Further experiments in progress at Tarrant Rushton are concerned with flight refuelling at night, an illuminated drogue being used as a guide to final engagement by the probe. A Mosquito is being used initially as the receiver aircraft, but it is understood that a Meteor will be substituted when the primary problems have been solved. In addition to its well-known activities in the development of air-to-air refuelling and radar equipment such as those I he transmitter; receiver and power units which comprise the described above, Flight Refuelling Ltd has recently received F.R.

The ground AR.B. approval for the facilities offered by its well-equipped power unit, on the left, is being re-designed to provide a workshops at Tarrant Rushton for the repair and maintenance lighter version for aircraft installation. of all types of commercial radio and radar equipment.
