Thanks for your reply.
I admit I ticked the NATS option in the route planner so that is my oversight.
The reason I did this was that without the NATS option the route EGCC to KMCO was for some reason taking me south to the Canaries and beyond before lurching back north towards the destination. The FSX flight planner also does the same and I don't understand why, unless NATS are a requirement for this route to pan out as expected, i.e. across Irleand, across the North Atlantic and down the east coast of the USA.
Regarding EGCC. I commented out the entry for EGCC in Runways.txt as I use the UK 2000 Manchester Extreme scenery which has the correct runway designations of 5L, 5R, 23L, 23R. This allowed me to select SIDS and STARS for EGCC in EFB.
The ILS frquencies show in FSX but not in EFB. Could they be missing from the navdata? How do I check?
Thanks, Daz
