1 dot is .15 degrees from memory, your figures look like Localiser figs....but,and I say again,but who the **** cares,,,fly glideslope......land..end of...
flying is an easy job people with "theories" try and make harder.
As for green dot ...dont try and out think the plane or the people who designed it,if you were that clever you would be doing their job , then you could get the system to do it the way you would like it to work....
Speed request below G/d, few knot, maybe 10 is a good number , discuss and select ,if you both feel comfortable......it won't fall out the sky by the way, if not put the bloody flaps out ,don't try and complicate it, 1.23Vs ,1.05., blah,blah, bull,blah..yawnnnnn .
Feels nicer with flap/slat out, lower nose attitude, actually helps in TMA to see other planes, also feels better for crew and pax not to have 8-9 pitch attitude...also 1 less thing to screw up, 1 less thing to explain at subsequent board of enquiry.......
My aim is to get as much money as possible from the buggers and to try and make the job as easy as it could or should be be.
