Remember we were never at MTOW for long in this machine! Initial subsonic cruise ex-LHR was 280-300. In the case of engine failure enroute, it usually ended up in the mid-30's (with its subsonic 4 engined contemporaries). The process explained in the extract from the OM is worth thinking about...you fly Mach, but the IAS still plays a dominant role on drag as you climb. Most unlike conventional types.

Someone I used to know,(TO), was a F/O on a Concorde that had a double engine failure mid Atlantic. One engine surged and coughed an inlet door out of the front and it went down the adjacent engine, The vibration was very high and both engines were shut down. The Mayday call to Shanwick was that they may not make Shannon. The reply was that they would alert the coastguard.
IIRC they restarted the engine with the lowest vibration and made it to Shannon. I saw some photos of the engine that ate the door and the compressor was a mess. Reply to this quoting this original post. You need to be logged in. Not available on closed threads. |
