AUTOFLT SYS AFS Flashcards
AFS INCLUDES
FG
FLT GUIDANCE
FMS
FLT MGMT SYS
FE
FLT ENVELOPE
FCDC
FLT CONTROL DATA CONCENTRATOR
FG PROVIDES
LATERAL AND VERTICAL GUIDANCE
SPEED OR MACH CONTROL
IN ACCORDANCE WITH TARGETS
SEL BY FLT CREW
OR
MANAGED BY FMS
SELECTED TARGETS
FLT CREW SEL INPUT ON AFS CP
THESE INPUTS DIRECTLY TO FG FOR IMMEDIATE GUIDANCE RESPONSE
THIS IS CALLED SELECTED GUIDANCE
AFS CP IS SHORT TERM INTERFACE
MANAGED TARGETS
FLT CREW INSERTS THE FLT PLAN INTO MFD AHEAD OF TIME
FMS COMPUTES AND MANAGES THESE TARGETS FOR FG
THIS IS CALLED MANAGED GUIDANCE
MFD IS LONG TERM INTERFACE
LATERAL AND VERT GUIDANCE
EITHER SELECTED OR MANAGED INDEPENDENTLY OF EACH OTHER
HOWEVER MANAGED GUIDANCE NOT POSSIBLE WHEN SEL GUIDANCE USED
LATERAL
SEL. MGD
Selected. YES. YES VERTICAL
Managed. NO. YES
VERT SPD
CAN ONLY BE SEL
FMS
PROVIDES LONG TERM GUIDANCE ALONG ACTIVE FLT PLAN
FE
USED BY FG AND FLT CONTROLS TO PREVENT THE AIRCRAFT FROM EXITING THE ENVELOPE
FCDC
DETERMINES THE AUTOLAND CAPABILITY FOR THE AFS
INTERFACES THE AP FD A/THR WITH FWS TO ALLOW ASSOC ALERTS TO BE TRIGGERED
GENERATES MAINT MSG FOR FG AND FE
FCDC ALSO PERFORMS FUNCTIONS FOR FLT CONTROLS
