T-6B PRIMARY INSTRUMENT NAVIGATION CHAPTER EIGHT
815. ARCING APPROACH
General. Establish the aircraft inbound on the final approach course.
Description. An Arcing approach makes use of an arcing maneuver to position the aircraft
inbound on the final approach course. Arcing approaches are normally identified by VOR/DME
or TACAN in the approach plate margin, meaning DME is required.
Arcing Speed. When executing Arcing approaches, maintain 150 KIAS until the lead turn onto
the final approach course has been made, or until 5 NM prior to FAF.
NOTE
Use Radial/Arc and Arc/Radial intercepts to make the turn onto
and off of the arc.
Procedure. The following procedures assume clearance for the VOR/DME Z or TACAN Z
RWY 13R (KNGP) approach (Figure 8-10) has been received and you are proceeding direct to
the IAF.
1. At the IAF:
a. TIME – Not applicable.
b. TURN – Turn in order to place the VOR needle at the 90º benchmark.
c. TIME – Not applicable.
d. TRANSITION – Comply with any altitude restrictions as required.
NOTE
On some approaches, the transition at the IAF could involve a
descent and/or a reduction in airspeed.
e. TWIST – Ensure the inbound course (143º) is set in the CDI.
f. TALK – Give the appropriate voice report if required.
2. Anticipate interception of the final approach course (referencing the tail of the VOR/DME
needle and the CDI) while on the arc. Remember, the turn onto final approach course is a 90º
intercept.
3. When within 5 NM of FAF, make a level or descending transition to BAC.
