Re: CFM Engine High Oil Consumption

Calculating oil consumption is critical to ETOPs. In order to do so properly, you must assume the oil was serviced properly before. If no oil was added for the prior leg, and was entered as serviced when it wasn’t, then at the end of the next leg, oil would be added for both legs, but the flight tim...

You are very correct, those little things burn up the oil. Much more so compared to the IAE. I don’t have the hi-limit consumption rate on hand, but I’m sure it’s more than a pint per hour. GE engines have always used more oil than competitors. The reason why is the oil scavenge system. They must th...

On a 777, you can access the forward cargo from the E&E compartment, which itself is accessed from a hatch in the floor in the first class galley. To open that hatch you need to be able to unlock it. The 787 has no such access.
