After having had several close looks at Peter Cornwell's big book I am able to add that this book and its loss figures do NOT cover the Norwegian Campaign. The loss statistics cover the fighting over continental Western Europe ("Poney War", September 1939-9 May 1940 and French Campaign 10 May-24 June 1940), sometimes over the UK or over British waters, e.g. when German reconnaissance aircraft were caught over the UK and around it.

The Campaign in Norway is NOT included.

It could be considered obvious as the title of the mentioned book reads "The Battle of France Then and Now", aka TBOFTN or TBFTN, which doesn't include Norway, so you may call me a fool but I wanted to be quite sure. Besides, the Polish Campaign is not included either even though it took place in September 1939.

So we need not lower the German (or Allied) loss figures in order to take the Norwegian Campaign into account and obtain the pure "Battle of France" figures. They are pure already. As author Peter Cornwell explained numerous aircraft from all countries were heavily damaged but they were not taken into account when calculating the losses, even if they were written off (mostly in the rear) eventually. For both the German and the French air forces this adds a few hundred aircraft losses to the known totals.

Just a small remark on the side: from the historical point of view it is generally agreed that the period September 3-June 9 was the "Phoney War", aka "waiting period" or initial period, during which there was a certain amount of aerial activity with about 70 French fighter victories (not couting AAA successes). The French Campaign (FC) or Campaign in France (but it took place in the Netherlands and in Belgium too so FC is better) began with the all-out German offensive on May 10,1940. The BATTLE OF FRANCE was the second part of the FC, starting on June 5 (after 26 days) with the second German offensive towards the deep French territory, crossing the Somme and Aisne rivers first. It ended after 20 more days with the French-German cease-fire on June 25, 0.35 hrs, the German army having reached the Atlantic coast.
