Q:<\/strong>
\nThe meaning of the alert, in my understanding, is notifing crew to set thrust lever to ILDE when needed.<\/p>\n

However, the triggering phases includes 8 and 9. If in eng stall or manual flight, crew set one lever at IDLE intentionally, the triggering condition shows this alert will appear. Will it make confusion to crew? It sounds like “oh, you should set another lever to IDLE too”.<\/p>\n

A:<\/strong>
\nENG 1(2) THR LEVER ABOVE IDLE is triggered on the ground (normally during T.O or Landing roll above 40 KTS) if one THR LVR is above idle and the other THR LVR is in REV detent or the other THR LVR is at IDLE, the crew SHALL SET affect LVR to IDLE and follow the SOP for landing.<\/p>\n

Q_2:<\/strong>
\nThe “Flight Phase Inhinition” shows this alert can be trigger in phase 8 & 9 which are not on ground. For example, in case of ENG STALL on simulator, we can set one thrust lever at IDLE, and another one at MCT or CLB (above IDLE). Although this case already conform the triggering conditoin, we never saw it triggered.<\/p>\n

There’re 2 cases of one lever at IDLE or REV and another above IDLE. Case 1 is we should set both above IDLE, and case 2 is both at IDLE or REV. The alert about these two cases should be the same. However, the triggering condition of ENG 1(2) THR LEVER ABOVE IDLE doesn’t distinguish them.<\/p>\n

A_2:<\/strong>
\nWe confirm that your understanding is correct.<\/p>\n

The purpose of the ECAM ENG 1(2) THR LEVER ABOVE IDLE is indeed to remind the crew that one thrust lever must be set to the IDLE position. As per design, the message (associated with Dual Retard automatic call out) is activated on ground following a rejected Take-off or after landing. As mentioned, the alert can be triggered in flight phases 8 & 9 but only if the aircraft was previously in flight phase 10 (bounce situation).<\/p>\n

Finally, please keep in mind that the Flight Phase Inhibition section in the FCOM provides information to the crew in regards to the flight phases during which the alert is inhibited by logic
\nbut does not necessary indicate that the alert can appear in the other phases.<\/p>\n

In the case of the message ENG 1(2) THR LEVER ABOVE IDLE, multiple conditions (too much complex to be entirely described) may then prevent the apparition of the alert in the \u201callowed flight phases\u201d (aircraft speed, other displayed alerts, etc.).<\/p>\n","protected":false},"excerpt":{"rendered":"
