Thank you all for the responses.
Flyingchanges,
Why not?
Surely you cannot get a clearance to shoot a visual approach with 4KM visibility.
All I'm saying is in the middle of the approach if your ILS signal was lost, you could continue if visual. Why can you not ask for a visual then?
The only reason I say you should ask for it, is because if something goes wrong, and you were cleared for the ILS approach and the signal was lost, technically you were not legal to continue, UNLESS you had notified ATC and requested to continue visual.
This is just how I understand it and stand to be corrected maybe.
This is how someone explained it to me, please advice if everyone agrees with this.
Your reported RVR is 1400 meters. Shooting a NPA you require 1500 meters on the chart.
You are almost certain that the reported RVR seems to be unreliable like it is in many places in Africa.
You shoot the approach till the outer marker and now are visual.
You are still legal to continue because you are visual.
Isn't it the same?
Please advice.
Again, thanks guys.
