Jay, I think you are referring to the drop check of the hydraulic reservoirs. The reservoir was depressurized and then repressurized at which time you would observe the amount of drop that ocurred in the sight gage. If the drop was excessive (3/4 inch I think) it indicated that air was entrapped in the hydraulic system and sytem bleed was required. The F-106 was very sensitive to air in the hydraulic system. Hope this helps.

The "Old Drop Check" was used extensively by the "Early MA-1" troops! This was later modified to the "Hard LAnding Check" The principle MA-1 system boxes involved were mostly the old Mark-7 Computer units! All 30 + of them! The only one I personally didn't try this on was the Computer Drum! That would have been a real catastrophy! Most of the older computer units had rows of cards inside with vacuum tube flip-flops and switches that tended to stick together at the contacts. This action was realatively an easy fix to get them to release. The best solution was later when the computer was upgraded to the HCM-204 , from Hughes. It was ALL solid state, and had a LOT less units to contend with. and certainly more reliable! Thats the definition of a DROP CHECK to the MA-1 world! MArv
