The Landing Signal Officer (LSO) Trainer, developed through an austere yet comprehensive research and development program at Vought, will provide another first in naval aviation training. It will provide simultaneous simulation training, with performance evaluations, for LSO's and pilots in a closed-loop mode. LSO on-the-job training requirements for the control of actual aircraft are eased. JP-5, aircraft flight hours, aircraft maintenance, and time in the training of an LSO are direct savings. In an era of more restrictive budgets and reduced operations, the opportunities to teach and learn aircraft control are more limited. The Landing Signal Officer Trainer will increase the training opportunities and provide a closed-loop pilot/LSO training relationship.
