Hi Mark

Glad to report  :)that this time around, I followed your Start-up flowsheet to the tee ,but also remembered after reading your advice above to switch the DC Voltage switches and the AC Paralleling switches to GEN3/GEN4 and TR3/TR4 respectively in turn as these power the AC Aux Pump switches,and indeed watched as those neons went out and thus I was able to gain Rudder control.

Everything to T/O went smoothly.Thanks.I have also integrated your GPS window fix but not yet used it as I now create a FP with both SIDs and STARs integrated,so she can track without any interference from me. :)
