INTRODUCTION
The Falcon 2000EX EASy Automatic Flight Control System (AFCS) is composed of:
- 2 Flight Director (FD) and 2 AutoPilot (AP) systems,
- 1 Thrust Director (TD) and 1 Auto-Throttle (AT) systems, 2 Yaw Damper (YD) and 2 Mach
Trim (MT) systems.
The AFCS elaborates orders in path and roll axis. These orders are displayed on the Attitude
Director Indicator (ADI), on the Head-up Guidance System (HGS, optional), and identified as
Flight Director (FD) orders.
The AFCS elaborates also a thrust order, displayed on the ADI, on the HGS (optional), and
identified as Thrust Director order.
When AP and AT are engaged, electric servo-motors are connected to:
- the flight controls via a clutch, so that the airplane will follow the FD orders,
- the power levers cables so that the engines will follow the TD orders.
Flight Director (FD) and AutoPilot (AP) can operate in:
- basic mode (ROLL and PATH),
- superior modes:
o Lateral NAVigation (LNAV),
o Heading / Track (HDG / TRK),
o APProach (APP),
o ALTitude (ALT),
o Altitude SELection (ASEL),
o CLimB (CLB),
o Vertical Speed (VS),
o Vertical NAVigation (VALT, VCLB, VPTH, VASEL, VGP),
o Glide Slope (GS).
Thrust Director (TD) and Auto-Throttle (AT) can operate in:
- speed / Mach mode,
- thrust mode.
The FD can also operate in the following specific modes:
- Go-Around (GA),
- windshear (not available).
The Automatic Flight Control System (AFCS) also automatically trims the airplane in pitch and
compensates for pitch variation during deployment of slats, flaps and airbrakes.
Whatever vertical modes selected, when AP is engaged, pitch is automatically limited to +/-
20°.
