Know the requirements and limitations of the aircraft. Does it need tarmac, an ILS, how much runway? Etc. Not any airfield is suited for landing of just any aircraft. Examine the airfield before deciding to go there. What is the cruising altitude of the aircraft? Can it fly over mountains or should it fly around them? Can it cross areas where there are no beacons? What is the range of the aircraft, when does the fuel run out? | Know the requirements and limitations of the aircraft. Does it need tarmac, an ILS, how much runway? Etc.

To plan a route we begin with a map, a ruler and a compass rose. On the map we draw a straight line between take-off and landing. For longer routes a string and a globe is used. The straight line is the fastest route. Unfortunately that route is almost impossible to navigate. The route must be divided in '''legs''', each leg begins on a radio beacon and ends on a radio beacon. | To plan a route we begin with a map, a ruler and a compass rose.

Near the straight line identify the VOR stations. A VOR station has a range of about 100 NM AGL. To prevent FROM navigation the legs should be less then | Near the straight line identify the VOR stations. A typical VOR station has a range of about 100 NM AGL. To prevent FROM navigation the legs should be less then 50 NM in length. To prevent continues tuning of your radio receiver and ever changing course the legs should be above 25 NM in length. If possible prevent NDR stations since they need continues attention. Prevent legs longer as 100 NM. | ||
Draw a line from station to station, each line is a leg of the route. Calculate the length of each leg. From the length of the leg and ground speed calculate the time for each leg. Use a compass rose to read the heading of each leg. Identify name, type, location and frequency of the stations. | Draw a line from station to station, each line is a leg of the route.
