Title: alignment time
Post by fturnerj on May 7^th, 2011, 11:43pm

I waited for a hour and it never got below 6. It went from 9 to 6 very quick. The green align light never came up. I didn't move the plane. I sat there with the brake on waiting. Whats wrong?

Did you follow the POS input procedure "exactly"???
The following is an extract from the VC10 flying manuel.
Follow it CAREFULLY!!!!
And, remember to input lat/Long in the correct format
e.g. EGLL N51º 28'2 W000º 27'5 is input as:-
N51282<insert>W0275<insert>
