The JOEB found only one Special Flight Characteristic; the engine “spool-up” time is longer than most transport category jet aircraft. It can range from 8 seconds at sea level to 30 seconds at altitude to move from idle thrust to maximum continuous thrust. At low altitude e.g. circling, the spool-up time will be considerably longer than 8 seconds if Flaps are -flight briefing, highlighting engine spool-up times, is accomplished prior to conducting training or checking in the following areas: stalls, touch-and-go landings and simulated one-engine inoperative manoeuvres.
Flight crew must be made aware of the risks during a go-around from an LNAV/VNAV approach. The danger is related to the requirement to set an altitude below actual aircraft altitude during the final approach. Until such time as modifications are made so that the altitude selector setting procedures are similar to procedures used during an ILS approach, LNAV/VNAV approaches to a go-around must stress FMA awareness and the requirement to reset the altitude selector, after the go-around has been initiated, to the go-around altitude.
Is this an engine issue ?
