SPCA 40T

The SPCA 40T, also designated the SPCA VII,[1] was a mailplane built in France in the late 1920s. It was a high-wing monoplane of conventional layout with a thick-sectioned, cantilever wing.[1][3] The flight deck and cargo bay were fully enclosed, and the latter could be adapted to seat five passengers.[3][4] The fixed undercarriage consisted of divided main units with spatted wheels, plus a tailskid. Construction was of metal throughout.[1][2]

The two 40Ts were followed by a single example designated 41T with more powerful Salmson 9Nc engines that first flew on 12 December 1931.[1] Services Aeriens de Madagascar operated the 41T between Tananarive and Broken Hill (where the route connected with Imperial Airways).[2][4]

Eventually, the 40Ts were fitted with this same engine, at which time they were redesignated SPCA 218.[1]

gollark: Do you *know* the current solar angles?
gollark: Obviously you could shorten that to, well, "it's quite late here".
gollark: But I like numbers. I have a book on number theory open on my other screen.
gollark: If LyricLy says "hmm, it is 3AM here" that probably means something like more like "wow, my sleep schedule is currently quite far shifted from the societal expectations thereof" than "the sun is 62 degrees below the horizon".
gollark: What? You don't actually need to know where the sun is. You need to know some stuff derived from that *and* a bunch of other things; you can just use the derived data.
