ROW/ROPS Flashcards
What is ROPS/ROW/ROP?
ROPS: Runway overrun prevention system - ROPS is made up of two sub-functions, ROW and ROP function generates alerts which incite 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: the 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: the ROP function provides enhanced flight crew awareness about the deceleration and capacity to stop before the end of the runway
In aircraft equipped with ROPS, when might you get a ROW 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 the LDA:
The amber “RWY TOO SHORT” message is displayed on both PFD’s. This message flashes for 9 seconds and then remains steady. This message is not associated to an aural alert.
Below 200 ft, If the computations for landing distance is more than the LDA:
The red “RWY TOO SHORT” message is displayed on both PFD’s. This message flashes for 9 seconds and then remains steady. In addition, the following repetitive aural alert triggers: “RWY TOO SHORT”
When does the ROP trigger visual and aural alerts?
On the ground, the ROP function computes the braking distance for the current aircraft and 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 both PFD’s. They flash for 9 seconds and then remain steady.
