Pressing the A/THR instinctive disconnect pushbutton on the thrust levers, or
- Switching the auto brake mode selector to DISARM.
Pressing the A/THR instinctive disconnect pushbutton on the thrust levers is a new method to disconnect the auto brake introduced by ROW/ROP/BTV.
The auto brake automatically disconnects when the aircraft reaches:
- 0 kt if the flight crew selected an auto brake mode (except BTV), or
- 10 kts if the flight crew selected BTV.
3 If the ROW/ROP function is lost during the period when ROP is engaged, the auto brake maintains the maximum braking performance.
5.6.3. ROW/ROP INDICATIONS
5.6.3.1. ROW INDICATIONS WHEN ARMED
If the flight crew selected an auto brake mode (except BTV), ROW highlights the runway QFU.
If the flight crew selected BTV, ROW displays the DRY and WET lines in magenta.
Note 1: ROW computes the braking distances in real time. Therefore, the DRY and WET lines move along the runway according to the current flight conditions (Vapp, landing configuration, aircraft position, ground speed, wind, aircraft weight).
Note2: The green triangle refers to the runway selected in the FMS.
5.6.3.2. ROW INDICATIONS WHEN ENGAGED
. Computed braking performances not sufficient in wet conditions On ND
If the flight crew selected an auto brake mode (except BTV), there is no additional ROW indication on ND when ROW engages. Refer to Figure 5-22.
If the flight crew selected BTV, when ROW engages, it displays:
-
The WET bar in amber
-
The path between the runway end and the WET bar in amber.
On PFD
ROW displays an amber message IF WET: RWY TOO SHORT on PFD, regardless of the selected auto brake mode.
. Computed braking performances not sufficient in dry conditions On ND
If the flight crew selected an auto brake mode (except BTV), there is no additional ROW indication on ND when ROW engages. Refer to Figure 5-22.
If the flight crew selected BTV, when ROW engages, it displays:
-
The WET and DRY lines in red
-
The path between the runway end and the WET and DRY lines in red.
On PFD
ROW displays a red message RWY TOO SHORT on PFD, regardless of the selected auto brake mode. In case of wind shear, the red message WINDSHEAR has priority.
RUNWAY TOO SHORT
ROW triggers the aural alert RUNWAY TOO SHORT below 200 ft RA. 中國航空網 m.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：getting to grips with surveillance(87)
