Quick question on STM

Airbus A330 maximum range 6100 stm (9817km).
What does STM stand for?

Re: Quick question on STM

Or slightly more correctly - Statute Mile, because it's defined by Statute.
The statute mile was so-named because it was defined by an English Act of Parliament in 1593, during the reign of Queen Elizabeth I. The statute states: "A Mile ſhall contain eight Furlongs, every Furlong forty Poles, and every Pole ſixteen Foot and a half." It was thus 1760 yards (5280 feet, about 1609 metres). For surveying, the statute mile is divided into eight furlongs; each furlong into ten chains; each chain into four rods (also known as poles or perches); and each rod into 25 links. This makes the rod equal to 5½ yards or 16½ feet in both Imperial and U.S. usage.

Re: Quick question on STM

As opposed to air miles, the distance the aircraft actually covers. Well that's simple enough so thanks guys Smiley

Re: Quick question on STM

Nautical miles (nm) , is what you'd normally expect an aircraft range expressed in.

Re: Quick question on STM

That's very true and on the Airbus site that's what they use...3,300nm
I was quoting from Monarch's site....2,700stm
Interestingly Airbus' A320 has a greater range than Monarch's A320, 6,150km as opposed to 4,335km Undecided Probably due to seating arrangements.

Re: Quick question on STM

Maybe because Airbus quote for typical 150 passenger capacity and Monarch manage to squeeze 180 in there.

"nm" is nanometres which is not much of a range!
According to some the correct abbreviation for nautical mile is "nmi".

Re: Quick question on STM

Is it still nautical miles if the plane flies entirely over land?
If so, why?

Re: Quick question on STM

Yes, simply because;The nautical mile (symbol M, NM or nmi) is a unit of length that is about one minute of arc of latitude measured along any meridian, or about one minute of arc of longitude at the equator. By international agreement it has been set at 1,852 metres exactly (about 6,076 feet).  [source: https://en.wikipedia.org/wiki/Nautical_mile].
i suppose, if you fly high enough, you might fly more 'air miles' to cover the same 'surface distance', in particular, nautical miles are nearest the original definition at sea level.
