Is that really the case? Haneda isn’t that big an airport. Narita is far larger.
nm: I have google. It’s the busiest.
As in most incidents like this, there had to have been multiple failures, and the investigation is beginning to find them.
Haneda control tower had a monitoring system which apparently could detect an incursion and apparently did, alerting ground controllers with a blinking indicator when the Dash 8 went past their hold position. But controllers apparently didn’t notice the warning.
Haneda only has some international flights, but many, many more domestic ones than Narita.
It may just be chance sampling error, but I’ve been watching a few of the Mentour videos and noticed…
Qantas 747 Bangkok (1999) off end of wet runway
Delta MD88 La Guardia (2016) off snowy runway
JAL A350 Haneda (this thread)
In all of these incidents the aircraft stopped without any injuries, but the comms and PA failed, leading to uncertainty and indecision both inside and outside. In the first case the nosewheel collapse caused damage, in the other cases I think it was general power failure. It seems like it would be pretty trivial to have some kind of emergency backup between flight crew and cabin crew and ATC. Even if it’s just cellphone based, but something where you’re not scrambling to look up the relevant phone numbers and you can communicate with all crew simultaneously.
