AUTOFLIGHT MENU Disconnection operation 13/26 Note that: - on PFD2, the FD crossbars are removed , - on both FMAs, FD engagement indication is removed as well as all AP/FD modes. It is important to notice that if both FDs are set to OFF while AP is OFF, A/THR (if active) is automatically in SPEED mode. Note: it is recommended to set both FDs OFF at the same time.

AUTOFLIGHT MENU Disconnection operation 17/26 You have now manual control of the thrust with the thrust levers. Since the levers are in CLB detent, the thrust increases to CLB thrust. As a consequence, the a/c accelerates; this is in most cases quite undesirable: in approach, for example, this will destabilize it. We will see now the standard A/THR disconnect technique. AUTOFLIGHT MENU Disconnection operation 18/26 The standard A/THR disconnect technique is: First, retard the thrust levers to the position corresponding to the current thrust, using the N1/EPR engine thrust indications on the E/WD. Clliicckk oonn tthhee tthhrruusstt lleevveerrss You are back with AP/FD OFF and A/THR ON in SPEED mode. You wish to set the A/THR OFF, minimizing the thrust change.

AUTOFLIGHT MENU Disconnection operation 24/26 When the A/THR is turned OFF, you get the following temporary warnings: - single chime, - Master Caution illuminated during 3 s, - on E/WD, “A/THR OFF” amber message for 9 s. You have now manual control of the thrust and there is hardly no thrust change since thrust levers were set by you at the right position. Note: If you press the instinctive disconnect pb again, you will cancel all these cautions immediately. AUTOFLIGHT MENU Disconnection operation 25/26 When A/THR is ON and if you retard the thrust levers too slowly or inadvertently below the CLB detent, you will get the following repetitive caution every 5 s: - single chime, - Master Caution, - “AUTO FLT A/THR LIMITED” amber message on E/WD. AUTOFLIGHT Disconnection operation 26/26 This caution advises you that the thrust lever position limits the maximum thrust for the A/THR. LVR CLB on FMA and the ECAM caution on the E/WD recommend that you bring back the thrust levers into the CLB gate. Note: by setting the thrust levers into the CLB detent, you will cancel all the cautions immediately.
