Just for fun, but I just saw this retarded pilot - Page 1

content: I'm not sure if I was seeing wrong, but it seems like the pilots didn't deploy much flaps and didn't abort taking off after a stall (they should have enough runway left to stop, they were using runway 18, which is a 4km runway, more than the sum of takeoff distance and landing distance of a 737)?

content: Flaps and slats were set, I don't believe that was the issue. My guess is that the rotation was early because someone got the weight wrong or it was just a simple brain fart. A non-event in either case.

content: Bet there were a bunch of excited passengers and flight crew. But stuff like this happens more often than you would like for a variety of reasons. Showing off for someone and unusual wind conditions are a couple more. The planes have a skid plate back there to limit damage when it does. I believe that touching that plate to the ground leads to some mandatory inspections, which in turn doesn't help the pilots standing with his company.

content: Quote from: W9GFO on April 09, 2017, 09:59:57 amThe take-off flap setting on the 737 is 5 degrees; and on the video the flap are seen being down at 5 degrees (visible at about 0:27 in the video).Attempting take-off with the flap up on the 737, turns on a really annoying alarm (a buzzer actually).For the early rotation, it does not look pretty, but I am siding with W9GFO.

content: My last trip to Las Vegas - the return flight was the craziest thing I've ever been on. The crosswind legs of the climb out in particular, it was extremely windy and the way it pushed the plane sideways, and the way the bottom dropped out on the downwind leg - Luckily it all settled down after passing Lake Mead and the rest of the flight was completely smooth.

content: Quote from: blueskull on April 09, 2017, 09:29:12 pmThose flaps are fully deployed.Flaps do not provide lift for free, there is a huge amount of drag penalty when using them, which is great for landing but not so great for takeoff. When taking off you generally use just a small amount of flaps, if at all.

content: Quote from: W9GFO on April 09, 2017, 09:49:10 pmFor the sake of accuracy - that statement was a generalization of all fixed wing aircraft. I don't recall ever being in a commercial airliner that did not use at least a small amount of flaps, but I have taken off many times in GA aircraft with zero flaps.With flaps deployed you get off the ground at a slower speed but your best rate of climb is with the flaps retracted. Your best angle of climb on the other hand will be with some flaps, but rate of climb suffers.

content: Quote from: SkyMaster on April 09, 2017, 05:23:34 pmI remember an aircrash investing about an MD82 that crashed trying to takeoff in the wrong configurationthe alarm didn't sound because there was no power to it, there was no proof if it was intentional or not but apparently some pilots routinely pulled the circuit breaker on the takeoff alarm because it kept sounding when taxing fast

content: As others have said, it depends on the plane as to when to use flaps for take off, and how much.Either someone did a mis-read of airspeed and tried to pull it off the ground early, or like someone said, they had a bad weight.I know the weight issues happens. Checked bags, they have the real weight. Each passenger is given a weight for them and also for their carry on bags. But that is guess, based on the high side and what a person can carry and fat people. They hope it averages out.A friend and SouthWest pilot and I were doing a bit of hangar flying and he told me about a similar issue he had. The plane just didn't want to climb out as expected. Seems most of the people on the plane had just come from a coin convention and had lots of very heavy carry bags with coins. They were much heavier than expected.I also heard from someone years ago coming out of Reno, NV. The elevation os 4,500 feet and the main runway is not that long. The passengers were leaving from a bowling tournament. Nothing crashed or broken, just a scary event for the pilots.

content: Here is an interesting report of a crash in Detroit, 1987. Although the NTSB did not confirm the cause, it was widely rumored that the pilots used a circuit breaker to incorrectly set the flaps prior to TO.https://en.wikipedia.org/wiki/Northwest_Airlines_Flight_255My daughter and I were returning from New Hampshire that day and stopped in Buffalo to avoid the scene.John

content: Quote from: langwadt on April 09, 2017, 10:08:42 pmPulling a circuit breaker to deactivate something or resetting a circuit breaker to reset somethingusedto be done, up to the '90s, maybe. Every SOP (Standard Operating Procedure) that I read prohibit resetting circuit breaker in-flight, and prohibit pulling a circuit breaker unless it is an emergency, and then the QRH (Quick Reference Handbook) would specify which circuit breaker has to be pulled during an emergency.The 737 on the video was fromTurkeyMorocco, I never dealt with them, but even those guys are supposed to follow Boeing's procedures.
