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.
Review the PAR Procedures from Chapter 6. NoGyro Procedures are the same with the following
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."
1. The standby compass may be used for orientation during the No
Gyro approach. Use this compass only for orientation and not for
These same procedures can be applied to a NoGyro ASR if a
PAR is unavailable.

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