Jet departing Courchevel

So on departure the pilot seems to fly under the overcast layer. It doesn't seem like he climbs out through the layer. What is up with that?

At least there isn't much terrain around.

Seriously. Wonder if the person flying that is familiar with v1. What's the max runway slope for a citation?

Citation Bravo:"Gradient correction factors can be applied to gradients less than or equal to 2 percent downhill or 2 percent uphill."

I don't see a max slope limitation anywhere, but there is no useable takeoff data for greater than 2%. Courcheval is listed (Wiki) at a nominal 18.5%.

So, test pilot.

I'm guessing maybe because he actually doesn't have enough airspeed to climb.

It is straight wing. Unless that airplane is loaded heavy with full fuel it wouldn't matter. The citation 550 variant be it a 560 or Excel or Bravo or whatever is the same wing. It can get pretty slow and still climb. It is a Pilatus wing with poopyer flaps. A citation 650 or 750 oh hell no don't even think of getting slow in normal ops. Aside from the engine failure until about 30 seconds after take off, I'm a lot more concerned those guys ducked under some clouds on the way to the next near smoking hole in the ground.

And I don't mean to disregard the whole V1 thing and the whole planning surviving an engine failure on take off idea. It is a good sound practice to imagine living through every take off if an engine takes a dump. However, I feel like the most stupider part of the video was not climbing and remaining in VFR conditions despite the presence of the obstacle known as the Alps.

Lame. We take off without accelerate-stop distance daily. So do TONS of people, including from your company. 7% grade, yup. No pavement either. Though it's not at 15 billion MSL like this airport.

People need to remember that not everyone operates under 121 or with transport category airplanes.

Where did they "duck some clouds"? I never saw it in the video, and given the weather present in the video, never saw where they'd need to.
