Quote re comment on Shoreham aerodrome:
"Not really "decent" - only 1036 m of hard runway."
This type of flying is completely unfamiliar to me, and I've yet to read the AAIB report. I did float a tentative question soon after the accident, however, which was not answered and I now hesitate to repeat.
The proportions of the Shoreham hard runway (length/width) are not unlike those of a typical fast-jet runway, which would be over double the length. I gather that the parameters of IAS and height are used as gates at certain points in these manoeuvres, but even so the smallness of the runway could give a visually-misleading impression of height. Is that a known factor in aerobatics training, or irrelevant?
