Use/relationship: An Operational Test Program Set (OTPS) is a collection of hardware, software and data to test Avionics items (all from the same Aircraft or Weapons System) of similar characteristics and functions. By grouping these Avionics items, the hardware, software and data needed by Automatic Test System operators is minimized.
The OTPI is a collection of TPIs that share this hardware, software and data. The TPIs provide connection instructions and data used to trouble-shoot the individual elements of the OTPS.
