Definition of "Überholung" in LW monthly strength reports

[Kari Lumppio]

Hello!

In the Luftwaffe monthly stregth returns there is also column Überholung.
(I speak of the format seen at mr. Holm's homepage - the original document is different?)

Reading some recent posts has raised some questions in my mind:

1) does Überholung include also planes having combat damages and needing repairs or normal maintenance (= major overhauls) only? What would be the damage percentages in this classification?

2) were planes recorded as sent for Überholung necessarily airworthy? Or could they be delivered also via railroad etc.?

3) why the respective column in the Zugang side is named Reparatur and not Überholung?

Is there any primary sources for these definitions?

For example: if a plane falls into this Abgang-Überholung category and was not airworthy then in my opinion that would constitute a valid victory for the opponent if damages were received in air combat.




Thanking in advance,
Kari
