Not going to presume to read the schematic, which does seem to combine conditions such as speed < 260 comb8ned w Gear lever Down, but doesn’t show a Gear Lever Down over a changing speed condition.
Well, yes the schematic does inexplicably show this...
LESS than 260 KTS on the ADR AND Lever down....
There is no wording one way or the other ...a combination of less than 260 KTS on both ADR's AND the lever down will open the hyd valve....
