Near the END of EACH runway, a symbol may be
present indicating Approach Lighting (ALSF-2,SSALR,SALS, etc.) or Visual
Glide Slope Indicator Lighting (VASI,PAPI). The symbols are listed in Flight
Information handbooks.
This particular Circled A with a 5
indicates Sequenced, Flashing MALSR (Medium Intensity Approach Lighting
System w/ runway alignment indicator system)
Because it is on the end of Rwy. 7 we
know that the approach end of Rwy. 7 has this type of lighting. Runway 25 does
NOT have any Approach lighting.
