As I said Angus, Issy tries to put any spin he can on spark plug fouling.
A 6-7 hr flight, most of the time over enemy territory. Prudence would dictate that the plugs would be changed to ensure that the a/c would return safely. Do race cars change their plugs after practice? Sure they do. Logical practice it is.
German a/c, over 'friendly' territory with a flight time of 1-2 hrs can land if the engine goes 'sour'.
re 109 engine change times
Yes! The 605 installation in the 109 is very good for motor changes! However, 20mins would be an exceptional time . You could only do this with a fully-cowlled and prepared engine, all ready like an F1 pitstop! A normal engine-change with a motor in a crate and equipment available would take 3 men around 8hrs, IMO.
The complete motor can be easily removed. However, it takes alot of time to dress the replacement motor with all the ancillarys from the old motor. So, if you had spare motors and cowlings and ancillarys etc, you could do a quick-change. (my bold)
This, by schwarze man, who has no agenda, unlike a couple of other here, is from a post at
http://pub157.ezboard.com/bluftwaffeexperten71774As usual, Issy give the exception, not the typical/normal, in his attempts to show how
uber Germany was.
