However 'Max. takeoff rating' is for some reason not defined in the Flight Manual (not in mine anyway). So extra power is available for the purpose of taking off, but cannot be used continuously. So just how long does 'taking off' take? Presumably, the VEMD will log any exceedance of 'Max. takeoff' power, so it presumably has an in-built time limit. The question is how long is it?

Cursory glances at the airframe & engine maintenance manuals reveal no time limit for Q and Ng. Maintenance inspection/procedures are required after 5 minutes for T4. VEMD recording parameters are in the manual also. Don’t take my word for it.
