and I don't expect to get them from pilots who haven't planned a trip in an airliner, as dispatch does that.
And who do you think teaches Dispatchers what ETOPS is all about? Who do you think gives Jeppesen the fuel figures for that particular aircraft? Who do you think actually decides on the fuel policies to comply with the regulations........
Even in our part 91 aircraft we know what the fuel flow is at 10,000 feet, together with the ETOPS points, diversion airports and distances...... not required by regulation, but nice to have
As for our corporate aircraft, we do not consider continuing at altitude following a depressurization regardless of the amount of oxygen that we have onboard.
