My last flight through the DAY class C, they let me fly right over the field at 4,500 using FF. I was expecting to be vectored around but, all they did was give me notices of departing traffic. To clarify: I was at 4,500 when I contacted them and they didn't give me an assigned altitude. They just gave the usual "advise of altitude change". -m -- ## Mark T.

DAY is busy enough to warrant Class C airspace and in Class C airspace VFR aircraft must be separated from IFR aircraft. Overflying VFR aircraft are typically assigned an altitude restriction 500' above whatever is used as the initial altitude for IFR departures. |

Mark T. Dame wrote: No, I'm not. I'm simply pointing out that I also have been right over DAY without being assigned an altitude. While it may be "typical" to assign an altitude in such a case, it is by no means unusual not to be (or, as you stated "pretty odd"). I was merely pointing out that I have been in the same situation as the OP: over DAY without having been assigned an altitude. If you are going right over the field altitude is not nearly as important as position. If the runways are east/west and they are departing to the west then tell the VFR aircraft to pass just to the east of the airport and altitude is irrelavant. Of course if they are not very busy at the time then no restriction is the right move. Be that as it may, it is not unusual (nor "odd") to not be assigned an altitude when over flying the airport associated with a class C airspace. Most facilities use the ceiling of their airspace as the initial altitude given to IFR departures. Here at BIL that means you get 12,000 or requested lower altitude. And since 90% of overflight traffic is lower than that it would be stupid to take the overflights that high. |

I was merely pointing out that I have been in the same situation as the OP: over DAY without having been assigned an altitude. If it is typical to assign an altitude in these cases, it is unusual not to be. Which, while may normally result in an assigned altitude for VFR traffic, doesn't have to. Correct. Be that as it may, it is not unusual (nor "odd") to not be assigned an altitude when over flying the airport associated with a class C airspace. Actually it is, and you're contradicting yourself. |

I'm not going to get dragged into a ****ing contest over semantics, but I'm only contradicting myself if you are misreading (either intentionally or unintentionally) what I wrote. While you may think that it's unusual to not be assigned an altitude when under VFR following through class C or over the associated airport, my experience has shown that, while it doesn't happen all the time, it is not strange, odd, unusually, unlikely, bizarre, goofy, or whatever adjective you want to through in. -m -- ## Mark T.

I can assure you I understood what you wrote, perhaps you meant something else.

It IS unusual not to be assigned an altitude restriction in those cases. |
