If VFR aircraft requests assistance when it encounters or is about to encounter IFR weather conditions, determine the facility best able to provide service. If a frequency change is necessary, advise the pilot of the reason for the change, and request the aircraft contact the appropriate control facility. Inform that facility of the situation. If the aircraft is unable to communicate with the control facility, relay information and clearances.
The following must be accomplished on a Mode C equipped VFR aircraft which is in emergency but no longer requires the assignment of Code 7700:
TERMINAL. Assign a beacon code that will permit terminal minimum safe altitude warning (MSAW) alarm processing.
EN ROUTE. An appropriate keyboard entry must be made to ensure en route MSAW (EMSAW) alarm processing.
