Bouncing needles

I love how people here are comparing modern light aircraft with a 1940s war time fighter built as quickly as possible to get to the front line I doubt you could even compare a flying spit to what they had back then. I.e. Regulations and limitations surviving ww2 aircraft have to meet.

me personally am basing it on actual experience in the Tiger moth, Stearman and (despite being post war) percival prentice, in terms of instrumentation there are no regulations regarding the instruments for aircraft like the spit, these aircraft fly on 'permit to fly' which is the most basic airworthiness certification, even the tigers and Stearmans on public transport C of A don't have the need for modern instruments because they are certified for day VFR flight only.
