I wish most pilots would understand the differences of "request" and "require".
Both sound the same but they are DIFFERENT.
Request loosely means I would like/I have different options available to me.
Require loosely means I need/I have no other options available to me.
If you request weather deviation Left it would mean that deviation to the right could also be an option.
Require deviation Left means that is the only direction I can go. Right is NOT an option.
This can be put into other pilot needs. R/W etc...
