A320 NEO autopilot help

[2 yil]

So i've been at it for 2 days now, I really don't understand how the AP on the a320 works, i have no problem with the AP following my flight plan, but i can't manually change the speed, altitude or VS with the knobs on the AP board. I tried searching for tutorials and none of them have really been helpful..

Anyone got any tips?

I'm having the same problem on the 747. I can change the knobs and set it ok but the plane just does not listen to the settings I have. It keeps going up and down in altitude and nothing I do changes that.

Says something about Air speed being above 250 knots.

I have the same problem, so I can't help you

If it doesn't like you maintaining 250 knots, then your gears and/or flaps arent retracted.

You need to turn on A/THR switch on the left side of the panel and one autopilot. If you want it to control speed, SPD button has to be active. If you want it to hold altitude, HOLD under altitude knob has to be active. If you want it to control heading, HOLD under heading has to be active.

To reach certain altitude you either turn FLC mode on or turn on V/S mode and adjust the vertical speed you are comfortable with. After reaching desired altitude AP will turn off FLC or V/S modes and turn on HOLD altitude mode.

If you want your plane to follow the course or altitude from MFDCDU, LNAV or VNAV should be on respectively. These settings replace FLC mode.

To disengage autopilot you need to press the rectangle under three autopilot buttons and turn off A/THR.

Here you go

The autopilot in the A320 is quite different from the Airbus in FSX and from a Boeing here, and kinda slow executing your commands. You can set hdg, speed and altitude using the knobs but every time you need to clic on them, they have 2 clic areas: one on the upper part (your mouse will become an up arrow) and one on the lower part (down arrow) of the knob, if you hold your mouse on it you'll see two different descriptions because they are two different modes. You need to clic on the lower one and it will take a few seconds for the plane to execute what you want but it works. The upper part basically tells the plane "Do what you want with this".

AP1 on, A/THR on. Throttles have to be in A/THR position as well. To make AP follow your settings you need them to be visible on the screen and in manual mode. If there is a dot to the right of the number than this setting in managed mode. It takes speed and altitude from CDU and heading from your flight plan. Sometimes you can see a number, but there is still a dot to the right of it, it means that while you can see your manual settings, they are not used and the plane still follows the flight plan and CDU instructions. To engage manual settings you need to pull the related knob (move your cursor slightly under the knob, cursor should turn into an arrow pointing downwards). To engage managed mode you need to push the knob (cursor looks like an upwards arrow).

Few things to consider

When you adjust your speed setting, it takes time for AP to understand it and start to correct the speed. like 30 seconds or so. I think this is not how it supposed to work. If it still acts strange turn off and on A/THR button. If you change desired altitude, pull the knob after that. Only then it will apply the change of desired altitude instead of speed and heading adjusting immediately.

Altitude in managed mode still can follow the number on the screen, but it should respect altitudes in the flight plan. Not sure about that, but thats how it was in other sim I've played. Also managed altitude there used to set speed to managed as well.

Also Im not sure how Veritcal Speeds works on A320 in this sim. You pull the knob as usual and you can adjust the vertical speed just like heading or usual speed. Vertical Speed overrides usual Speed in order to maintain the desired vertical speed. So, in that other sim it also worked differently. Here the number disappears after you pull the knob. It still aplies, you can see it on your PFD (main screen with red ground and blue sky, horizon etc) above. But Im not sure if it works at all.

So, there are problems here and there. But apart from Vertical Speed you can adjust your autopilot manually just fine

This guy does some pretty good Airbus tutorials, also has ils and flight computer ones too.
