GPS Approaches
I had a question about GPS approaches. I have never had the option to learn how to shoot a GPS approach and I was wanting to know if the airlines shot many of these approaches and if I should find an aircraft capible of doing one and learn how.

I dont know about all airlines, however i've heard of Horizon using GPS for some approaches in Canada, and the north west. Obviously some of the airports they fly to are quite remote and nestled nicely in between mountain peaks. I also spoke to an old instructor at pinnacle who mentioned the FMC and GPS usage during approaches. Its safe to say when our turn comes around we'll be using primarily GPS for almost every portion of the flight. Some interesting things being done with Naverus, a new company out of seattle that specializes in developing RNP GPS approaches. Take a look at them to understand some GPS capabilities

Just to add to UNDflyboy...They are now coming out with GPS technology which will not only provide horizontal navigation, but vertical as well. So in the near future, there will be ILS-like, GPS approaches. I think its pretty neat, but I will believe it when I see it!

I believe the GPS with vertical navigation is called a WAAS system. Pretty cool stuff. They are trying to get it at the airport I teach out of. We have a LOC but to make it an ILS they would have to knock down a few houses @ the end of the rwy and that would get the neighbors upset. So they want to take the GPS app we have and make it with the vertical navigation or the WAAS system.

Yeah, I was told that my home airport was selected for ths type of approach - to be used in its experimental stages. I could be wrong...but you are right - I think it's pretty sweet. I believe the GNS-480 is all set up for this type of approach.

Most carriers are certified to conduct 6/6/6 takeoffs. That means that on a runway that has centerline lights and markings, they can depart with RVR 600'/600'/600'.
Of course with this sort of departure, you need a takeoff alternate (in the event of emergency) since you cannot return to the departure airport.

Thanks for the information. So there really isn't any way for a 121 to take off 0/0 then right? Here is the reason I ask. I was asked at an interview what the weather mins for t/o in Chattanooga TN would be in a CRJ.
The t/o ALT just has to be within 1 hour on 2 engines right? no other special requirements at time of arrival or anything else?
