6.1.4 <strong>DMAN</strong> TSAT versus AOBT<br />
<strong>Airport</strong> <strong>CDM</strong> <strong>DMAN</strong> <strong>Evalu<strong>at</strong>ion</strong> <strong>at</strong> <strong>Brussels</strong> <strong>Airport</strong> <strong>Zaventem</strong><br />
Figure 7 shows the standard devi<strong>at</strong>ion of the TSAT from the Actual OBT from 40 minutes<br />
before AOBT (left) to the AOBT (right). Both, the AMS in blue and the EUROCONTROL/DLR<br />
<strong>DMAN</strong> in black show a similar p<strong>at</strong>tern until about 13 minutes before AOBT. Thereafter the<br />
AMS system shows better performance. The explan<strong>at</strong>ion is th<strong>at</strong> the Ground Controller<br />
followed the AMS-system which is in actual oper<strong>at</strong>ion r<strong>at</strong>her than the <strong>DMAN</strong> system which is<br />
on passive trial. The <strong>DMAN</strong> TSAT was not visible to Ground Control during trial.<br />
