AI ships flightplans and afcads

Hi,I ran into a problem which (I think) even Holger Sandmann has not yet solved.Trying to make an AI plan for a speedboat (see jetfoil configuration topic), I faced the taxi speed limit of some 20 kts while taxiing to the 'runway'.The only solution would be in my opinion to let the vessel take off, but without climbing. (Holger's solution is to not have the ship take off at all).Unfortunately, setting the flight level to zero in TTools, prevents the ship from taking off but makes it continue to roll in a straight line without bothering to stop at the next 'airport'.Somebody wrestling with the same problem?Robystar
