Hoover weighs in on the JeJu crash.
I watch his channel regularly. Flying For Money is another good one.

Having much time in the -800, Iâve been mulling over how this disaster couldâve happened. I wasnât there in the heat of the moment when things are asses and elbows, but there are so many questions I have about this.

WTF
You canât manually turn that off, right? Would have to be equipment malfunction?
Maybe you have to keep feeding it quarters.

If I were a Boeing exec, Iâd be a little nervous right now.

The incoming administration will probably see to it that Boeing gets a pass on their piss poor track record of the last several yearsâŚ

Thatâs profoundly weird.
There is supposed to be a hot battery bus to feed the recorders in the event of an electrical failure. I may have to dig into the B-737 Flight Reference Manual for this one.
Wow.

Yep. Existing in the world is going to get a lot more dangerous over the next few years.

I saw some people online saying complete engine failure includes the black box. I thought, well that seems wrong. But I have no idea. Appreciate your input.
No, that wouldnât be the case. As long as the Auto Transfer Relay switch is in the Auto position (itâs normal switch position), any loss of an engine driven generator is automatically picked up by the other engine driven generator. Even if it was a dual engine failure, the APU can be used to pick up the electrical loads of the aircraft, no problem. If they werenât able to get the APU online fast enough and it was a dual engine failure (I donât believe it was dual engine failure like USAir on the Hudson in '09), the batteries can supply some power to the aircraft for essential electrical systems i.e., there is some necessary load shedding due to it being in a battery powered situation. That will get you at least 30 mins of power long enough to hopefully get on the ground.
Again, I wasnât there, I hate to armchair QB this, but Iâm very puzzled why they went around if they were on short final after having that bird-strike. Thatâs a head-scratcher. And, Iâm incredibly puzzled as to the loss of 4 mins of Flight Data and Cockpit Voice Recordings.

Yes, they wonât record without power, but pulling a CB is very tricky to do, trust me. You have to know which panel to go to behind either the Captain for FOâs side (not sure which side itâs on- we have a guide in our Quick Reference Handbook/QRH that shows us where), and which one to pull.
This is all making me have to dig into the FRM now!

From the SWA Boeing 737-700/800 Flight Reference Manual/FRM:
10.5.10 Digital Flight Data Recorder
Revised: 07/01/2020
The Digital Flight Data Recorder (DFDR) provides a permanent record of operational and systems information including time, heading, altitude, airspeed, acceleration, attitude, engine thrust, and flight control surface position.
The recorder is a solid state device and complies with Federal Aviation Administration and European Aviation Safety Agency requirements for data sampling rates and number/type of parameters sampled.
Operational and systems information are automatically recorded whenever the flight recorder is powered.
The DFDR has the following features:
â Continuously records the most recent flight data, saving the most current data for the last 25 hours of operation
â The DFDR is housed in a sealed container located behind an access door in the far aft cabin ceiling
â Corrosion, fire, and impact resistant, survives deep sea pressure to 20,000 ft (6,096 m)
â Locator beacon operable for 30 days/90 days (as installed)
â Receptacle for downloading and copying data for analysis
It makes mention of not recording with loss of power, but again, Iâm certain there is still power to it from a hot battery bus. I may have to ask someone in the training department!
Unfortunately, any electrical schematics I have are basic as well.
I also looked in our Quick Reference Handbook/QRH and the only CB that can be pulled in the cockpit is the Voice Recorder which is not unusual- if there is an event where the CVR is needed, the CB is pulled to stop the continuous voice recording and preserve the audio data.
I had to do it on my first emergency in Dulles in 2005 when I flew in the regionals and we had smoke in the cabin after takeoff.

This crash is a riddle wrapped in a mystery inside an enigma.
