Saab AJ and AJS 37 Viggen flight manuals (SFI)

This post is obviously completely unrelated to tanks and might actually be better under the Reference documents tab, but occasionally weird Swedish cold war byproducts come out of my archival research.

In the Swedish Air Force, a the flight manuals were historically called things like Fpl AJS 37: speciell förarinstruktion (“Aircraft AJS 37: special pilot’s instructions”, where “special” is used in the sense that these instructions are particular to this aircraft type), where speciell förarinstruktion was abbreviated SFI. There was usually one unclassified part and 2-3 classified ones. In the last year, the national military archives have kindly declassified most of these manuals for the strike version of the Saab 37 Viggen, the AJ 37 and its 90’s updated version, AJS 37. I’ve turned these into PDF files for your convenience. They are all in Swedish, of course – since the Viggen was never exported, they were never translated.

Fpl AJS 37 speciell förarinstruktion (SFI) del 1 (M7780-402291) (59 MB, PDF format)
Published by FMV:FLYG in November 1994. Open, unclassified. Contains a general technical description of the aircraft and most of its onboard systems without going into too many details on sensitive points.

Fpl AJ 37 speciell förarinstruktion (SFI) del 2 (M7780-400172) (58 MB, PDF format)
Published by FMV:FLYG in February 1975. Formerly classified secret, declassified on January 20th, 2016. Contains technical descriptions of sensitive onboard systems such as weapons, radar, countermeasures etc, as well as a description of some typical mission profiles. According to the index it should also contain five more chapters, but these were missing in the binder in the national archives. However, those same chapters are in the Fpl AJS 37 SFI above – albeit for a slightly updated version of the same aircraft.

Fpl AJ 37 speciell förarinstruktion (SFI) komplement del 3 (M7780-400173) (10 MB, PDF format)
Published by FMV:FLYG in July 1979. Formerly classified secret, declassified on January 21st, 2016. Contains aerodynamic performance charts of various kinds – acceleration, rate of climb, combat range, etc etc. The chapter on turn performance is missing.
