Cibit Posted March 13, 2011 Posted March 13, 2011 Ask for ground power and you can start aligning immediately, before even switching on the lights. I don't do anything with electronics until I'm fully aligned. *Wait for alignment to finish *Switch from ground to NAV *DTS upload *BITS test I've found that there are fewer CCIP and DTSAS errors this way. WTF? thats like backward surely. Do you not need to load all before alignment? I always thought you had to. And if ground power is on then you have enough juice for all the preflight shniz??

nomdeplume Posted March 13, 2011 Posted March 13, 2011 When the plane switches power source (ground power -> engines or APU -> engines) everything gets reset. I don't think this loses alignment, so you can still align prior to switching over, but some other systems will be rebooted. I'm not sure how severe switching from ground to engine generator power is. It might not be too bad. In a recent flight I went to hit 7 on the UFC and my view wasn't in the right place and I clicked a bit quickly, and got the left engine fire T-handle instead... the systems did reboot, but I didn't seem to have lost anything. I've tried a few variations of the startup and can't get the HUD to show DTS mode by default no matter how long I wait to switch the IFFCC on. It always switches to showing the steerpoint elevation.
StrongHarm Posted March 13, 2011 Posted March 13, 2011 Nope.. you have to align your systems then you push the data to them. It's like penciling in a drawing before you apply color to it. And nope, going from ground power to generators doesn't cause reboot of anything. Ground power is plugged straight into a shunt in the primary bus. Once your engines are up and your gen switches are on, you can unplug ground power and your systems will all be the same. (NOTE: According to paulrkiii, who is a crew chief on Hawgs, you're not supposed to have ground power on during engine start in real life, but we also don't have huffers in the sim, so I do it anyway) I'll post a track of my startup sequence when I can. It's a good thing that this is Early Access and we've all volunteered to help test and enhance this work in progress... despite the frustrations inherent in the task with even the simplest of software... otherwise people might not understand that this incredibly complex unfinished module is unfinished. /light-hearted sarcasm
winz Posted March 13, 2011 Posted March 13, 2011 Then why are you powering other systems in the training mission while EGI is aligning. Is the mission wrong? I see logicaly nothing wrong in loading TAD/DSMS Inventory + profiles/TGP Data/MFCD page configuration while nav system (EGI) is figuring out and fine-tunning it's place and orientation in space.

Eddie Posted March 13, 2011 Posted March 13, 2011 No reason at all not to load the DTS while the EGI is aligning, EGI alignment has no impact on loading data. DTS data can be loaded as soon as the CDU has completed it's BIT and the DTC has loaded. And as for ground power, IRL ground power is never applied to the aircraft with the APU/Main generators running, and is not used during startup. Of course there is no reason you can't do so in the sim if you want to speed things up a bit.
StrongHarm Posted March 13, 2011 Posted March 13, 2011 Attached is my startup sequence with ground power. Eddie, I wouldn't presume to argue the point with you, but it seems that if I load DTS before EGI is fully aligned, my Target Altitude Reference is set to the altitude of my waypoint rather than DTS. If I align and then do my DTS upload and then my HUD BITS, my Target Altitude Reference is DTS without me having to manually switch to it. How does this work? No reason at all not to load the DTS while the EGI is aligning, EGI alignment has no impact on loading data. DTS data can be loaded as soon as the CDU has completed it's BIT and the DTC has loaded.

S77th-konkussion Posted March 14, 2011 Posted March 14, 2011 Guys, I've tried to wait for the lignment, but the problem is that the lever comes back in the off position any time I try to arm it anybody else have this problem? You're not waiting long enough. Try this startup procedure. Just my variant among others. I tried to list items in a timeline that accounts for items that need time to "boot up" so to speak.. https://docs.google.com/document/d/1OofEfpi9kHG_jmvT8Z3BXrgOD9AZzJrLgKAI-yF0-Q4/edit?hl=en&authkey=CI-D4mY# 1 [sIGPIC]http://forums.eagle.ru/attachment.php?attachmentid=43337&d=1287169113[/sIGPIC]
StrongHarm Posted March 14, 2011 Posted March 14, 2011 Also, your SIS pitch and yaw switches have to be set before you can switch EAC on. Watch my startup track.

