Extremely hot temperature in the cabin. Transavia Boeing 737 declares PAN-PAN at Porto. Real ATC

[@SimonLant]

Precise, on point, no unnecessary back and forth. Pilot clear on what he wanted. Get the plane down, simple.

[@Ztbmrc1]

Does anyone know what caused the high temperatures onboard?

[@jednick]

Well, open a window, for Pete's sake.

[@captkev737]

Text book by crew & ATC, well done.

[@DeweyCheatumNHoweLLC]

ATC repeating questions, example "Confirm Pan" Pan after it was called early on.

[@tristated9310]

This is definitely a strange one to me. Anymore info?

[@YouCanSeeATC]

Unfortunately i don't have more info. I was waiting about a month. Probably something with bleed system.

[@SpikePapp]

@@YouCanSeeATC If I had to take a guess, it's probably a failure with the A/C Packs.

Some similar incidents with other aircraft: AA-226 on Mar 30th 2011 - defective cabin temperature controller WF-193 on Sep 11th 2013 - "malfunction of the air conditioning system" XM-2151/JL-2151 on Jun 16th 2014 - "one of the air conditioning systems failed" KC-907 on 16th 2015 - "temperature control of the air conditioning system failed" EV-5009/DL-5009 on Dec 23rd 2015 - "malfunctioning air conditioning system" AC-115 on Sep 17th 2019 - dispatched with pack #2 INOP, unable to control temperature

[@tristated9310]

@TheLoneWolfling Thanks for the other incidents listed that report possible causes. I guess the interesting part to me is, if the plane is so hot 1 minute after take off, why was it not noticed on the ground.

[@TheLoneWolfling]

@@tristated9310 It's normal for planes to run hot on the ground (APU off or struggling, or APU bleed air used to start the engines, or AC off for takeoff). If you get in the air, turn AC on, and things keep getting hotter... that's when you notice problems.

no souls and fuel question. interesting

[@theChickenstones]

Pan Pan Pan is to alert ATC of a non-emergency situation that needs attention. Mayday Mayday is declaring an emergency which requires ATC to ask for Fuel flight time left, Fuel weight for fire response, Souls on board and Infants for evacuation counts and rescue and HAZMAT for specialist ground crews along with landing as soon as possible at the closest available facility.
