Hi there,
I'd need some feedback regarding the following question - I believe that the answer provided is incorrect.
A Boeing 747-400 has a wing span of 64.4 m. When considering relevant obstacles for the take-off flight path what is the semi-width of the zone at a distance of 1500 m from the TODA?
QDB says that the correct answer is 277.5 m but I come up with 279.7 m applying the following formula:
Domain 1/2 width = 60m + 1/2 wing span + 0.125 D
Domain 1/2 width = 60 + 32.2m + (0.125 x 1500m)
Domain 1/2 width = 279.7m
Thanks
