The intercept angle is only about 20 to 30 degrees. You're right that someone on a head on collision course would close in on a smaller interval of time, but the main point is where to look for other planes that concern you the most. Contrary to what most pilots do - the look all over thing - things that concern you the most appear within a small sector of sky.white_knuckle_flyer wrote: What kind of heading differential was there between the two of you ? With the fisheye effect it looked something like around 60 degrees, give or take. Am I even close ? I suppose the scenarios that would have me sweating the most would be the ones closer to 180 degrees, like someone heading 010 and the other at 170. In that case, they would close in pretty quickly I assume.
Yes, all the crazys will be doing this, the NORDO traffic, ultralights etc. Just fly through the airspace. ATC is less scary than encounters with the rest. That said though, such traffic won't be going "every which way", They'll be going on predictable paths, for the most part.The other scenario is flying <3000, especially underneath a class C or whatever. That's where I would expect you see a lot of traffic going every which way and sandwiched between 500 feet of airspace. Obviously good to avoid these areas altogether, if possible.
Think about it logically, why would someone be there? Its unlikely that they'll be exiting or entering the airspace, they're likely to be following a path skirting the airspace. For the most part, traffic isn't as random as one would think.
