In some projects (flight simulator, texts, aticles, games etc.) I found a lot of wrong runway indicatiors, Why? If I see "Runway 42" it sounds like 2+2=7 for me. In aviation we use magnetic heading for exapmle: Runway 32 is located in 315-324 magnetic heading section. But what's wrong with 42? Revise your school knowledge. The circle has 360 degrees (like Earth) so heading 420 looks at least strange. If you have heading 354 you should round to 350 (with maths rules).
Recapitulation:
Runway indicator | Magnetic heading |
01 | 005-014 |
02 | 015-024 |
03 | 025-034 |
yy or xx+1 | xx5-yy4 |
36 | 355-004 |
