fighter1976 Posted April 19, 2016 Share Posted April 19, 2016 Hi! Have a problem when start up the plane. Everyhing is ok, except the EAC. It stays on (the warning light) and all the CBU 107 in the DSMS show a text saying "ALN UNS"-when flying it can't be deployed. What am I missing? Thanks Link to comment Share on other sites More sharing options...
Sryan Posted April 19, 2016 Share Posted April 19, 2016 You need to wait for allignment to complete ( it should say T = 4.0.0.8 on the CDU) before you press NAV. You then need to flick up the EAC switch below the throttle ( you can't do that if allignment didn't complete). Check my F-15C guide Link to comment Share on other sites More sharing options...
BaconSarnie Posted April 19, 2016 Share Posted April 19, 2016 You need to wait for allignment to complete ( it should say T = 4.0.0.8 on the CDU) before you press NAV. You then need to flick up the EAC switch below the throttle ( you can't do that if allignment didn't complete). You missed press the EGI swicth on the panel at the bottom, just behind the stick. Press that after pressing the NAV OSB next to your MFCD. And lo, Reverend Vegas did say "Take forth unto the infidel the mighty GAU 8 and expend its holy 30MM so that freedom will be brung upon them who knoweth not the joys of BBBBBBBRRRRRRRRRRRRRRRRRRRRTTTTTTTTTT" "Amen" Link to comment Share on other sites More sharing options...

fighter1976 Posted April 19, 2016 Author Share Posted April 19, 2016 followed the indications but "ALN UNS" still shows-although the EAC is working now...another thing -before even the GBU 38 was reading "ALN UNS", now at least the GBU 38 is working, but CBU 105 is still not...

Zabuzard Posted April 19, 2016 Share Posted April 19, 2016 Mhh, please crosscheck your startup checklist with a checklist that you know works. If I don't forget anything the steps are: - Wait for automatic ground alignment to finish (4.0 0. 8, do not move the aircraft while aligning) - Click Nav on the CDU to start the navigation system and exit alignment - Select EGI as navigation data source (GPS system, button located under the ADI) Also make sure: - IFFCC, JTRS and CICU on (bottom of weapon control panel) - EAC on (confirm that warning light goes off) - SAS on Afaik then it should not read "ALN UNS" anymore, even on ground before takeoff it would already read "RDY". If it still shows ALN UNS you're probably doing anything in the wrong order at your startup procedure. Link to comment Share on other sites More sharing options...

Zabuzard Posted April 20, 2016 Share Posted April 20, 2016 Image with all stuff I mentioned: EAC - Enables autopilot and gun stability system (PAC) SAS - Enables control input dampening system, flying smoother, needed for EAC and other stuff to work EGI - Enables EGI as navigation data source, this is a GPS system IFFCC - flight and fire control computer, also enables HUD JTRS - Enables datalink system, you can see other aircrafts on the TAD CICU - Central Interface Control Unit, enables MFCDs and subsystems Link to comment Share on other sites More sharing options...

fighter1976 Posted April 20, 2016 Author Share Posted April 20, 2016 it works now..you have to wait a little even after the alignment is done until CBU 105 says "RDY" Link to comment Share on other sites More sharing options...
rnb197 Posted April 25, 2016 Share Posted April 25, 2016 I had the same problem with the EAC.... flicked it on at the correct place in the check list but it didnt stay on. Once i programmed one of my throttle switches to that command it worked perfectly... try that. Best of luck. Link to comment Share on other sites More sharing options...
