Thanks i am seeing patrols tagged as "float", i guess if i do not put that tag in a PV1 Ventura it is only land based so not a problem. One of the advantages of Patrol classification is that the can do naval search at night, a Level Bomber do not so for long range land based patrol aircraft with radar even makes more sense to classify them as patrol.
It does not work like that. It seems I wasn't clear enough before.
1. The "amphibian" check box, if checked, allows that aircraft model to operate from any size 0 and above airfield which is located on a coastal hex or a non-coastal hex.
2. The "float capable" check box, if checked, allows that aircraft model to operate from any size 0 and above airfield which is located on a coastal hex. That aircraft model cannot operate from a non-coastal hex.
3. Any aircraft model which is classified as a PA (patrol), FP (float plane) or FF (float fighter) is automatically treated by the code as being "float capable" and does not need that check box checked in the editor in order to operate from a coastal size 0 airfield.
If you reclassify the PV1 Ventura to be a PA type, it will be able to fly from a coastal size 0 airfield. It will not be possible to restrict it to fly only from a non-coastal airfield. If, in addition to reclassifying it to be a patrol type, you also check the amphibian check box, it will also be able to fly from a non-coastal airfield.
With the current game code, it is not that obvious that it makes more sense to reclassify level bombers to the patrol classification. This is another of the many occasions where you just have to accept the game engine's limitations do not allow your ideas to be implemented without opening a can of worms.
