ROW/ROPS Flashcards
What is ROPS/ROW/ROP?
ROPS: Runway Overrun Prevention System
The ROW function generates alerts which indicate the flight crew to perform a Go-Around whereas the ROP function generates alerts which incite the flight crew to apply available deceleration means.
ROW: Runway Overrun Warning
ROW function: provides enhanced flight crew awareness about the approach stabilization and the capacity to land on available landing distance.
ROP: Runway Overrun Protection
ROP function: provides enhanced flight crew awareness about the deceleration and capacity to stop before the end of the runway.
In aircraft with ROPS, when might you get amber RWY TOO SHORT vs a Red RWY TOO SHORT message on the PFD?
Below 400 ft, if the computation for landing distance is more than LDA:
*the amber RWY TOO SHORT message is displayed on both PFDs. This message flashes for 9s and then remains steady. This message is not associated to an aural alert.
Below 200ft, if the computation for landing distance is more than the LDA:
*the red RWY TOO SHORT message is displayed on both PFDs. This message flashes 9s and then remains steady. In addition, the following repetitive aural alert triggers: RUNWAY TOO SHORT.
When does the ROP trigger visual and aural alerts?
On ground, the ROP function computes the braking distance for the current aircraft and the runway conditions. If current braking performance is not sufficient to stop on LDA, it triggers visual and aural alerts.
What happens if an overrun situation is detected?
As soon as an overrun situation is detected MAX BRAKING and MAX REVERSE messages are displayed on the both PFDs. They flash for 9s and then remain steady.
