"Also remember that TL mode is limited to ~7km, so you'll have to be pretty close to get a lock. " It should be limited to 6 NM

The way it works in the Sim imo The Button (V) activates Combat Flaps The Lever (Lctl V) deactivates the combat flaps. The Real Aircraft Manual basically states: The Button allows the lever to be selected to activate combat Flap (i.e. the button effectively unlocks the lever) Then activate combat flaps with the lever. To Deselect Combat flaps the lever is selected off. So imo what we see in the Sim is at variance with the real world. (Though functional in the sim).

Same seems 3.8nm lock in TEL versus IL76. Couldnt lock in BPZ

Really no radar assisted gunsight or simply not implemented yet?
IvanK replied to Snappy's topic in DCS: Mirage F1
The fore/Aft switch is associated with the R530 missile in a jamming environment. It is used to tell the missile the engagement aspect i.e, Fore = Forward sector, AFT = stern sector. This then determines the warhead Detonation delay after the prox fuse detects the target. Since firing against a Jammer neither range or range rate are known by the system. It also varies the navigation computation. In a normal (non jammer) R530 launch this detonation delay is set dynamically immediately prior to launch as the system knows both range and range rate. -

With a Radar lock its a standard LCOS Gyro gunsght with radar range input. Range shown by the drum at the top of the glass. With Auto/Man switch in Man radar range and gunsight derived turning rates are used to compute the solution and position the pipper. A 2 second tracking time is desired to ensure a valid solution. With out a radar lock the sight is a standard LCOS Gyro sight with 600m or 300m range input depending on the pilot pushing the 600m/300m switch. Again 2 sec tracking time desired for a valid solution. With Auto/Man switch in AUTO then Radar range, radar determined Line of sight rates and own aircraft determined turn rates are used to determine the solution, in addition if the trigger is held depressed the gun will fire automatically when specific criteria are met.... Pipper and TD square within 15mills . No specific tracking time required -

IvanK replied to Snappy's topic in DCS: Mirage F1
Auto/Manual firing switch has two uses. in the R530 with the switch in Auto the R530 will automatically fire at a range known as "Topt" basically heart of the envelope (though specific criteria defines Topt ... basically calculated Missile flight time as a function of closure. In AA guns with a radar lock and Auto selected and the trigger depressed the guns will fire automatically if specific criteria are met. -

How I believe the real aircraft works... according to the docs available. -
Sight reticle and ground attack with rockets or guns
IvanK replied to Leviathan667's topic in DCS: Mirage F1
Agree it shouldn't imo be doing that ... perhaps this AG side of things hasn't been implemented yet. -

IvanK replied to Leviathan667's topic in DCS: Mirage F1
Cant find a reference but I believe in AG the reticle should be fixed and only moves in the vertical by way of the set depression. -

IvanK replied to Snappy's topic in DCS: Mirage F1
I believe the C+M switch (Also known as rapid gun in some pubs) should do the following: 1. Force the radar into TEL mode 2. Selects the IR missiles ... With the R550 in 30 x 30 scan (did in Mir III) 3. Firezone computer post lock performs missile in zone computations and generates Green light if in zone. 4. Gun Gyro reticle becomes computing with radar range and own body rates (or Radar rates if Auto fire switch in AUTO) This enables immediate employment of either IR missiles or the gun. -
Fuel consumption rate possibly being modelled too high
IvanK replied to Giskvoosk's topic in Bugs and Problems
FWIW ATAR 9C Mir IIIO Full AB on the deck 60imp Gal per min so about 28,160pph. Thats a 13,000lbs thrust ATAR. -
Wake turbulence causes engine stall, shut off or plane destruction.
IvanK replied to diditopgun's topic in Bugs and Problems
Flown through a lot of Aircraft Efflux/wakes inside 200m range with ATAR 9C ... not one compressor stall or hiccough, cant see why the ATAR 9K 50 would suddenly be susceptible to this- 15 replies

Br easier IMO if there were just two Bindings. "Flap Up" and "Flap down". With each push moving the flaps 1 step in that direction. so from Flaps Fully down to up would require 2 pushes of the "Flaps up" keybinding etc.

For those that like this sort of thing Dotted circle represents the Rapid Gun Radar FOV .. most of the Combining glass.

Nope only "expertise' I had was with R530 Radar variant.

Talking about the Radar. Pretty sure the R530 itself was NOT monopulse
-
The Monopluse side of things as far as I recall was only used for the tracking of the target. Essentially by use of a 2 things called the "Magic T" and the "folded T". The Magic T divided the received pulse into 2 quadrants and could then determine precisely within the beam the targets exact elevation position. The Folded T did the same simultaneously in elevation ... all happening within a single return pulse. This just allowed very fine angular position information to be determined in a single pulse which was then used to ensure the range gate stayed with the target. It was very much better against range gate stealers than say Conscan trackers used in typical US radars of the same vintage. The R530 just needed the RF to home on and (again as far as I recall) wasn't really a monopulse per see being a passive seeker. It was a cumbersome thing to use with an unbelievably low Pk. There was an agonizing 1-4 secs delay after lock on during which time the radar and and the missile synced frequencies (there were 10 available and randomized) and ensured the seeker wasn't masked by the aircraft itself (could be an issue as in the Mirage III it was only carried on the centreline). After this 1-4 secs delay the missile was considered viable. This delay was a serious operational limitation against High speed targets in front quarter intercepts. To get the best out of the Cyrano II (and I don't see why the IV is any different) required almost continual attention to manual Gain control coupled with Screen intensity and target aging and Antenna elevation and of course each aeroplanes radar performance and set up was different.
-
Cyrano II in Mirage IIIO/E was in Track (STT) a Monopulse radar.

Lovely vid ..... Tad less gain to reduce the speckle
-
The "speckle' and lock on/Stop program in the radar looks great.

reported earlier Is the DUD cue for high-drag bombs wrong?
IvanK replied to raus's topic in Bugs and Problems
The DCS calculation and mechanization of the pull up cue is in error and way to pessimistic. This has been reported. I suggest this is the main issue that you are seeing. -
Just a comment. The end of transfer lights on the fuel panel are very very dim in daylight even with the rotary dialed up to maximum brightness.

Ok thanks for the input now sorted.
-
The docs say that the AP ON/OFF switch can be used to override the elastic stop. Does this actually work ... it doesn't for me.

Yes Basic AG mapping exists in the cyrano IV Reasonable CYRANO IV Radar manual in English here: https://dlscrib.com/cyrano-iv-airborne-fire-control-radar-utilization-manual-thomson-csf_58b1f5516454a7ab10b1e966_pdf.html
