Components and Characteristics of the Instrument Landing System (ILS)

At fields where no authority exists, such as a tower or

ground control, remain behind the critical area hold short

line if an approach is known to be in progress.

CAUTION: Invalid (phantom) glideslope signals can be

inadvertently projected in the area of the glideslope beam

and in an area behind the antenna (back course).

Do not accept a glideslope indication as valid when you are

not on a published portion of the approach and at an

altitude and position where you anticipate intercepting the

glideslope.

signal that intersects the localizer on an _________ approach or is

provided by ________ when established on the FAC of a PAR approach.
