No, it won't. I mean if the automatics can't make an RTA because even by flying at green dot etc. it's not achievable, then descend or whatever is required.
But in several years of flying the 'Bus, this whole idea of not going near green dot because it's dangerous, is just plain wrong
. Sure, in turbulence, give yourself a bit more margin. But smooth air, really?
It's just like those who want to throw a few extra knots onto the VAPP when the autothrust is doing a brilliant job of maintaining VLS+5. You already have a margin, it's called that +5kts that Airbus allows for the autothrust. Even more questionable when the landing distance check they performed just before descent shows a margin of stuff all, and they want to throw some more speed on and now make it an unknown landing distance.
Sounds typically Australian, to re-invent the wheel rather than just letting the aircraft do what the manufacturers designed it to do, with plenty of fat already built into it.
