December 9, 20178 yr Bonjour, May be someone can give me a clue ! Is the bleed air provided by one engine running is enough to start the other ? It does not seem possible. I always have to start the APU, to give me more bleed air to start the second engine. Merci Claude Claude Troncy
December 9, 20178 yr Hello, If you perform a cross bleed start (starting an engine with the bleed air from the other engine), you have to increase a little the rpm of the running engine to get at least 30psi for the engine start. (I usually find that 28-30% N1 is enough to get the correct pressure) Check also that the isolation valve is set to open and both packs are off.

Just by increase N1, on the engine running, solve my problem. Cheers Claude Claude Troncy
