Aircraft Upgrade Paths

[donnie_1974_texas]

How does the game know what type of aircraft an airgroup can accept, especially with PDU on?

For example, IJ Navy transport groups can only accept Thora, Tina, Mavis, and Tabby transports...but when I look in the editor I notice that each of these only upgrade to themselves.

IJ Army - your choices are always the army fighters it appears.

IJ Navy - same thing - you can't upgrade an Zero daitai to Franks.

British fighters, US fighters, etc all hold true to this. But why? I see no rationale in the editor when looking at the aircraft data.

Hi all,

Here is a list I made long ago for Japanese:

Well, it's historical accuracy, you know...

Well, it's historical accuracy, you know...

Especially with PDU ON.

The slot the Zekes are in are hard-coded for carrier planes as are the Claudes.
They cannot upgrade to other than carrier planes for this reason.
If you use the editor to put Army planes in the exact same slots, they will then become "carrier planes", and void historical-correctness.
