Williams International FJ33 family
Williams International FJ33 is a small turbofan family for very light and light business aircraft. It belongs to the FJ33/FJ44 product line, whose two-spool arrangement separates the fan and intermediate-pressure compressor from the high-pressure centrifugal compressor. Air bypassing the core rejoins the exhaust, and the current family brochure describes dual-channel full-authority digital engine control. Williams lists the FJ33-5A among its production engines; ratings and installation data belong to that exact model.
