Jak525 Posted May 7, 2019 Share Posted May 7, 2019 (edited) When in A/G master mode and employing bombs, an "A" or "R" sometimes pops up underneath the altitude box. I can't figure out what triggers either of them - not mentioned in the manual or any videos I've seen. Edited May 10, 2019 by Jak525 Link to comment Share on other sites More sharing options...
Cytarabine Posted May 7, 2019 Share Posted May 7, 2019 R = radar altitude B = barometric altitude Generally when your radar altimeter is on as the HUD altitude source. Link to comment Share on other sites More sharing options...
Jak525 Posted May 7, 2019 Author Share Posted May 7, 2019 R = radar altitude B = barometric altitude Generally when your radar altimeter is on as the HUD altitude source. Negative, it's not correlated to the barometric / radar altitude indication. That still shows up (when source is set to radar), to the right, independently of the A or R indication Link to comment Share on other sites More sharing options...

Gierasimov Posted May 7, 2019 Share Posted May 7, 2019 R, B and A are shown only when a bomb is selected. I believe, based on my observations and also some of the documentation of similar HUD displays, that it relates to the sensor that takes part in CCIP calculations. When you are below 5000 feet it shows R initially. Above 5000 feet it shows B which corresponds to the radar altimeter scale as well. A is shown while in dive. I think it still shows R - Radar altimeter used for the bombing in CCIP (irrelevant of RALT switch position); B- barometric altimeter; A - (?) available (?)

Knives Posted May 8, 2019 Share Posted May 8, 2019 A - Most probably is calculating the slant range and hight using the A/G radar. Because for accurate CCIP you need the range too. Further when you are in steep dive the RALT is not accurate due to the location of the radar at the tail. Link to comment Share on other sites More sharing options...
Jak525 Posted May 8, 2019 Author Share Posted May 8, 2019 I also saw a "B" below too. When I turned off the radar altimeter the "R" would consistently go away immediately (and come back when I turned it back on), so it's definitely got to do with using that. I'd imagine B means barometric, yeah. I have no idea what A means though. It's not the radar -- I turned that off to test. Maybe ED can let us know, as I've never heard this mentioned.

dorianR666 Posted May 8, 2019 Share Posted May 8, 2019 I have no idea what A means though. It's not the radar -- I turned that off to test. AG radar is not yet implemented. It can be an always-functioning stub, so to speak. CPU: AMD Ryzen 5 1600X GPU: AMD RX 580 Link to comment Share on other sites More sharing options...
whaaw Posted May 8, 2019 Share Posted May 8, 2019 now im confused, i thougt its like this: R shows when ralt is selected and you are below 5000ft and in normal attitude (not upside down). when you go above 5000ft you get a blicking B meaning it shows barometric now, or you should switch to balt. when you switch to balt, the B vanishes and you now have only the numbers.

Gierasimov Posted May 8, 2019 Share Posted May 8, 2019 Correct now im confused, i thougt its like this: R shows when ralt is selected and you are below 5000ft and in normal attitude (not upside down). when you go above 5000ft you get a blicking B meaning it shows barometric now, or you should switch to balt. when you switch to balt, the B vanishes and you now have only the numbers. Yes you are right. This is how it works. We are talking about another indication, just below altitude box on the HUD. A, R, or B is visible in addition to the above when you select a bomb.

Maybe ED can let us know, as I've never heard this mentioned.Look here how the "A", "B" and "R" changes depending on height, angle and range. For a high level of certainly, the "A" is calculating range and height by A/G radar. Where "B" is calculating range and height by Barometric Altimeter and INS. And "R" is calculating range and height by Radar Altimeter and INS. So, how that can help? When you see "A" that's mean is most accurate, then "R", the "B" is the least accurate.

QuiGon Posted May 10, 2019 Share Posted May 10, 2019 How does it decide when to use what? Can it be manually comanded to use a specific source (A,B,R)? Intel i7-12700K @ 8x5GHz+4x3.8GHz + 32 GB DDR5 RAM + Nvidia Geforce RTX 2080 (8 GB VRAM) + M.2 SSD + Windows 10 64Bit DCS Panavia Tornado (IDS) really needs to be a thing!
