IRIS F-16D HUD/CCIP trouble

W

Warrant

Videre Vincere Est
I notice that every time when i start a flight with the F-16D it takes a while before the pitch attitude bars and the horizon line appear. The CCIP seems to be connected to that; meaning No Bars & line; no CCIP.

Normally it takes about a minute of five to six for the lines and bars to appear. When airborne prior to that....no bars and lines at all and therefore no CCIP. This is quite a hamper when simulating a GCAS (or QRA for CAS) mission.

Is there a perfect/quick instrument/knob setting manual that guarantees these bars, lines and CCIP to show up?

Best regards, Warrant

P.s. I posted the same Question @ IRIS forum. Perhaps someone over here, who does not visit the IRIS forum often, has a smart solution
 
IIRC, the quickstart switch behind the pilots joystick should do it.. I know the horizon lines and many other features are disabled until the INS is aligned. However, there are so many unique systems coded in that there may be multiple reasons for the HUD not having full functionality for a time.

Generally, the quickstart switch will power up all systems to their pre-takeoff positions, including instant INS alignment.

Thanks David :wavey:. That one is to obvious :icon_lol:....when simulating a QRA scramble (still wanted to do it by the book, and wanted all the systems to respond in the same pace) :ernae:
 
I do know that prior to our planes being upgraded with GPS (2002), INS was the primary navigational system and whenever we would assist the crew chiefs with launches I always wondered why the aircraft would sit in the chocks for so long before they taxied. Finally I asked the pilot when he parked at the end of the sortie and he said it was because they had to allow the INS to align first before they could taxi. They waive that for scrambles, but they are still giving the INS time to align even while scrambling.

What did you do? You were sheet metal, right? (don't be offended if I got the wrong job please)
 
In my A-7E squadron, many moons ago, when our planes were part of the alert package on the ship, we would connect power to the planes, and get the INS aligned and ready to go so all the pilot wouldn't have to wait for that. It took about 8 minutes to fully align, IIRC on the old A-7s. Even at home, during a routine flight, we would often do this, because we had to fix it (quickly) if it broke during the launch, so we wanted to make sure all that stuff was working before the pilot got to the plane.
 
Just some background info: ;)

In the real F-16 you can do an alignment, then "store" the results. And if you don't move the aircraft until the next time you power up the jet, you can do a much shorter alignment. I think that is what is done when the jets are on alert. Starup once, do all the checks, align the INS, shut-down. When duty calls ;) just hop in and use the fast align feature, and your all set in under 4 minutes.

In the FSX F-16D the INS does not feature such a "stored HDG" alignment.
The normal alignment takes just over 7 minutes. If the aircraft is moved during the alignment, it takes longer.

Cheers, Michael

Thanks for the extra info, Michael.

Last night, with the quick start feature it took me about 7 minutes before i was good to go.

Also; If you t/o before alignment and engage an autopilot feature the alignment will never happen, i discovered.
Lesson learned, wait for alignment before t/o :engel016:

All very nice and realistic features in this bird i can very much appreciate.

Job very well done 666/IRIS :medals:
 
INS isn't the only thing that requires alignment before aircraft movement. Planes equipped with EFIS have to be aligned, and HUD's are basicly a form of EFIS. EFIS is driven by the Attitude Heading Reference System (AHRS), which is composed of gyroscopes, computers, magnetic flux detectors, compensator units, ect. So, along with INS, the AHRS needs to be aligned, and depending on the plane and circumstances it can take anywhere from 70 seconds to 10 minutes. Disclaimer: The military version of AHRS may be called something else, but to civilian guys like me it's known as AHRS.

These systems are called something different on virtually every combat aircraft because they were all usually purpose built and not off the shelf (at least on combat aircraft). The essence is the same, there are a few computers that mesh multiple nav systems together, have their own gyroscopes and counter checks but need to be aligned. The part that cracks me up is how a 45 minute alignment takes 15 minutes. :icon_lol:
 
Hi All !
Sorry my Bad English .
Ive a problem with my I.R.I.S. F16D .The problems began at startup ,when i set the mainswitch on Battery have failed FLCSPMG light ,dose notilluminate .The second is at FLCS PWR test there are 3 posse at start is on Normal .When i'm switch to test all leds (A,B,C,D) are illuminate n stay like at switch .But I'm switch to Main than happens like normal test procedure .The Third is after switching from Battery to Main n than JetFuel Starter 1 is the next step but i can set only on Starter2 isn't possible to switch on Starter1 .OK .I switch on Starter2 sounds like good the RPM is Climbing to 20 %.
than i pull the throttle a bit forward .Dose not happening .Dose not climb the RPM to 60 % ,engine isn't started.I need to hit onCtrl+Shift+F4 than is on right way engine is start .Why cant i satart the engines without keyboard ?Anybody can help me what i need to change in .cfg to have all function in rightway ?

Have you tried the quick start switch next to the control stick? That always works for me.
 
Yes i tried that but i need hit at first Ctrl+Shift+F4 .Than it's work .
But it is so Dummy .
But realy Thanks a lots
 
Control+shift+F4 should be mixture to full rich. This should have no bearing on a jet, unless I'm mistaken.
 
ctrl-shift-f4 is mixture full rich - or engage fuel flow for a jet. You regularly need to use shift-ctrl-f4 when starting jets, particularly if you used ctrl-shift-f1 to shut them down!
