A while back, I was with an experienced pilot, IMC, descending to land
at my home airport. The airport is not in an environment where ATC will give vectors to final. As we approached, ATC asked which approach we wanted. He said that he was "going for the visual." The ceilings were right at the Minimum Safe altitude (MSA)--3000. I think ATC said that we could descend to 3000 and report airport in sight. Is this request of "going for the visual" usual? Is it the norm if ceilings are above MSA? -Sami N2057M, Piper Turbo Arrow III |

![]() I don't know about the rest of ye all, but the real world out here is to be vectored as low as the controller can give you, get the airport in sight, and "cancelling IFR". That way the 1000 & 3 does not apply. Jim Roy Smith shared these priceless pearls of wisdom: - -The MSA has little to do with it. The MSA is an emergency altitude with -no regulatory meaning (at least in the US). What's important is that -you've got the weather minimums for a visual approach (1000 & 3) and -that ATC can issue you a clearance to descend low enough that you can -see the airport (or the aircraft you're following).

It's usually the simpliest and quickest way to get to the airport, if the weather conditions allow it. Is it the norm if ceilings are above MSA? The MSA has little to do with it.

Basically, weather needs to be at least 1000/3, and the pilot needs to have the airport or an a/c to follow in sight. AIM 5-4-20. Visual Approach a. A visual approach is conducted on an IFR flight plan and authorizes a pilot to proceed visually and clear of clouds to the airport. The pilot must have either the airport or the preceding identified aircraft in sight. This approach must be authorized and controlled by the appropriate air traffic control facility. Reported weather at the airport must have a ceiling at or above 1,000 feet and visibility 3 miles or greater. ATC may authorize this type approach when it will be operationally beneficial. Visual approaches are an IFR procedure conducted under IFR in visual meteorological conditions. Cloud clearance requirements of 14 CFR Section 91.155 are not applicable, unless required by operation specifications. b. Operating to an Airport Without Weather Reporting Service. ATC will advise the pilot when weather is not available at the destination airport. ATC may initiate a visual approach provided there is a reasonable assurance that weather at the airport is a ceiling at or above 1,000 feet and visibility 3 miles or greater (e.g. area weather reports, PIREPs, etc.). ======================= Ron (EPM) (N5843Q, Mooney M20E) (CP, ASEL, ASES, IA) |

![]() Is it the norm if ceilings are above MSA? The MSA has little to do with it. The MSA is an emergency altitude with no regulatory meaning (at least in the US).

OK. It just happened, in this case, that ATC was able to let us go down to what was coincidentally that MSA for the area. So, my question becomes, at what point do you abort the attempt to go visual and transition to an IFR approach. Say, you have a GPS and ATC cleared you down to 2000 ft AGL and you are 10 miles from the airport. Do you continue at that altitude to the airport until you are right on top of it (controller permitting), notice that you are still not out of the clouds, and then ask for an IFR approach at that point? Just trying to see how the transition from "going for visual" to "err, no can do...need an instrument" happens. Does the controller force the decision at some distance out? -Sami |

If you get as low as the controller can get you and you still can't see the airport. Just say something like, "negative contact, request ILS" and the controller will give you a new clearance for the instrument approach. Say, you have a GPS and ATC cleared you down to 2000 ft AGL and you are 10 miles from the airport. Do you continue at that altitude to the airport until you are right on top of it (controller permitting), notice that you are still not out of the clouds, and then ask for an IFR approach at that point? That sounds like one reasonable way of doing it. Of course, it pays to get whatever weather info is available. If there's an AWOS/ASOS that's reporting 1500 overcast and the controller says he can only get you down to 2000, there's not much point. Just trying to see how the transition from "going for visual" to "err, no can do...need an instrument" happens. Does the controller force the decision at some distance out? It's not the job of the controller to tell you what to do. You make requests and as long as he's able to, he'll issue you clearances. If you're north of the airport and instrument approach is the ILS-36, you've got to go over the top of the airport to get to the appoach. Assuming no conflicting traffic, you could ask the controller to vector you onto downwind for 36 at the MIA to see if you can see the runway. If you do, you can request the visual (or contact) right then and there. If you don't see anything, you just keep going out to the IAF and fly the approach normally. On the other hand, if you're already pretty much lined up for an instrument approach, you really don't gain anything by asking for a visual. |

I think the question was more on the lines of the appropriate communications with ATC when you think there's a visual in your future, but you can't be certain yet. -- David Brooks |

MSA plays no role whatsoever in any altitude assigned by ATC. We don't know or care what the MSA is. If you have to go by the airport to get to where you would start an approach ask ATC to bring you down to the MVA at the airport as you go by. If you see the airport you can get the visual, if you're still in the clouds you're headed for the approach anyways. |

While the 1000/3 applies because you have to have VFR to get a visual the ceiling needs to be higher than that because there are no MVA's that are even as low as 1000 feet. So practically speaking the ceiling needs to be higher than the MVA for that area. |
