Unlike HILPT or teardrop course reversals, pilots are given discretion in how they fly a traditional procedure turn. The 45/180 reversal is what’s depicted on government and Jeppesen charts, but other common variations include an 80/260 reversal, a teardrop, or a racetrack.
Full Answer
Number 6 may be the standard of course reversals. Many flight schools and instructors have different methods of making the standard procedure turn, and the FAA leaves the method selected to the pilot with one exception – the side of the course that is protected for the maneuver.
Entry Procedures — An example of a course reversal entry that is very different from U.S. procedures followed by a discussion of how ICAO Doc 8168, Vol 1 (PANSOPS) expects you to entry a course reversal just about everywhere in the world.
This approach has changed since then, it is now a "Racetrack Procedure" but back then it was as depicted, at 45°/180° course reversal. How would you enter this procedure turn? [Air Force Manual 51-37, ¶6-11] A parallel procedure turn entry may be used any time.
When a teardrop procedure turn is depicted and a course reversal is required, unless otherwise authorized by ATC, this type of procedure must be executed.
A teardrop procedure or penetration turn may be specified in some procedures for a required course reversal. The teardrop procedure consists of departure from an initial approach fix on an outbound course followed by a turn toward and intercepting the inbound course at or prior to the intermediate fix or point.
The 45/180 reversal is what's depicted on government and Jeppesen charts, but other common variations include an 80/260 reversal, a teardrop, or a racetrack. These are certainly allowed, but the rules aren't quite as lenient as they might seem.

Procedure Turns. A procedure turn is the maneuver prescribed when it is necessary to perform a course reversal to establish the aircraft inbound on an intermediate or final approach course. The procedure turn or holding in lieu of a procedure turn is a required maneuver.
There are three generally recognized maneuvers related to the reversal procedure, each with its own airspace characteristics:i. A 45°/180° procedure turn. ... ii. A 180°/260° procedure turn. ... iii. A base turn.
Gucci Pilot Pattern Altitude Flying a procedure turn shaped like a holding pattern is not holding. If there were just a PT barb on the approach, what you are saying is correct, you can do any kind of reversal you want as long as you stay on the other side.
You can see on the profile view that the procedure turn altitude floor is 3,000 feet. That means you can descend from 6,000 to 3,000 feet after crossing ZACKS outbound, and then down to 2,100 feet after established inbound.
When the approach procedure involves a procedure turn, a maximum speed of not greater than 200 knots (IAS) should be observed from first overheading the course reversal IAF through the procedure turn maneuver to ensure containment within the obstruction clearance area.
"a barbed arrow indicates the maneuvering side of the outbound course on which the procedure turn is made" That only means the procedure must be flown on the east side of the outbound course. It does not tell you which way to turn after flying 039 degrees.
Description. In turning flight, the number of degrees of heading change per unit of time (usually measured in seconds) is referred to as the rate of turn. By definition, a rate one or standard rate turn is accomplished at 3°/second resulting in a course reversal in one minute or a 360° turn in two minutes.
200 knotsWhen the approach procedure involves a procedure turn, a maximum speed of not greater than 200 knots (IAS) should be observed from first overheading the course reversal IAF through the procedure turn maneuver to ensure containment within the obstruction clearance area.
Some of the options are the 45/180 procedure turn itself, the racetrack pattern, the teardrop procedure turn or the 80/260 course reversal. The absence of the procedure turn barbed arrow in the plan view means indicates that a procedure turn is not authorized for that procedure.
Course reversals come in three flavors: the traditional procedure turn, the hold-in-lieu-of procedure turn (HILPT), and the teardrop (or penetration) turn. Regardless of the type of course reversal used, they all exist for the same basic reasons: allowing arriving aircraft, when necessary, to reverse direction and get established inbound on an initial, intermediate, or final approach course. They also give arriving aircraft an opportunity to lose excessive altitude while remaining within a defined area.
Last, look for where the thing ends. The procedure turn completion altitude is found at the end of the descending inbound line. (Not shown here.)
Timing of procedure turns can be a reference for spacing, but should not be followed blindly. Higher performance aircraft, strong winds aloft, or a shorter than usual procedure turn distance can cause a timed procedure turn to depart the protected airspace.
