Equipe Simulation Visualising Your Imagination Achieving FAA JAA

Equipe Simulation Visualising Your Imagination Achieving FAA / JAA Level D with current, low cost digital projection technology Contact: sales@equipe-simulation. com

Equipe Simulation Visualising Your Imagination Objectives • • To discuss the objectives of visual simulation To explain the need for Raster Calligraphic replacement To explain why this replacement is challenging To provide a summary of the competing technologies

Equipe Simulation Visualising Your Imagination Visual Fidelity • It ‘Feels’ inherently right that the higher the visual fidelity (resolution etc), the higher the pilot training value • Where do we draw the line in terms of cost / performance ? • The FAA / JAA criteria provide the metric which must be adhered to • Exceeding these criteria is possible but expensive • What is the Actual value of doing so ?

Equipe Simulation Visualising Your Imagination JAA / FAA Standards • Specifically focus on the requirements for • Visual Characteristics – ACJ STD 1 A. 030 2. 3… • Touch upon the requirements for • Latency - ACJ STD 1 A. 030 2. 1. r (2)

Equipe Simulation Visualising Your Imagination Visual Characteristics • Specific requirements • Field of View: • Resolution: • Light point size: • Surface contrast: • Brightness: • Light point contrast: • Total light points: 1800 x 400 Collimated 2 Arc-minutes 5: 1 6 foot-lamberts 10: 1 (day) 25: 1 (night) 6000 (day – 60 Hz) 15000 (night – 40 Hz)

Equipe Simulation Visualising Your Imagination Visual Characteristics • In the vast majority of existing Level C / D simulators, these criteria are met by Raster / Calligraphic CRT projectors • Operationally unique • High intensity ‘Calligraphic’ light points

Equipe Simulation Visualising Your Imagination Calligraphic Light Points What’s the big deal ? – Highly intense light points !! 1 frame (16 ms at 60 Hz) Raster complete, before next scan light points are drawn. Scan is continuous, each pixel is illuminated for an equal amount of time (10 ns at 1280 – 1024) Since only 2000 light points are drawn (at 60 hz), each point may be focused on for an extended period allowing for very high point intensity

Equipe Simulation Visualising Your Imagination Light Point Generation Light point generation is problematic, due to fundamental differences in the projection devices. • Light points drawn calligraphically in CRT projection • Competing technology is ‘Raster’ only This clearly results in the need to draw light points within the raster itself for non CRT based projectors.

Equipe Simulation Visualising Your Imagination Why Replace CRT’s ? The desire to move away from Raster Calligraphic CRT projectors is largely cost driven • High initial cost • CRT Tube lifespan • Require highly skilled maintenance • Require hundreds of hours PA on maintenance & alignment But also. . • Obsolescence concerns • Prone to expensive failure • Very heavy – potential logistical problems

Equipe Simulation Visualising Your Imagination What’s Required ? In order to match CRT in terms of level D criteria, the projector must • Have a high resolution • Produce an ‘Artefact’ free image • Have uniform colour between projectors • Be able to produce light points within the raster • Very high brightness • Very high contrast

Equipe Simulation Visualising Your Imagination About Resolution • The Level D Criteria specify 2 Arc Minutes per pixel • Therefore 30 pixels per degree • For a 180 x 40 display, 3 channels are an ideal • 180 degrees ÷ 3 channels = 60 degrees per channel • 30 pixels x 60 = 1800 pixels wide • 30 pixels x 40 = 1200 pixels high Therefore we can see that to achieve Level D in 3 projectors we need a resolution of at least 1800 x 1200

Equipe Simulation Visualising Your Imagination Alternative Technologies Light Valve projectors • LCD Liquid Crystal Display • LCo. S Liquid Crystal on Silicon • DLP Digital Light Processor Others… • Laser • Emerging, developmental technology.

Equipe Simulation Visualising Your Imagination Laser • Emerging technology • Potential for extremely high resolution • Potential for extremely high brightness and contrast • More efficient use of power • Very high cost • Prone to ‘Speckling’ and other artefacts • Unproven in the field

Equipe Simulation Visualising Your Imagination LCo. S Image is produced by passing light through an LCD substrate, and reflecting it from an underlying mirror Typically utilise 3 LCo. S panels to produce colour

Equipe Simulation Visualising Your Imagination LCo. S A relatively young technology • Reflective technology • Very High Resolution – up to native QXGA (2048 x 1536) • High Brightness • Potentially High Contrast – in high end units • No Frame Delay • Requires analogue control over LCD substrate • Complex • High Cost

Equipe Simulation Visualising Your Imagination DLP (single chip) Image is produced by an array of ‘Micro Mirrors’, one for each pixel. Colour is created via a rotating colour wheel

Equipe Simulation Visualising Your Imagination DLP A highly mature technology • Reflective technology • High Resolution – up to native 1080 p and beyond…. . • High Brightness • High Contrast • Low Cost • Pure, digital technology • ‘Rainbow’ effect caused by colour wheel now countered • 1 frame delay (16 ms at 60 hz)

Equipe Simulation Visualising Your Imagination Latency ACJ STD 1 A. 030 2. 1. r (2) specifies an over all latency of 150 ms Specifically the time between a Pilot control input and the Simulator responding – both visual and motion Motion base must respond before the visual therefore some latency is desirable !! 1 Frame delay introduced by DLP (16 ms) is in no way problematic In fact is equivalent to Raster Calligraphic projectors, since these ‘Scan’ 1 pixel at a time giving a 1 frame ‘delay’ between pilot Input and display of a Complete frame…

Equipe Simulation Visualising Your Imagination DLP vs. LCo. S offers • Very high resolution and potentially very high contrast DLP offers • Very high resolution and high contrast Both LCo. S and DLP offer resolutions high enough to meet the Level D surface resolution requirement (2 arc minutes per pixel), and both offer contrast ratios that potentially enable the generation of compliant light points, directly within the raster.

Equipe Simulation Visualising Your Imagination Cost Benefits With Civil airlines under increasing economic pressure, the underpinning goal should be to provide compliant systems at the lowest price point. While both LCo. S and DLP are able to meet the Level D criteria, DLP is a more mature technology that offers significant cost benefits

Equipe Simulation Visualising Your Imagination Level D with DLP Equipe Simulation has successfully designed and installed a number of Collimated DLP systems, both military and civil, compliant with both JAA and FAA Level D criteria. In these systems the use of DLP has enabled a cost reduction of up to 50% compared to competing technologies.
