I have done a search on the forum but cannot find a definative answerI have arranged my AI aircraft in a number of Exel worksheets sorted into categories. eg Operators, Aircraft make & model, Military, Cargo, etc. each aircraft with its own unique AC# ID.I want to be able to cut and paste these AI Aircraft into flight plans, keeping their ID, so my question isWhen I compile a flightplan1.Can the initial start number be any number ie. could the first line be AC#365......2.Do the AC# numbers have to follow on and increase by 1 each time eg.AC#365......AC#366......AC#367......AC#368......or can they be displayed in the Aircraft.txt file as followsAC#365......AC#377......AC#412......AC#418......3.If the answer to the above is yes, Do the AC# numbers have to be arranged in numerical order,or can they be displayed in the Aircraft.txt file as follows?AC#45......AC#1006......AC#745......AC#1243......
