I can only hope the Coroner is switched on and given the correct information, otherwise something like this chestnut might show up as it did in another recent Coroners finding:
Mr X, a local aviator, gave evidence of his
views concerning the aircraft’s altimeter. The reading on the altimeter found at
the crash site was 4,380 feet. Mr X's theory was that the catastrophic
engine failure could have blocked the operation of the altimeter, and therefore
suggests it shows the altitude at which the aircraft was flying when that
failure occurred. This remains a feasible view.
