Although Bomber Command pilots might have had their MPH ASIs swapped for knots ASIs on 1^st April 1945, I thought it might be worthwhile checking what the guy in the back was doing.  I looked at the log and chart of Fg Off D Pybus, an RAF Navigator on No 463 Australian Lancaster Sqn in 5Gp flying from RAF Waddington, Lincolnshire on his 8^th Op to Bremen on 6^th Oct 1944 and on his penultimate 31^st Op to Nordhausen on 4^th April 1945.  On both trips the final leg was from the east coast of The Wash to Waddington.

In October 1944 he logs the distance as 47, which ties in with the stature miles scale on his chart.  On 4^th April he logs the same distance as 40, which ties in with the minutes of arc scale along the meridian.

Apart from anything else, can you imagine the comments from this largely Australian crew with 30 successful ops behind them when the dear old RAF expected them to change from Statute to Nautical miles for their last two ops on the squadron?  Note the statute mile scale on the PM1 chart also runs up a meridian but it keeps running from 0-50.
