FSX Lockheed SR-71 Blackbird SRX2012 Update 4N

Complete with Base ModelJump to: Screenshots | Comments | File Details

Alphasim SRX2012 SR71 freeware for FSX Deluxe SP2 and Acceleration. Previous "update" zip files distributed for this model not needed. The six original installation files supporting Deluxe only are required by all: SRX20121.ZIP, SRX20122.ZIP, SRX20123.ZIP, SRX20124.ZIP, SRX20125.ZIP, SRX20126.ZIP. This update will convert Base Deluxe to Acceleration for those using that version. Deluxe users will also have latest changes. Open the README.txt file for changes and installation instructions for Deluxe and Gold/Acceleration. By Paul R. Varn.

Changes since last update:

  • Mostly cosmetic changes to some gauges.
  • Checkride gauge is formatted and resized to be more readable.
  • IAS set bug added to air speed indicator.
  • Note: As is common with all FS aircraft. The set IAS and actual speed will only match in level flight due to pitot tube angle of attack error. This is not a defect in the model, gauge, or FS.
  • Additional autothrottle smoothing added to both Deluse and Acceleration versions during descent.
  • Small error corrections to the logic of several gauges.
  • The forward bypass closed check at Mach 2.6 has been made slightly more forgiving.
