Navigation
We extend the route so that we fly to EKLV and from there back to EKHG.
We get TT:
- EKSD → EKLV 344°
- EKLV → EKHG 128°
9.6.3.2 Distance
Now the route is almost measured. We just miss distances.
In aviation, distance is most often given in nautical miles (NM).
The size of a nautical mile is obtained by dividing the distance from the equator
to the geographic North Pole into degrees, and there are 90 degrees.
These 90 degrees are divided into minutes, so that each degree is 60 minutes.
Then we get 5400 minutes from the equator to the North Pole. If the physical
distance of approx. 10.000 km is divided by 5400 minutes, we get a nautical mile,
which corresponds to approx. 1.852 km.
In aviation, you can also meet distances given in statute miles (SM). 1 NM
corresponds to 1.151 SM, and 1 SM corresponds to 1.609 km.
In certain situations, a distance will be given in feet (FT or ft). 1 ft corresponds to
0.305 m.
We have the following designations and measurements for distances:
Km / NM 1 nautisk mil (NM) = 1.852 km 1 km = 0.539957 NM
MN / SM 1 NM = 1.151 SM (statute mil) 1 SM = 0.869 NM
Km / SM 1 SM = 1.609 km 1 km = 0.622 SM
FT / m 1 FT/ft (feet / foot) = 0.305 m 1 m = 3.279 ft
