roulishollandais,
We seem to be on slightly different wavelengths.....
A CMM is aimed at the
maintenance engineer who gets a supposedly faulty piece of equipment dumped on his bench, and has to find and fix the supposed fault, and then recertify the equipment as airworthy.
It is
not aimed at either a pilot or (in the olden days) at a flight engineer, who don't necessarily have the specialist engineering background to 'decipher' electronic circuit diagrams or test specifications in a document like the CMM.
They refer to the
functional documentation (aircraft flight manuals, etc.).
Testing software or equipment is a very strategic action.
I think you're confusing testing during development and 'operational' testing....
The ATEC is strictly a
production and '
operational' piece of test equipment. It has no relation with the equipment used for software and hardware testing and validation during design and development.
And indeed, ATECs have been sold to other clients, exactly like Honeywell, HP and SFENA ATEs.
