No doubt it could be a useful tool when dealing with people, but the "Attitude" we refer tois the position of an aircraft sitting on the tarmac. Is it "level" or leaning in one direction or another? That's important to know when reading the dripsticks, the external fuel gauges, to determine if the aircraft has been fueled properly. The attitude monitor sits in one of the wheel wells. It looks like an advanced carpenter's level, with a large sight glass divided into a grid of squares.

Issue 7, which is the current version of the Attitude Monitor, is built to – and repaired to – specs that require a nitrogen gas chamber for filling it with fluorescein and for inserting the gas bubble. That can only be done at the Thales facility in the UK or at Erie Aviation, which offers new units and a full warranty and repair service. All repair batches have a sample unit used for destructive testing with UV rays to ensure the longest possible life.
