Well I don't think ground slope would be a problem. Hangars and aprons are
generally designed to be perpendicular to local gravity to stop unbraked
machines departing. I actually have two spirit levels in the cockpit - one
for the days when one had to lift the tail to check sight gauge contents, and
now a transverse one to verifty the two sight gauges read the same each side !
so checking (and chocking) would be esay.
I understand our Kit. no. 1 pilot was a V-bomber jockey - but I've never seen
him on the net. What did/do they do/try to do, in large planes ?
Yes, the bungee won't do. I was hoping that in a similar way to the route
micrometers took some years back, the humble caliper gauge would have become
digital too. Though there is more to adding a readout from a digital display
than most people would want to get involved in.
Moire fringe gratings (as used in precision coordinate measuring machines and
lathes, before lasers came in ) come to mind, but that was pretty expensive
technology.
Keep thinking guys
