Having Trouble with INS Alignment

[redboot]

Since the recent patch, when I start from a cold start, the INS is aligning properly maybe 50% of the time. The other 50%, I start the engine(s), turn on the DDIs, switch to GND, press STD HDG on the HSI and nothing happens. No count-down timer, no qual count-down. Just a 0 timer and "NO ATT" blinking on the qual indicator. If I turn off the INS and turn it back to GND, the STD HDG option on the DDI disappears and still nothing happens. If I quit and restart the mission, it usually is fine.

 

It feels like a bug, but given that I'm pretty new at this, I'm willing to consider user error.

 

Anyone else having this problem? Any feel for what I may be doing wrong

It takes a bit until it starts. Don't know if that's realistic though.

Ensure you keep the parking brake engaged until the INS is fully aligned.

The parking brake may be it. It's worked so far. Thanks.
