[FIXED INTERNALLY] WP and flight plan symbology on the HSI is drifting again

BarTzi · May 2, 2019

This is an old bug that was previously fixed but seems to have popped up again.

Essentially, the WP icon and flight path between two waypoints will slide across the moving map when your plane moves.

This will sometimes break so much - that the WP icon will not appear at the end of the dashed lines due to a massive drift that happens when the plane flies next to it (see pics and replays below).

You can very easily spot the drift in the track (watch the HSI). Also -observe the location of the WP icon in relation to the dashed line.

Does it also happens in the SA page?

I checked and it does happen in the SA page as well.

Hey, thanks for the report, I was able to replicate in Open Beta, but not on our internal builds so it looks to be fixed already.

HSI any flight plan symbology is drifting on the HSI [Open beta, 8-5-19]

**my bad- title should say: "WP and flight plan symbology is drifting on the HSI"

Sadly, I have to reopen this thread, since the issue is not resolved.

The previous thread was marked as fixed internally and closed (https://forums.eagle.ru/showthread.php?t=240236).

To sum it up:

1. WP symbology and flight plan symbology will drift on the moving map as your plane moves. This is easier to spot when the plane is set to use Magnetic bearing (default settings).

2. When you fly past a waypoint it will occasionally spin together with the waypoint needle - pushing it randomly from the original position

Please watch this video (set it to X2 speed) to have a better understanding of what I'm talking about:

I placed a waypoint near the runway at Batumi. The waypoint symbol appears over the sea at first (wrong location) and Is slowly drifting forward as I fly north. Watch what happens to the waypoint symbol at 0:54 as the WP icon starts drifting south.

I provided a track (which you are more than welcome to watch at X4 or X2 speed), and the mission itself.

Drifting ASL With Wind Using Mk82Y & Mk82XT

Hi, I have noticed what seems like a glitch with Mk82Y and Mk82XT in auto mode (CCRP). The azimuth steering line (ASL) is unsteady and keeps drifting from side to side, even at the last second, making it really hard to make a precise drop.

The problem is present only when there is wind but is pretty annoying even with moderate winds (10 kts). I remember having the same issue a year or two ago in the A-10C.

Regular slick munition Mk 82 does not suffer from this. Only retarded munitions are affected. I saved a bunch of tracks testing in different conditions. Thanks!
