Notes:

Development of a hub-and-spoke network increases the importance of keeping an airline's home runways open. Rather than wait for the US Federal Aviation Administration to upgrade the landing aids at airports, airlines in the USA in the early 90’s began to look at what could be done to their aircraft to enable them to land in low visibility.
The most promising solution appeared to be a system to enhance the pilot's ability to see the runway in fog. An enhanced vision system (EVS) comprises a head-up display
(HUD) onto which is projected an image of the runway from an infra-red (IR) sensor or
millimetre-wave (MMW) radar. The enhanced image allows the pilot to recognise the runway from a greater distance and to continue the approach, rather than divert.
Installation of a HUD in the cockpit overhead area was generally preferred. Overhead Projection Units were developed by the Company and in 1992 a HUD was test flown at the Maryland Advanced Development Laboratory on their Gulfstream II testbed aircraft. C0054. This is an overhead Projection Unit from an early design known as the Maryland HUD.
This is a space model of an Overhead HUD with an integral Combiner very similar to the Maryland HUD.