A common notion about procedure turns is that pilots are permitted to fly the course reversal however they choose, so long as they remain within the procedure-turn distance. Unlike HILPT or teardrop course reversals, pilots are given discretion in how they fly a traditional procedure turn. The 45/180 reversal is what’s depicted on government and Jeppesen charts, but other common variations include an 80/260 reversal, a teardrop, or a racetrack. These are certainly allowed, but the rules aren’t quite as lenient as they might seem.
ICAO says "the 45°/180° procedure turn is an alternative to the 80°/260° procedure turn unless specifically excluded," you would be wise to use the 45°/180° if there is any kind of wind. Example.
The 80°260° gives the pilot very little room to adjust for winds. If given a choice, any course reversal should be preferred to the 80°/260°. In the example shown you should avail yourself of the full 3 minutes outbound allowed to give yourself enough time to intercept the course inbound.
A racetrack procedure consists of: a turn from the inbound track through 180° from overhead the facility or fix on to the outbound track, for 1, 2 or 3 minutes ; followed by. a 180° turn in the same direction to return to the inbound track.
This straight leg is timed. It is: 1 minute from the start of the turn for Category A and B aircraft; and. 1 minute 15 seconds from the start of the turn for Category C, D and E aircraft; and. a 180° turn in the opposite direction to intercept the inbound track.
Normally a racetrack procedure is used when aircraft arrive overhead the fix from various directions. In these cases, aircraft are expected to enter the procedure in a manner similar to that prescribed for a holding procedure entry with the following considerations:
[Jeppesen Airway Manual Approach Chart Legend] The approach design can be determined from the bottom-left corner of the procedure. The absence of a PANS OPS or TERPS margin notation means the instrument approach design criteria is either unknown or the chart was dated before 21 NOV 03.
If a speed restrictions is published at Leoni, the aircraft will slow to comply with the published speed.
Overhead maneuver patterns are developed at airports where aircraft have an operational need to conduct the maneuver. An aircraft conducting an overhead maneuver is considered to be VFR and the IFR flight plan is canceled when the aircraft reaches the initial point on the initial approach portion of the maneuver.
If ATC has assigned an altitude to an aircraft that is below the TAA minimum altitude, the aircraft will either be assigned an altitude to maintain until established on a segment of a published route or instrument approach procedure, or climbed to the TAA altitude. Circling.
Air traffic will assign an altitude to cross the waypoint/ fix, if no altitude is depicted at the waypoint/fix, for aircraft on a direct routing to a STAR. Air traffic must ensure obstacle clearance when issuing a “descend via” instruction to the pilot.
The procedure turn is not required when the symbol " NoPT " appears, when radar vectoring to the final approach, when conducting a timed approach, or when the procedure turn is not authorized.
A procedure turn is the maneuver prescribed when it is necessary to perform a course reversal to establish the aircraft inbound on an intermediate or final approach course. The procedure turn or holding in lieu of a procedure turn is a required maneuver.
The maneuver must be completed within the distance and at the minimum altitude specified in the profile view: A procedure turn barbed arrow indicates the direction or side of the outbound course on which the procedure turn is made. Headings are provided for course reversal using the 45 degree procedure turn.
The maneuvers are required when it is necessary to reverse direction to establish the aircraft inbound on an intermediate or final approach course. Components of the procedure are depicted in the plan view and the profile view. The maneuver must be completed within the distance and at the minimum altitude specified in the profile view:
The procedure turn is referenced in Federal Aviation Regulation (FAR) 91.175 and in Aeronautical Information Manual (AIM) Chapter 5-4-9 for those readers who would like additional information on the topic. Procedure turns are often confusing to pilots, so I am hoping this article will provide clarification.
The controller’s handbook (when followed) states that whenever a controller gives radar vectors, it should be specified with the reason for the vector when giving the first vector to the pilot.
Paul also noted the following situations where procedure turns are not required: 1) When the symbol “No PT” is depicted on the initial segment being used. 2) When receiving radar vectors to the final approach course. 3) When conducting a timed approach from a holding fix.
Good pilots are always learning as Paul, a blogger on Ask a Flight Instructor, noted when he recently learned something new about TAA approaches, procedure turns and how they are charted – especially on the Jeppesen charts. To make a long story short, Paul was recently flying and made a procedure turn mistake.
