Don't know anything about it in operational terms, but my tome of FMS info says that it is perf code dependent. In other words the code has to be selected on the perf maintenance page LSK1. It is effective, if the appropriate code is operative, until the first power reduction.
"LSK1 (The Perf code) displays the binary state of Perf Option Code program pins. Program pins aredisplayed in left to right order of MP15F, MP15E, MP15D and MP15K. Program pin status is only updated after a long term power interrupt while on the ground.".........What did Horace say, Winnie?
