Title: Squawking 7700
Post by: RodBearden on September 15, 2008, 05:05:11 PM
Hi guys - I'm a newbie when it comes to Squawking.

I think I read on the forum somewhere that 7700 is used for emergencies and 7600 for radio failure, so I only a few days ago, I set up alerts for these, and I've just seen my first one.

It was Ryanair B738 EI-DLJ squawking 7700, apparently en route from EIKN to EGSS - it descended very rapidly and was landing at EGGP when I lost contact with it at the normal height where I lose contact at EGGP.

Is this a noteworthy event that might appear on the news, or is it a common sort of occurrence?

Squawk 7700 means emergency. I believe they had a cabin depressurization and then did an emergency descent into the nearest field.

Just had 2 in the space of 5 minutes, a BMI1353 seen over the MCT and CFE36L was just timing out when i noticed it, both squawking 7700, not sure of any details regarding both flights.

So either it's a bad day, or it's a pretty common phenomenon, then :-(

I do seem to get a lot of 7700 squawks,but as I understand pilots do sometimes practice this emergancy procedure.

Just picked up a Jet 2 B737 (reg G-CELE, flight id EXS313) on route from Belfast to Barcelona squawking 7700 and landing rather quickly at Toulouse in France.

Indeed the aircraft you picked up is a Channel Express 737-3A,apparantly a regular route for this craft.
