Sylvan Posted January 5, 2014 Posted January 5, 2014 (edited) Hi guys! I have a question about the "heading/range to target point" readout on the PVI-800 panel. By this I mean the button on the bottom right of the PVI-800. I searched for it but couldn't find it had been asked before. In the manual (p. 6-65) it says that the readout should contain the heading in degrees in the left part of the upper row and the distance to target in kilomters on the bottom row. These work as described. However in the game there appears an extra set of three digits in the top row on the right which aren't described in the manual. Example: I spawned in the "Take off from Beslan" quickstart mission, designated a target point to the right of the runway, heading 124° and 3,6 km away. I select NAV/TGT 1 on the PVI and hit the HEAD/RA TGT PNT button. The display top row now reads 124'30'0 and the bottom row reads 003'6. At first I thought it might be the reciprocal heading, so to get some more data I designated another target point bearing 110° and 4,5 km away. The readout is now 110'22'2 and 004'5, which shows that this is clearly something else than the reciprocal. In the DTA/DH mode these top three digits are estimated flight time to the target in minutes, but that doesn't fit these values either. When out flying, these three numbers change wildly, although sometimes if you're flying directly at a target point it seems to be counting, sometimes up, sometimes down. So does anyone know what those three right most digits are supposed to mean? Edited January 5, 2014 by Sylvan Clarification
AlphaOneSix Posted January 5, 2014 Posted January 5, 2014 (edited) DDMM.MM Degrees, Minutes, Tenths of Minutes. 124°30.0' 110°22.2' Edit #1: I actually don't know for sure. I will check. Edit #2: Okay, I checked. That is indeed what the number is representing (Degrees, Minutes, Tenths of Minutes). The manual indicates that only the degrees should be displayed, not minutes, and that the last three blocks should be blank, however it does appear that the PVI display is showing more data than is specified in the manual.

ED Team Raptor9 Posted January 5, 2014 ED Team Posted January 5, 2014 (edited) On Page 6-64, Item 20 (bottom of the page) it addresses what that button is supposed to do as I'm sure you've already read. However, the manual says "Indication of heading and range to target in the Ingress mode." It sounds like its referring to the "DLINK automatic ingress to target" button, the center yellow button on the datalink panel. Not sure if you've ever used it, but if you push it after selecting a datalink symbol, and then uncage the Shkval, the Shkval automatically slews to the target. Anyway, I would try selecting the PVI TGT point as before, but then selecting "ingress to target" on the datalink panel, and then push the "heading/range to target" button on the PVI. See what that does; just a shot in dark, but give it a try. EDIT: Tried it myself, but the datalink panel's "Ingress to Tgt" button has no affect on the PVI readout. On the other thing you said, when in DTA/DH mode the top right numbers appear to be counting up or down, that might be a result of a change in speed. It's calculating the time en-route using the range remaining and you're average speed. If you slow down or speed up, that will slowly change the average speed you've been flying, and the numbers will be recalculated as long as the mean value is shifting. Just another thought. Where's a Kamov avionics engineer when you need one...:doh: Edited January 6, 2014 by Raptor9 Afterburners are for wussies...hang around the battlefield and dodge tracers like a man. DCS Rotor-Head
Sylvan Posted January 6, 2014 Author Posted January 6, 2014 Degrees, Minutes, Tenths of Minutes. 124°30.0' 110°22.2' Minutes and tenths of minutes -- on a bearing indication? :unsure: Not that I don't believe you, but when would a pilot ever need that much precision?
AlphaOneSix Posted January 6, 2014 Posted January 6, 2014 when would a pilot ever need that much precision? I think most would agree that such a level of precision is unnecessary. The manual indicates that only the bearing in degrees is shown. In-game, however, it is shown all the way down to 1/10th of a minute. Either the manual is wrong, or the game is wrong. In this instance, my opinion is that the game is wrong and is indicating too much precision.
