The main runway is on a heading of <a href="http://naco.faa.gov/d-tpp/0911/00430RRY29R.PDF" rel="nofollow">123/303</a> designated 11L/29R. That's a little bit off, but I guess they haven't got around to renumbering it to 12L/30R yet. There is also a shorter parallel runway designated 11R/29L, and a 03/21 on a heading of 033/213.<br /><br />In Tuscon the magnetic variation is 12 degrees, meaning that 135 true is 123 magnetic. So the runway you think of "on a heading of 135/315" is really runway 11L/29R.Aviatrixhttps://www.blogger.com/profile/13634111275860140084noreply@blogger.comtag:blogger.com,1999:blog-10000144.post-64763194973650188232009-10-31T00:08:20.687+00:002009-10-31T00:08:20.687+00:00In Tucson why is the main runway which lies on a h...In Tucson why is the main runway which lies on a heading of 135/315 called 110/290?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1156993569801761582006-08-31T03:06:00.000+00:002006-08-31T03:06:00.000+00:00I've noticed a lot of hits on my blog searching fo...I've noticed a lot of hits on my blog searching for "runway numbers" since the accident. Have a look at the FL390 and FL250 blogs in my sidebar for some discussion.<BR/><BR/>While I understand that a "short runway" warning might seem to make sense to a non-pilot, the truth is that the presence of the sign would pose more danger than it would avert. <BR/><BR/>Airplanes vary so much. A 3500' runway is just great for my operations. It is the pilot's job to know how much runway is required for the weight of the airplane, the temperature, the elevation and so on.Aviatrixhttps://www.blogger.com/profile/13634111275860140084noreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1156991330643450742006-08-31T02:28:00.000+00:002006-08-31T02:28:00.000+00:00Speaking of runway confusion, what did you think o...Speaking of runway confusion, what did you think of the mixup at Lexington, KY airport, when the pilots of a Comair took off from the wrong runway (a shorter one), which then crashed upon takeoff, killing 49 aboard? They were supposed to take 22 and they ended up on 26. I realize this is magnetic headings, but to a non-pilot, the numbers 22 and 26 to me could get easily mixed up, especially if one were tired, having arrived at the airport at 5 am. Why can't airports put warning or caution signs next to certain runway signs, such as "CAUTION, SHORT RUNWAY". Wouldn't that help?Mariehttps://www.blogger.com/profile/15327808913010768783noreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1121056167633699342005-07-11T04:29:00.000+00:002005-07-11T04:29:00.000+00:00Atlanta (Hartsfield) is one of those airports with...Atlanta (Hartsfield) is one of those airports with lots of parallel runways. There are presently four, all oriented 092 - 272. The northern pair are 8/26 L/R, and the southern pair are 9/27 L/R. They're currently constructing a fifth runway, south of and parallel to the other four. My friends and I are taking bets as to what its numbers will be. I'm thinking it'll be 10/28.Scott Johnsonhttps://www.blogger.com/profile/18076313660049246875noreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1120970551715459142005-07-10T04:42:00.000+00:002005-07-10T04:42:00.000+00:00Sorry to come back to this conversation late, yest...Sorry to come back to this conversation late, yesterday/today was moving day. Anyway, runway "17" would be 170º. The rule on the runway designations is that no runway begins with a "0". Runways are always cardinal headings, i.e. 1, 2, 3....9, 10, 11, etc. and are designated by the nearest cardinal heading to their actual heading. Runway 18, for instance might be 185º, whereas runway 19 might be 187º or 193º and so on. I'm fairly certain that when the magnetic heading changes the runway has to be redesignated (whether or not the city council wants to come up with the money), but I could be wrong. Anyway, I sure most of you know all this info, I was just teasing a little in the first comment. And, yes, ATC says, "fly heading zero seven zero".Old Blind Doghttps://www.blogger.com/profile/08534693955145315315noreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1120911451137364032005-07-09T12:17:00.000+00:002005-07-09T12:17:00.000+00:00Frankfurt (EDDF) has a stacked ILS so that two run...Frankfurt (EDDF) has a stacked ILS so that two runways become three. 25R, 25L and (IIRC 26...too lazy to look up the chart). 25L actually has two ILS glideslopes, one that leads to the threshold of 25L and another that leads to a point about 1/3 to halfway down the runway. This "runway" is marked as 26 in the directory. <BR/><BR/>The logic of this is that 25L and 25R are too close together to permit parallel landing operations so, for aircraft that don't need 12000 feet of asphalt, there is a second glideslope that is high enough to permit parallel ops.dibabearhttps://www.blogger.com/profile/05160261542703053377noreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1120837453652713112005-07-08T15:44:00.000+00:002005-07-08T15:44:00.000+00:00Can't say I've ever checked.

You get used to the pairs of numbers that denote runway ends though, there are only eighteen possibilities, and once you know airports with them all there's no more thinking involved. Some of them roll off the tongue easier tha others, though.<BR/><BR/>01-19, 02-20, 03-21, 04-22, 05-23, 06-24, 07-25, 08-26, 09-27, 10-28, 11-29, 12-30, 13-31, 14-32, 15-33,<BR/>16-34, 17-35, 18-36<BR/><BR/>There's another trick, too. Take the two-digits of the number from one end of the runway and subtract 2 from one digit while adding 2 to the other. Now you have the opposite runway. It doesn't work if both digits are less than 2: then you add 18.Aviatrixhttps://www.blogger.com/profile/13634111275860140084noreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1120817457191004202005-07-08T10:10:00.000+00:002005-07-08T10:10:00.000+00:00I suppose until you are used to it, the checking o...I suppose until you are used to it, the checking of the bearing by seeing if the two numbers are 180 apart, is a trifle cumbersome.<BR/>As far as Americans and their spelling, blame Webster and his dictionary.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-10000144.post-1120792816368024532005-07-08T03:20:00.000+00:002005-07-08T03:20:00.000+00:00Centre, center; RWY 07, Rwy 7; Heading, Heafing .....Centre, center; RWY 07, Rwy 7; Heading, Heafing ...
