No APU, No Ground Air, No Problem?
 

Anyone here refuse to allow passengers to board until ventilation is established? Packing customers into a aluminum tube without fresh air for 30 minutes seems a little unwise these days.

I wouldn't do it. Somebody was just in the news for that... not only did they load up, they flew a leg with no packs or ventilation.

What kind of airplane is able to do that legally?

Fee for departure. No departure, no fee.

To offset this you need captains who understand what it means to be a captain.

I had this exact situation happen years ago in ORD in the summer. APU INOP and no PC Air available. I refused to board the aircraft. I actually had to pull out our FOM to back up my position.

My solution was add an 1000lbs of extra gas. Start number 2 at the gate, cool the plane off and then board. Cooler heads prevailed and that’s what did, don’t be pressured. Be a CAPTAIN

I had to deplane in DFW once for this couldn’t get the engine started and decided to deplane for the heat. Started number 2 at the gate and didn’t board until it cooled down.

I think there was a story from a couple years ago some ladies kid went unresponsive in the back of a hot RJ.

Any airplane that stays below 10K, easy on certain regional routes. IIRC it was ORD to MKE.

There's probably a supplemental procedure to use ram air for ventilation.

there is. Don’t recommend it honestly, had to do it once when we lost the other pack on a plane that already had one pack inop. The plane gets absurdly hot, even in flight. Luckily no pax onboard as it was a ferry flight due to WX.
