I don’t see a way of seeing the ETA of your flight would be good if there were a clock so that one could see the Estimated Time Of Arrival.
There is an ETE I believe for the each waypoint, I don’t know if there is an ETA for arrival at an airport on default a320neo. Also don’t believe the clocks or chronos work.
It’s not implemented/modeled on the default A320Neo in MSFS.
If you were to download the FBW A32NX mod, the DEV or Custom versions have an ETA for every waypoint including the destinations which is updated as the flight progresses.
This is basic flight information that should be included on the MSFS default stock A320 though.
Agree with @AlphaMA1. At the bottom of the F-PLN page is a readout which shows you destination, time (to destination), distance, and estimated fuel on board (EFOB).
A great source of reference on what you should be seeing in the A320 can be found here: http://a320dp.com/A320_DP/nav-flight-management/sys-14.8.0.html
You can navigate around this site using the “next section” “previous section” links on the right or hit INDEX at the top of the page. You cannot go to this source directly.
In the default A320 if you press the F-PLN button and scroll up/down with the panel arrow keys you can see the waypoint / destination arrival times in UTC. In the above screenshot the plane has an ETA in Sydney (YSSY) runway 25 at 8:30a UTC with the current time as 1:45a UTC, so just under 7 hours.
For real-time weather the plane’s clock is usually within a few seconds of my computer’s clock. During the flight, the destination time can change a bit based on airspeed but it is fairly accurate except for flights over the poles which seems to be a bug.
The waypoint times in UTC are also usually close - in the screenshot the next waypoint 07N70 has an ETA of 2:00a UTC which is reasonably correct considering a distance of 126 NM and a speed of 498 knots (basic math - 126 / 498 * 60 = 15.18 minutes ~ 15m 11s).
I’m wondering what does the 26:00 mean under the 126.2NM in the navigation display? Shouldn’t that instead be 15:00 because the plane is about 15 minutes from that next waypoint?
