john4pap Posted April 13, 2022 Share Posted April 13, 2022 Is it normal that when the antenna elevation is centered the search area shown on the screen is 100k feet and more? I have to get it all the way down to get anything rational, that is something like 1 to 29 thousand feet. At the moment, I'm flying at 7000, the cursor is set to 21 miles and the search area while the antenna is centered is 98 to 117 thousand feet.

myHelljumper Posted April 13, 2022 Share Posted April 13, 2022 Hi, You must have not set your altitude correctly when doing your INS alignment. The default BUT altitude is 99999 feet and the radar uses the altitude from the INS to compute the antenna search altitudes. 1 1 Helljumper - M2000C Guru Helljumper's Youtube https://www.youtube.com/channel/UCK3rTjezLUxPbWHvJJ3W2fA Link to comment Share on other sites More sharing options...
john4pap Posted April 13, 2022 Author Share Posted April 13, 2022 This was it. I got into the bad habit of never checking altitude for INS alignment back when the initial altitude was always already set correctly. This should also explain why I couldn't see the cross on the HUD for some waypoints when approaching them. Many thanks! Link to comment Share on other sites More sharing options...

I also got bitten by this issue and it took me half of forever to understand the cause. (yes call me lazy, I used to skip setting the ALT value before alignment). Did the default altitude change from zero to 99999 at some point ? Or maybe in the past the radar used to read the altitude from the altimeter ? Anyways, that seems a bit strange to use the INS to feed the altitude to the radar, is that the same on other airplanes ? I always thought they used data from the altimeter...

myHelljumper Posted April 14, 2022 Share Posted April 14, 2022 Hi, Yes, the radar altitude source info changed some time ago with the radar rework. The radar needs the INS to do a lot of its function and the INS altitude is supposed to be quite precise. 3 Helljumper - M2000C Guru Helljumper's Youtube https://www.youtube.com/channel/UCK3rTjezLUxPbWHvJJ3W2fA Link to comment Share on other sites More sharing options...
Smokin Hole Posted August 17, 2022 Share Posted August 17, 2022 This has confounded me for a year! It never happened to me in singleplayer. So I assumed it had something to do with multiplayer. Facepalm! 1 Link to comment Share on other sites More sharing options...
