To locate an Aerocache, it will first help if you enable the Aerocache tracker. Click missions, then click Aerocache Hunt to find a list of all the Aerocaches that can be located. Click on an Aerocache and the first thing you should take note of is the description (is it located at the airport, on a beach near the sea or elsewhere meaning it will be inland). Then, if you wish, you can use Bing to help you narrow down its location faster. Click the link, then click on Bing maps, and hopefully the location will be placed. However it is not always accurate and sometime has difficulty finding it. Finally, you should click start hunt which will take you to the nearest airport. If the location of the Aerocache is at the airport, I suggest you exit the aircraft with "E" and run around to collect, otherwise take note of how close the Aerocache is. Click "M" to bring up the map, zoom in, then right click the approximate distance the Aerocache was away in any direction. Then hit "M" again (note if you found the location on Bing, click there). Once you have done that the Aerocache will either be closer or further away. If it is close you have clicked in the right direction and you should go on the map again; right click nearby until you can place the aircraft within 1km of the Aerocaches. From there it should be easy to find and fly through. If the Aerocache is further away, then click in the other direction and it should get closer
