ADF Required
When an approach specifies ADF REQUIRED (as in Rochester, NY KROC ILS RWY 4
or VOR RWY 4) is there any legal way to fly the approach without an ADF? It appears to me that the only reason for the ADF requirement is for the missed approach. Can the approach be flown leagally by requesting alternate missed approach instructions that don't require and ADF? |

During the oral, the DE for my instrument checkride asked me if I could legally fly this approach using a C172 with no ADF. I answered "yes" if the aircraft is equipped with an IFR-certified GPS. That answer was wrong. He told me what you stated above. If you ask ATC for alternate missed approach instructions, you can "legally" fly the approach without an ADF. -- Peter ----== Posted via Newsfeed.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeed.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= 19 East/West-Coast Specialized Servers - Total Privacy via Encryption =--- |

No reson you can't use the GPS to hold at KIRKI when you go missed. |

I just found the reference in the AIM that states that both DME and ADF can be substituted with the GPS. Now that I think of it, I recall the chief CFI at my school mentioned he was going to talk to the DE about GPS substitution, as it appeared the DE did not have his facts entirely correct. Then again, this was about a year ago. -- Peter ----== Posted via Newsfeed.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeed.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= 19 East/West-Coast Specialized Servers - Total Privacy via Encryption =--- |

I think the clarification from the FAA is recent about DME and ADF
substitution. However, note that if this is an ALTERNATE airport, you cannot substitute. AOPA has the link, I can't find it right now. "Peter R." wrote in message ...

I think the clarification from the FAA is recent about DME and ADF substitution. However, note that if this is an ALTERNATE airport, you cannot substitute. More precisely, the substitution cannot be considered when choosing it as an alternate. No ADF, can't use it as an alternate. Hoever, once in the air, should you actually require an alternate airport, you are not required to use the one in the flight plan, and you may use one notated ADF required by substituting GPS just as if it were your intended airport and approach. Requirements for filing differ from those for using. Jose -- (for Email, make the obvious changes in my address) |

I am not sure how you decided that the ADF is required only for the missed approach. The AVN NDB serves as the IAF and the holding fix. It is required in order to fly the feeder route from FAULT intersection. AVN is also the fix from which the MSA and the 10-NM approach area are determined. Unless I am looking at the wrong approach chart, it seems to me that you need the ADF in order to fly this approach. |
