Starter Puzzle Here some aerial pictures of various airport runways Dr Frost has been on. Can you work out what the numbers mean?  Heathrow - LondonJFK – New York Hilo Airport - Hawaii EuroAirport – Basel- Mulhouse-Freiberg Portland International Airport - Oregon Beijing Capital International Airport Rhodes Airport - Greece If we add a 0 on the end, we get the angle clockwise from North the runway faces!

Bearings  A bearing is an angle measure clockwise from North. We use 3 digits. Historical reason for 3 digits? Bearings used to be transmitted digit by digit from ship to ship. Were some bearings two digits, it would be ambiguous whether two digits was intended or a digit was lost in transmission. ?     A B C D E B from A000 A from B180 C from A090 D from A225 A from D045 A from E135 E from A315 The bearing of: ? ? ? ? ? ? ?
