surely in this day and age of technology there should be proximity switches on the cowl doors ? All other doors whether they be passenger, service, type 3, freight or avionics bay doors have proximity switches.
I am not splitting hairs, but the 'quick fix' of fitting proximity switches are of little use - they will only tell you once the cowl had been blown open. At rest with the cowl latches unlocked, they would still appear to being 'locked' as gravity forces them together. Another type of switch mechanism to register the positive latch engagement would be required.
