AAARRRRGGGGGHHHH, tartenmuche what have you done to me, I had to add something to BAT I might have broken something.
BAT does not actually have a section for the Self Stationary planes so you have to create them.
Add your lines to the air.ini for your aircraft in WAW:
[AIR]
//you can disable a plane by putting two forwardslashes infront of it like in front of this line
//if you leave a line open, the game wont see the open line. use this to make navigating this page easier
//a plane can appear more than once in this list, but watch out because than can make troubleshooting harder later, and may cause other conflicts
//use the top area for your favourites, or for testing new installations
//arrange the lists below to your taste.
//This is the order that planes will appear in in your QMB, and other drop down lists.
//I put the 109E4 up first so it is close, but also so that the first thing to appear in your QMB is not " * " form the placeholder.

Then create two new sections at the end of your existing aircraft sections in the Stationary and technics.ini:
[Self_StationaryPlanes]

Hs126A_1_Spats vehicles.planes.Hs126A_1_SpatsStatic$Hs126A_1_Spats 1

Here they are in the image so you can see what I mean:
You should then be good to go.
Wishing you all the very best, Pete.
