Why are we bothering with engine start? 'Gravity feed' limitations normally refer to high power settings, not idle.
For the benefit of the rest of us, what caused all this chat? Did an AB flame out? Any report? |
Engines can be started and take off can be performed with fuel pumps off. Hence the FWCs were modified so that they can monitor fuel pumps (along with hyd pumps and system pressure, generators and IDG disconnection) and trigger a caution when Take off config test is performed.

As this thread has a high count of numbers from the book, but is short on reasons why, may I throw in some information I gleaned 'hands on' from testing fuel systems both for a fuel gauging manufacturer and an airframe manufacturer.

BOAC. There were no flame out. Just a thread started regarding gravity fuel feeding. The beginning of the thread would explain the question.

MECHTA. Thanks for your input.
