Sukhoi Superjet 100, SN95003, has successfully completed the test program aimed at evaluation of engine protection against water jets from the runway. The tests confirmed that APU and propulsion system sustain normal operation while running over the wet runway within the full range of modes preceding the take off. So, SSJ 100 is able to carry out safe take-off and landing on runways, covered with water. The tests were conducted in Zhukovsky-based Sukhoi Civil Aircraft Company Flight test center. A special 70m long, pool was constructed on the runway. The pool was filled with water, the depth of the water coverage reached 40 mm.
The aircraft accomplished a total of 27 runs at speed ranging between 10 kt/h and 150 kt/h at different engine modes, special attention was paid to low speed modes, take-off mode and maximum thrust reverser. The tests were monitored by Russian Certification Authorities experts. In order to assess the results the pilots controlled the engines
