Russian jet screws up performance

I know this doesn’t really apply to HK but this is what happens when the incorrect RTOW is used. It’s a short video almost ending in disaster

When I worked for Boeing over 3 years ago I wrote a comprehensive article on how to help prevent these types of incidents from continuing to happen. Boeing flight operations management completely ignored the suggestions. Their head will continue to be buried in the sand until such time that a B777/787 goes off the end of the runway and explodes killing all aboard due to such an error. Qatar very nearly did that in Miami in 2015. MK Airlines did do it in 2004. It's just really sad. Boeing flight operations management and flight standards have very little actual airline operating experience, especially on widebody aircraft, so they fail to recognize the threat.

Maybe you didnít give the yanks a proper tongue lashing!!
They just didnít understand you were speaking for the queen.

I donít think you can ever completely prevent finger f**k errors and confirmation bias.....like 227 vs 277.
What surprises me more watching the video is the crew doesnít appear to add any power although they may have at the very end.
Maybe halfway down the runway next time perhaps?
Meh....this doesnít look/feel right and just punch it?

I couldn’t agree more , some carriers use a timed acceleration to either 80 or 100kts vs thrust setting . It confirms if acceleration is normal , especially useful in low vis operations where you have limited visual clues, or if there is an an EPR icing issue , or perhaps a dragging wheel or brake during contaminated runway ops

Very basic general rule of thumb. If you haven't hit 2/3rds of Vr by atleast halfway down the runway something is not quite right

That's what a Victor K1 takeoff used to look like out of Akrotiri!

I though that most recent types (350, 787) have a take-off monitoring function that would alert the crew of abnormal performance before they become an issue.

A clock and the rule of thumb...
