Near Vertical Takeoff
Skip the ad when you can to get to the video - looks like Grant County International Airport, near Moses Lake, Washington.

Not something you would see with passengers inside! I would love to see a side view of that climb, I wonder how fast it's shedding speed? Nice wing bend though. ;-) |

Near Vertical Takeoff
From CNN: "Hero pilot saves the day."
From a passenger interviewed in the terminal: "We almost died!" I can do that in my glider, though not for quite as long... On 6/13/2015 6:13 AM, Charlie M.

LOL @ DAn.
Awesome! Goes to show without all the ballast (human bodies) these planes have plenty of extra power. |

There's also the regulation that large twins have to be able to continue a takeoff from V1 [1] on a single engine at max all-up weight and the given runway length, wind, temp etc. If you actually have twice that trust, as you usually do, it's jam. I note that the A380 has an *extremely* leisurely climb out compared to the modern twins. It only has to have 33% more than the bare minimum power, compared to 100% more for twins. [1] if an engine fails below V1 then you stop. If above V1 then you continue, but you must accelerate to at least V2 before actually lifting off. |

I can do that in my glider, though not for quite as long... Yes you can! Do a winch launch on one of those specially modified European winches that use over 11,000ft of line, hold that climb for 2 minutes and end up at over 4,500ft. I bet the jet cannot do that! Uli |

Wow!!! I'd love to try that!

Uli What - 2250fpm? Most modern twinjets do that easily. A full thrust takeoff in an empty 747SP cracks 4000fpm. Even if you allow 30 seconds for the takeoff roll - about right at light weights - 4500 feet two minutes after brake release would be easy. OTOH, I'm stunned at the lack of scepticism about the video. The climb will be nowhere near vertical. 150kts indicated is 15000fpm if vertical. It's nowhere near that. The climb is likely about 5000fpm - 50kts in glider-speak. That's about 30 deg climb angle. Perspective foreshortening due to long focal length lenses is a wonderful thing. That's how all those aeroplanes survive 60 deg drift landings in HKG on those Youtube videos. GC |
