Caro Rui,
I hope and trust you are not too much upset when I reverted your change to the out area of Ovar Air Base. You may wish to refer to https://wiki.openstreetmap.org/wiki/Aeroways#Traps_to_avoid
Also, be aware that maproulette is not moderated, anybody can post their personal whims there without realising the consequences! Generally, one should think twice before entering upon a request in maproulette.
Kindly from Ansião!
