Vector altitude for ILS below GS intercept altitude?
Is it common for the approach controller to vector for an ILS at an
altitude below the GS intercept altitude on the IAP? Today is the third time in the last year or so that Victoria terminal vectored me for the ILS into BLI at 2000 feet, instead of 2100. I'm very familiar with the area and I did not bother to question them. The Canadian controllers provide approach service for Bellingham probably from an agreement between FAA and NavCanada. Maybe the rules are somewhat different in Canada, or they just don't have the right information on this approach? See http://204.108.4.16/d-tpp/0604/00045I16.PDF |

See http://204.108.4.16/d-tpp/0604/00045I16.PDF US controllers in US airspace are required to vector aircraft to intercept the localizer at an altitude not above the glideslope or below the minimum glideslope intercept altitude specified on the approach plate. Where control responsibility within Canadian airspace has been formally delegated to the US by Canada, US controllers apply basic FAA procedures with a few exceptions: http://www.faa.gov/atpubs/ATC/Chp12/atc1201.html It may be that what the Canadian controllers are doing is entirely proper for Canada and the parts of the US where control responsibility has been delegated to Canada. |

Hey Steveo, define the word "required" in the context of FAA ATC. Does it appear anywhere near "slam dunk" in your secret dictionary? |

Once you are below the GS they clear you for the approach. Hmmm, I have been slammed dunked, but not the way you describe it. KHKS Brenz is the final approach fix 1900 glide slope intercept Scenario Me doing practice approaches, at 3000 4 miles outside Brenze Approach 43L descend and maintain 2000, cleared for the ILS 16 Hawkins Me 43L descend 2000, cleared ILS 16 Hawkins Now, here I am 4 miles outside Brenz, not only do I have to get the plane slowed down to 90 knots for a "standard" approach, but also descend rather rapidly to intercept the glide slope. This I would call a slam dunk, an approach that requires more then a 500 fpm descent OUTSIDE the final approach fix. Allen |

But at that point you don't care about the GS. Just go down to 2000
feet. I think the original poster was suggesting being cleared for the approach high and past the GS intercept. -Robert |

Bear with me Robert on this one, as I really consider myself a newbie when it comes to IFR! Can you be cleared for the approach INSIDE the final approach fix, which would be the GS intercept point. Wouldn't you have to be cleared for the approach before the final approach fix? If the original poster was approach and above the glide slope intercept altitude, I was always told, that is a no no since you would get a "false glide slope" read? Allen |

Vector altitude for ILS below GS intercept altitude?
The clearance came well outside the approach fix, but at an altitude below the GS intercept altitude on the IAP. It's also below the GS altitude at the marker. The problem with this clearance is there's no way I can verify my altimeter as I cross the marker. Normally on during an ILS approach, we're suppose to check the altitude on the GS as we cross the marker, and make sure it agrees with the GS altitude over the marker printed on the IAP. This is an important crosscheck of the altimeter settings. |

I jump in this thread regarding a "slam dunk" which Robert referred to and questioned his definition of a slam dunk, which to me is not what you are describing above. C my original posting regarding slam dunk and my thoughts of the definition. Allen |
