AHRS alignment times
Posted: Wed Oct 02, 2013 10:46 pm
I think this is more an AHRS question than a WS EFIS question but this appears to be the best spot in the Forum to ask since I am a WS owner.
I am curious what influences the alignment times shown on the PFD during boot of the system.
Mine seems to be a random selection that is sometimes 45 seconds and sometimes 2 minutes.
I know of the commentary that it only takes 15 seconds or so and you can move after that, but during Phase 1 last year I had the AHRS tumble on two different occasions because I did not wait long enough. Because of that, I began waiting until it is really finished. I can't afford a tumble in the soup.
SO...My machine was pretty constant at 45 sec unless I accidentally let the brakes slip and then the 2 minute jobber would come up.
I upgraded the AHRS and WS software a few months ago. From v34 to whatever is latest today, and the instances of 2 minute boots really increased.
Therein lies the curiosity. I want to do what is needed to get the boot times back down as a normal course.
