A multi-function probe system that provides redundancy for measurements and compensates for effects of sideslip of an aircraft includes at least two probes that are symmetrically located on the opposite sides of the aircraft, and a third probe mounted on the centerline of the aircraft positioned to directly measure local sideslip with ports that are positioned on opposite sides of the center plane of the aircraft. Each of the probes includes self contained instrumentation for providing signals indicating various pressures. The local angle of sideslip sensed by the third probe is used as a compensation for pressure readings at either of the other probes for determining actual angle of attack, and static pressure.

A cable lock according to claim 14, wherein said means in said housing further includes key operated cam means for reciprocating and pivoting said clamping member. 16. A cable lock according to claim 15, further comprising means biasing said clamping member laterally away from said passageway. 17. A cable lock according to claim 16, wherein said cable clamping member has first and second clamping positions relative to said free end of said cable for respectively enabling said displacement in said first direction and in said second direction, and detent means for releasably holding said clamping member in each of said first and second clamping positions thereof. 18. A cable lock comprising a housing, a flexible cable having a first end anchored to said housing and having a free end, a cable passageway through said housing having opposite ends for selectively receiving said free end of said cable, a cable clamping member supported in said housing for displacement between first, second, and third positions relative to said free end of said cable in said cable passageway and in which positions said free end is respectively displaceable only in a first direction from one of said opposite ends to the other wherein the cable is held by the cable clamping member displaceable only in a second direction from the other of
