10 Weather

Knowledge of weather conditions likely to be encountered during flight is

essential to the safe operation of aircraft. However, weather conditions change

and therefore a convenient system to supply the latest information is required.
To be effective these sources and the terms used must be globally understood.

10.1 ATC ATIS VOLMET

A pilot in flight can gain weather information from several sources; the main
sources are: ATC, ATIS, VOLMET

In all of these, standard met terms should be used and the information is

transmitted slowly and enunciated clearly so that the data can be written down
by the flight crew.

10.1.1 Request from ATC

For example, when returning to Herning from Stauning, you might be receiving
a radar service from Karup Radar. In order to decide how you will approach

Herning you could request the weather from Karup.

“Karup Radar, SEGPD request Herning weather”
“SEGPD, the Herning 0950 weather, surface wind 360 degrees 5 knots, visibility

10 kms, Nil weather, scattered 2500 feet. Runway 09 in use, QNH 1010”

10.1.2 ATIS

In order to reduce the workload on controllers, a recorded message is

transmitted continuously on a discrete VHF frequency or on a VOR frequency.
Pilots are expected to listen to the report before contacting the appropriate

aerodrome controller. Every time the data is changed a new code letter is

allocated.
If Herning had its own ATIS, a typical example sounds like this:

“This is Herning Airport information Bravo at 0820. wind 210 degrees

10 knots. Visibility 8 km bkn 1200 ft temp 15 dewpoint 14. QNH 1019”
