Week 3: Flight Director System Flashcards
What does the flight director do?
Presents steering commands on the flight display in the form of command bars and cross hairs
What does the FMS do and what does it contain?
Controls the aircraft during the whole flight, part of the AF system and contains logic, control laws and flight plan
What does the FCS contain?
the FGS
What is mode logic and control laws and are they specific to each aircraft?
Software that controls the flight control system and is specific to each aircraft
What the 2 elements that the FGS has?
Continuous and discrete
Flight control laws are what type of element?
Continuous element
What does the FGS do?
compares the measured state to desired state and generates a command to lessen the error between them
What converts the FGS values into visual cues shown to the flight crew?
FD
Is it the software or hardwares responsibility for activating/deactivating the FD?
The software
What are the 2 categories of FGS modes?
Lateral and Vertical
Lateral modes control what?
Horizontal motion by rolling
Vertical modes control what?
Vertical motion by pitching
This mode is the default mode where the aircraft will hold a fixed roll angle and is always active
ROLL mode
This mode is used for precision approaches when the aircraft is attempting to capture or has captured the specified nav source and is selected manually by pressing on the FCP
APPR mode
This mode will force the aircraft to hold a pre-set heading and is selected on the yoke
Go Around mode
This mode will track a heading displayed on the PFD
HDG mode
This mode is used for en route non-precision approaches and will track and acquire the nav source displayed on the PFD.
NAV mode
What are the 5 Lateral modes?
ROLL, APPR, GA, HDG, NAV
What are the 7 Vertical modes?
PTCH, ALT HOLD, ALT SELECT, APPR, FLC, GA, VS
This vertical mode is the default operation where the airc. will maintain a fixed pitch angle
PTCH mode
This vertical mode will maintain the pressure altitude
ALT HOLD mode
This vertical mode will capture a preselect altitude
ALTS mode
This vertical mode is used for precision approach that will capture the glideslope
APPR mode
This mode will acquire and track and IAS or MRS by adjusting pitch and will ascen/descend
FLC mode
This mode will hold a pre-set reference pitch angle
GA mode
This mode will contain a specified vertical speed
VS mode
Which modes are independent modes?
APPR and GA
What is the most important device for relaying information to the flight crew?
PFD
