DASSAULT AVIATION Proprietary Data
Lateral navigation mode
Lateral navigation mode (LNAV) is selected by pressing the LNAV pushbutton, which
displays a cyan dot (LNAV armed) or a green dot (LNAV engaged), and accordingly the
FMA displays a cyan/green L NAV symbol. When LNAV is active, the FD will provide
lateral command to capture and hold the active leg of the flight plan. When engaged, the
AP will follow this FD lateral command and the roll will be automatically limited to 28°.
LNAV can be automatically activated after a DIRECT TO a waypoint selection and after a
transition from ROLL / HDG / TRK to LNAV (for these last cases, the airplane trajectory
must be convergent to the considered flight plan leg).
When active, LNAV mode can be disengaged automatically by AFCS logic (e.g.
commutation from LNAV to LOC if APP was previously armed) or manually by pressing
the LNAV pushbutton or by selection of HDG or TRK mode.

Approach mode
Approach mode (APP) is selected by pressing the APP pushbutton on the GP. A cyan
light (APP armed) or a green light (APP engaged) is then displayed on the pushbutton
itself. Accordingly the FMA displays LOC and G/S cyan / green indications for a precision
approach (ILS) or a LNAV and VGP indication for a non-precision approach.
