the deployment of a thrust reverser discourages an attempt for a go-around and we find ourselves in a *cul-de-sac* where the apparent only option is to stick to the landing and try to stop before the end of the runway
This doctrine came about as a result of the Cranbrook accident where a 737 cancelled reverse and attempted a go-around upon seeing a snowplow on the runway. Back in the air one of the engines fell back into reverse and the affected throttle snapped back to idle with such force that it broke the captain's thumb
Some hundreds of posts ago, I suggested waiting for spoiler confirmation before selecting reverse to preserve the option of a rejected landing since as we have seen, an announcement of "spoilers nada" on a critical runway after reverser deployment is not much more than an announcement that we will be going off the end.
Using Lemurian's 72m/s at 140 kt. and his 5 seconds to cancel reverse and stabilise in forward idle, we would be using 360 m less runway.
To that we would have to add a few seconds of waiting for spoilers, which may result in recalculation of landing distances on contaminated runways where spoiler usage is factored in.
