Clean aircraft concept?

I am laughing thinking about the conversation they had before departing. Must have been bored that day, and needed a little excitement.
 
I have never been in that sort of environment, but I have been told that in Alaska the standard is that the wing is clean by 80 Knots or abort. Perhaps someone who has experience in that environment could elaborate.

Who is the one checking the wing at 80 though? Third crew member at an over-wing?

Certainly an interesting video...
 
My thought exactly. Even if you could barely see the wing from up front it would be sketchy cranking your neck around at 100 knots to try to determine if enough snow has blown off to make it airborne. Maybe the FA gets on the phone and lets the CA know the snow is gone.

I'm the wrong guy to ask. I only fly during "field grade weather" now. However, the people who told me about that as somewhat of a commonly accepted procedure were more along the line of 135 operators. So, the answer may be "the only guy in the cockpit".

Or maybe it is like this old joke:

So these people are sitting in an airport....as people often do while waiting for flights and such....and they all see these two guys walk by pilot's uniforms, dark glasses, swinging canes in front of them. They go down the tunnel to one of the planes and everyone in that particular terminal starts to get very anxious. Finally they board and as the passengers pass the door to the cockpit they all try to peek inside. The flight attendants start to make the final preparations for takeoff - checking the overhead compartments, locking down the food carts, giving the air safety briefing - and still, the passengers are nervous. The plane taxis...Lines up on the runway....And the engines gun. The plane is speeding down the straightaway getting faster and faster and faster but it's not lifting off the ground! The passengers are looking out the windows and really starting to freak out and as they see the end of the runway coming they all start to scream and the plane takes off beautifully. Shaken up and swearing never to take this airline again the passengers start to settle down. Meanwhile, in the cockpit, the pilot turns to his co-pilot and says, "One of these days they won't scream and we're going to crash."

WARNING
Takeoff is prohibited when snow, ice, or slush, is adhering to wings, stabilizers, AOA or engine sensor probes, pitot tubes, or may be ingested...

I guarantee that doesn't happen in anything turbine with swept, supercritical wings.

Keep in mind (at least on my AC), we're taught that any ice adhesion (even frost) is BAD. The supercritical wing is especially susceptible to the effects of upper wing contamination (although the fact that we have no leading edge devices makes it worse). It doesn't have to appear like chunks of snow, even frost interrupts the flow sufficiently to degrade the lift on the supercritical wing.

How many seasons did you fly in Alaska?

None, but I have enough time in large transport jets to know that you can't see the wings from the cockpit. :)

I've also flown in the winter in former Soviet republics, so that's gotta count for something (we deiced).

I don't believe that I wrote that you could see the wings from the cockpit or that it was a good idea or anything even loosely related to what seems to be making everyone want to argue about something. What I wrote was that people who have flown in Alaska told me that was somewhat of a common practice.
