Questions on high altitude pressures
"Viperdoc" wrote in message
... Anthony will never admit that he's wrong, nor will he ever accept a point of view offered by others. This is why he is a social outcast and can not find or hold a job. What kind of troll would ever give up? All he wants is someone to agrue with. He's found that here. Too bad he wrecked the place in teh process. |

Questions on high altitude pressures
Dave Doe writes:
What is WAAS or RAIM etc etc - any aviation GPS technology - without GPS itself? WAAS is a navigation technology that relies on GPS. It is not _part_ of GPS. These technologies are little more than GPS enhancements so that aviators can use them to provided required and determined accuracy. RAIM isn't even that much, but WAAS is an augmentation technology. The fact remains that it isn't part of GPS itself. GPS is otherwise useless for aviation - handy for a VFR pilot - but it must not be relied on for either altitude or positional data - it's an aid only. It's very useful for lateral position in many circumstances, even for aviation. The altitude data is too unreliable to be useful for aviation. |

Just an extra, extra point.....there is no FL 120 Of course there is.....maybe not in your part of the world, but I seem to recall transition altitudes as low as 6,000' in some of the places that I have flown. In fact, San Juan's CTA is listed as starting at FL 25. Bob Moore ATP CFI PanAm (retired) |

Dave Doe writes: What is WAAS or RAIM etc etc - any aviation GPS technology - without GPS itself? WAAS is a navigation technology that relies on GPS. It is not _part_ of GPS. Wrong again. WAAS is a subsystem of GPS that transmits localized GPS correction information for the US via a pair of geosynchronous satellites. WAAS merely provides one more signal among the many that make up the GPS system. It's very useful for lateral position in many circumstances, even for aviation. The altitude data is too unreliable to be useful for aviation. Wrong again. With WAAS corrections, the maximum lateral and vertical error is 7.6 m under all cicumstances, makeing it more than reliable enough to make vertically-guided landing approaches in IFR.

No, WAAS is an independent system that relies in part on GPS. There are many such systems (indeed, anyone can set up such a system). Totally and utterly wrong yet again. http://en.wikipedia.org/wiki/Wide_Ar...ntation_System http://www8.garmin.com/aboutGPS/waas.html http://www.faa.gov/about/office_org/...as/howitworks/ Wikipedia says you are wrong. Garmin says you are wrong. The FAA says you are wrong. You are wrong, wrong, wrong. That's three strikes, you are out. -- Jim Pennino Remove .spam.sux to reply. |
