[Scan-DC] Washington Area Airport Freqs--Final (I hope)

[Steve Thompson]

This will be, I hope, the last update to Washington Area airport 
frequencies.  It now adds data from the FAA's "Airport/Facility Directory" 
published only two weeks ago and therefore about as current as 
possible.   It does not include UHF freqs except for ADW.  I've added this 
data to the Standard Terminal Arrival Charts sent previously and derived 
from is the latest edition of "U.S. Terminal Procedures, Northeast," which 
is the FAA's bible on approach, departure, tower and ground frequencies and 
patterns.  (FAA Product ID BTPPNE from www.naco.faa.gov ).

I have left out the ATIS, Ground Control and other, specialized channels 
which are of minimal interest and which don't change often.  Comments based 
on actual monitoring are welcome.

Reminder that this listing groups frequencies by airport.  If you prefer to 
group them by what the FAA calls a "facility," then lift out all of the 
Approach and Departure freqs and call them "Potomac Tracon," since the 
controllers you'll hear on these frequencies are at that facility in Vint 
Hill, Virginia, near Warrenton.  The actual transmitters are remoted to a 
number of locations around the area.  (See comment below on this grouping, 
though.)

Remember that Potomac Tracon has a few other frequencies, further away from 
Washington, used to handle flights into Richmond and other airports.  Feel 
free to comment and add these frequencies if you monitor them.   Again, 
pardon the fact that the formatting goes haywire when I send this as 
e-mail.  Dump the contents into a word processing program and straighten it 
out.



BALTIMORE-WASHINGTON INTERNATIONAL

Tower					119.4		257.8
Final Approach (from all directions)	119.7		290.475
Standard Arrivals from South		128.35		270.275
Standard Arrivals from West		123.825		254.25
Approach Control from Northeast	119.0
Approach Control from ESE		124.55
Approach Control from SSE		119.7
Approach Control from West		128.7
Additional Approach Control		126.75
Departure Control			126.75

Discussion on Scan-DC earlier this month among list members near BWI has 
frequencies 128.7 and 124.55 coming from transmitters located at BWI.


WASHINGTON DULLES:

Tower for 1R/19L                                  20.1             	338.25
Tower for 1C/19C                                 120.25   	348.6
Tower for 1L/19R & 12/30                  	128.425 	348.6
Approach Control from West  		120.45   	343.775
Approach Control from 
South              	124.65
Approach Control from North              	125.8
Approach Control from North *   	126.1            	338.25
Departure Control to South             	126.65   	350.2
Departure Control to North             	125.05   	350.2

Notes:  * The published Standard Terminal Arrivals to Dulles from the north 
use these two frequencies.

My own monitoring makes me think that Dulles is not simulcasting its UHF 
frequencies all of the time but is using them when necessary.  I plan to 
check this further, but you need to be near the transmitters to hear the 
UHF in many cases.  Comments welcome.


REAGAN NATIONAL:

Tower                                       	119.1             	257.6
Helicopters                                	134.35
Approach Control from South              	119.85   	323.3 and 322.3 *
Approach Control from West              	124.7             	338.2
Approach Control from East		
Standard Arrivals from East               	124.55   	317.425
Standard Arrivals from North              	128.7             	307.9
Standard Arrivals from West               	118.675  	343.7
Departure Control to West (Low)	118.95		257.2
Departure Control to West (High)	121.05
Departure Control to East (Low)		125.65
Departure Control to East (High)	126.55

Notes:  *  If these two UHF frequencies are actually one and there's a typo 
involved, it's in the book that way.  MilAir listeners, please comment.

On those Departure Control freqs for DCA:  The "Low" is the initial 
departure frequency and takes the aircraft up to 10,000 feet, at which 
point the "High" controller takes over and supervises the flight until 
handing it off to Washington Center.




ANDREWS AFB:

Tower                                       	118.4             	349.0
ILS, NDB & TACAN Approaches           119.3              	355.5
RNAV and GPS Approaches          	124.0             	269.0
Other Approaches from South              	128.35   	270.275
Departure Control to N & S               	125.65   	391.1 or 348.725 (the 
two FAA publications differ on the UHF freq)
Departure Control to West                	118.95   	257.2
Andrews Command Post		141.55		378.1
Weather						344.6
AF/USN Reserve Ops			143.8		351.2			

Hope this list is helpful.  If you're hearing frequencies that I've missed 
(other than ATIS, Ground Control, etc.) please let me know by posting to 
SCAN-DC.  I'll post revisions as necessary.

Compiling this list makes me think I should reconfigure my Pro-106 to make 
a scan list for each airport, so that the Approach and Departure Control 
freqs will be grouped with the appropriate airport.  Right now, I have one 
scan list for Towers (handy when meeting people at the airport) and another 
for Potomac Tracon.  But that means all of the Potomac Freqs are a jumble 
and it's hard to tell which airport they're serving.  Luckily, with the 
object oriented programming of the Pro-106, that change is extremely easy 
to do.
