we just key in the airport code on the Pos init page. We do use the GPS pos 1 and 2 for our position. The people in bombardiers suspect that it could be an issue with the IAPS box. So we are gonna switch the box and resolve. Hopefully that will fix the problem. We can’t engage out Autothrust during take off. Only able to engage it when airborne due to the conflicting information the FMS is receiving. FMS 1 is on the ground and FMS 2 is in the air. Thanks for your help
