One of the large blue books in the RAF had in the preface words to the effect of 'These Rules cannot cover every situation. If you follow the Rules when you shouldn't, it's your fault as captain of the aircraft. If you break the rules when you shouldn't, it's your fault as captain of the aircraft.'
A discussion with instructors went along the lines of.
"That's not fair"
"Life's not fair"
".....fair point"
"Look, break the rules for the minimum time possible and be prepared to justify yourself at a subsequent Board of Inquiry. Remember Admiral Byng"
