24.5.1.4 Altitude/Flight Level (/FL)
The altitude/flight level (/FL) is the altitude in hundreds of feet MSL where the phenomenon was first encountered. If not known, UNKN is entered. If the aircraft was climbing or descending, the appropriate contraction (DURC or DURD) is entered in the remarks (/RM). If the condition was encountered within a layer, the altitude range is entered within the appropriate element that describes the condition.
Examples:
/FL085 8,500 ft MSL.
/FL310 Flight level 310.
/FLUNKN /RM DURC Flight level unknown, remarks, during climb.
