10-2-8. RADAR ASSISTANCE TO VFR AIRCRAFT IN WEATHER DIFFICULTY
If a VFR aircraft requests radar assistance when it encounters or is about to encounter IFR weather conditions,
ask the pilot if he/she is qualified for and capable of conducting IFR flight.
If the pilot states he/she is qualified for and capable of IFR flight, request him/her to file an IFR flight plan
and then issue clearance to destination airport, as appropriate.
If the pilot states he/she is not qualified for or not capable of conducting IFR flight, or if he/she refuses to
file an IFR flight plan, take whichever of the following actions is appropriate:
Inform the pilot of airports where VFR conditions are reported, provide other available pertinent weather
information, and ask if he/she will elect to conduct VFR flight to such an airport.
If the action in subparagraph 1 above is not feasible or the pilot declines to conduct VFR flight to another
airport, provide radar assistance if the pilot:
(a) Declares an emergency.
(b) Refuses to declare an emergency and you have determined the exact nature of the radar services the
If the aircraft has already encountered IFR conditions, inform the pilot of the appropriate terrain/obstacle
clearance minimum altitude. If the aircraft is below appropriate terrain/obstacle clearance minimum altitude
and sufficiently accurate position information has been received or radar identification is established,
furnish a heading or radial on which to climb to reach appropriate terrain/obstacle clearance minimum
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.
