IFR use of handheld GPS

"Sam Spade" wrote in message news:nTo6g.175187$bm6.57868@fed1read04... The "rule" is that direct routes initiated by ATC are limited to the service volume of VOR (or rarely, NDBs) and the controller can assure that MIAs will not be violated. When the pilot makes the request, though, let the buyer beware. That's not correct. NAVAID usable distance limits are based on MSL altitudes, service volumes are based on AGL altitudes. It doesn't matter if the routing is initiated by ATC or requested by the pilot, radar monitoring is required when operating outside of the specified altitude and distance limitations in controlled airspace unless approval has been obtained from the Frequency Management and Flight Inspection Offices to exceed them or the requested routing is via an MTR. What did I say that is not correct, and inconsistent with 7110.65 4-1-1? |

What in the following 7110.65 instruction is inconsistant with what I stated? 4-1-1. ALTITUDE AND DISTANCE LIMITATIONS When specifying a route other than an established airway or route, do not exceed the limitations in the table on any portion of the route which lies within controlled airspace. (For altitude and distance limitations, see TBL 4-1-1, TBL 4-1-2, TBL 4-1-3, and TBL 4-1-4.) (For correct application of altitude and distance limitations see FIG 4-1-1 and FIG 4-1-2.) TBL 4-1-1 - VOR/VORTAC/TACAN NAVAIDs Normal Usable Altitudes and Radius Distances Class Altitude Distance (miles) T 12,000 and below 25 L Below 18,000 40 H Below 14,500 40 H 14,500 - 17,999 100 H 18,000 - FL 450 130 H Above FL 450 100 |

Nonetheless, the references both you and I cite are identical. So, you didn't answer my question, except to implicitly admit you are wrong on substance. (ye gads!) |

Nonetheless, the references both you and I cite are identical. I didn't cite a reference, I just answered your questions. So, you didn't answer my question, except to implicitly admit you are wrong on substance. (ye gads!) Actually, I did answer your question, twice. You're just too dim to realize it. You wrote, some time ago now; "The 'rule' is that direct routes initiated by ATC are limited to the service volume of VOR (or rarely, NDBs) and the controller can assure that MIAs will not be violated." The "rule" has nothing to do with service volumes. NAVAID usable distance limits in FAAO 7110.65 are based on MSL altitudes and flight levels, service volumes are based on AGL altitudes. Is the bulb any brighter now? |

Is the bulb any brighter now? No, I need more help to understand how VOR or NDB direct-route assignments by ATC are based on AGL altitudes. |
