4. Load 12 requires S242T102-552 hardware. Load 14 is available. Software loadable.

5. Due to parts obsolescence, 100K disk flight management computers (FMC) will not be supported by Honeywell after December 1999.

6. Current-delivery 200K FMCs have operational software PS4052520-126, -127, -161, and -162. Hardware part numbers are S242T102-226, -227, -330, and -331.

7. An upgraded PIP version is planned. Software loadable. Pegasus upgrade requires hardware and wiring changes for Future Air Navigation System (FANS) functionality.

8. No upgrade is considered necessary, but if an operator considers the display anomaly significant, an update to the Pegasus FMS is available.
