Resolve potential conflicts with all other aircraft, advise an overtaking aircraft of the distance to the preceding aircraft and speed difference, and ensure that weather conditions at the airport are VFR or that the pilot has been informed that weather is not available for the destination airport. Upon pilot request, advise the pilot of the frequency to receive weather information where AWOS/ASOS is available. And you are perhaps surprised that the pilot guidance and ATC guidance are not the same? :-) Not really. I'm certainly not surprised that guidance to pilots in the AIM is not backed up by regulation. But I do think the FAA makes some attempt to keep the AIM, P/CG, and ATC Manual consistent. There will be inevitable timing differences, but I am somewhat surprised by a long-standing difference. I can accept that the FAA has defined in the nonregulatory AIM the regulation for pilots to follow, as strange as that may sound. But I cannot understand why Mr. McNicoll keeps saying 1000/3 is required for ATC, when the ATC manual says VFR, and the only places I can find that 1000/3 exists is in the Pilot manual (AIM) or in a nonapplicable provision of the FAR. |

"Steven P. McNicoll" wrote in message news 91.155(c), which was the specific regulation you referenced, defines a prohibition against VFR operations under certain conditions in any airspace. The question was, "Where does the 1000 come from?" The answer is FAR 91.155(c). That is the answer you gave. Why is it the correct answer? 91.155(c) does not define VFR conditions or permit any operation. It only prohibits certain operations under certain conditions. How does it contribute toward satisfying the rule ATC must follow to ensure that VFR conditions exist before issuing a clearance for a visual approach? For VFR conditions to exist as required by 7110.65 7-4-3(b) in order to clear an aircraft for the IFR operation under discussion, one must be able to operate under VFR, including obeying cloud clearance rules. That is not correct. The only IFR operation subject to VFR cloud clearance requirements is VFR-on-top. That is not correct. On a contact approach, the pilot must remain clear of clouds. However, I did not say that the IFR operation is subject to VFR cloud clearance rules. I said that for VFR conditions to exist, one must be able to operate under VFR, including obeying cloud clearance rules. In other words, VFR conditions are defined in 91.155(a). When the requirements of 91.155(a) are not met, VFR conditions do not exist and a visual approach clearance may not be issued in accordance with the ATC manual. |

The requirements for the issuance of a visual approach clearance are not found in the AIM, they are found in FAA Order 7110.65. The requirement in FAA0 7110.65 is for VFR conditions -- NOT for 1000/3. |

"Stan Prevost" wrote in message ... That is the answer you gave. Why is it the correct answer? Because that's where 1000' comes from. 91.155(c) does not define VFR conditions or permit any operation. It only prohibits certain operations under certain conditions. How does it contribute toward satisfying the rule ATC must follow to ensure that VFR conditions exist before issuing a clearance for a visual approach? The controller must ensure that weather conditions at the airport are VFR prior to issuing a visual approach clearance. If you have a ceiling of less than 1000' in a surface area you do not have VFR conditions and a visual approach is not available. That is not correct. On a contact approach, the pilot must remain clear of clouds. Yes, he must remain clear of clouds, which just happens to be the same as VFR cloud clearance requirements in Class B airspace and Class G airspace during the day. But VFR cloud clearance requirements are greater in Class C, D, and E airspace, and yet the pilot must still remain only clear of clouds on a contact approach. He does not have to follow VFR cloud clearance requirements on a contact approach or a visual approach. However, I did not say that the IFR operation is subject to VFR cloud clearance rules. I said that for VFR conditions to exist, one must be able to operate under VFR, including obeying cloud clearance rules. Yes, you said that. It's not true. In other words, VFR conditions are defined in 91.155(a). When the requirements of 91.155(a) are not met, VFR conditions do not exist and a visual approach clearance may not be issued in accordance with the ATC manual. That's true, but that does not mean that pilots must adhere to VFR cloud clearance requirements on a VFR approach. Whatever gave you the idea they did? What purpose would that serve? |

"Steven P. McNicoll" wrote in message nk.net... Mr. McNicoll never said1000/3 is required for ATC, he said VFR is required. He said: "1000/3 would be needed only at an airport in a surface area." 7110.65, paragraph 7-4-3 "Clearance for Visual Approach" says VFR conditions are required for the clearance, with no reference surface areas. Please explain why 1000/3 is sufficient in surface areas for ATC to issue the clearance. |

Please explain why 1000/3 is sufficient in surface areas for ATC to issue the clearance. Because that's what constitutes VFR minimums in a surface area. The visibility must be at least 3 miles, less than that and you do not have VFR conditions and a visual approach is not available. If there is a ceiling it must be at least 1000 feet, lower than that and you do not have VFR conditions and a visual approach is not available. This is pretty basic stuff, are you a pilot? |
