How would this affect flight instruction? Hover square, fast stops, precision transitions etc. All below 500 ft and none of it for the purposes of take off or landing.
presumably as these exercises are completed on airfield they would come under the banner 'helicopters manoeuvering' and therefore:
"(i) Subject to paragraph (ii), a helicopter shall be exempt from the 500 feet rule
if it is conducting manoeuvres, in accordance with normal aviation practice,
within the boundaries of a licensed or Government aerodrome or, with the
written permission of the CAA, at other sites.
(ii) When flying in accordance with this exemption the helicopter must not be
operated closer than 60 metres to any persons, vessels, vehicles or
structures located outside the aerodrome or site."
should hopefully still be safe there...
