It sure looks like the pilot was taking off from a high-density altitude airport with no flaps, downwind. -- Jay Honeck Iowa City, IA Pathfinder N56993www.AlexisParkInn.com "Your Aviation Destination" I watched it a couple of times... I wouldnt discount that he caught some sort of sheer or something else coming over the terrain. A lot depends on how he was loaded and the DA...but there could be other factors. Robert |

Even on a hot day at 1200 feet it should have had the ability to get in and out of a 4000 foot strip with only moderately rising terrain and a *light* tail wind. I can only guess, but two guys I know flew a Cherokee 180 into a grass strip in the UP of Michigan for a fishing trip. On the day they came home it was HOT and humid. Basically they were high, hot, humid, and heavy. The pilot was trying to give the trees at the end of the runway a wide berth, but they had neither the speed nor power. The right seater kept telling him to keep the nose now as he was easing it up. The almost cleared the trees.

Actually they had a 6" dent just inside the last rib. The pilot once made the statement, had the right seater kept forcing him to keep the nose down, they'd never have made it. I wonder if this wasn't a similar situation but without some one reminding the pilot to keep the nose down. Roger Taking the last item first; yes, it is very possible. One day, about 25 years ago, I was out with an instructor practicing in a Cessna 150M. The wind was nearly 20KTS and he, being a bit of a "good ol' boy", elected to demonstrate a downwind touch and go. The terrain is southeastern Florida is *very* flat, with the usual urban ground clutter sticking up, so it is fairly easy to have a fairly sharp gradient in the wind as you climb out of ground effect--which works in your favor when you go the right direction, but... He had been away for about a month, and flying only twins which have almost no p-factor with all engines running. As we reached the top of ground effect, rapidly losiing airspeed and in a wings-level left turn, he announced: "We're in trouble!" To which I responded: "We're also in a hell of a right slip!" He then got his right boot down firmly on the rudder pedal, and we flew away without further incident--although there were no more downwing touch and goes! The temperature and humidity appear to have been sufficient to give plenty of importance to a DA calculation--I know that it is always required--and probably enough to suggest a fudge factor for the effect of humidity on available power and required mixture. The same Fox station had historical weather in Sacremento available, so here is the range of weather for yesterday, August 31, 2007: Temperature Mean Temperature 85 °F 74 °F Max Temperature 99 °F 90 °F 104 °F (1998) Min Temperature 71 °F 57 °F 50 °F (1957) Degree Days Heating Degree Days 0 0 Month to date heating degree days 0 0 Since 1 July heating degree days 0 0 Cooling Degree Days 20 9 Month to date cooling degree days 329 303 Year to date cooling degree days 979 967 Growing Degree Days 36 (Base - ) Moisture Dew Point 56 °F Average Humidity 43 Maximum Humidity 61 Minimum Humidity 24 Precipitation Precipitation 0.00 in 0.01 in 0.11 in (1964) Month to date precipitation 0.00 0.06 Year to date precipitation 6.60 12.04 Since 1 July precipitation 0.01 0.11 Snow Snow 0.00 in - - () Month to date snowfall 0.0 Since 1 July snowfall 0.0 Snow Depth 0.00 in Wind Wind Speed 5 mph Max Wind Speed 15 mph Max Gust Speed 18 mph Visibility 10 miles Key: T is trace of precipitation, MM is missing value Source: NWS Daily Summary Peter |

![]() "Airbus" wrote in message ... I'm voting for overweight. After what appears to be a relativly long roll, you can see the plane mushing and stalling trying to climb. I saw the video on a computer without sound, so I don't know if they said how many people were on board, but this plane, even with no flaps, should climb out just fine. What about watching this type of video - is it useful for our awareness as pilots? I tend to think it is, but that's just a personal opinion. Where I grew up, the State Police used to do an auto safety presentation every year to students who were about to get their driving licenses. They would show gory, shocking films of accident scenes, hoping to impress the young, future drivers. They don't do that any more, but I don't know if this is because they feel it was not effective, or because they are concerned it is no longer socially acceptable. . . Probably because of political correctness. I presume that the level of effectiveness was related to how well the causes were known, and how well the decision tree was reconstructed. If they tried to fill in too much data that they did not fully verify, or tried too hard to make a point, then their credibility was lost. OTOH, if they avoided reaching too far, or preaching too much, they could have substituted for a lot of life experience. I don't know which they really did, but since they should have had more than enough cases to choose from, I suspect a sort of middle ground. Peter |

Yeah, they would hear the engine sputter even if it was a crash of a glider. You have to wonder on cases like this if it wasn't that they heard the engine sputter as the prop started chewing up the terrain. Sounds like it was a case of, "Come on baby... Come on... You can make it... A little more... Ahhh ****!" You got it! Ahhhh ****!!! |

I was at a poker run a week ago in my A36 with 5 people we took off at BNG
(banning) we were behind a Cherokee 140. We watched the 140 almost crash. I got on the radio and asked if he was in trouble he replied back yes. I told him keep the nose down 3 or 4 times as i was watching him. He made it thank god. My Bonanza has a 1450 useful load with the 5 people and not much fuel we took right off with no problems.

Looks like the max temp yesterday was 98°f, pressure was 29.8 or so, winds were out of the south or south-south west. There are no reported winds at that airport and I've never, ever seen the winds there be the same as in the valley. If you are looking at temps and wind directions from the sacramento area (which is what you get on weather.com, etc) you can throw those in the round file. We're always a bit cooler than Sac and the winds could never be the same because there is a foothill range between the two and a 1000 foot elevation difference. You guys on this board are as bad as the people on the news with wild &*($ guesses that are useless. Also looks like they were taking off 13, so they had a right cross wind.

There is no take off maneuver even short field at high altitude in mine that calls for any use of the flaps. That's interesting -- I never realized that Bo pilots didn't need to use flaps for departure. I presume there is something about the wing that makes them unnecessary? Both Vx and Vy for virtually all light aircraft are without flaps. The only time a POH will recommend flaps for takeoff is short field, and then the speed used is a speed below Vx. This is a speed to clear close in obstacles and does not result in best angle of climb. It is a compromise speed used because the short field distance doesn't allow the aircraft to accelerate to the greater Vx speed. You might call this "compromise" with flaps speed Vxwithflaps, but they don't. Mostly the aircraft that have this "lower than Vx with flaps speed" used for takeoff have fairly powerful engines. My Cessna 185, for instance has this speed published and the POH shows 20deg flaps for short field. But once past the close in obstacles one should accelerate to Vx and raise the flaps to clear far obstacles. If the airspeed is in the green arc, the airplane will climb better without flaps. Karl |

Most takeoffs are downwind because the socks at each end of the field usually face away from each other. Do you want downwind 13 or downwind 31?? High-density altitude airport? If this wasn't so sad, I'd laugh at that comment. Its amazing how much ignorant statements you see from pilots, often worse than the news. -Robert |

In a previous article, Mike Granby said:
Another witness mentioned an engine sputter Whatever the cause of a crash, there's always someone who hears the engine splutter... Have you ever noticed how much the engine note changes as a plane taxis or takes off past you? You get very different engine noises depending on whether the prop is moving towards you or away from you. It's no wonder naive observers think the engine was spluttering or dying. -- Paul Tomblin http://blog.xcski.com/ ....if Paul's really talking about truly average people, then they'd probably die in either case, because common sense isn't. -- Derick Siddoway |
