Can I please ask - something like a crane does this appear on any NOTAMS?
Next question - is there a type of GPS that can show relevant NOTAMS like temporary control zones or obstructions or is there a website pilots can go to where all relevant NOTAMS are shown on a map covering the area they are interested in?
And another question - if there was a low flying helicopter coming into the London heliport in bad weather would the control tower at the heliport be required to mention the NOTAM or are they not required to say anything to pilots?
