Great tutorial. I'm currently pursuing IFR rating and this is helping.
+Dean Rodriguez You're welcome :)
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!
the +/- 45 thing, is it also applicable for OBto IB and IB to OB??? if yes, then do we just add/sub from the desired course ?
Yes!
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 ?
+/- 45 will not give you same answer! This will just make sure you intercept the radial.
Great Vlog brother. Keep it up. It is working.
God bless you and your family 💯💯💯🧡
Thank you!
Very well explained. Good stuff
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.
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.
You can do that too! It isn't wrong, just that it depends how far you are from the station and the speed of the aircraft.
Amazing explanation
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
Great job sir... It would be so helpful if you could demonstrate the same on G 1000 trainer software
Great video! Thanks
You're welcome
27:00
Can I apply +/-45 degrees to the desired radial anywhere, except for the takeoff one?
Yes you can, that's a good thumb rule!
Great video really helpful
Thank you!
The answer to the last example is 255 deg....and not 245 deg....other than that great video!!really helpful.....keep it coming...
Thanks a lot! Yes missed that, perhaps distracted! Anyway thanks a ton for that correction. Will put it up on the description!
Very nice explanation sir.
Thank you!
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
+taimaz sepahi Different people have different methods to do it, whichever suits you and you understand the best should be followed :)
Wonderful, do you have plotting videos ?
No I don't plotting videos!
Lovely and helpful.
Glad it was helpful!
nice video.really helpful
Glad it was helpful!
Very informative
Could you explain why do we do difference *3? Then for larger difference in angle say a difference of 50 (50*3=150) is that still correct?
Nope at the end of the video I have mentioned, if larger differences what to do, limit the answer to 90 degrees only.
I thought you should multipy the difference you get frm subtracting your DLOP frm PLOP by 2?
Very nice tutorial. Keep up the good work ;)
+Ricardo Santos Thank you! :)
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
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.
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
For differences more than 30 degrees or so, just fly the cardinal headings to the correct side to intercept!
Nice
Plz add video for box method of intercept giving both i/b and o/b examples.
Noted
wow your channel is amazing!!! are you on instagram?? cheers!
Thank you! Yes you can find planesoverhead
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 ?
I mean if we are not going overhead or to the station!
Thanks.
You're welcome
Why we are adding +/-30 immediately after takeoff to intercept 100 we can intercept by adding 10 any way
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.
Yes .. but if we add 30 degrees we have to bank more to reach desired radial.
Depends on the aircraft too
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 👍
How we can find relative bearing ?
Relative Bearing = Magnetic Bearing - Aircraft Heading
Nice explanation thanks, but please don't use the light green pen, it's not clear.
The newer videos don't have the pen paper thing anymore.
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°?
Difference is 10 x 3 = 30
010-30 = 340 is the heading to fly.
@@poh Sorry but it doesn't make any sense
Difference between radials = 10
Multiply that by 3 = 30
Subtract that from desired radial (010)
010-30 = 340 is the heading to fly to intercept 010
Can you solve one interception as m getting wrong answer..OB to OB
Current rdl is 350 and desire is 070
What will be heading to fly ??
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.
Planes Over Head.... m sorry but I still didn’t get exactly what to do as this is not mentioned here...pl elaborate
The radial (070) is to your right. Add 45 deg to it = 115 deg. Turn right onto 115 and 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.
300 - 45 is 255.
It's there in the description. Thanks.
I/B to I/B your calculations are wrong!
Kindly check description!
Not sweet.
?
maybe useful if you have to solve navigation on paper you also fail to explain what's the actual purpose of all of it.
😁 let me know what is the actual purpose
Planes Over Head catch a VOR radial?
That's the name of the video and in the description too.
