ROW/ROPS, RAAS
 
hello everyone

my company just announced that our future 320 deliveries will include ROW, RAAS and a few more additional features.
I was looking for a system description in the fcom and FCtM.
I could only find a paragraph in the FCtM and a safety newsletter.
Can somebody help me finding the fcom reference?
thanks in advance.

Ok I finally found row ROPS in dsc 34-75-10
i still need help for RAAS. ,
thanks

And I found RAAS as well. Dsc 34-70-40

if somebody knows where to find more info, feel free to share. Thank you

Basically RAAS tells you which runway you’re on and ROPS will try to prevent you from overrunning one by applying brakes or telling you to go around.

Thank you .I had already read about it and even used raas at my previous airline but I needed the fcom references. Turns out the systems are no described in my company manual, I assume because we don't have them installed yet... I found them in my generic Airbus fcom .

ROPS won't brake for you (unless you're flying the 380 or 350). It's a PFD flag / chime, and auto-callout.

Thanks for clarifying. Thought it can be retrofitted onto the 320 with all features.

Honeywell:
Runway Awareness and Alerting System (RAAS) has been added to the Airbus catalog as a product available for all Airbus aircraft.
RAAS is a software enhancement to Honeywell’s Enhanced Ground Proximity Warning System (EGPWS) that uses the EGPWS computer and runway data base to provide pilots with audible warnings if they are taxiing onto an active runway unintentionally.

Basically a scaled down version of SmartRunway/SmartLanding...additional features usually found in these are provided by ROPS+.

NAVBLUE:
ROPS+ continuously monitors the aircraft’s position with respect to the remaining runway length and calculates whether the aircraft can safely come to a stop. ROPS+ alerts are designed to effectively guide and assist the crew in the go-around decision-making process or, when on ground, the timely application of deceleration means.

ROPS+ key features:
  • Automatically detects the landing runway and updates in case of late change of runway
  • Continuously monitors the aircraft speed and height during the landing phase
  • Updates the calculation of stopping distance 8 times per second based on real-time conditions
  • In-Air – generates alerts to warn the flight crew of overrun risk and aid in go-around decision
  • On-Ground – if overrun risk exists, generates alerts to solicit flight crew to use all available deceleration means

Have a think about what you'd do if it calls "Long Landing" when you're about to touch down 1000m in on a 4000m runway...:}

Yeah, I am not overly impressed by RAAS. Another thing the office/engineer guys thought it is a "safe" and "cool" tool.Another voice in the cockpit. It makes you write more reports(at least in my outfit), especially going with green 500 hour guys into european "standard" runways(so more or less anything between 2400 - 3500m) and instead of the usual carrier landing for cable #3 they pull just a tad to much and it ends into a bit longer flare....no big deal. But RAAS DOES NOT like it.

But more then once the RAAS came up AFTER touchdown....(737NG)

IMHO just another "spying" tool on pilots(data monitoring + event), forcing them to write even more reports or sit the thing down with smoking tires(Treviso is the place for that, or Crotone, lol, there must be already a hole in the TDZ). Next will be cockpit cameras.... had to be very diplomatic on my last DH as one pax asked me after landing "how comes that the landings in your company are always that hard?"...... I said - "safety sir, safety"(or maybe lack of common sense?). Everyone is scared to flare nowadays :E RAAS is contributing now to that.


If I think back to the "old good times" with tower instructions like "cleared to land , DO LONG LANDING, vacate via the end" and we did that. And we COULD. Or Rwy 28 in Zuerich - LAHSO - Land and hold short operation with simultanuous landing rwy 16 and 28, landing traffic on 28 had to hold short of runway 16(not to mention the non precision approach on Rwy 28). No big deal. Anyway - long gone. NOW we have RAAS to tell us how to land a plane. Fantastic new aviation. Hope they invent the "drone plane" soon, so it does all the things they deem safe(including a software induced deep dive for "landing"). Not far from retirement, so, do what you want(for sure I will never step a foot in a robo plane, my god, this will be hard lesson to learn when they will decide to move it to that level).

For ROPS, if you're going to vacate the runway at it's end, you'll have to slow to about 15 kt ground speed.
Otherwise it will shout at you all the way to the gate.
