The PRIMUS EPIC LOAD 27.2 version also presents the Next Generation Flight Management
System (NG-FMS) functionality, previously introduced in LOAD 27.1, and new operational
functions with system improvements based on field data which correct deviations found during
aircraft operation and test campaigns in order to improve the aircraft operation.
EPIC LOAD 27.2 improves the existing FMS functionalities and it is a requirement to enable the
following new optional features that will be offered through dedicated Service Bulletins to the
customer:
– Volumetric Weather Radar (RDR 4000) which is an optional system that also requires full
set of DU-1080 HW3 configuration. The new system will work with INAV or classic Multi-
Function Display (MFD) format.
– Charts and Maps that is an optional function that lets the pilot view terminal charts on the
Multi-Function Display (MFD), and to manipulate the chart for optimal viewing.
(2) OBJECTIVE
This Service Bulletin introduces PRIMUS EPIC software LOAD 27.2 PN PS60003259-0308.
(3) EXPECTED BENEFITS
PRIMUS EPIC LOAD 27.2 presents an optimized Flight Management with better performance
and gains using new features: Volumetric Radar and Charts and Maps. These new features will
offered through dedicated Service Bulletins.
This new LOAD version has improvements on the following systems: Configuration Monitor
System (CMS), Electronic Display System (EDS), Automatic-Flight Control System (AFCS), and
Landing Gear System (LGS).
Before LOAD 27.2, the aircraft was capable of transmitting AHEAD data only in flight phases
(taxi, takeoff, cruise, approach, and roll out). PRIMUS EPIC LOAD 27.2 will permit transmitting
AHEAD data when the aircraft is on ground (preflight phase).
(4) REVISION HISTORY
REVISION 01: This revision has been issued to include aircraft in the SB effectivity, update
the CMC LDI Database PN, and create PART II.
REVISION 02: This revision has been issued to Include aircraft SNs 17000711 and
17000723, update expected benefits related to AHEAD data when the aircraft
is on ground, update ECL tool version, update ATC part number, included
information related to NG-FMS TOLD and include optional procedure in case
of NIC 2 fails to load.
REVISION 03: This revision has been issued to include aircraft SNs 17000549, 17000553,
17000556, 17000557, 17000558, 17000568, 17000569, 17000576,
