Pratt & Whitney Canada has a number of engines in development for the medium-twin helicopter category. The latest version of the PT6C family, the PT6C-67E, powers the Eurocopter EC175. Meanwhile, the PW210S is about to enter into service on the now-certified Sikorsky S-76D. Two more PW210 variants will power the AgustaWestland AW169 and the Eurocopter X4. Last year, the Longueuil, Quebec-based engine manufacturer (Booth No. N3718) produced more than 850 turboshaft engines.
