For VFR flights within LUDZA AVP ATZ airspace frequency 123.950 MHz shall be used as the common traffic advisory frequency (CTAF) by the pilots for self-announcing their positions and intentions in the blind or for air-air communications in order to exchange information.

A pilot should continuously monitor air-air communication on frequency 123.950 MHz at least 10 minutes before arrival at LUDZA AVP ATZ or its crossing in order to receive information about the air traffic activity situation and should transmit in the blind the following information:

A. Inbound traffic:

1. location of the aircraft, altitude and further intentions - 3 minutes before entering LUDZA AVP ATZ;

2. heading to be used for landing;

3. entering traffic pattern and altitude (crosswind, downwind, base leg and final);

B. Outbound traffic:

1. intention for departure;

2. heading to be used for take-off;
