Regarding the news on Airbus’s Runway Overrun Prevention System (ROPS), the ROPS application for the A330 series aircraft has recently successfully obtained airworthiness certification from the European Aviation Safety Agency (EASA). 空客ROPS应用于A330获认证，ROPS覆盖空客全机型 A330のオーバーラン防止装置、EASAが認可

Here is a summary of the ROPS data. As explained in the article from the China Civil Aviation Network above, ROPS is essentially an alert system. It helps improve pilots’ situational awareness during landing, reduces the risk of aircraft overrunning the runway, and in necessary situations, the system can provide active protection for the aircraft. From now on, all Airbus aircraft models can have ROPS installed upon delivery, and all in-service Airbus aircraft can also be modified to install ROPS.

Runway excursion refers to an aircraft veering off the side or running off the end of the runway, and it has long been one of the main causes of civil aviation accidents.

The patented Airbus Runway Overrun Prevention System has successfully obtained airworthiness certification from EASA, FAA, and CAAC. It can calculate the minimum airborne landing distance and ground braking distance during landing, and performs real-time comparison between the calculated data and the actual conditions of the airport runway. The system’s database not only covers weather factors, runway conditions, and terrain, but also includes aspects such as aircraft weight and configuration.

Through computer analysis, the Airbus Runway Overrun Prevention System can issue emergency voice prompts and alerts to the crew under different circumstances, thereby assisting the crew in making the correct choice during the decision-making process of whether to go around, or helping the crew quickly apply stopping devices during the landing process.

Looking at another Airbus document, Runway Overrun Prevention System ROPS = ROW + ROP ROW: Runway Overrun Warning ROP: Runway Overrun Protection

For example, in wet runway conditions, if the Runway Overrun Warning distance is greater than the remaining runway length, and the aircraft altitude is below 400 feet, ROPS will display an amber warning message on the PFD, which will flash for 9 seconds.

In dry runway conditions, if the Runway Overrun Warning distance is greater than the remaining runway length, and the aircraft altitude is below 400 feet, ROPS will display a red flashing alert on the PFD for 9 seconds; when the altitude is below 200 feet, an emergency voice prompt “RWY TOO SHORT” will be issued.

If the Runway Overrun Protection distance is greater than the remaining runway length, a red alert message can be seen on the PFD, and continuous voice prompts “BRAKE… MAX BRAKING” and “SET MAX REVERSE” will be issued, reminding the pilots to use maximum braking and reverse thrust; after the speed is below 80 knots, if the runway length is still insufficient, an additional “KEEP MAX REVERSE” voice prompt will be issued, reminding the pilots to maintain maximum reverse thrust.
