This lesson will teach you how to create a basic ground marking, the one that informs the pilot he has to hold during CAT II/III operations to ensure proper aircraft separation. There are generally a few taxiway signs too, which helps locating those areas also. CAT II/III separation is not that big issue within Flightgear, there's still no automatic ground traffic management, and aircraft crashing is not very expensive; but this is a real ground marking, and we will concentrate on the modelling phase, not on the functional aspects of that sign.
In this lesson you will learn how to create a basic ground marking.  We will us the one that informs the pilot to HOLD during CAT II/III operations to ensure proper aircraft separation. There are generally a few taxiway signs as well, which also help to locate these areas. CAT II/III separation is not that big of an issue in [[FlightGear]], there is still no automatic ground traffic management and aircraft collisions are not very expensive; but this is a real ground marking, and we will concentrate on the modeling phase, rather than the functional aspects of the sign.


There is no way [[FlightGear]] could position those ground markings in an automatic way. There is no database telling where they are and how do they look like. Each airport customizes ground markings position/orientation in order to get maximum efficiency and to help pilots getting correct informations without filling the ground with too much of them. Rationalizing communication effectiveness is vital to an airport. Therefore you will create and position them manually.

When looking from the air, those CAT II/III markings look like this:

They are generally put in the middle of the runway, following the taxiway yellow line, just before the CAT II/III operations area. Here the pilot has to stop and wait for directives coming from the ATC.

It's a simple red square with a big white CAT II/III writing, it's a lot stretched so that when looking from the aircraft, taxing over there, it looks quite proportional.


It is a simple red square with the text "CAT II/III" in large white letters.  It is stretched out so that when viewed from an aircraft taxing over it, it looks quite proportional.
