before landing check list - I should clarify, the info came from a FDR, with some input from photographic analysis. Frazzled, I pondered that portion, not well worded as you say, but from what else was said I concluded that he was inferring that 20% TQ is more or less idle. I would expect that 20% TQ could be in the range one might see with throttles at flight when sitting on the ground, perhaps another reason he had for saying they were at idle. Know nothing of Blackhawks myself.
