SPZ--8000 Digital Integrated Flight Control System
Radio Altitude Display -- The radio altitude is displayed in
D
in the lower right--hand corner of the EADI and indicates radio
altitude from 0 to 2500 feet. The radio altitude display resolution is
described in Table 4--4.
Radio Altitude Range
0 to 100 feet
100 to 1500 feet
Greater than 1500 feet
The display is blanked for altitudes greater than 2500 feet. When the
radio altitude data is invalid, the display is removed and a boxed
flag is displayed.
Localizer Pointer, Localizer Scale, and Rising Runway -- The
D
localizer pointer moves laterally along the localizer scale to display
localizer deviation whenever an ILS frequency is tuned. The pointer
is green if it is related to the on--side navigation source and it is
yellow if the cross--side navigation source is used.
When radio altitude is 200 feet, the localizer pointer changes to a
rising runway that starts to expand linearly with radio altitude. It
reaches maximum size at touchdown. If the radio altitude is invalid,
the localizer deviation is still displayed, but the runway does not
expand.
Inclinometer -- The inclinometer gives the pilot a conventional
D
display of aircraft slip or skid, and is used as an aid in coordinated
flight maneuvers.
Pitch and Roll Command Cue -- The command cue displays
D
computed steering commands to capture and maintain a desired
flightpath. The pilot must fly the symbolic aircraft to the cue. The cue
is removed if an invalid condition occurs in the flight director pitch or
roll channel.
IAS/Mach Reference Bug and Display -- The
D
reference bug moves along the airspeed scale and is controlled with
the IAS/MACH knob on the pilot's instrument remote controller. The
value of the bug is digitally displayed at the bottom of the scale.
Resolution is 1 knot for IAS and 0.01 for Mach. IAS or Mach
reference can be alternately displayed by pushing the IAS/MACH
PUSH CHG button on the instrument remote controller. The
power--up value for selected speed is 80 kts IAS.
