  1. Re:Questions: on Computer Error Caused Qantas Jet Mishap · · Score: 1

    Correct me if I'm wrong but don't most modern aircraft have an inertial navigation system and a seperate angle of attack transmitter protruding from the plane? Why no redundancy?

    Well, you're confusing some of the terms. An inertial navigation system is for navigation, e.g. north is that way. The failed computer, an "air data inertial reference unit" is (probably) the computer that collects the measurement data from angle of attack probes, pitot-static tubes, altimeters, and whatever other sensors they have, and calculates useful parameters like angle of attack, airspeed, altitude, etc...

    They have redundancy. They surely have multiple angle of attack probes. They might even have multiple computers to compare the results. They surely try to detect and discard erroneous measurements. But sometimes the wrong things will fail at the wrong time and in the wrong way, and all the data will be junk. Murphy was, in fact, an aerospace engineer.

    The flight control computer needs an angle of attack value. They don't have the option declaring the input suspicious and giving manual control to the pilot. Not on Airbus, anyway.

  12. Coconut Migration on Birds Give a Lesson to Plane Designers · · Score: 3, Funny

    They do make a point about the roll rate, but a Skyhawk is much more useful for migrating coconuts. An African swallow could carry one coconut at most, but they are non-migratory, so it is uncertain what sort of range they would have. European swallows are generally thought to be unable to carry even one coconut, unless two of them carried it together, but that increases the risk of mid-air collisions.

    A Skyhawk, on the other hand, could carry a large number of coconuts. However, unlike with the swallows (where the main issue is not the grip but the weight ratios), the Skyhawk would be limited by the number of coconuts that could be attached. The Skyhawk is an attack aircraft with a payload of close to 10,000 lbs, which would make for a lot of coconuts. But, the only reasonable place to attach large numbers of them without causing aerodynamic interference would be the wing pylons, where the bombs usually go. If they were to fit, these coconut packages could not be much bigger than the bombs. As there are only five hardpoints, I can't imagine there being room for more than about 50 coconuts.

    Still, this is a significant improvement over the swallows, and if you had to choose between the two, the Skyhawk would be a much better choice for migrating coconuts into temperate climes. Of course, something like a C-17 would be even better, but those have an even lower roll rate.

  16. Re:Could be bad for ships and planes on U.S. Satellite Plan Could Knock Out GPS and Radio · · Score: 1

    Many (most? all?) US military aircraft already have inertial navigation that is aided by GPS, i.e. the inertial system does its thing, occasionally receiving updates from GPS to reduce error. For them, GPS is not necessary, but it helps. Even JDAMs, which are often called "GPS-guided" bombs, are guided by INS, with GPS aid (if available).

  19. Re:Better AI: do you really want it? on A Gamer's Manifesto · · Score: 1

    AI in OFP doesn't cheat a lot at all. 300 feet is not very far. In fact, it's very close. 300 meters is a farish engagement range, and it's quite possible to take out an entire AI squad from that range if you engage first, if they're in the open, and, most importantly, if you don't miss. Frankly, if you miss from 100 meters, you deserve to get shot.

    In fact, the AI is blind compared to humans. In the open, you'll notice them before they notice you, and if you're behind concealment, they'll walk right next to you without seeing you. They do detect you when you shoot (unless you're really far), but they are slow to react.

  23. Re:Getting stuck? on Space Elevator Update · · Score: 1

    The reason orbital vehicles have problems with heat when reentering the atmosphere is because they are moving at an orbital velocity (for their orbit) before they enter. If you were to jump out of the space elevator, your initial velocity would be zero, which is quite a bit lower. That doesn't mean you wouldn't have any problems with heat, but certainly not as much as something try to get back from orbit.

  25. Re:my vote is .... on Formula One Racing Just a Matter of Crunching the Numbers · · Score: 1

    The tracks are not too narrow. Monaco is an exception, most tracks are wide enough. One element of track design did contribute to the murder of passing, and that's the addition of chicanes. The simplest and safest passing maneuver can occur at a sharp corner after a very long straight, because it is possible to utilize drafting on the straight, outbraking in the braking zone, and the geometry is favorable if you get on the inside. There are no longer any very long straights. The top cars are near equal, but that has never stopped passing. The problem with heavy reliance on aerodynamics is that the surfaces of the car in the back will not be as effective passing through the air disturbed by the car in front.
