some1 Posted March 7, 2018 Posted March 7, 2018 (edited) Viggen uses a special INS system, it uses a technology called ternav to help reduce the INS drift and it require rather frequent updates to stay precise.

jojo Posted March 7, 2018 Posted March 7, 2018 (edited) the one where I place a green " + " icon on the ground on my HUD and then fly towards it and drop the bomb when the greenbar comes from bottom of HUD and moves up... :P In French "CCPL direct" or "direct CCRP", the other one being "CCPL + PI" where you designate an initial point. In "CCPL direct", when you perform target ranging, the system record target position relatively to your aircraft, so navigation drift isn't a factor anymore after target's designation. That's why you don't really have "blind" bombing mode based only on target's coordinates. You need to get line of sight on on target or Initial Point so during the attack you can bypass navigation system drift. That's Mirage 2000C RDI. On the other hand, and Mirage 2000D, with a far more accurate navigation system, would be able to put dumb bombs on target, hands off in terrain following and 0 visibility.

Frederf Posted March 8, 2018 Posted March 8, 2018 It's a good question though. How badly/off/secours does the INS need to be before AG computed bombing degrades or is unavailable entirely?
jojo Posted March 8, 2018 Posted March 8, 2018 (edited) It's a good question though. How badly/off/secours does the INS need to be before AG computed bombing degrades or is unavailable entirely? It doesn't really matters, you don't need target coordinates to attack. The problem isn't navigation accuracy once you have eyes on target. As long as INS gives you attitude it's Ok. If INS attitude fails, probably you will have to go "secours". Think of it like MiG 29 for attack run. Edited March 8, 2018 by jojo Mirage fanatic !

myHelljumper Posted March 11, 2018 Posted March 11, 2018 P comes up only if the engine is at certain RPM I just checked this and when you have Ground power and put the radar operation nob to P CH you have a P displayed on you VTB even with your engine off.

jojo Posted March 12, 2018 Posted March 12, 2018 (edited) So realistic or not currently, Helljumper? For sure, you won't be able to warm up the radar on internal battery ! If I understand well the electrical diagram on Mirage 2000C RDM manual: - radar is on ALT 2 shed bus. - ALT 2 shed bus is fed by GPU. So what myHelljumper described seems to be correct. :thumbup: Edited March 12, 2018 by jojo Mirage fanatic !

Frederf Posted March 13, 2018 Posted March 13, 2018 Radar is almost certainly high power alternating current coming from AC generator or AC external power. Airplane probably makes a tiny bit of AC from converters but that would be reserved for critical and low power systems. Radar preparation cannot happen until AC power on the AC bus which powers the radar is available. This power may come from an external source or from the engine-driven AC generator. The AC generator is usually automatically unattached from the AC bus until the engine is above a certain RPM to prevent undue load on the engine at low speed and to ensure sufficient electrical output.
D4n Posted March 16, 2018 Author Posted March 16, 2018 Ok I tried with ground power on instantly (before doing auto-startup), but the "P" on the radar display still takes long time until it starts flashing (warming up?). I have it in SIL to warm up, or will it start warm up earlier when I put it to P CH mode first?
