“Honeywell Aerospace ’ s auxiliary power unit, or APU, franchise, which spans these verticals without
equal, does not have quite the same intensity of razor-and-blades aftermarket value as the GE/Pratt/
Rolls oligopoly. Nevertheless, of 52,000 commercial, business, and military jets in service, 32,400 have
Honeywell APUs. Of the total, 14,800 are GTCP131, and 6,550 are GTCP36. Of the 22,000 business jets in
service (large and small), Honeywell Aerospace supplied half of them with its APU, while it supplied
only 3,950 with engines — in either the HTF7000 or TFE731 family. All but one of these also runs a
Honeywell GTCP36 or RE100 APU. Honeywell ’ s largest competitor in business jet engines and APUs”