Scabbers Posted March 15, 2011 Posted March 15, 2011 Ground power on the A-10C is for maintenance only. Never, repeat, NEVER is ground power used to start the aircraft. The APU is the source for starting the aircraft. Now where is that speed brakes control again? [sIGPIC][/sIGPIC]
bob_baer Posted March 18, 2011 Author Posted March 18, 2011 EAC problem track file Hi guys sorry just come back home after one week. Attached my track file with my start up procedure and the eac lever that doesn't work. Can you help me? thanksEAC error.trk
nomdeplume Posted March 18, 2011 Posted March 18, 2011 (edited) Hi guys sorry just come back home after one week. Attached my track file with my start up procedure and the eac lever that doesn't work. You need to wait for the EGI to completely align, the "INS NAV READY" text at the top will start blinking when it's fully aligned (at T=4.0). You then need to press the NAV button to change it from alignment mode to navigation mode before you enable the EAC switch. You can switch to NAV mode prior to attaining full alignment (i.e. once it says "INS NAV READY" but isn't blinking) but you won't have full accuracy and I don't think EAC will work until it's fully aligned.

aerick911 Posted March 18, 2011 Posted March 18, 2011 Weird question. Do you think moving the rudders back and forth and the slight movement it causes in the aircraft with NWS on causes the alignment to fail? I've done every step correctly, and sometimes EAC still fails to arm because ground alignment gets "stuck". [sIGPIC][/sIGPIC]
bob_baer Posted March 18, 2011 Author Posted March 18, 2011 actually it was fully alligned. Are you sure this is the problem? Isn't it a bug?
=Panther= Posted March 18, 2011 Posted March 18, 2011 actually it was fully alligned. Are you sure this is the problem? Isn't it a bug? I just watched your track and it wasn't fully aligned. The words INS NAV will flash when it is ready. You were only 1.8 of 4.0 into the alignment when you tried activating the EAC.

eodcheese Posted March 18, 2011 Posted March 18, 2011 actually it was fully alligned. Are you sure this is the problem? Isn't it a bug? Watched your track. INS wasn't fully aligned. There are 2 things to look for to ensure full alignment is complete. These things are 1) INS NAV RDY will flash... FLASH... when ready and 2) the INS T = 4.0 0.8 . BOTH of these need to be "true" (IOW, both need to be showing on the MFD). You can have T = 4.0 0.8 for a second or two before the INS NAV RDY will start blinking. Only then should you switch the INS to NAV and arm your EAC. (I actually wait until then to arm the SAS and then EAC). Give it a shot. Hope this helps.
milky82 Posted March 18, 2011 Posted March 18, 2011 I always wait untill Im just about to taxi before hitting the EAC arm and thats after the alignment and I have switched to Nav.
nomdeplume Posted March 19, 2011 Posted March 19, 2011 Do you think moving the rudders back and forth and the slight movement it causes in the aircraft with NWS on causes the alignment to fail? I've done every step correctly, and sometimes EAC still fails to arm because ground alignment gets "stuck". It will automatically switch to NAV mode if you start moving, but I wouldn't think the slight movement from turning the nose wheel would be enough to trigger it. It doesn't take a lot of movement though. Sometimes conditions are such that the engines at idle are producing enough thrust to start you moving, albeit very slowly, and this can be enough for it to switch to NAV mode. Alignment can easily be resumed if this does happen, by setting it back to ground alignment mode once you've stopped the jet.
bob_baer Posted March 19, 2011 Author Posted March 19, 2011 Ok I understand my error maybe. Not only I have to wait for total allignment as you said, but also I have first to set cdu to nav. thank you everybody!
