IVAO Belgium

• Start up approved: Now we can start the engine

• Cleared:Our flight to Amsterdam has been approved

• Helen 2C: This is the SID from Brussels to Amsterdam.

Helen 2C is a standard departure from runway 25R so the runway itself is no more mentioned in the message.

• Climb FL60:We can climb after takeoff to flight level 60 (6000ft) with an altimeter setting of 1013.2 hPa. (default air-pressure)



Note:

Below 4500ft in Belgium and below 3000ft in The Netherlands, the altitude is expressed in ft (ALT). The altimeter must be set to the local air-pressure level (QNH) which is 1012 hPa in our case.  This setting can be found in the ATIS. Above 4500ft (or 3000ft in NL), the altitude is expressed in flight levels (FL) and the altimeter must be set to the default air-pressure value which is 1013.2 hPa (29.92 inches).The number following the FL must be multiplied by 100 to get the real altitude. So, FL60 means 6000ft and FL380 means 38000ft.

• Squawk 4401: This is the code you must enter in your planes transponder.

It always consists of 4 digits and is used by the controller to identify you on his radar screen.
