CX A340 YVR-HKG Flies 10 Hours with cracked windscreen

[plain-plane]

Just a brief comment on the use of MEL airborne

On my type/company it would be considered very prudent to consult the MEL and DDPG en-route. That is where you will find information on down grating of, P-RNAV, MNPS, RSVM, CAT II/III.
But who needs to know that anyway…

I.E.: What will an INOP windshield wiper do to you?… or in a similar case to above… is it any good on a window that has crap’ed out on you?
Can you or can’t you then consider it operational…?
On the B73/NG: no wiper means no CAT II/III…
