A Holographic Head-Up Display for Low Visibility Landing Operations
A new system has been developed to meet the difficult requirements for aircraft operation in low visibility conditions. Unlike automatic systems, this system utilizes and enhances the pilots' flying ability through a holographic head-up display which provides bright, clear information across a wide field of view. The information presented is monitored to ensure probabilities of misleading the pilot to be on the order of one part in 10−8. The system is now undergoing verification tests in a B-727 turbo jet aircraft with the objective to obtain certification for use in CAT IIIa, 700 feet visibility conditions.
