what is the back course hold switch

RE: What does the Backcourse Hold Switch do? Backcourse simply means that you track a localizer by turning opposite of what you would on a normal ils. It uses reverse sensing, so, lets say you are on the ILS rwy 17L approach, then say rwy 35R has a back course.

What is a back course approach (Loc BC)?

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. Navigation is very similar to a localizer-only approach, but with a few key differences.

Can you use a back course signal for approach?

Keep in mind, just because a back course exists, doesn't mean you should use it. As stated in the FAA's AIM, "do not use back course signals for approach unless a back course approach procedure is published for that particular runway and the approach is authorized by ATC."

Do back-course final approaches require NDBs or outer markers?

Accordingly, you can expect most localizer back-course final approach fixes to utilize intersections with a nearby VOR rather than NDBs or outer markers. Timing an approach from an intersection can be less precise than from a beacon, depending upon the accuracy of your number-two nav.

Where is the missed approach point on the back course?

Since the localizer system you're using for the back course is located near the runway threshold, as opposed to the departure end, the missed approach point is farther away from the runway.

What does the back course button do?

The " BC " mode lets you fly a Localizer Back Course. Since a localizer is only aligned for one specific heading, to approach it from the wrong way(as you have to do on a Localizer Back Course Instrument Approach Procedure) requires you to think backwards and deal with the 'reverse sensing'.

What does back course mean?

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.

What is the approach hold switch?

The APR switch allows you to fly an approach to an airport with an ILS automatically. What you do is enter the ILS frequency of the runway you are landing at. Then fly the entry per the instructions from ATC (or just enter approximately 2000' AGL at about a 15 degree angle) and press the ATC switch so it is engaged.

Do all localizers have a back course?

Every localizer transmitter radiates a signal in two directions, one being the "front course" and the other is the "back course." For example, an ILS RWY 26 with a centerline heading of 260, the antenna is located at the RWY 8 end of the runway and radiates a front course in the direction of 080 for runway 26.

How do you use the back course approach?

According to the AIM, "when flying inbound on the back course it is necessary to steer the aircraft in the direction opposite the needle deflection when making corrections from off-course to on-course. This 'flying away from the needle' is also required when flying outbound on the front course of the localizer."

What is FLC in aviation?

"Flight Level Change" Mode, or "Speed" Mode, adjusts aircraft pitch to maintain a constant indicated airspeed. When you engage FLC during a climb or descent, the autopilot will hold the aircraft in the climb or descent at the airspeed you've selected.

What is approach hold?

Approach hold basically does what it states - it hold the ILS glideslope and runway heading through the entire approach. Do not confuse this with autoland though, as that is not what it does. You must disengage the autopilot shortly before landing, and flare the aircraft manually.

What is approach mode?

Aircraft may be fitted with the Approach (APPR) mode which allows the autopilot to intercept an ILS and perform an automatic landing if it is kept engaged until touchdown.

Why is localizer more sensitive on back course?

​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.

Can you get reverse sensing with an HSI?

Reverse sensing occurs on the back course using standard VOR equipment. With a horizontal situation indicator (HSI) system, reverse sensing is eliminated if it is set appropriately to the front course.

Back course hold switch??

Hello everybody! Can somebody detailed tell me what are the uses of the "Back Course Hold Mode". Is it very important for an autoland?

RE: Back course hold switch??

Some runways have an ILS on one end, but instead of having a seperate ILS on the other end, they have what is called a "localizer Back-course." This is basically the same beam, so if rw 9 has an ILS, rw 27 for example could have the same Localizer beam as the one used on runway 9, except it would appear to be reversed.

RE: Back course hold switch??

Hi Brandon, thank you very much for your useful information. So in what condition that I should use back-course in the FS. Thanks again for your kindly reply.

RE: Back course hold switch??

I've always found this to be one of the most interesting - taking off from KASE at Aspen Colorado, you use the backcourse from the ILS Localizer to fly the DEPARTURE.

When flying inbound on the back course, is it necessary to steer the aircraft in the direction opposite the needle def

According to the AIM, "when flying inbound on the back course it is necessary to steer the aircraft in the direction opposite the needle deflection when making corrections from off-course to on-course. This 'flying away from the needle' is also required when flying outbound on the front course of the localizer.".

Can you reverse sensing a localizer?

As long as you tune the front course for the localizer, you won't get reverse sensing. When configured properly, you can fly the LOC BC approach with normal sensing, and fly "to the needle" like you do in all other navigation.

What on earth are they for? I can't find anything on them, and I would like to know what they do. Thanks.

Guest

alright, thanks for all your help, this will help a lot when the weather is bad or there is very low visibility, i used to manually land using the gps zoomed in to about 2 miles, but this makes things a whole lots easier, thanks a lot

Guest Joshieca

Does FS2k2 auto tune the NAV radios or do you have set those manually? [br] [br] [div align=center] [br] [link:members.cox.net/fstimes/wetimage.html]Weather Image of the Day!

Guest GabrielR

YOu have to do it manually, only the Comm can be tunned via the Auto tune feature.

Guest

Actually FSNav WILL tune the Nav radio for you if you are letting FSNav fly the plane for you. Of course, I don't understand why people even bother to get into a plane and not fly it at all??? I'd rather be a passenger on a real aircraft, and fly my plane in Flight Simulator ;-)

Are the VORs etc. stored on the FS2002 disks anywhere to check up on? I have a few books I have to thumb through which is more inefficent than if they were stored on the disk.Thanks,Robbie

I think when it comes to flight simulation, "Whatever works best for you..." is the rule to follow.For me, the airplane is mine below 10,000' unless the weather is too godawful for hand flying. That gives me a lot of time to tune radios, make sure the airplane's doing what I want it to do, and line myself up.

Do controllers have circle to land clearance?

There aren’t many of those procedures in use, and even when they’re available, controllers are more likely to issue a circle-to-land clearance on the standard localizer/ILS. Still, they’re a nuisance we’re sometimes forced to deal with.

Is it hard to get a back course exam?

The better news is that it ’s equally difficult for an examiner to gain access to a real, live back-course approach (unless they’re willing to conduct his examination at 6 a.m.), so most of the time, you shouldn’t have to worry about demonstrating your proficiency.
