PROCEDURE TURN APPROACH
Reference: AIM, Chapter 5; NIFM Chapter 20.
Amplification A Procedure Turn approach is an instrument maneuver used to reverse
direction to establish an aircraft inbound on the intermediate or final approach course. Procedure
Turns are depicted by a "barb" symbol on the approach plates, which indicates on which side of the
outbound course to complete the turn (Figure 651). Headings are provided to reverse course
using a 45/180 degrees type maneuver. 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 as long as the Procedure Turn is
executed on the proper side of the outbound course and the "Remain Within" distance (normally
10 NM) is not exceeded. Some of the options are the 45/180 degrees course reversal, the racetrack
pattern, or the 80/260 degrees course reversal.
During the RI syllabus, only the 45/180 degrees course reversal will be practiced. Do NOT
execute a Procedure Turn when:
Radar vectors to the final approach course are provided.
A Holding Pattern is specified in lieu of a Procedure Turn (Figure 648).
Approach can be made from a properly aligned Holding Pattern (Figure 655).
The procedure specifies "No PT," no Procedure Turn (Figure 666).
The plan view does not depict a Procedure Turn "barb" symbol.
Procedure The following procedures assume clearance for the DAYTONA BEACH
INTERNATIONAL VOR or GPS RWY 16 approach (Figure 651) has been received and you are
proceeding to the IAF.
At the IAF, indicated by station passage, execute the 6 Ts:
TIME Not required; time of commencing an instrument approach is not
reported to the controlling agency.
TURN in the shortest direction to parallel the outbound course (336º).
TIME Start timing for two minutes outbound when wings level or abeam the
station, whichever occurs last.
In strong winds or at indicated speeds greater than 120 knots, you
may have to adjust outbound timing to comply with any "remain
within distance" associated with the approach. Normally, two
minute timing outbound will be sufficient.
