Hi.

Which category of aircraft does the NGX fall into on landing charts? I have been using C for my decision height information. Is this the right one,

 

Thanks.

There's been a fairly extensive discussion of this topic on this forum recently. The resulting conclusion was: it depends. Usually, the 737 NG is a category C aircraft, but under some regulations and with certain types of approaches, it could be classified as a cat. D. You might want to rummage through the forum a bit to see if you can locate that thread.

It depends on your landing speed. C is common for 737-7,8,900 whereas the 600 often is B

 

Look here for the ICAO rules. FAA differ a bit.

Thanks.

Will have alook through the forum

Basically there are two schools of thought, one group says you choose category by your actual Vapp, in which case 90+% of NG landings are cat C, other say that you choose by Vapp at MLW, in which case 6,7 are cat C, 800 is D and 900 is D as well.

Only one is correct, though, at least in the U.S.  See http://www.faa.gov/other_visit/aviation_industry/airline_operators/airline_safety/safo/all_safos/media/2012/SAFO12005.pdf

I was reading the part in the FCOM last night about approaches, and it said the -600 and -700 are class C and the -800 -900 are class C or D depending on landing weight

Depending on the individual operator's maximum landing weight.

That would make sense. That way the airplane is always in one category
