Good Morning,
I am using Prepar3dv4.5...
I have been trying on different airports which I believe like you has got nothing to do with the enigma!
I am using Active Sky, ORBX Base Pack, Add Ons that I have been using all along.
The date is the default System time...
Tried again this morning and as it was early, the default was Dawn and the post pushback checklist "Taxi " did not come on and by changing the time to "Day", it came on straight away.
Seems to me that there is a glitch depending on Time of day...
Thank you anyway for your input.
Best Regards,
