This report describes tests conducted on two commercially available very high frequency (VHF) multicouplers to determine if they could meet a set of proposed specifications. The multicouplers met all proposed specifications except the intermodulation distortion requirements.
Microwave Landing System (MLS) Flare subsystem performance data were collected on a specially instrumented Federal Aviation Administration (FAA) Technical Center aircraft. The airborne data were compared with a theodolite tracking system reference and error plots generated. Due to extensive 1ightning damage only two flight tests were performed. Fla

A collection of available Microwave Landing System (MLS) literature is presented, as a result of searches conducted by computer through files of the National Technical Information Service, (NTIS), the Engineering Index (TM), and the INSPEC database, produced by IEE.
Preliminary flight-check procedures and system tolerances for the Microwave Landing System (MLS) are presented. A data-collection and recording package for use in light-aircraft measurement of MLS parameters in support of the System Test and Evaluation Program (STEP) is included containing a ground reference system, digital telemetry link airborne

Many industries, such as the aerospace and the automotive industries have successfully used Fiber Reinforced Polymer Composites (FRPC). These types of composite materials offer significant advantages over conventional civil engineering materials, such as concrete and steel. This is due to their chemical and corrosion resistance, lightweight, and hi
