Flight Testing Highlights

  • Tracking prototype, certification flight test, and engine manufacturer flying testbed aircraft operating worldwide.
  • Includes Boeing 777-9 (777X) flight test airframes (N779XW, N779XX), 737 MAX 10 (N27751), Airbus A321XLR (F-WXLR), and engine testbeds from Rolls-Royce (747-400 N787RR) and Pratt & Whitney (747SP C-FPAW).
  • Airframes conduct aerodynamic flutter testing, avionics envelope expansion, extreme weather trials, and engine airborne telemetry.
  • Monitored via open Mode S and ADS-B receiver telemetry during test sorties from major flight test facilities.
