bit under 4000 feet, the total space for that runway, is about 4600 feet between roads. So, yes,, we always use the whole runway there!
