ARCING APPROACH

Reference: NIFM Chapter 20, "Low Altitude Approach Procedures"; and Chapter 21, "Tactical

Air Navigation (TACAN)."

Amplification 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. When arcing to

final, DME is required, but the margin identification may not require DME if an arcing maneuver

is depicted in addition to a Procedure Turn to establish the aircraft on final approach course

(Figure 666). The term "No PT" on the arc specifies the Procedure Turn will not be flown by

aircraft using the arc for the approach.

Arcing Speed Rules

When executing Arcing approaches, maintain normal cruise speed until 5 NM from

the FAF.

If holding at the IAF, and cleared for the approach:

Accelerate to normal cruise airspeed until 5 NM from the FAF.

Intercepting the Initial Approach Course

When clearance for the approach is issued, ATC expects an immediate turn in the

shortest direction to intercept the initial approach course upon reaching the IAF.

Clearance for the approach does not include clearance for the holding airspace.

However, normal lead points may be used to intercept the course (case A,

Figure 658).
