Countries charge for planes to fly through their airspace even if the plane does not land. Different countries levy different charges, therefore plane companies consider a number of different routes and calculate the associated charges with each route. The formula used to fly over Europe is considered and an example calculation provided.…

There are strict limits on the number of hours that pilots can work. A formula is given which is used to calculate 'stick' time, the actual working time for a flight with a scheduled flying time of t minutes. Students are required to use this formula to solve a number of problems posed. Students are asked to graph the relationship…

Due to problems in the manufacture of tinplate coils, the edge of the strip can be slightly longer than the centre. This causes a 'wave' on the wall of the coil but can be rectified by differentially stretching the strip to make the edges flat. Students are required to apply Pythagoras' theorem to find the radius…
