Hi
Speaking as someone who only does very occasional underslung work, I would like to point out that every underslung check ride I have every done (military and civil) has been carried out from an airfield. Pick up barrel of concrete, fly circuit, avoid built up areas, houses, try and cross roads at right angles etc. but without doubt we have potentially overflown members of the public. It is possible that one of these flights might have flown directly over a school bus driving down a country lane!
Is the suggestion, that all future check rides would have to be carried out over some secure part of Salisbury Plain or similar?
