the sym bol air craft pres ents the re la tion ship of the se lected course
to the air craft.
For an ILS ap proach, tune the nav i ga tion re ceiver to the de sired
fre quency. For LOC op er a tion, the se lected course pointer should
be set to the in bound lo cal izer course. The glideslope pointer will
de flect into view af ter a 2 to 12 sec ond de lay, if a us able
glideslope sig nal is re ceived. The glideslope pointer in di cates the
