Such instructions should include options for cases where radio contact is not mandatory and a voluntary radio-communication has been interrupted without proper termination of the contact. These instructions should clarify what kind of information may be used for providing alerting service to aircraft which have not filed a flight plan, based on the available technologies and local operational conditions (e.g. use of emergency transponder codes or declared emergency of available communication channels).
