The LAF Runway 10 PAPI has a non-standard 'Slightly Low' indication; which is defined in AIM Figure 2-1-5. The slightly low indication should be a sequence of four lights colored WHITE; RED; RED; RED in that order. The LAF Runway 10 PAPI 'Slightly Low' indication is RED; WHITE; RED; RED. I've already reported this to the ATCT once about 10 days ago; but no action appears to have been taken. Tonight; while inbound to this runway; both my student and I observed the indication.
An instructor pilot on approach to LAF Runway 10 noted the PAPI indication for slightly low was RED; WHITE; RED; RED but according to the FAA AIM should be WHITE; RED; RED; RED.
