Squark 7600

[SLF-Flyer]

A Shuttle America flight UA3445 from Denver to Cedar Rapids is on squawk7600. I am surprised that he has gone up to 33,000 ft.

What is the procedure for a 7600 squawk.

Edit 33,000 in place of 36,000

I am please to say that he/she has changed the squawk from 7600 to 1415 at 2115 GMT, so it looks as if the problem has been resolved

What is the procedure for a 7600 squawk.

Depends on the weather. If you are in VMC you land. If you are in IMC:

3. IFR conditions. If the failure occurs in IFR conditions, or if subparagraph 2 (http://www.faa.gov/air_traffic/publications/atpubs/aim/aim0604.html#uWB230ROBE) above cannot be complied with, each pilot must continue the flight according to the following:

(a) Route.

(1) By the route assigned in the last ATC clearance received;

(2) If being radar vectored, by the direct route from the point of radio failure to the fix, route, or airway specified in the vector clearance;

(3) In the absence of an assigned route, by the route that ATC has advised may be expected in a further clearance; or

(4) In the absence of an assigned route or a route that ATC has advised may be expected in a further clearance by the route filed in the flight plan.

(b) Altitude. At the HIGHEST of the following altitudes or flight levels FOR THE ROUTE SEGMENT BEING FLOWN:

(1) The altitude or flight level assigned in the last ATC clearance received;

(2) The minimum altitude (converted, if appropriate, to minimum flight level as prescribed in 14 CFR Section 91.121(c)) for IFR operations; or

(3) The altitude or flight level ATC has advised may be expected in a further clearance.

Not knowing when they had the problem, if the clearance off DEN was to climb to 15,000 and expect FL330 in ten minutes and they lost contact during the departure, after ten minutes you go up.

Thanks MarkerInbound for your comments. The 7600 squawk was transmitted soon after takeoff, luckily it appears that take off was almost straight out.

As a lot of planes now have satellite comms, I did wounder if they may have used it as a backup.

Airlines buy satcom for planes that will operate outside of VHF range. As Shuttle America doesn't normally (if ever) get out of VHF range, I doubt the company would pay for HF or satcom.

American Eagle AA2872 / EGF2872 is on squawk 7600 on a flight from Dallas to Bloomington.

I take it a report will be filed to see if there is a common problem, as both planes were made by Embraer. At least it is not the 787 having these problems, I just hope I have not put a death wish on that plane.

I take it a report will be filed to see if there is a common problem, as both planes were made by Embraer.Two incidents don't constitute a trend. If there are sufficient other similar events also involving Embraers, it's possible that the SDR or ASRS systems might pick it up, but that's not a given.

At least it is not the 787 having these problems, I just hope I have not put a death wish on that plane.:ugh:

Hasn't anyone considered that it might be singer trouble? If I had a pound for every time I'd seen a wrong code set up I'd be a rich man!

[DaveReidUK]

Hasn't anyone considered that it might be singer trouble?Is that ATC jargon ?

Or are you having finger trouble typing finger trouble ? :O

Trouble with the sewing machine? :)
