T-45C TS & ADV BIFP-08
GCA/ILS Procedures
MOTIVATION
Ground-controlled approaches (GCAs) are important to
you because they are one of the most precise means
available for recovering an aircraft under IFR conditions.
You will receive many hours of hands-on practice in
GCAs because of their importance and because they
require use of virtually every basic instrument maneuver
you have learned. Knowing when and how to execute a
proper missed approach for GCAs is the final step in
becoming comfortable with precision instrument
approaches. This lesson will also review the ILS
components introduced in INav, and ILS flight
procedures used in the T-45C. The requirement for you
to be able to fly an ILS approach with precision is
important because the only precision approach available
at civilian and Air Force fields where you may have to
land is the ILS approach. NAS Meridian is the only field
in the normal operating area that has GCA capability.
The approach of choice in emergency or instrument
conditions at civilian and Air Force fields is the ILS
approach. Thorough knowledge of ILS components and
procedures is the first step in achieving the needed
precision.
OVERVIEW
At the completion of this lesson, you will be able to
identify similarities and differences between precision
approach radar (PAR) and air surveillance radar (ASR)
GCAs, and will have reviewed the basic components of
the ILS approach system and procedures. You will be
aware of the communication requirements and be
familiar with the scan techniques involved. You will also
be able to identify the decision points and procedures for
performing missed approaches.
