Way too complicated. If you are flying you would not mess around with so many calculations. Just take your desired and make it +/- 30, 45 or 90 (depending on the distance to the VOR). You didn't mention that in your video. You are using a using a 60° intercept in this exaple. If you are 10 NM away from the station that may be perfect. If you are only 3NM away you will desperatly overshoot. If you are lets say 50 NM away you would pick a 90° intercept. Greetings from Austria!
Hey Michael Thanks for the comment. I agree about the calculations but its actually simple if you get the hang of it and happens within a few seconds. Besides at 27:00 in the video, I have mentioned regarding +/- 45 degree correction, so hopefully that puts us on the same page. :) Cheers!
Planes Over Head I am sorry to disturb,but totally confused, Giving a direct +/- 45 degree correction to the desired radial does not always bring out the correct heading. For eg.. if i am on 180 OB And have to inercept 150 OB Using the formula the heading is 060 But just directly applyin a correction of 45 degree to my desired radial (150) The heading is 105. Could you please explain a little ?
This is the example.. Take off from runway 300 Intercept vor on radial 140 What i will do is i will turn left with a heading of 110 until i intercept because left is the shorter distance But what if the same scenario and i have wind coming from 040/10 If i turn left it is shorter distance but wind will be tailwind and then cross wind that will push me away But if i go right the distance will be longer but i will have a head wind and the wind will then be crosswind to help me intercept the vor In this case what should i choose left or right? and towards what heading should i go

One of the methods I am currently studying in my IFR, which concerns the first part of the video, says that if the difference btw Current and Desired Radials is less than 30 degrees, we should make correction by the actual difference, ie. we are using the same value for the heading change. For second example you gave for O/B 090 and you want to intercept 110 = instead of going right hdg 170 degrees, it would be enough to turn right 130 degrees.
Nice video, I like the style. The 3 factor that you use for correction seems to work OK with small differences, for larger ones, it will not give you a good interception angle. Simple example: I2I on radial 140 intercept 090.
It'll work fine even for the larger ones to be honest provided you're close to the station. If you're really far out then even closer interceptions will not be enough with 3 factor. It's about distance from the station.
it doesnt look like its working when the difference is large btween current radial and the desired radial. For example, current = 090, desired = 135. As your calculation with X3, it gives a interception heading of 270. which means i have to turn 180 degrees from current heading to intercept 135. which is wrong
Just one example where this doesn't apply. (Don't judge me but do correct me if I'm wrong here) You're on 020° O/B, you've to intercept 010° O/B [(10-20) X 3] - 010 (10 X 3) - 10 30 - 10 = 020 So heading again 020°?
hi this is good job but you said we must all correction in desired course i think its not good idea .because if you flight to the station or inbound you mast do the correction on current course .assume you are on course 290 to the station and you want to intercept course 340 .base on your calculation we cant find right heading but if we do correction on current course we fund 240 heading that be right heading to intercept redial
Hi, Let's say you are on a radial of 310 O/B 12 NM and asked to intercept Radial 180 I/B. - You are on radial 060 O/B and asked to intercept Radial 270 I/B. How to perform these exercise? Thank you
Fly cardinal directions. For first one fly South for sometime and then turn East to intercept. Or you can fly directly to the station and then fly outbound. Second one you can fly Westerly then southerly after crossing the station to intercept the radial.
@@poh yea I had the similiar thoughts , in both the cases we need to maintain the same DME distance till intercept, It's like following or commencing the DME ARC. Isn't it ?
In I/B to I/B..... If you are on radial 150 tracking inbound with the crs set to 330 and want to track radial 090 inbound Desired - current) x 3) + desired) Give you a heading to turn 090 270-330 ) x3)+270) How’s does this work now
This shall work the (difference x 3) isn't greater than 90. In this case it was (60x3=180). Hence in this case you'll simply fly north heading and intercept radial 090 inbound. In such cases fly cardinal headings as required.
I have a question and i. Need a quick answer, immediately after took off interception, what if we have wind and the radial is in the reciprocal direction.. how to choose which side to go depending on wind?
Which kind of wind.. it should not affect that much anyway.. always heading into the wind.. turn to the side which will push you towards the radial at all times..
This is the example.. Take off from runway 300 Intercept vor on radial 140 What i will do is i will turn left with a heading of 110 until i intercept because left is the shorter distance But what if the same scenario and i have wind coming from 040/10 If i turn left it is shorter distance but wind will be tailwind and then cross wind that will push me away But if i go right the distance will be longer but i will have a head wind and the wind will then be crosswind to help me intercept the vor In this case what should i choose left or right? and towards what heading should i go
All these additions depend on various factors like distance from VOR, speed of aircraft, current winds etc. So keeping all in mind 30 is fine, you can do 10 too, nobody will ask you why, just that with 10 you may intercept little later.
10-15 deg interception is quite enough immediately aftr take off as d CDI will b alive quick n fast as vor stn ws close to d rwy .bt depending on Atc clearance n intercepting radial close to sector flying then 30 deg is also good.after all gud job 👍
So difference between these both is more than 30. So you'll fly box pattern i.e., use cardinal headings. You'll fly east heading to intercept the radial.
This is all great but when atc comes on and tells you to intercept a particular radial out of nowhere because whatever reason, yiu have about 5 seconds to calculate and execute YOU DON'T HAVE TIME FOR ALL THIS MATH CRAP ... HOW ABOUT AN EASY WAY TO DO THIS FAST?
1) Relax with language on the channel. Math maybe crap for you. 2) This method is for freshers pursuing CPL to first break the code to understand fundamentals of radial interception. 3) With practice and more flying experience you'll be able to get better and faster at the same method within 5 seconds. 4) Don't try to use the lift, use staircase for success. It comes step at a time.
