A rare poor shot I took a few years back of 10717 – at the Greenwood Military Aviation Museum in Greenwood, Nova Scotia

A derivative of the Britannia.

Among the changes they opted for piston engines instead of turboprops.

It was also unpressurized which saved weight and improved the endurance.

I should have thought that being restricted to a cruising altitude of around 10,000 feet(for passengers to breathe) would have caused a higher fuel burn with less endurance.

I should read the descriptions a little more carefully! According to the Greenwood museum it was the use of piston engines that really made a difference to endurance. www.gmam.ca/argus--cp-107-.html
The Canada Aviation and Space Museum has a similar narrative

Thanks. I've got Britannia on the brain.
Being military the individual crew members would have oxygen available and could go to the maximum service altitude. That it would do more-miles-per-gallon on 100 octane gasoline fed piston engines than AVTUR fed turboprops is intriguing. Clearly fuel costs were not a concern.

Would need speed to get to the patrol area, but once there would loiter at low altitude. Piston engines more efficient at low altitude?

I seem to recall something about the Nimrod loitering on two engines, if true, could the Argus do the same or would restarting be a problem and could this also be easier with a piston engine?
