Which reminds me, I wonder how accurate a Portal Hound's "compass bearing" feeling is. Obviously it's good enough to home in on the portal, but is it good enough to use lateral displacement and triangulation to get a rough estimate of distance? If it's accurate to within 1 degree then a 20 mile displacement is enough to tell you whether its approx range if it's within 1000 miles. Angular_____|__distance__|__required displacement resolution__|__(miles)___|__(miles) ____1°______|___250______|____4.2 ____2°______|___250______|____8.9 ____5°______|___250______|___22.0 ____10°_____|___250______|___44.0 ____1°______|___1000_____|___16.8 ____2°______|___1000_____|___35.6 ____5°______|___1000_____|___88.0 ____10°_____|___1000_____|__176.0 ____1°______|___5000_____|___84.0 ____2°______|___5000_____|__178.0 ____5°______|___5000_____|__440.0 ____10°_____|___5000_____|__880.0 ____1°______|___10000____|__168.0 ____2°______|___10000____|__356.0 ____5°______|___10000____|__880.0 ____10°_____|___10000____|_1760.0 As you can see it as the resolution drops off the necessary lateral displacement to triangulate the portal gets large; up to 17% of the straight line distance just to establish what that distance roughly is before traveling it. And we already know from the text that larger portals make a "bigger" impression; but it's possible that also translates to a 'fuzzier' location; making it harder to get a reliable fix. OTOH once Sharona gets airplanes that are safe enough to risk valuable portal hounds in this type of triangulation might become more practical; a hundred+ mile operational radius isn't a bad fit for 3rd or 4th generation airplanes and a quick out and back from the same field, just to get a directional fix is pretty doable; and takes a lot less operational radius than following the bearing line hoping to see the portal before fuel forces you to turn back. |
