I would think the instructors are even less pleased with people who turn back, crash and close the runway for the rest of the day. Especially when there is a perfectly good housing estate for them to crash into, just over the fence.
I came up with the idea of moving off centre line last year. My farmer normally leaves bits of field as EFATO strips for us, but hadn't on this occasion. Freshly ploughed fields, together with a couple of days of recent rain, coincided with a terrible case of carb ice on climb out. I decided to turn back and use the field along side my runway (it being fallow grass) for a downwind landing. In the end, the ice cleared and I didn't land, but I was lined up parallel to my runway.
But the whole episode made me think. Had I been 100m to the left or right, the runway would have been accessible with a minimal amount of turning and its consequetial height loss.
To have this option at many/most established airfields would take a sea change in thinking and in procedures. But something needs to be done as our approaches get more and more congested with houses and industrial units. EFATO has killed several people in the past year and these occurances should be survivable every time.
If you are on the centre line, your chances of making a turn back, in any light aircraft, are vitually nil. If you are off centre line, those chances increase dramatically.
