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.
Jun 16, 2016 · Course Reversals. Holds, procedure turns and their siblings all have the same basic purpose: realign the aircraft with the final approach course. Except when they cant. There I was, bouncing along on the miss from Vandenberg, err, Tampa (Fla.) Executive, KVDF. My instructor and I were flying the published miss after a practice ILS to KVDF’s ...
Oct 20, 2018 · Some say it’s when you complete the course reversal; others say it’s when you’re established on the inbound segment. A quick check of the Pilot/Controller Glossary settles this by defining it as “that point of a procedure turn maneuver where course reversal has been completed and an aircraft is established inbound on the intermediate approach segment or …
How should a pilot reverse course to get established on the inbound course of the ILS RWY 9 if radar vectors to final or the three NoPT IAFs are not used? Make an appropriate entry to the depicted holding pattern at EXPAM. (Refer to Figure 249.) What waypoints are designated as fly-over waypoints?
Generally, the procedure turn we'll fly will be of the 45/180 variety in the lower left, above, where we fly outbound from the fix for a minute, then turn 45 degrees left or right—depending on what's charted—proceed for another minute, then turn 180 degrees in the direction opposite our 45-degree turn.Jun 16, 2016

What options are available concerning the teardrop course reversal for LOC RWY 18 approach to Lincoln? If a course reversal is required, only the teardrop can be executed. If an early missed approach is initiated before reaching the MAP, the following procedure should be used unless otherwise cleared by ATC.
What Is A "Back Course" Approach? When you fly a localizer back course approach (LOC BC), you're navigating to the runway using horizontal guidance off of a localizer system, but in the opposite direction that you'd normally use the localizer.Mar 24, 2018
Rule #1. Always (always!) put the localizer inbound front course under the omni-bearing selector (OBS). The OBS setting doesn't matter to the electronics on a localizer, but this is a good rule as we'll see a bit further down.Jun 8, 2016
The course line along the extended centerline of a runway in the opposite direction to the front course, or the localizer course for an ILS (instrument landing system). For an aircraft to approach the instrument runway from the end on which the localizer antenna is installed, the back course must be flown.
Short reply: IAF is Initial Approach Fix. It marks the start of the Initial segment of the approach. IF is the Intermediate Fix, which marks the start of the next, or Intermediate segment. For completeness, though not in yr question, the start of the Final segment is marked by the FAF or Final Approach Fix.Jun 8, 2004
The correct way to identify the missed approach point is by using 1.1 DME, which is 6.2 DME beyond the final approach fix. Notice they are not the same numbers. This type of approach is named LDA if not aligned within 3° of the runway centerline.Nov 13, 2013
At what point is the pilot authorized to descend below 5,300 feet when cleared to the AJCIZ waypoint from the west? 15 NM from the waypoint. - When arriving from the west, the IAP shows pilot must maintain at least 5,300 feet between 30 NM and 15 NM from AJCIZ.
Back Course Localizer Because you are closer to the localizer antenna, the course information is more narrow and can seem "sensitive." Just don't forget the switch that allows the flight director to get its mind right about the front course versus the back course.
In aviation, a critical area refers to a designated area of an airport that all aircraft, vehicles, persons or physical obstructions must remain clear of when one or more Instrument Landing Systems (ILS) are in use, to protect against signal interference or attenuation that may lead to navigation errors, or accident.
In “reverse sensing,” the instrument is displaying exactly what you're telling it to display. It takes some effort from the pilot to not become “reversed.” Where pilots get confused and think that the instrument is reversed is when the OBS is set to the reciprocal of the course they want to fly.Dec 23, 2015
In the real world, this wouldn’t have been a problem. One of two things would have happened. First, on going missed at KVDF, we’d have gotten at least one vector from Tampa Approach. It would have been to the east to get us headed away from KVDF.
I’ve been doing this a while, but I can count on both hands the number of times I’ve had to do a for-real procedure turn, with a few fingers left over. The simple reality is the radar environment we enjoy in the U.S. precludes much of the need for and drama of procedure turns. But that doesn’t mean we don’t need to be ready for them.
A holding pattern may be published/specified in lieu of a procedure turn as the preferred course reversal. Like the procedure turn itself, the hold usually is based on a final approach fix. As with any other hold, the distance or time specified must be observed.
Since ATC generally wants to be a step or three ahead of you, it’s not at all likely you’ll ever get into a situation like my instructor and I did—no way to get from where we were to where we wanted to be. That said, we often practice only holds or 45/180 procedure turns, and we rarely even think about teardrops or DME arcs.
Course reversals come in three flavors: the traditional procedure turn, the hold-in-lieu-of procedure turn (HILPT), and the teardrop (or penetration) turn.
Entry from the en-route environment is somewhat variable based on the details of that particular approach and your direction of flight. In general, though, it’s as simple as flying to the procedure turn fix either directly or via a feeder route, then turn outbound (often over 180 degrees). The rest of the procedure is as charted.
The rules are actually pretty clear about when to fly the thing.
Hopefully this settles the debate about how procedure turns are intended to be flown, and gives you some basis for educating pilots at your next hangar-flying session. Keep in mind though that pilots and controllers are all human, and not everyone does things exactly by the book all the time.
When preparing to fly a procedure turn, there are a couple critical pieces of data that should be briefed, since there can be quite a bit of variation in how procedure turns are defined. Here’s a handy decoder ring.
When you fly a localizer back course approach (LOC BC), you're navigating to the runway using horizontal guidance off of a localizer system, but in the opposite direction that you'd normally use the localizer. Navigation is very similar to a localizer-only approach, but with a few key differences.
You'll often find LOC BC approaches on runways with an ILS installed, but pointing in opposite direction. In Grand Forks, ND (KGFK), winds are predominantly out of the northwest. The ILS for KGFK's north-facing Runway 35L is also used to create a LOC BC approach to Runway 17R.
For pilots flying a LOC BC approach using a course deviation indicator (CDI) with an omni bearing selector (OBS), you must pay close attention to "reverse sensing" associated with the back course.
If you're lucky enough to fly with a horizontal situation indicator (HSI), flying LOC BC approaches gets significantly easier. The HSI combines a heading indicator with CDI needles. As long as you tune the front course for the localizer, you won't get reverse sensing.
Once you're established on a LOC BC approach, flying is as simple as any non-precision approach. You'll reference step down fixes and DME before leveling off at your minimum descent altitude (MDA).
When you fly an autopilot-coupled LOC BC approach, ALWAYS push the "back course button" if there's one installed for your autopilot system. By pushing this button, you're telling the autopilot to turn inbound on the back course instead of outbound. Here's the scenario...
