TM 55-6930-212-10
the selected airport had a glideslope of 2.7 degrees, the flight instrument in the cockpit and the verbal guidance shown on
the display would tend to guide the aircraft down a track that follows the lowest reference line. When the aircraft comes
within range of the GCA/ILS display, each part of the display shows the aircraft position and track. Flight director
instructions appear on the screen as appropriate. These can be read to the pilot or copilot by the instructor operator.
8-17.
A maximum of five lines of precision approach radar (PAR) commands can be displayed below the glidepath plot
and left of the azimuth plot. If a line contains no information useful to the problem, the line is blanked, and the lower
lines are moved up. PAR commands consist of the following:
a.
Line 1, a variable field, consists of short statements concerning the progress of the aircraft in the PAR mode.
The message is displayed for 30 to 60 seconds, then the line is blanked. Variable field messages consist of:
Approaching glidepath
Begin descent
At decision height
Over approach lights
Over landing threshold
b.
Line 2 course information messages consist of:
Well left/right of course
- within 1.5º
On course
- within .5°
Slightly left/right of course
- within 1º
c.
Line 3 turn to heading information messages.
d.
Line 4 glidepath information messages consist of:
Well above/below glidepath
- within 0.42º
On glidepath
- within 0.14
Slightly above/below glidepath
- within 0.28º
e.
Line 5 consists of touchdown distance information. Distance in nautical miles to touchdown is expressed in
mixed numbers, with fractional readout updates in 1/4-mile increments.
8-18.
Facility-centered approach plot data is provided in table 8-5. Landing area beacon data is provided in table 8-6.
8-19.
EXTERNAL LOAD OPERATIONS.
8-20.
Four types of external loads can be simulated: light load, high-density (HD) load, aerodynamic load, and tandem
load. Six different loads are simulated.
(See table 8-7.) Information about each load is shown on one of the six load meter display pages. (see figure 8-7.)
These pages show the CRT page number, load number and type, and load location (latitude/longitude). The load
heading is indicated for both tandem and aero loads.
