what is this "+" mark on B737 cockpit panel?
I've noticed that on the FWD overhead and main panel of B737-700, there are lots of " + " mark on the panel. (at least one on each plate)
example) under gear handle where flap limit speed is shown
FLAPS LIMIT (IAS)
1 - 250K
2 - 250K
+ (<-- this mark )
5 - 250K
what is this?
I couldn't figure it out nor find any information.
Please help my curiosity....thx
