Pratt & Whitney vice president and general manager Eileen Drake said the APS2600[E] APU provides increased electric power capabilities, both on the ground and in flight.
In addition to the APS2600[E] APU, Pratt & Whitney’s AeroPower APUs have been installed in Embraer’s ERJ-145, E170/175 and E190/195 jets.
Recently, Pratt & Whitney AeroPower was also selected for Embraer’s KC-390 military cargo tanker for the Brazilian Air Force.
APUs provide an aircraft with secondary power in the form of high-pressure air for starting main engine, cabin air conditioning, electric power while on the ground, as well as backup electric power during in-flight operations.

By GlobalDataScheduled to enter service in 2018, Embraer second generation E-Jets will be powered with Pratt & Whitney’s PurePower PW1700G and PW1900G engines, which will offer significant reductions in fuel burn, emissions, noise and operating costs compared with other aeroplanes.
Meanwhile, Embraer has selected US-based UTC Aerospace Systems to provide the electric power generation and distribution system for the second generation of E-Jets.
UTC Aerospace Systems will supply the main and auxiliary electric power generators; main and secondary electric power distribution; emergency electric generation system; batteries and converters.
It will also provide the main wheel, nose wheel and carbon brakes through its wheels and brakes division.
Embraer has already selected Pratt & Whitney as the powerplant supplier and Honeywell for its Primus Epic 2 integrated avionics system.
More than 900 current generation E-Jets are in service, with 62 operators from 42 countries currently operating or set to take delivery.
