loool....sorry!
i hate these questions! Anyways, here's the answer i made up...which is prbbly what i'd do in the exam... dont u have the mark scheme? wat yr?

Computer-controlled Aeroplane Landing System

Input:Altitude,Runway length,present aeroplane speed, distance from destination,timings for other flights' landing, weather conditions, signals from ground station.
Process: Validates data received, decides weather weather is suitable for landing, calculates suitable runway speed,c0-ordinates landing time with other flights and decides if runway will be free, calculates time at which descent must start
Output: Opens wheels when close enuff to ground, automates descent process at appropraite time, turns on passenger safety signs ( seat belt, lavatory, etc.) in cabin at appropriate time,  sends signals to ground station, adjusts cabin temperatures/pressure for landing ?!?

looooooool.....dont laugh sarah!

i think, im not so sure
input: height of plane, speed, maybe air pressure,position of plane
processing: slow down plane, lower the height, give commands to open wheels, and apply brakes when landed ( to stop plane)
output: speed reduced, wheelss opened, plane lowers height and touches ground, brakes applied and therefore plan lands succesfully and stops
