failure, preflight planning will be limited. The same glideslope and DH that apply to the standard

PAR also apply to the No Gyro approach. This information should be reviewed prior to any GCA.

Procedure

Review the PAR Procedures from Chapter 6. NoGyro Procedures are the same with the following

exceptions:

Make a specific request for a "NoGyro PAR" when you contact approach control.

Make all turns at standard rate until on final approach, then make turns at halfstandard

rate, unless instructed otherwise by ATC.

Roll into turns immediately upon hearing the words "turn right" or "turn left." Roll

wings level on receipt of the words "stop turn."

NOTES

1. The standby compass may be used for orientation during the No

Gyro approach. Use this compass only for orientation and not for

maintaining heading.

These same procedures can be applied to a NoGyro ASR if a

PAR is unavailable.

LOCALIZER APPROACH

Reference: NIFM, Part 5, Chapter 23, "Instrument Landing System," AIM Chapter 1,

"Instrument Landing System."

Amplification The Localizer approach makes use of a localizer transmitter, a component

of an instrument landing system, to provide course guidance to the runway centerline. The

localizer transmitter operates in the frequency range of 108.1 MHz to 111.95 MHz (odd tenths).

There are two types of Localizer approaches front course (Figures 79 and 710) and back

course (Figures 711 and 712). The back course signal is transmitted along extended runway

centerline, in the opposite direction of the front course. Course guidance can be received at a

distance of 18 NM from the transmitter at 1000 feet above the highest terrain along the course line

to 4500 feet above antenna elevation. Offcourse indications are reliable within 10 along course

out to 18 NM and within 35 out to 10 NM (Figure 75) unless otherwise indicated on the

approach plate.

The ILS or Localizer approach can be easily identified on IFR Enroute Low Altitude approach

charts with the "ILS approach" symbol. See the ILS approach "feather" into GULFPORT

BILOXI Regional Airport and NEW ORLEANS International Airport, Figure 77.
