General Discussion / Weekday ATC w/ Me
« on: April 25, 2010, 08:48:37 PM »
If you're looking for some fun afternoon flying, come check out ZDV's airspace. I'm staffing up DEN_CTR each weekday between 2100Z and 2300Z awaiting whatever traffic you feel like bringing. Try the approaches into Aspen, Telluride, or Eagle County, or do a city hop between Denver and Colorado Springs. Or you can check out the border ARTCCs to see who's online, and pick your favorite airline route.

My "official" schedule will be booked into VRoute, so you can confirm there.

General Discussion / NACO No More?

I went to to get some charts, and the Web page itself is renamed: National Aeronautical Navigation Services, AJW-37. The digital charts are still available, but what's the reasoning behind the name change?

The Control Room Floor / New Weight Class for ALL 757s
« on: April 11, 2010, 07:18:19 PM »
James McMannamy pointed this out in the VATSIM Forums, and I figured it would be beneficial as a controller tip in ZDV's forums, and of course, here.

The FAA has released a notice addressing the reclassification of the "heavy" category of aircraft to become aligned with the International Civil Aviation Organization's (ICAO) "heavy" classification.

To be considered heavy under the new policy, aircraft must have a maximum certificated takeoff weight (MTOW) of at least 300,000 lbs. The old rule to be classified as a heavy was an MTOW of 250,000 lbs.

Boeing 757s, both -200 and -300 models, are therefore all classified under the "large" category, and "heavy" will no longer be part of any 757 aircraft callsigns.

Radar controllers:
For the purposes of wake turbulence separation, the 757 (again, both the -200 and -300 series) is a "large" aircraft when it is trailing behind another aircraft. When it is ahead of another aircraft, it is separated as a 757 (not a large nor heavy; the 757 has its own classification). If you don't know what that means, then you probably need to check out 7110.65T Chapter 5-5-4 or this topic.

Radar Wake Turbulence Separation Minima:

B757: UAL757
B737 (a "large" aircraft): SWA300

UAL757 is behind SWA300. (SWA300 is ahead of UAL757.)
Boeing 757 behind a Boeing 737 = 3 miles.
- A Boeing 757 is a large aircraft when it is behind another aircraft.
- Because it is behind the 737, the 757 is considered large.
- Large behind large = 3 miles of separation.

UAL757 is ahead of SWA300. (SWA300 is behind UAL757.)
Boeing 757 ahead a Boeing 737 = 4 miles.
- A 757 creates more wake turbulence than a regular "large" aircraft.
- Because of this, aircraft behind it need more separation than they would need behind a regular large aircraft.
- A large aircraft (the 737) behind any 757 = 4 miles of separation.

FAA Notice:

The Classroom (Controller Tips) / How Are Squawk Codes Assigned?
« on: March 21, 2010, 12:53:23 PM »
How are squawk codes assigned in tower cabs? I understand with the radar systems there is a function to do this (simulated with the F9 key in VRC/ASRC), but how would a clearance delivery controller, for instance, select a squawk code? Are there differences between newer towers and older towers in terms of the systems used to assign the codes?

The Control Room Floor / Range Rings and Radar Sites
« on: February 22, 2010, 05:33:37 AM »
Are the centers of range rings on radar scopes associated with the location of the radar site? And does anyone know where I could see the locations of those sites? I've tried looking around on Google without any results.

General Discussion / Party at the FAA!

Miley should do a remix:
So I put my hands up, they're playin my song, the butterflies fly away...yeah-ah-ah-ah. It's a party in the FAA.

I just happened to read this, and I thought it might be worth it to pass along:

General Discussion / Squawk Codes

Does anyone have a copy of the VATUSA-designated ARTCC squawk codes?

The Control Room Floor / Okay, REALLY?
« on: August 17, 2009, 10:15:40 PM »
This was a misunderstanding as to why JFK inserted a "use the assigned runway" clause in their ATIS recording. Disregard!

I recorded it here. It sounds like a live person is on the other end, too   .
