The Consolidated PT-1 Trusty (company designation Model 1) is a biplane primary trainer used by the United States Army Air Service (USAAS) in the 1920s.

It was offered to the USAAS as a replacement for the Curtiss JN-4D trainer, with a choice of Le Rhone or Clerget rotary piston engines.

Visibility was still poor, so Fleet secured US Army permission to rebuild one TW-3 with a new, slimmer fuselage, providing tandem rather than side-by-side seating.

[1] Easy to fly, the Trusty made some students overconfident, and they received a shock when they advanced to faster airplanes with more difficult handling characteristics.

The 'Trusty' was commonly flown without its cowlings in an effort to prevent overheating[3] Whereas the TW-3 had supplemented the JN-4D, the PT-1 supplanted this wholly obsolescent type and was responsible for a radical improvement in the safety record of US Army pilot training.
