J. Glide Slope Test
S 735-018
(1) Do the glide slope test:
(a)
Do the following steps for the system test.
(b)
Align the inertial reference system if not already aligned (AMM 34-28-01/201).
(c)
Set a frequency of 108.10 MHz on the No. 1 VHF NAV control panel. 1) Make sure the G/S flag and the LOC flag show in the standby
attitude/ILS indicator.
(d)
Set the output of the ramp test set to supply an on-course glide slope signal at a frequency of 334.7 MHz. 1) Make sure the G/S flag in the standby attitude/ILS
indicator goes out of view. 2) Make sure the glide slope pointer in the standby attitude/ILS indicator is in the center. 3) Make sure the glide slope scales show on the captain's EADI and EHSI. 4) Make sure the glide slope pointers on the captain's EADI and EHSI are in the center.
(e)
Adjust the output of the ramp test set to supply a glide slope down signal. 1) Make sure the glide slope pointer in the standby
attitude/ILS indicator moves in the down direction.
