Pratt & Whitney AeroPower's APS2600[E] auxiliary power unit (APU) has been selected by Embraer for its second generation E-Jet. APU...
APUs provide aircraft with secondary power in the form of high pressure air for main engine starting, cabin air conditioning and electric power while on the ground. APUs can also provide backup electric power during in-flight operation.
In addition to the APS2600[E] APU, Pratt & Whitney AeroPower APUs can be found on Embraer's ERJ-145, E170/175 and E190/195 fleets.
Pratt & Whitney AeroPower APU was also recently selected for Embraer's KC-390 military cargo tanker for the Brazilian Air Force.
The second generation Embraer E-Jets will also be equipped with Pratt & Whitney's PurePower® PW1700G and PW1900G engines, which will offer significant reductions in fuel burn, emissions, noise and operating costs compared to today's aircraft.
