Airbus dual engine failure - Why no yellow elec. pump on ?
Hello
does anyone have an idea why airbus does not recommend using the yellow electric pump in the dual engine failure scenario after the APU is available ? I’ve seen a perfectly valid suggestion in an annoficial document that recommends switching the yellow electric pump ON after the APU becomes available and setting the PTU off as the load might be too much for the pump to handle . This aids especially in landing allowing flaps to be deployed as well .
