Found out why the VNAV wasn't working, i hadn't added a cost index (still no idea what that is) It still won't add any stars info though? Anyone want to help?

Cost Index works like this. If you enter 9999 the plane will fly flat out and burn fuel like crazy and it has a very short range! However. If you make the Cost Index 0, you will get a nice slow and economical flight with a long range for the aircraft.

I generally use a Cost Index of between 0 and 100. 0 if I'm doing a long distance flight (close to maximum range) and usually 40-50 for shorter range flights. I use 100 if it's a very short flight of less than 1 hour.

Hope this helps.
