The Airfield: Structure, Traffic Rules and Procedures
1. Construction of an Airfield
1.2. Taxiways
Taxiways are the connection between the apron and the runways of an airport.
The taxiways of modern airfields are clearly numbered by letters and numbers. Normally there are yellow signs next to the taxiways at the crossroads of these routes, which mark the respective taxiways.
The taxiing of aircrafts is subject to approval by the tower or corresponding ground controllers who coordinate this part. Taxiways are one-way streets and are only used in one direction at a time. If used correctly by all parties involved, head on traffic can therefore never occur.
Examples from IL-2 Sturmovik
The following pictures show the taxiways on two IL-2 Sturmovik airfields.
Examples from DCS
The taxiways on two DCS airfields are shown here. Left from the Caucasus Map (Anapa Vityazevo) and right from Normandy (Saint Pierre du Mont).
