Note: The STOP bar moves along the runway as the braking distance is computed in real time according to the current flight parameters.
5.6.3.4. ROP INDICATIONS WHEN ENGAGED
When ROP detects a runway end overrun, it:
-
Displays the computed braking distance in red on ND
-
Displays the red message MAX REVERSE on PFD. Refer to Figure 5-30 and Figure 5-31.
MAX REVERSE or KEEP MAX REVERSE
ROP triggers the aural alert:
-MAX REVERSE continuously until the complete deployment of reversers, or
- KEEP MAX REVERSE one time: .. At 80 kt if the flight crew fully deployed the reversers and ROP still detects a runway end overrun, or
.. Below 80 kt if the flight crew fully deploys the reversers below 80 kt and ROP still detects a runway end overrun.
Figure 5-31: PFD – ROP engaged
5.6.4. INDICATIONS FOR AUTO BRAKE DISCONNECTION
When the flight crew deliberately disconnects the auto brake (i.e. press two times on the A/THR instinctive disconnect pushbutton), there is no indication in the cockpit.
When the auto brake is inadvertently or automatically disconnected, aural and visual indications are provided.
In addition, all ROW, ROP and BTV indications are removed from display.
5.6.5. ROW/ROP CONTROLS
5.6.5.1. RUNWAY SHIFT
The flight crew inserts runway shifts via the OANS MAP DATA page (Figure 5-33 to Figure 5-35). The flight crew can insert runway shifts for one runway only at a time. Used unit (m or ft) is defined by pin-programming.
Note: Runway shifts are not erased at the end of the flight. They remain active for the next flight unless the next flight crew deletes them.
5.7. OPERATIONAL RECOMMENDATIONS FOR ROW/ROP
5.7.1. FOR THE AIRLINE
. Train your flight crews to properly operate ROW and ROP. Particular attention should be paid to task sharing, monitoring of ROW/ROP indications during approach.
5.7.2. FOR THE FLIGHT CREW
.
Be sure to understand ROW and ROP indications. The DRY and WET lines and the STOP bar move along the runway according to the current flight conditions. Overrun situations can be anticipated thanks to these indications.
.
Monitoring of the DRY and WET lines under 500 ft is at PNF’s discretion. PNF should concentrate on basic flying parameters.
.
Use the A/THR instinctive disconnect pushbutton on the thrust levers to disconnect the auto brake.
5.8. REGULATIONS FOR ROW/ROP
At the time of writing the present brochure, there is no mandate for the carriage of the ROW/ROP function.
5.9. MANUFACTURERS FOR ROW/ROP/BTV
AIRBUS developed ROW and ROP that are distributed among several systems. They are optional functions and are simultaneously activated via pin-programming.
