WAS CONTACTED AND ADVISED A VOR RECEIVING DEVICE WOULD BE TOO
BULKY TO BE CARRIED ABOARD THE FLIGHT UNSEEN, AND DUE TO THE
TECHNICAL EFFORT OF THE DEVICE, IT WOULD PROBABLY REQUIRE A GOOD
DEAL OF TRAINING IN ORDER TO OPERATE IT. HE ADVISED THE
SMALLEST MODEL OF THE VOR RECEIVING DEVICE IS TWO POINT SIX INCHES
BY THREE POPNT TWO INCHES BY TEN POINT SEVEN IN LENGTH, WEIGHING
TWO POINT SEVEN POUNDS. SUCH A RECEIVER WOULD REQUIRE A TWELVE
VOLT BATTERY TO OPERATE PROPERLY, AND HORIZONTAL - POLURIZED
ANTENNA APPROXIMATELY THREE FEET IN LENGTH WHICH WOULD EITHER HAVE
TO BE EXTENDED FROM THE AIRPLANE OR ATTACHED TO THE WINDOW IN A
VERTICAL POSITPOM.
