A new, completely independent monitor (capable of operation through Category IIIc weather condition) for use with automatic landing systems, is undergoing development by Lockheed for possible use in L-1011 aircraft.
Following intensive analysis, a Ka band airborne radar was selected to provide pilot confidence through independent monitoring of the L-1011 (1) dual-dual, fail operative, automatic landing system's performance.
Lockheed's airborne flying test bed (CV-240) program has so far provided evidence that the Independent Landing Monitor concept has a definite future in commercial automatic landing applications under reduced visibilities. Visual enhancement would improve the acceptability of near zero-zero operation and consequently reduce the number of unnecessary go-arounds.
