Abstract

An enhanced modular avionics system for communication and processing in an air transport aircraft including a modular avionic cabinet having a first scsi bus for a first processor and associate memory wherein the first scsi bus extends across a first portion of the cabinet and a second scsi bus for connection to a second processor and associate memory which extends across a second portion of the cabinet where the first portion of the cabinet and the second portion of the cabinet together equal the entire cabinet and there is no overlapping between the first portion and the second portion. Also shown is an extended bus which extends the entire length of the cabinet. The extended bus is located a predetermined distance from the top edge of the cabinet, while the first and second buses are located in a parallel line with each other and with the extended bus, the same predetermined distance from the bottom edge of the cabinet.

Claims

1. An improved avionics electronic library system for use in an aircraft computer and communication system of the type having an aircraft data distribution network therein, the electronic library system comprising:

an electronic library system cabinet having a top side and a bottom side and having plurality of slots therein and said cabinet coupled with said aircraft data distribution network;

said cabinet having a first bus extending across and connecting each of said plurality of slots;

said cabinet having a second bus extending across a first subset of said plurality of slots;

said cabinet having a third bus extending across a second subset of said plurality of slot;

said first subset and said second subset having none of said plurality of slots in common and none of said plurality of slots are absent from the combination of both said first subset and said second subset; and

,

said first bus located a predetermined distance from said top side, said second and third buses are located said predetermined distance from said bottom side.

2. A modular avionics system for use in an aircraft computer and communication system of the type having an aircraft data distribution network therein:

the modular avionics system comprising;

modular avionics system cabinet, having a top side and a bottom side and having a first slot, second slot, third slot and fourth slot therein said cabinet coupled with said aircraft data distribution network;

said cabinet having a first bus extending across and connecting said first slot, said second slot, said third slot and said fourth slot;

said cabinet having a second bus extending across said first slot and said second slot, but not across said third slot and said fourth slot;

said cabinet having a third bus extending across said third slot and said fourth slot, but not across said first slot and said second slot;

said first bus is positioned parallel to said top side of said cabinet and at a predetermined top distance from said top side;

said second bus is disposed parallel to said bottom side of said cabinet and at a predetermined bottom distance from said bottom side;

said third bus is parallel with said bottom side of said cabinet and is located at said predetermined bottom distance from said bottom side; and

,

said predetermined top distance, and said predetermined bottom distance are equal.

3. An improved modular avionics system for use in an aircraft computer and communication system of the type having an aircraft data distribution network therein, the improved modular avionics system comprising:

a system cabinet having a top side and a bottom side and a plurality of slots therein, said cabinet coupled with said aircraft data distribution networks;

said cabinet having a first bus extending across and connecting each of said plurality of slots;

said cabinet having a second bus extending across a first subset of said plurality of slots;

said cabinet having a third bus extending across a second subset of said plurality of slots;

said first set and said second subset having none of said plurality of slots in common and none of said plurality of slots are absent from the combination of both first subset and second subset; and

,

said first bus located a predetermined distance from said top side and said second and third buses located said predetermined distance from said bottom side.
