Aircraft Operations

Part II — Section 2, Chapter 1

2) the GNSS equipment must not be used during departure;
b) the database contains the required transitions and departures. Databases may not contain all of the transitions or
departures from all runways, and some basic GNSS receivers do not contain standard instrument departures
(SIDs) in their databases at all; and
c) terminal RAIM alarm alert limits are automatically provided by the receiver (terminal RAIM alarm alert limits
may not be available unless the waypoints are part of the active flight plan).
1.4.1.2 Some FMC installations may not provide the terminal RAIM alarm alert but should provide an equivalent
capability appropriate to the operation.
1.4.2 Equipment set-up
1.4.2.1 The basic GNSS receiver must be selected to the appropriate mode for use in departure, as indicated for
the departure procedure (for example, the charted procedure may indicate that terminal mode is appropriate if departure
mode is not available, see 1.4.1.1) with CDI sensitivity of ±1.9 km (1.0 NM).
1.4.2.2 The departure navigation routes must be loaded into the active flight plan from a current navigation
database in order to fly the published SID. Certain segments of a SID may require some manual intervention by the
pilot, especially when the aircraft is radar vectored to a track or required to intercept a specific track to a waypoint.
1.4.2.3 Some FMC installations will rely on a combination of indications and situation information on electronic
map displays and primary flight displays, in conjunction with required operating configurations (for example, conduct
of procedures using the flight director), providing equivalency to conduct of the operation based upon the CDI.
1.4.3 Straight departures
Where the alignment of the initial departure track (α < 15°) is determined by the position of the first waypoint located
after the DER, there are no unique requirements for the basic GNSS receiver.
1.4.4 Turning departures
Turns are specified as a “turn at a fly-by waypoint”, “turn at a flyover waypoint” or “turn at an altitude/height”. For
some systems, turns at an altitude/height cannot be coded in the database, and in this case, such turns must be executed
manually.
