Improved Fresnel Lens Optical Landing System (IFLOLS)

PDI Part Number: 3429AS8115-WC (-1), 3429AS8115-NC (-2)

The Improved Fresnel Lens Optical Landing System (IFLOLS) is an optical landing aid used aboard Naval Air Stations.  It is designed to give glide path information to pilots to help them land. The trailer is a TIG-welded, specialty manufactured variance of the MHU-141/M munitions trailer. It is used primarily by the Navy and Marines Corps. 

PDI has designed and manufactured two versions of this trailer - the "-WC" which includes a center support channel, and the "-NC" which does not include a support channel.

"Thank you PDI for your outstanding dedication, communication, commitment and "can-do" attitude. You were able to quickly respond to the Navy's requests to design and manufacture three completed IFLOLS trailers. We are proud of your exemplary efforts and your tireless support to our Command."

--US Navy, Naval Air Warfare Center
