RASS and Ohio Airports
by Tom Lusch
(updated 2002-11-11)

Are you curious if your airport is affected?

[If you came across this page without understanding the context of this discussion, please review the discussion and the many links on the page entitled "I'd rather RAAS."]

The best way to check if your airport is affected is to look at the latest Instrument Approach Procedure Chart for your airport. I have reviewed all of Ohio's, and created the following list. The airports are listed alphabetical by city, along with the airport's approved altimeter settings.

I found that there are 312 Instrument Approach Procedures that support 110 Ohio airports. That is something for Ohio to be very proud.

However, it is disappointing that over half (58) are not backed up with a full-time, immediately & easily available altimeter setting. Should an AWOS or ASOS fail, all the approach procedures that are based on that altimeter setting which is no longer available, immediately become NOT AUTHORIZED. For instance, should the FDY ASOS fail, it affects instrument approach procedures into 9 Ohio airports (16G, 17G, 56D, 5G7, 7I7, FDY, FZI, I95, & OWX)! That's 19 instrument approach procedures affected by the failure of a single ASOS!

My rankings are determined by the availability of the altimeter setting [i.e. Is it backed up by another altimeter setting instrument like a DASI (a Digital Altimeter Setting Indicator, which is found at Air Traffic Control Towers)? Is it available full-time? Is it easily available to the pilot via the Air Traffic Controller that will issue the approach clearance?]

The goal of Columbus Flight Watch, Inc. is to get all Ohio airports at rankings of 1.

Rankings...
   1 = Best (At least one altimeter setting redundant, full-time, easily available) = 52
   2 = Marginal (No backup altimeter setting for periods when ATC Tower is closed)  = 15
   3 = Worst (No backup altimeter setting. Unattended, stand-alone, AWOS or ASOS)   = 43
Altimeter Setting Legend
LCL = Local altimeter
  # = Redundant (i.e. DASI or other approved altimeter exists), full-time, & immediately available.
  ^ = Redundant altimeter setting available, but only part-time.

Note: Approved altimeter setting data based on United States Government Flight Information Publication "U.S. Terminal Procedures, East Central (EC) Vol 2 of 3, Effective 0901Z 3 Oct 2002 thru 0901Z 28 Nov 2002."
