Stabilized Glide Slope Indicator System (SGSI)

Designed for air capable and amphibious assault ships, the SGSI system is an innovative electro-hydraulic-optical landing aid which allows pilots to visually establish and maintain the proper glide slope for a safer landing.  The SGSI system is an essential part to ensuring the protection of assault ships and cargo.

Equipped with green, amber, and red lights, the SGSI system provides an easy-to-read indicator of the glide slope.  A single bar lights up as green when the aircraft is above the correct glide slope, red when below, and amber when at the perfect glide slope.  The pilot is able to maintain the correct glide path to the ship’s landing pad by varying the aircraft altitude in order to maintain the amber light.  In order to stabilize the glide slope, a light cell is mounted on an electro-hydraulic stabilized platform, moving the platform in an opposite direction to the ship’s pitch and roll axes. 

The SGSI system takes further precautionary action by providing a failure detection circuit, which reduces platform dynamic errors.  The error detection circuits shuts off the GSI light in the event of a system failure, resulting in a GSI light source presentation.  Working as a preventative measure, the SGSI system combats possible glide slope errors.

Features: 
  • Prevention of incorrect glide slope
  • Automated, and easy-to-read lighting system
  • Reduction of platform dynamic errors through the failure detection circuit
Benefits: 
  • In high stress circumstances, pilots can take comfort in the single bar of light which carefully instructs them on how to land safely in aquatic situations
  • The SGSI seduces the amount work required of pilots to ensure a precise landing, and enables them to focus on the other factors involved in landing a plane
  • By proving its reliability and durability in complicated situations, the SGSI promotes a sense of security for pilots and passengers
Specifications: 

The size and weight for each assembly of the SGSI system are available upon request.

The assemblies that comprise the SGSI system together with their unit numbers are as follows:

  • Electronics enclosure assembly (F100).
  • Remote control panel assembly (F200).
  • Hydraulic pump assemble (F300)
  • Transformer enclosure assembly (F400) 
  • Glide slope Indicator assembly (F500) 
  • Stabilized Platform Assembly (F600)
  • Isolation Transformer Assembly (F900)

The amplitude and frequency of each of the following power sources, which the SGSI system requires to operate, must be regulated to within 5% of the requirements:

  • One 115 volt, 60 Hz, single phase, 10 ampere ships emergency power source (Automatic Bus Transfer) under grounded. Nominal draw is 8.5 amperes.
  • One 440 volts, 60 Hz, 3 phase, 5 ampere ships emergency power source (Automatic Bus Transfer) ungrounded. Pump draws 2.7 amps when running.
