Question: AP ammo on Aircraft

[RetLT]

I recently played a scenario in which a Spitfire used up most of its MG ammo and all of the HE ammo for its 20mm cannon.

It still had 2 AP rounds listed for the cannon so I had it target some tanks. The Spitfire made 3 separate passes but never fired the AP ammo for the cannon.

Does the weapon system stop working once all of the HE ammo is gone? I actually have a save of one of the passes if needed.
