• A SID can only be replaced with another procedure and cannot be
deleted. The linked portions of an arrival can be deleted via the
ARRIVAL page. In both cases, the discontinuity depends upon the
changed procedure. Linked flight plans or procedures can be deleted
under the same operation for deleting waypoints. This operation does
not cause discontinuity.
• The INTERCEPT function does not create a discontinuity before or
after the intercept point. When choosing the heading to intercept
option, a fly heading select leg is inserted that disengages the FMS
when the leg is sequenced.
A discontinuity can be deleted pressing DELETE key and adjacent Line
Select Key.
ACTIVE WAYPOINT/LEG NAVIGATIONAL DATA
The following data defining the active leg and to navigate to the active
waypoint are computed and displayed on the HSI and on the MAP and
PLAN formats of the MFD:
• Desired Track, displayed by the CDI arrow and below the primary
navaid annunciator
• Cross-Track Distance, displayed by the CDI deviation bar
• TO/FROM flag
• Active waypoint identifier
• Horizontal Distance to the active waypoint in nautical miles
• ETE (Estimated Time Enroute) in minutes or hours+minutes
• RNP (Required Navigation Performance) in nautical miles
FMS INITIALIZATION
The FMS has to be initialized before each flight in accordance with
theprocedure reported in the RFM/QRH (“FMS Operation Normal
Procedures – Pre-Departure Operations”).
The FMS initialization consists of the following tasks:
• POSITION Initialization
• FLIGHT Initialization
• PERFORMANCE Initialization
After landing without power shutdown, the Position and Active Flight Plan
data are retained, but Performance Initialization data must be re-confirmed
before take off.
