is four times as sensitive as TACAN and VOR displays.

GLIDESLOPE SIGNAL
B.
Glideslope transmitter
1.
Produces a navigational signal which provides vertical guidance
for the pilot (glidepath) along the localizer approach course
NOTE: The ILS beam gradient (glideslope) is normally set for
a 3-degree glidepath. However, the angle may be set to other
gradients due to terrain or obstacle clearance and/or reception
requirements.
NOTE: “Glideslope” is defined as the descent angle assigned
to an approach for a given runway for the reasons stated above.
Normally the term is associated with the final descent angle of
an ILS or PAR approach. “Glidepath” is defined as that portion
of a precision approach where the glideslope intersects the
localizer beacon of an ILS or FAC of a PAR.
