For this rev. of A320 - in Germany we say "verschlimmbessert", means much worser than before.
A short summery of some issues I had during several flights:
- T/O - FlexTemp, Acceleration Altitude do your inputs have any influence? I guess not or better can't see it.
- Climb - who computed 340 kts ? Resulting in overspeed and AP cutoff. And to get the right THR thereafter is a nightmare.
- LNAV and VNAV accuracy still a wish. You have to keep an eye or better both on it. STARS you better compute by yourself, often you get a nice mix or you will simply miss some.
- does anyone ever tried the hold function? Input Inbound course is not possible, the legtime you can change but at the end you have to use "compute". The result is all others than a hold. And computed the AP ignores all and will fly you into the nirvana. Better you do it in the old fashion way.....heading and clock.
- on Approach - on final, all stable, ILS/GS captured eg. - how in the hell I get Alpha Floor? THR goes to max and you climb out like a rocket. I promise, every controller will be chocked too.
- the lateral oscillations on final with correct approach speed until about 500 tf AGL are not normal. Sometimes up to 15 degr. to both sides with a steady headwind of 15 kts?
For the time - the A320 is not really reliable.
I agree with all these things!
In case i only flow this aircraft at a friend of mine, and there was no real airbus feeling.
The autopilot climbed above the calculated cruise speed at FL390 (was about 260kts indicated) and turned off the autopilot, very hard to get it back working in the right way to keep the speed in "CLB thrust" - in this case i was also missing the red "maximum speed indicator" in the PFD which should be displayed, so the pilot knows when he is going to fast with his plane. By now it is only visible when flaps are extended
I also agree with the lateral oscillations on the final, the airplane turn from left to right, even if there is no wind or a steady wind from the front or slightly left or right -> very hard to keep it on the ILS course, always turning the joystick left and right, but not good!
The stranges thing was the "fly by wire" which is not a fly by wire at all.
It is very hard to get the aircraft of the ground if you think it works as it should - felt like flying a Boeing but not like an Airbus.
Keeping the joystick steady to the back to get the nose up and getting climb rates of more then 5000ft/min is not that normal i think. Also on approach it is hard to keep a steady sinkrate to stay on the glideslope (also see above, lateral oscillations).
Also on VOR approaches where every VOR radial + distance from VOR is inserted the plane does not follow these created points, i think it does not even generates these points.
It was flying straight on indicated heading and altitude after passing the FAF and was not following the entered route to intercept the radial for the VOR approach.
Autoland: very odd thing... there was no wind at all but when touching down the left wire exploded/got damaged - normal thing? i dont think so.
In that case i think i dont buy this aircraft right now, have to wait to get more functions to get it better:
- Fly By Wire
- PFD
- autopilot behaviour
- lateral oscillations
