This is a Sources Sought notice for heavy aircraft simulator services to support the USAF Test Pilot School, not a formal solicitation. The requirement is for Boeing and Airbus wide-body, full-motion Level-D simulators, which must be co-located to allow side-by-side comparisons. The anticipated contract is a one-year purchase order with an estimated budget of $34,000,000. The services will also support student Test Management Projects, with students and staff occupying the simulators for these events. Interested vendors must submit capability statements, and a formal RFP may follow based on the market research.
