Waypoint offsets with RNG>100nm distance behave as if they are RNG=0nm

[toneo]

In the Harrier you can set waypoint offsets for each waypoint, which is handy when you receive a target as bearing+range from bullseye. I tried to practice this a few days ago and my target was approx. 150nm from the bullseye and 30nm from me. When I looked at the offset point, it was positioned exactly on top of the bullseye waypoint, not on the target as expected.

Is this supposed to be limited to 100nm or something? If that's how it's supposed to behave in the real jet then that's fine but it would be a strange design choice IMO.

Repro steps:

1. Press EHSD, then box DATA, then box BULL
2. Use arrows to select WP1 (or whichever waypoint is your bullseye)
3. Unbox and re-box DATA to exit BULL mode
4. Ensure WP1 is selected.
5. Press WYPT on ODU to change it to WO/S
6. Click BRG, type any bearing on the UFC and press ENT
7. Click RNG, type something over 100 on UFC and press ENT
8. Unbox DATA
9. Box WO/S
10. Box DATA
11. Observe the selected point is directly on top of WP1 instead of being offset by the correct range
12. Change RNG to 100 and observe selected point is correctly 100nm away as expected.
13. Change RNG to 101 and observe selected point is again back on top of WP1.

Track file attached. Not using MT.

I have a few other related observations which might be bugs, or might not, I can raise separate bugs if interested:

• BULL cannot be unboxed by pressing the OSB next to it. Instead you have to unbox DATA.
• If you box WO/S and then box DATA, the EHSD shows the offset in the centre of the screen. It also shows an additional point offset by the same amount, instead of showing the original point.

Values 0-100 are in nautical miles, values >100 are in metres. The UFC will display either "NM" or "M" to show this.

Thanks, that makes a lot of sense! Unfortunately looks like this is hard limited, the distance in metres is also limited to the equivalent of 100nm.

Yes, that is correct AND as in the real aircraft. And if you think about it, where would you have use for an offset(!) of 100NM or more, instead of creating a proper waypoint? At 300kts it would take you about 20 minutes to fly from your "offset" to the waypoint.

As for limiting an offset for an explosive weapon to 100m, does make a lot of sense, considering minimum safe distance for "danger close" drops is at least on paper more than 100m for any A/G weapon I can think of.
