The chart shows RWY18L.
Plane is lined up on RWY03.
Runway numbers are assigned based on the magnetic heading of the runway rounded to the tens and are reciprocal (180°).
RWY03 will be 30° (rounded here) in one direction, and named RWY21, 210° (rounded here) in the opposite direction.
If the name of the runway on the chart is 18L, it means that the runway heading will be approximately 180°, plus or minus 4 or 5.
Taxiways are not unique to the airport. Many airports have a 'H' taxiway.
