ii.

Penetration including an Arcing Maneuver

When turning 90 onto an arc from a radial using SRT, the amount of lead (in

nautical miles) should be 0.5% of groundspeed. Do not exceed 30 AOB or

SRT, whichever occurs first. For 180 KIAS, use 1.2 NM lead as an

approximation since 30 AOB will give less than SRT.

NOTE

Some high altitude approach charts have penetration instructions

printed in the profile view of the approach chart. Review and

comply with all printed instructions.

Once established inbound, comply with the remainder of the Low Altitude

Instrument Approach procedures (paragraph 623.)

NOTE

High altitude approach charts do not contain landing minimums for

category B aircraft. T34s should use category C minimums.

GPS PROCEDURES

Reference: AIM Chapter 1, KLN 900 Pilot's Guide, T-34C NATOPS

Description. The T-34C has a panel mounted KLN900 GPS system consisting of a

sensor/navigation computer, a database card and an antenna. This system is used to conduct non-

precision instrument approaches based on satellite transmitted positioning information.

General. Prior to conducting any GPS approach training it is essential that the student read

the T-34C NATOPS section 19.8 (Global Positioning System) and be thoroughly familiar with

the components and operation of the KLN900 system. The GPS is considered a supplemental

navigation system and will not be used as a sole source of IFR navigation. All aircraft SHALL

have a operable TACAN/VOR while conducting IFR operations. While the GPS system does

provide the capability to conduct GPS Arcing approaches, GPS Standard Instrument Departure

(SID) procedures and GPS STAR procedures they will not be studied in this phase of training.

Student training will only be conducted utilizing radar vectors to the final portion of a stand-alone

or overlay GPS approach.

NOTE

Students must be familiar with the Turn-on and Self-Test Page

functions of the GPS at initial power up in order to verify correct

initialization and position data.
