Flight Testing of E195-E2 Aircraft with 100 per cent SAF Completed

Issue: 4 / 2022

Pratt & Whitney and Embraer have successfully tested a GTF-powered E195-E2 aircraft on 100 per cent Sustainable Aviation Fuel (SAF). The test, with one engine running on 100 per cent SAF, validated that GTF engines and the E-Jets E2 family can fly on both engines with blends of up to 100 per cent SAF without any compromise to safety or performance. The aircraft completed two days of ground tests at Fort Lauderdale International Airport, culminating in a 70-minute flight test at Vero Beach Regional Airport in Florida.

All Pratt & Whitney engines and Embraer aircraft are currently certified to operate with SAF blended up to 50 per cent with standard Jet A/A1 kerosene, according to ASTM International specifications. Future specifications will enable blends of up to 100 per cent SAF to maximise the emissions reduction potential of using fuel derived from sustainable, non-fossil-based feedstocks.

The SAF used by Embraer and Pratt & Whitney was 100 per cent Hydroprocessed Esters and Fatty Acids Synthetic Paraffinic Kerosine (HEFA-SPK) acquired from World Energy. HEFA-SPK is a specific type of hydrotreated renewable feedstock fuel used in aviation and is considered a leading alternative replacement for conventional jet fuel by the Commercial Aviation Alternative Fuels Initiative (CAAFI), due to the sustainability of its feedstock.

The P&W GTF engine is the only geared propulsion system delivering industry-leading sustainability benefits and world-class operating costs. It is the exclusive powerplant of the Embraer E-Jets E2 family.
