T-34C INSTRUMENTS

PRECISION APPROACH RADAR (PAR) A standard Instrument Approach Procedure in

which an electronic glideslope is provided. In this type of approach the pilot is provided with

course and altitude information. A PAR approach is a precision approach. (See Ground

Controlled Approach.)

PUBLISHED ROUTE A route for which an IFR altitude has been established and published,

e.g., federal airways, jet routes, area navigation routes, specified direct (feeder) routes.

PROCEDURE TURN (PT) A maneuver used to reverse direction to establish an aircraft on

the intermediate approach segment or final approach course of an instrument approach. The

outbound course, direction of turn, distance within which the turn must be completed, and

minimum altitude are specified in the procedure. However, the point at which the turn may be

commenced, and the type and rate of turn, are left to the discretion of the pilot.

RADAR ENVIRONMENT An area in which radar service may be provided.

RADAR IDENTIFICATION The process of ascertaining that a radar target is the radar return

from a particular aircraft.

RADAR VECTOR A heading issued to an aircraft to provide navigational guidance by radar.

RADIAL A radial is a magnetic bearing extending from a VOR, VORTAC, or TACAN.

RADIO MAGNETIC INDICATOR (RMI) A navigation instrument that indicates both

magnetic heading and magnetic bearing to a selected radio navigation facility.

REPORTING POINT A specified geographic location in relation to which the position of an

aircraft can be reported.

RUNWAY VISUAL RANGE (RVR) The horizontal distance a pilot will see down the

runway from the approach end. RVR is determined with electronic instruments and is reported

in hundreds of feet. RVR, in contrast to prevailing or runway visibility, is based on what a pilot

in a moving aircraft should see looking down the runway. RVR is horizontal visual range (NOT

slant range).

SHALLOW INTERCEPT Aircraft heading within 30 of the desired course and tracking

toward it. (Note: This definition applies to Primary Intrument training only.)

SHORT RANGE CLEARANCE A clearance issued to a departing IFR flight which

authorizes IFR flight to a specific fix short of the destination while air traffic control facilities are

coordinating and obtaining the complete clearance.

STANDARD INSTRUMENT DEPARTURE (SID) A preplanned, coded, air traffic control

IFR departure routing, preprinted for pilot use in graphic and textual form.

STATION A radio navigational aid (see NAVAID).
