(2023) Service Advisory 23116 Rev A: ATR (Automatic Thrust Reserve)

PRODUCTS AFFECTED:

G1000 NXi Integrated Flight Deck with system software versions 03643.00 thru 03643.06 installed in Embraer S.A. Models EMB-500 and EMB-505 Phenom aircraft using AML STC SA01933WI are affected.


ISSUE:

While on the ground and ATR set to OFF, ATR may revert to ON.

NOTE
Once the system reverts ATR to ON, it cannot be changed to OFF.

NOTE
ATR ON provides a more conservative FADEC (Full Authority Digital Engine Control) response.


ACTION:

Before takeoff verify the ATR indication at the top of the EIS display for current ATR operating mode.

Refer to the Embraer S.A. Pilot’s Operating Handbook and Airplane Flight Manual for details on ATR.


RESOLUTION:

This issue will be fixed in a later software update (expected Q4 of 2024).
