ATR electronic checklist inaccuracies

ISSUE DESCRIPTION

The following things are incorrectly modelled:

  • When starting up the aircraft the EWD should not show any faults unless RCL is pressed. On battery power, the procedure menu is displayed, when establishing DC power (GPU or hotel mode), the fault list (left side) is blank and only some procedures are shown. On battery power most alerts are inactive (only warnings would appear), so even when pressing RCL, nothing will be displayed. On GPU, pressing RCL should display faults in the fault list and the remainder of the procedures.
  • Pressing RCL while in a procedure, should close the procedure and go back to the PROCEDURE MENU.

FREQUENCY OF ISSUE

Always.

REPRODUCTION STEPS

  • Power up the aircraft (batteries first), and observe active faults in the faults list and active procedures displayed. Fault list (left side) should be empty and no procedures should be shown, should only show: NO ACTIVE PROCEDURE and procedure LIST.
  • Now select DC GPU, observe the active faults in the fault list still displayed and getting shorter and all active procedures shown. It should not be showing any faults in the fault list (left side) and only the following procedures:
  1. ACW GEN 1+2 LOSS
  2. PACK 1+2 FAULT
  3. BLEED VALVE 1 FAULT
  4. BLEED VALVE 2 FAULT
  • The fault list should only populate (flashing until Master Caution is pressed) when pressing RCL button. The fault list in cold and dark state is also way too short (and not in the right order), it should barely fit on one page, open DOORS or non-standard alerts would push faults to a second page, the faults missing for cold & dark state are:
  1. OXY
  2. FUEL FEED LO PR (2 times)
  3. ACW GEN 1
  4. ACW GEN 2
  5. A-ICING BLEED
  6. A-ICING DETECT
  7. A-ICING L WSHLD
  8. A-ICING R WSHLD
  9. A-ICING PIT CPT
  10. A-ICING PIT F/O
  11. A-ICING PIT SBY
  • Not sure if cycling between pages with RCL is implemented. I’m not even sure that it is possible to show sufficient faults to push a second page.
  • Now open any checklist, press RCL and observe the checklist isn’t closed, the ECL is not returning to the PROCEDURE MENU.

YOUR SETTINGS

Not relevant.

MEDIA

EWD during power-up on battery power, fault list (left) blank (even after RCL):

EWD after selecting GPU ON, only some procedures are shown, fault list is blank. Oxygen is a new fault in this example that appeared after power-up:

Upon pressing RCL, all hidden faults and procedures appear, all the faults that weren’t there prior pressing RCL should flash in amber until pressing Master Caution. Not all faults fit on the alert list (left side) indicated by the amber arrow:

Pressing CLR would hide all active faults and procedures with a “PROCEDURE PENDING” message to indicate that stuff is hidden:

Pressing RCL, would again show all hidden faults and procedures (not flashing this times, we have already seen them before). Amber arrow indicates that not all faults can be displayed:

Pressing RCL again shows the second page of the fault list if not all faults can be displayed on one page. Repeatedly pressing RCL keeps cycling between the two pages:

Asobo ATR on battery power:

Asobo ATR on GPU:

To add to this, when clearing the EWD (CLR), upon a new fault triggering, only that fault should be displayed on the EWD. Currently it seems that any new fault after CLR causes a RCL of all the faults.
