In this case, will the average slide delpoyment time then be added on to the total time it took for the evacuation?

I reckon the deployment time is between 5 and 10 seconds, after seeing a few videos of some slides being deployed. Perhaps the larger ones on the top deck and those on the overwing exits could take up to 15 seconds?

So the test is failed, that what you want to say? :rolleyes:

The slide deployment time depends on the slide. I don’t have a number, but after the EASA and FAA approved the test (official time 78 seconds) it seems to be OK. The A380 evacuation slides were object of lots of development. I saw early slides when I was trainee in Hamburg in 2000, already with a moke-up in the real size of the A380 (of course only a section).

I heard of deployment times between 3 and 6 seconds.
