ACR430 SPEED
The 430 did have two speeds , the faster one giving a faster update on the "blip" position. At Luton we didn't use it as I recall it had a serious effect on the scanner which you did not want failing . I thnk we even taped the switch in the slower position. As another aside about the same time that the 08 ILS was installed the radar head was badly damaged when it caught fire,( was it
suicide ?)
