Divide its magnetic heading by 10, round it to the nearest whole number and you will usually get the runway number.

For example, if the magnetic heading is 345° then 345/10 = 34, 5.

So the runway number will be 35 which will be a runway used for landings (and takeoffs) to the north.

@Sahana.

The direction for both numbers 13 and 31 will be the same,

Just draw a line with 130° clockwise, and then draw the line 310°. You will see both are in the same direction in two opposite coordinates.

Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit.

S 45° E means 90 + 45 = 135 135/10 = 13.5 so its nearest value 13 and 360-45=315 315/10= 31.5 near value 31.
