I was under the impression (old memo? Misinformation?) that we could either de-ice with flaps retracted, or we could choose to extend them to takeoff setting and use the 76% holdover table.
Now I’m hearing, we’re supposed to always leave them re-retracted (and use the 100% holdover tables) .. unless we feel the flaps need de-icing, in which case we extend to 45° whilst de-icing, then set them to takeoff setting and use the 76% tables.
