The first issue I noticed is that the lead and infobox both state two different runway lengths for the same runway. The infobox says the runway is 1,200 m long whereas the lead says it's 1,440 meters long. Please correct whichever one is wrong.
Fixed. The confusion is because only 1,200 m can actually be used (as described in the facilities section), but the longer is the correct number. Arsenikk(talk)00:00, 24 November 2012 (UTC)reply
"It has of a 1,440-meter (4,720 ft) runway numbered 04–22..." – Remove the "of".
The following two sentences could be combined: "The following thirteen years Brønnøysund only saw occasional landings. Norwegian Air Lines started a service from Bergen to Tromsø on 7 June 1935, which included a stop at the harbor in Brønnøysund." Would suggest saying something like "Brønnøysund only saw occasional landings until 7 June 1935, when Norwegian Air Lines started a service from Bergen to Tromsø with a stop at the harbor in Brønnøysund."
"The aircraft turned out to have too little capacity" – Consider saying something more concise, like "The aircraft turned out to be too small...".
My thought here is that the aircraft were replaced because they had too few seats (=capacity), but if other people don't understand it the way I do I can always convert to small. For a aviation-oriented audience I would have written "too low pax". Arsenikk(talk)00:00, 24 November 2012 (UTC)reply
It now says "The aircraft turned out to have too small..." – The "have" should be changed to "be" in order to correct this grammatical error. Or you could say "The aircraft's passenger capacity was too small..." —Compdude12318:49, 28 November 2012 (UTC)reply
In the second paragraph it says "Seaplane routes resumed from 1947 using the Junker Ju 52." First of all it would make more sense to say "in 1947" instead of "from 1947;" also, pluralize "Junker." —Compdude12318:49, 28 November 2012 (UTC)reply
"The Sud Aviation Caravelle was about to the phased into use..." – The "the" should be changed to a "be" so that the phrase makes sense. And I would suggest saying that the Caravelle was a jet aircraft. —Compdude12318:49, 28 November 2012 (UTC)reply
"As on of very few regional airport, Brønnøysund Airport received a restaurant." – This sentence doesn't make much sense, and it should be rewritten. Is it trying to say that Brønnøysund Airport is one of the few regional airports with a restaurant? —Compdude12318:49, 28 November 2012 (UTC)reply
"As the first airport in the world, Brønnøysund received SCAT-I on 29 October 2007." What is SCAT-I? Since it's a red link you should explain what that is. It is explained in the "Facilities" section but that's later in the article. —Compdude12318:49, 28 November 2012 (UTC)reply
"Thon Hotel Torghatten opened in October 2009 and an airport surveillance radar was installed in 2010, as the first at a regional airport in Norway." Change to "Thon Hotel Torghatten opened in October 2009 and an airport surveillance radar was installed in 2010, making Brønnøysund the first regional airport in Norway to have one." —Compdude12318:30, 29 November 2012 (UTC)reply
There are many instances in this section where it says something like "So-and-so introduced such-and-such from April 2005," for example. It should really say "in April 2005" or "starting April 2005." The word "from" isn't really the right word to use in cases where the statement doesn't describe a period of time where the event takes place. —Compdude12318:30, 29 November 2012 (UTC)reply
Thanks for the comment. "From" is a Norwegianization and when I am reading in Norwegian and writing in English my grammar tends to drop a few notches. Arsenikk(talk)10:54, 30 November 2012 (UTC)reply
So far, so good. Looks like there's just some minor changes you need to make. Also, I take it you have checked all the references to make sure they provide proper verification for the text in question, right? I can't really do this myself since most of this article's sources are in Norwegian, a language I don't know. —Compdude12318:30, 29 November 2012 (UTC)reply
I did think twice about this, but I included it not so much because Brønnøysund was the origin but because it was a "shuttle service" based at the airport. I agree that accidents shouldn't be included just because they originated at the airport. Arsenikk(talk)10:54, 30 November 2012 (UTC)reply
