• DCA 15 is closed at night, and other times. By closed in this question I mean: airport management places a gigantic lit/flashing "X" in the landing zone of 15. I'd estimate the big "X" is 8 by 8 feet,...

• I've never had the opportunity to fly into a controlled airport with parallel runways, so I've never actually faced the situation. But, in the interest of being ahead of it, when would it be prudent to switch to ground frequency with this clearance (assume I just landed)? N12345, right on E, cross 27 R, contact ground .9 Should I call ground (or switch frequency, so I no longer hear the tower) before or after crossing 27 R? My by-the-book assumption would be immediately, as there's no "then" or "after crossing" or similar, but somehow that feels wrong. I suppose normally it doesn't

• I'm not a professional pilot, just an enthusiast, so this might seem obvious to others; but I noticed that airports don't use sequential numbering for runways, starting from 1. Liverpool (for example) has runway 9/27; so how are these numbers assigned? Also, what do Left and Right signify?

• Let's say I call up Wx and have the wind direction and I know the runway headings from my charts and the pattern is empty. I can do the math, but it's tedious and slow and even worse when there are multiple runways. This is what I usually do: Runways are 13 and 31 Wind is 253° which rounds to 25 \$25-13=12\$ \$31-25=6\$ I'm going to use Runway 31 Is there a trick to determine best runway quickly without doing the math?

• Many airports have parallel runways but only one runway has a PAPI/VASI. If both runways start at the same point and have similar touch-down points, is it safe to use the parallel runway's lights for the approach and landing?

• What difference to the pilot does it make it say a runway is Concrete or Asphalt? Does it require different information in the flight management system or other calculations?

• Considering that building runways is expensive and that they take up a lot of space, could you land a large commercial airliner on a circular runway, braking as you go around the curves?

• I know there are airports with more than one ATC Tower, though I only know it from my own country (SCHIPHOL - EHAM). This airport has two towers called Tower-Center and Tower-West. Tower-West is built...

• Does an electronic database containing the various civil runways in a given region of the world exists? Maybe even categorized by type (e.g., grass vs asphalt), length, if controlled or not, etc. If it does not exists, what would be the effort related to creating one? As Danny Beckett mentions, OurAirports has such data, but there is a "use at your own risk" disclaimer. May any source be reliable and trustworthy or will I find such disclaimer on all sources?

• I have heard about Simultaneous Offset Instrument Approaches (SOIA), special procedures for runways that are spaced particularly close together. How exactly do they work? What are the requirements for an airport to be eligible for the procedure? What special requirements are there for pilots flying the approach?

• An assumed temperature takeoff intentionally requires a pilot to use more runway than would be normally required. Why would someone want to do that instead of getting off the runway in the minimum di...

• Forgive my total lack of aviation knowledge. I just flew out of SFO and was fascinated by the fact that pairs of planes alternated between departing on 28L + 28R (simultaneously) and arriving on 19L/R. My question is this: What amount of micromanagement from ATC exists to keep taking-off planes on schedule and not running into the landing planes, especially in cases where runways cross? How much information does the tower give to the taxiing planes? Thanks!

• FAR 135.385 requires that at your destination airport your flight planning shows that you could make a full-stop landing "within 60 percent of the effective length" of the runway when flying transport...

• Runway numbers in most of the world are based on the runway's orientation relative to magnetic north. For example a runway with a magnetic heading of 135° to 144° will be numbered 14, and one with a ...

• A popular airport near me (KMYF) has two parallel runways, 28/10 R/L and a crosswind runway, 5/23. Almost always, 28R/L is in use. I'm sure they knew that there was generally a sea breeze in the area, and the wind typically will be right down the runway or within 10-20 degrees of centerline. I'm sure they do prevailing wind study for the area, and my questions are about the study: what are there some specifications for the study? Does the study vary in length depending on location? Is there a standard study that they use, and do they test things like average temperature during the study

• In the United States, if I own land that has an area suitable for landing a small general aviation airplane, can I just create a private runway, or do I have to officially be registered with the FAA o...

• For example, let's say we have an Airbus A330 in front, which has just landed, well past the threshold and looks like it's going to be alright. Next in line to land is a small general aviation aircraf...

• I've now seen several landing strips up close and there are lots of tire tracks from planes' landing wheels. I wonder if it somehow modifies the properties of landing strips to make for poorer landing...

• In companion to the other question asking about wheel tire tracks. Planes come down and stop with a significant amount of force which I would expect to cause either rutting or potholes. Are runways susceptible to ruts and potholes? And do these cause significant issues for landing planes?

• A few times, when flying into SFO, me and my fellow passengers were informed that due to foggy weather one of two parallel runways there is closed, causing delays. So, a few questions: Why can only one runway be used during fog? During an instrument landing, if the instruments are precise enough to land the plane exactly in the middle of one runway, then surely they are precise enough to differentiate between two runways? Is this standard practice in all airports or something specific to SFO? Is there some minimum distance between parallel runways above which it is safe to keep them both
