Why is GPS aligning sometimes and sometimes not at start?

I fly the F18 for some time now. One thing that goes wrong more often than not, is the GPS alignment. Both in mulitplayer as in campaigns.

I follow the start up procedure that is basically: battery on, APU on, Starting engines, then GND or CVN alignment, HSI- STD HDG-. Than finger crossed it goes well an it ends with verdict "Qual OK" and i switch to IFA mode. 

But it frequently happens that it is aligning and before it ends in a OK it says No ATT. Then i just put in IFA (i noticed that since 2.8 it then is able to start aligning in air, which saves the day then for me).

I was wondering if this is a known issue, or is a fix i can do when i get message NO ATT? It can be a pain in the ass to fly without AP functions during a CAS mission especially, although it is good for flying skills i'll admit that 😉.

I concur, it sounds like you release the parking break while the INS is still aligning. This will abort the aligning procedure.

I’ve had this happen a few times and can’t figure the cause. Apparently you can just press the stores heading button and forget the full align. I understand there’s no advantage to the full align in DCS

That's correct. Same is true for RL as well.
Unlike in DCS full alignment is usually not available IRL, as the jet (or rather its INS) needs to prepared for that beforehand. It's usually used for QRA duty.
