Small point of order - the magenta-coloured line is actually used on Boeing's FMS displays. Airbus FMGS uses a line which if I recall correctly is either white or green.
Yeh, green and missed Approach is blue and Sec flt pln is white.
There is a lot of magenta about though, in about five seconds somebody will state which flashy bits are magenta, there is also a yellow temporary line - which is there when you are making slight adjustments to the flight plan invariably in PLAN but also / or in the SEC FLT PLN and they turn - grren? Normal when you insert it, (othewise known as tmpy)
(actually, am gonna take a look to see what is magenta on the A320)
Well, I have just returned from my trip on the internet - looking for Magenta, there is a whole world out there of Magenta colouring (and we are stuck on avionics):
Its a sort of Orange pink to shocking pink, to flourescent day-glo in yer face pink.
found on the PFD, ILS
the Donut is magenta
Spd select ind is magenta unless you - - - ? and then its - - - ?
Am trying to think what is on the ND that is magenta. . . .?
Next speed is magenta
Glideslope is magenta
LOC is magenta
ILS ident and freq is magenta
wpts not in the flt pln display magenta
Alt constraint arrows magenta - if not selected not the FCU
decell point (a dot on the ND) is magenta
Alt constraint if predicted to be met is magenta
DME/TACAN on the ND in magenta - if not part of the flt pln.
VORs, Airports, asterisk magenta
NDB.........................magenta
selected heading (not the one you are on) magenta
I wonder what Orville and Wilbur would have thought about magenta.
