FCTM Thrust Control
Warnings And Messages
There are a number of warnings, cautions and messages associated with the operation of the A/THR. The warnings, cautions and messages can be classified as follows:
.
Take-off
.
All Engines Operative
.
One Engine Inoperative
.
Disconnection
.
Protection
Take-off
The three thrust setting options available for take-off are Flexible Thrust (FLX), Derated Thrust (DRT) and Take-off and Go-around Thrust (TOGA). The corresponding thrust lever quadrant detents are FLX/MCT for FLX and DRT take-offs and TOGA for TOGA take-offs. The FLX temperature and DRT level are entered via the MCDU. The ECAM provides an element of protection against the use of incorrect thrust settings for take-off by generating the warning "ENG THR LEVERS NOT SET" if the thrust levers position disagrees with the MCDU input. The corrective action for this warning is different depending on the situation. All CX aircraft have the DRT function enabled and the situations that will generate this warning are:
.
If no FLX temperature or DRT level has been inserted and the thrust levers are set to the FLX/MCT detent
.
If a DRT level has been inserted and the thrust levers are set beyond the FLX/MCT detent
.
Thrust levers are set to below FLX/MCT detent.

All.Engines.Operative
With the A/THR active, if one of the thrust levers is set below the climb detent, the message "LVR ASYM" is displayed in amber on the FMA. In this case, each engine will be limited to its appropriate TLA position. This allows the continued use of autothrust if one engine has to be RPM limited for an operational reason,
e.g. excessive vibration.
With the A/THR active, if all thrust levers are set below the CL detent, the warning "AUTO FLT A/THR LIMITED" appears on the E/WD and the message "LVR CLB" flashes in white on the FMA. This situation is brought to the crew's attention as a caution, with a single chime repeated every 5 secs until the thrust levers are returned to the CLB detent or the A/THR is disconnected. There should be no operational requirement for the pilot to limit A/THR authority on all engines.
With the A/THR active, if all thrust levers are set above CL detent, the message "LVR CLB" flashes in white on the FMA beneath the boxed "MAN THR" message. The engine power will increase to the thrust corresponding to the TLA.
One.Engine.Inoperative
With the A/THR active, if the thrust lever(s) of the remaining engine(s) are set below the MCT detent, the caution "AUTO FLT A/THR LIMITED" appears on the E/WD and the message "LVR MCT" flashes in white on the FMA.

DISCONNECTION
Intentional A/THR disconnection is accomplished by:
.
Depressing the instinctive disconnect pb
.
Setting all thrust levers to IDLE
The normal method of disconnecting the A/THR is through the instinctive disconnect pb on the thrust levers. The PF should announce his intention to disconnect the A/THR and then use the following sequence: 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址:A330/A340 机组训练手册 FCTM Flight Crew Training Manual(16)
