In fact Maersk did utilize the extreme STOL properties of the Dash-7, mainly at CPH
For some years they operated in their own way when the wind wasn't strong. They landed on RWY 30, coming in at a 6 degrees glide slope right over the city, and ended the landing roll way before they crossed the two main runways 04/22 L/R.
Taking off from RWY 12 they used the same few hundred yards of 12/30 to climb right over the city center.
The low noise and steep climb and descend properties allowed that unusual way of operation, and it saved a lot of time and fuel on their domestic flights to destinations mostly west or north-west of CPH
The Dash-7 could that way often be faster than a 737 or DC-9 on the same sector, for certain if the 737 / DC-9 had to be put on hold for landing on mostly 22L or R. Also because taxi distance to and from the domestic terminal was very short.
But after a few years operating that way the authorities didn't allow it any more. ATC was considered too complicated. They had to mix with all other traffic at CPH
. It ended the Dash-7 days at Maersk, and they were replaced by F-50s which were cheaper, faster, more fuel efficient and slightly larger planes.
It was loved by the public. It earned the nickname "Windmill Park".
The Dash-7 is still a necessity for the air traffic infrastructure in Greenland where runways are extremely costly to build.
