Automatic Minimum Safe Altitude Digital DisplaySpecifications
This page is under construction and will have the I-phone and I-tablet minimum requirements for compatibility with the AMSADD software.
Definitions of MSA as perceived ATC, FAA, and AMSADD:
MSA is a common expression, used in various cases to denote an altitude below which it is unsafe to fly owing to presence of terrain or obstacles. An ICAO definition of the term "minimum safe altitude" as such does not exist.
MSA as used by Air Traffic Control is called Minimum Sector Altitude. The lowest altitude which may be used which will provide a minimum clearance of 1000 feet above all objects located in an area contained within a sector of 25 NM radius centered on radio aid to navigation. This altitude may be used under emergency conditions.
MSA as defined by AMSADD is similar to FAA definitions and generally means obstacle clearance of one thousand (1000) feet over flat terrain and two thousand (2000) feet over mountainous terrain including clearance above towers and other man made obstacles.
Interface of the AMSADD "final approach" feature to compliment government and other approach plate procedures:
While AMSADD does not replace FAA approved approach charts, the final approach feature of AMSADD including the go around procedure will follow the FAA approved charts, but are not intended to be the primary authorization to use for such approaches.
Finally, Initialization of AMSADD will be compatible with jets, high speed turbo props, and general aviation aircraft. During the initial setup of AMSADD, various factors can be entered into the AMSADD setup screen in regard to type of aircraft and other miscellaneous factors.
Who really invented GPWS?
