Field-Laying Procedure

The sequence for laying an entire field is as follows:

1. The main runway

2. The lateral taxiways

3. The taxiway that is parallel to the runway

4. The parking stands and storage areas

The above sequence may be modified in the interest of gaining time in the overall installation by laying the main runway and the parallel runway at the same time. Then the lateral taxiways and parking area can be installed.
