Does UPS have driftdown charts in the QRH or do they have supplemental charts for that printed separately?
We have drift down charts but by selection ENG OUT on the FMS the FMS calculates the drift down altitude automatically. Just select the nearest altitude in the Altitude window (MCP) and the jet will maintain your current altitude until it begins to sacrifice speed. At that point the aircraft begins a shallow drift down the the new altitude. Easy peasy.
