How do most of you pilots set up a flight plan and what nav-aids do you use.

As Mike Nash said, you don't need any of those things if you stay out of certain kinds of airspace. While I enjoy the sound of "Nash" and am not complaining at all, I would like to point out that you've added an extraneous N. -- Mike Ash Radio Free Earth Broadcasting from our climate-controlled studios deep inside the Moon Oops.

"Bob Nixon" wrote in message ... The only nav-aids he has is a GPS receiver-display and a required UART G force tripped box flying out of now civilian Williams AFB. If he flew closer and or higher toward Phoenix Sky Harbor airport he would be required to also have a transponder so that the Sky Harbor GCA could track his airplane and altitude and he'd have to tune his VHF radio to the GCA when in .. If he is flying out of Williams Gateway, he is under the PHX Mode C veil. |

Perhaps you mean AN/URT beacon set radio, right? As in this: http://www.tpub.com/1ase2/43.htm To me, UART means "Universal Asynchronous Receiver/Transmitter" and was a handy chip to have when one wanted to convert serial bit stream to parallel byte streams and vice versa (as in modems and such.) Sure beat wiring together (and debugging) discrete TTL chips to accomplish the same thing. I must have gotten those acronyms messed up over the years, How about ELT for emergency location transmitter? |

There are ELTs and ELTs... the usual article may have a remote switch, but emits on 121.5 and 243 MHz I watched the fellow in the next hangar testing his g switch: he replaced the battery, then swung the ELT smartly against a tire. At 5 to the hour, naturally... There was a recent alert about stuck g switches, I hear. The later article features 406MHz emissions I hear. I must find out more about them. Brian W |

Also the monitoring Cospass-Sarsat satellites will not find you with a 121.5Mz ELT as they don't monitor it anyymore. You'd better hope for a nearby commercial aircraft that's monitoring 121.5 - it's about your only chance now days. The 406Mz system is also lots more accurate for position determination, and, the beacons must be registered (registration of 121.5Mz devices was never manditory). Hi, User posting as Dave, do you know how to relate emission frequency to the length of a corresponding quarter wave whip? Brian W |

g'day Brian,
Call frequency "f". Speed of light c = 3*10^8 metres/second. Wavelength = c/f in metres. Quarter-wave antenna length then is c/4*f. So, 406 MHz, call it 400 to simplify a bit. Wavelength = 3*10^8/400*10^6 = 3*10^8/4*10^8 = 0.75 metres. Quarter wave a bit under 20 cm, which would be a bit under 8 inches old scale. Cheers ... MikeW. "brian whatcott" wrote in message ...
