`Digitisation is doing for avionics
`
`computing system with high redundancy
`which will manage all the aircraft's flight
`control and management needs.
`
`In the following tables the size of some
`avionics-rack equipment is presented in
`manufacturers' standard unit terms. As
`digitisation makes units smaller,
`the
`ARINC "form-fitter" MCU
`(modular
`concept unit) is superceding the ATR
`(air transport radio) rating. 1 MCU
`corresponds approximately to 1/8 ATR.
`
`what it is doing for all forms of
`data processing. It is making
`avionics faster, more accurate,
`compact, reliable and enabling tasks to be
`carried out which would have been
`impossible — or at least not practical —
`before its advent.
`There is another development becoming
`progressively clearer in the avionics field:
`integration of the computing capacity for
`multiple tasks, and also progressive inte(cid:173)
`gration also of displayed information.
`
`COMPILED BY MICHAEL PAYNE
`Obviously sensors will remain independ(cid:173)
`ent with specific designated
`roles as
`suppliers of the base data on which the
`computers work, but a single high-capacity
`computer could now receive all sensor-
`supplied data, sort it, address it, and send
`it
`to cockpit display or control unit
`destination.
`Stand-alone avionic units are still widely
`available, but

`WEATHER RADAR
`Commercial weather radar has benefited enormously from the technical advance of military airborne
`radar funded by defence budgets. Intense precipitation, which indicates turbulence, can be detected
`at considerable distances, so that pilots can plan deviations. Digital signal-processing — including
`doppler processing" for detecting turbulence — and multi-colour displays provide civil aircrew with
`facilities as effective for their purpose as those combat crews have.

`All major Western aircraft makers use high-brightness, high-resolution, full-colour Cathode Ray

`to read; display formats far more informative than is possible with conventional instruments and
`improvements can be devised, developed and implemented relatively easily; and as far as is necessary,
`any format available on a flight deck can be called up on any screen. Disadvantages are the
`considerable bulk of a CRT and its heat output, which requires fan cooling. Both snags should be
`absent in the next-generation displays, which will be based on matrixes of pin-point, coloured, liquid

`GROUND PROXIMITY WARNING SYSTEMS AND WINDSHEAR WARNERS
`GPWS were invented about 15 years ago, after several aircraft had crashed because pilots did not
`know that they were too close to the ground. A unit takes radar altimeter and air data inputs and
`gives voice warnings if the rate of descent or closure to the ground is excessive, if the absolute
`ground clearance is too little, and if height is lost after take-off. Some units are integral with
`windshear warners. Windshear is a sudden change in windspeed or direction which tends first to
`increase and then suddenly to reduce airspeed to a dangerous level. It can be fatal if an aircraft is
`near the ground unless the pilot recognises the nature of the situation and takes appropriate action.
`Warners detect windshear effects on an aircraft, sound a warning and direct recovery action.

`FUEL MEASUREMENT SYSTEMS
`Safety and economics demand accurate measurement of the amount of fuel in the tanks at all times.
`Aircraft attitude and motion, along with the odd shapes of many tanks, make measurement
`technically complex. Tanks have numerous probes rising from the bottom surface, the fuel level
`around each is detected and the results integrated. Conventionally, a probe's changing electrical
`capacitance with changing fuel level is the detection principle.

`
`TRAFFIC ALERT AND COLLISION AVOIDANCE SYSTEMS AND MODE S TRANSPONDERS
`TCAS are intended to minimise the risk of a mid-air collision in increasingly crowded skies. The
`unit interrogates the SSR transponders in nearby aircraft, notes their absolute and changing altitudes
`and indicates their bearings. It indicates the required evasive manoeuvre if a collision with a nearby
`aircraft appears imminent. Wholly effective use presumes universal fit of Mode S transponders, which
`have a data link enabling closing aircraft to communicate to reconcile their manoeuvres.
