A/THR engagement is confirmed when A/THR is displayed in _____ in the right column of the FMA.
Can the engines be overboosted in the TOGA position?
If fuel flow data is lost for more than _____, the last two digits are dashed.

Is there any mechanical linkage between the thrust levers and the engines?
You are in the middle of a manual engine start. What are you looking for when you select ENG MASTER 2 ON?
There is no reverse idle detent. When the pilot moves the lever out of the idle stop by pulling up the reverse lever on the front of the thrust lever, he selects reverse idle.
The A/THR is armed on the ground provided at least one FD (Flight Director) is on by:
Does the FADEC provide EGT limit protection constantly?
![](https://www.smartcockpit.com/wp-content/uploads/2024/05/A320-Engine-Instruments.jpg)
If a throttle is set between two detents, the FADEC selects the rating limit:
The FADEC prevents the thrust from exceeding the limit for the thrust lever position in automatic mode only.
The FADEC prevents the thrust from exceeding the limit for the thrust lever position in both manual and automatic modes.
The FADEC will automatically abort an abnormal start thereby providing engine limit protection, but will the FADEC also automatically dry crank the engine?
Thrust reduction must not exceed 25 % of the full rated takeoff thrust. To meet this requirement, the flexible temperature must not be higher than ISA +60 °C(T MAX FLEX).

The FADEC manages ____ idle modes.
What would happen during the takeoff roll if the thrust levers were set to the FLX/MCT detent without FLEX temperature being entered?
In normal operation, autothrust is available when the thrust levers are in the range between the idle stop and CLB detent.
Using manual thrust, the thrust lever position will determine the thrust setting for the engine.
Oil pressure and temperature are monitored upstream of the oil filter.
Oil pressure and temperature are monitored downstream of the oil filter.
