"Movement Area" (airplanes and trucks)
Howdy!
In article . net, Steven P. McNicoll wrote: "Bob Gardner" wrote in message ... "Movement area" is defined in the Pilot/Controller Glossary. At Renton, Washington, the whole airport is non-movement except for the runway and the runup areas. Ground Control will answer if you call, but no calls are expected. Conflicts between airplanes and vehicles are worked out between the participants with no input from the tower cab. FAR 91.129 states "No person may, at any airport with an operating control tower, operate an aircraft on a runway or taxiway, or take off or land an aircraft, unless an appropriate clearance is received from ATC." There is no exception for taxiways designated as nonmovement area. ....and that has bearing how? Are you claiming that the non-movement area is somehow magically placed under 91.129? Pray explain clearly how you arrive at that conclusion, or clearly state that you didn't mean for us to infer that implication. yours, Michael -- Michael and MJ Houghton | Herveus d'Ormonde and Megan O'Donnelly | White Wolf and the Phoenix Bowie, MD, USA | Tablet and Inkle bands, and other stuff | http://www.radix.net/~herveus/wwap/ |

Bob Gardner The airport operator will define what is or isn't a movement area. Some taxiways are movement areas, some aren't. Usually the operator wants the taxiways designated as movement areas so they can pin more blame on the FAA for an incident. |

Given the cited wording, how can that be a nonmovement area? - Andrew |

online.com... Well, this was on *taxiway* H. Given the cited wording, how can that be a nonmovement area? There are "taxiways" and there are "taxiways". What matters is how the airport operator has defined the non-movement areas. You can easily see that from the markings on the pavement, or of course you could ask the controllers or other officials at the airport. Just because a person might use the word "taxiway" to describe an area on the airport, that doesn't mean it's subject to the regulation that was quoted. In this particular case, "taxiway H" does not appear to be charted on the official chart, and of course without seeing the airport myself, I can't comment on how it's labeled or marked. However, looking at the airport diagram it certainly seems plausible that there's an area described as "taxiway H" but which is really just part of the ramp. Regardless, there are examples of places where taxiways (that is, long stretches of pavement on which aircraft are expected to taxi) are simply not part of the movement area, and are not subject to the regulation that was quoted. Renton, WA is one such example (already cited in this thread). If it were true that one could not operate an aircraft on a taxiway that is within a non-movement area without an ATC clearance, then thousands of pilots each day would be in violation of that regulation. I personally don't believe that's the case, so through proof by contradiction, the regulation doesn't apply to taxiways that are within a non-movement area. If someone has some compelling evidence to suggest that these thousands of pilots ARE violating the regulation, and can explain how that could be and yet the FAA doesn't seem interested in citing any of those pilots, that might be an interesting topic. But I doubt such evidence will be forthcoming. Pete |

Are they marked at RNT in such a way as to make a distinction between "the ramp" and "the taxiway"? - Andrew |

"Movement Area" (airplanes and trucks)
"Peter Duniho" wrote in message ... You're pretty funny (read, "idiotic"). Ya think? The areas within the non-movement area are not defined as "runway" or "taxiway", with respect to that regulation. They're not? What are they defined as? What controlled airport has a runway that is designated as nonmovement area? Movement (including operation of an aircraft) without a clearance from ATC happens all the time in non-movement areas at airports all over the country. Correct. It happens that at Renton, they have defined the non-movement area to include all of the airport except the runway. Technically, that means that the pavement one taxis on is not a "taxiway". Oh? Well then what is the pavement that one taxis on in nonmovement area that is not loading ramps or parking areas called? You wishing it to be otherwise doesn't make it so. Agreed. It is the definition of nonmovement area in the Pilot/Controller Glossary that makes it so. NONMOVEMENT AREAS- Taxiways and apron (ramp) areas not under the control of air traffic. |

"Movement Area" (airplanes and trucks)
somewhat related but fun:
i stopped in mexico city en route to Buenos Aires a few weeks back. they required our Mexicana flight from denver to deplane out on a ramp in the boonies, as they learned they couldn't match a bag to a person. we deplaned via stairway, had to stay in a bus for half hour, the (at dusk), after everyone gathered their bags the two busses went careening around jets down the mile long terminal. the roadway next to the taxiway was marked about as well as any other street in mexico, so i had a great time sitting in the front by the driver dodging jets, baggage carts, and other assorted big city airport things i loved it |

"Movement Area" (airplanes and trucks)
"Andrew Gideon" wrote in message online.com... Parallel to and east of P. It extends between N and D. I assume it has signage and markings consistent with other taxiways at CDW. Any idea why taxiway H is not on the airport diagram? It's the parking area near the east side of 9-27. Why is it called RN tiedown? Either H or 4-22, if P is closed anywhere between D and N. One could taxi north on 4-22, left on B to N, thus keeping use of 4-22 to a minimum. Those routes require either taxiing on an active runway or crossing it, use of H requires neither. That's likely why he instructed you to taxi via H to N to RN tie-down. |

gonline.com... Looking at the diagram for RNT, taxiways A and B appear similar in structure to H at CDW. Are they marked at RNT in such a way as to make a distinction between "the ramp" and "the taxiway"? Oddly enough, never actually have I been anywhere off the runway at Renton. So I don't know what the on-ground signage is. However, since the "everything but runway as non-movement area" is relatively new, it wouldn't surprise me to find that the markings are more typical of what one might find in controlled areas of the airport. My point is that the regulation that was quoted, asserting that one cannot operate an aircraft on a taxiway at a controlled airport without an ATC clearance, is clearly not applicable to taxiways within a non-movement area. Clearly, at least with respect to that regulation, those "taxiways" are not defined as "taxiways" for the purpose of that regulation. Even if they are otherwise exactly like a taxiway in every other respect (including being called a "taxiway" by ATC). In your case at KCDW, the important question is whether the boundary of the non-movement area is clearly marked on the pavement. I don't know whether it is or not; I suspect that because ATC treats it as a non-movement area, that it is so marked, but it's possible that it's not. If it's not, you have a fair grievance in this situation. If it is, then you don't. Pete |

Are you claiming that the non-movement area is somehow magically placed under 91.129? Pray explain clearly how you arrive at that conclusion, or clearly state that you didn't mean for us to infer that implication. No, I'm not claiming that the nonmovement area is somehow magically placed under FAR 91.129, I'm pointing out that designating taxiways as nonmovement areas does not remove them from the regulation. FAR 91.129(i) requires a clearance to operate on a taxiway at any airport with an operating control tower. It provides no exception for taxiways designated as nonmovement. |
