SPZ--8000 Digital Integrated Flight Control System
Below is a brief description of the controller switch functions.
System Display Switch (SYS DSPL) -- This switch turns the ISDU
D
on, and selects the IRS from which data is displayed.
Display Select Switch (DSPL SEL) -- This switch selects the
D
parameters to be displayed on the selected IRS as follows:
— TEST -- This is a spring--loaded position that tests data display
and the annunciator lights.
— TK/GS -- This position displays current track and groundspeed.
— PPOS -- The pilot uses this position when on the ground, so the
present position can be entered. In this position the ISDU
displays present position.
— WIND -- This position displays the current wind velocity and
direction.
— HDG/STS (STATUS) -- The pilot uses this position to enter
aircraft heading. When in the ATT mode, the ISDU displays ATT
if the switch is in this position.
Brightness (BRT) -- This knob is used to set the level of display
D
brightness.
Keyboard -- The keyboard inputs data, i.e., present position. The
D
input data is displayed in the display area. The ENT and CLR keys
are used to enter (ENT) data into the system, or to delete (CLR) data
on the display.
Display -- The display area consists of 13 individual 7--segment
D
displays that show data input from the keyboard.
