Wally Posted March 15, 2008 Posted March 15, 2008 Can anyone explain the relationship of the runway markers with compass headings? Not certain exactly what you're asking (Runways are at airports, and airports are for airplanes.), but ignorance is no impediment to my speaking...Add a zero to the name and you have the magnetic heading at one time (this changes), rounded to the nearest 10 degrees, ie "RWY 34" would align closest to 340 degrees magnetic.

I undestand the 'adding a zero and getting the degree"... what I want to make sure is that if the reference use runway 10 is given... that I know that I am sitting close to the number and running down the runway towards the heading of approx 100...example: RWY10--------------> (I am headed away from the painted number and going towards magnetic heading)not RWY10<-------------- (I am headed towards the painted number) I do get that AC use the runways and we 9copters" do not, but during preflight etc the terms are used when preparing for flight..we are usually parallel to the runway being used..and we end up in the practice area... right hand traffic vs standard for the AC. Am I close? Quote
captkirkyota Posted March 15, 2008 Posted March 15, 2008 RWY10--------------> (I am headed away from the painted number and going towards magnetic heading) CorrectThink of them as if you were in a fixed wing, when you land or take off you are either landing on the side the number is painted, or starting from it. (filler words to get html to keep runway out here) _____________________________________________ (flying coming in for landing) -----------------------> 10 ----touchdown----->------------>------------->--- (filler words to get html to keep runway out here) _____________________________________________ _______________________________________________________________________________ 10 (Start taking off)---->---------------->-------------------->---------->---------- lift off ------->_______________________________________________________________________________ Quote
ADRidge Posted March 15, 2008 Posted March 15, 2008 Yota covered it well. The only thing I can add is that the numbers are checked every ten years. Just a tidbit to remember for your oral. Quote

shakejke Posted March 15, 2008 Posted March 15, 2008 thanks everyone...helped me out alot You can also figure out what the other runway heading would be if you know just one of the runway numbers. Example If you were landing on runway 12 and you wanted to know what the other end would say, you would just add 1+2 and you would get 3. The other end of the runway would be 30. Just look at a compass and you will see what I'm saying. I don't know if this helps or not, it works for me. Quote

Just look at a compass and you will see what I'm saying. I don't know if this helps or not, it works for me. So if I am approching runway 13 then I add them and get 4, so the number on the other end is 40?runway 15, 1+5=6 so runway 60? You ever heard of reciprocals? the other end of the runway is always + or - 180 degrees! Quote
Gomer Pylot Posted March 16, 2008 Posted March 16, 2008 For runway numbers, just add 18, and if the resut is > 36, then subtract 36 from the result. Quote
captkirkyota Posted March 16, 2008 Posted March 16, 2008 My assistant Chief CFI told gave me an easy way that requires less math. Just move the 2. IE 120 move the 2 over to the 100 spot and it is now 300. 265 move the 2 from the 100 spot to the 10's place 085. 185 take 2 from the 8 in the 10's and add it to the 100 and now it is 365 which immediately you know that it is really 005 since it zero's after 360. 357 move the 2 from the 100's and it becomes 177 and so on.Anyway, I have never had a strong way with numbers as long as I can remember, and this works quite well for me.

Eric Hunt Posted March 16, 2008 Posted March 16, 2008 Add 200, subtract 20. So for 09, ad 200 for 290, subtract 20 for 270. Otherwise, subtract 200, add 20. Quote
betr_thn_Icarus Posted March 16, 2008 Posted March 16, 2008 I do it the same way as "erichunt" because it is easier for me to add or subtract 200 then do the opposite with the 20....instead of using 180 it just makes it easier. Quote

Just look at a compass and you will see what I'm saying. I don't know if this helps or not, it works for me. What you're referring to is that when you add the numbers together for each runway heading the sum is the same. ie 16 and 34. 1+6=7 and 3+4=7. However, as Mikemv mentioned the runway numbers are the reciprocals of each other. 180 degrees apart. Quote

Someone printed a bunch of numbers on it, and by some twist of fate, they go up to 360 and then start over again! Edited March 16, 2008 by palmfish Quote

Mostly due to his avitar....but his tip has some merit on its own ! Really though, all the other methods require too much brain HP while you are approaching a new airport and trying to figure out which way the active is, how should I approach, where am I ..damn look out for that Cessna !! If you cant add 200 subtract 20, you really need to find another hobby.! Goldy Quote

If you cant add 200 subtract 20, you really need to find another hobby.! Goldy That's basically the method I now use, without adding 200 and subtracting 20, I just add or subtract 2 from the middle number and then give 2 or remove 2 from the 100's column. 360 take 2 from the 3 and move/give/add it to the 6 = 180 and vice versa. Just one less step is all. Quote
