visibility Seis off Goa radio drama Pilot Blank this is air Force request ground controlled r Oca air Force this is Blank what is your heading and estimated ceiling 300 visibility one wind seat six Miles per Pilot Blank this is Altitude heading 350 estimated eight Miles Southeast of Blank Goa this is Blank we have you in our pick up a heading of 345 degrees and letdown to Pilot Blank this is letting Down to feet and turning to heading of 345 you Are five Miles South of Blank continue to maintain feet Altitude and pick up a heading of 180 2938 maintaining feet and steering to 180 Goa 2938 from Blank maintain present heading and if at any time you lose Contact with Blank Goa j for More than three make a 180 degree turn and Call Blank acknowledge All instructions from Vuot 2938 to Blank

Pilot Roger this is 2938 steering right to 085 a 2938 from Blank steer left to a heading of 350 Pilot Roger this is 2938 steering left to a heading of 350 2938 you Are approximately 8 Miles Southeast of Blank Field on base leg for this is 2938 5 of Goa 2938 from Blank steer left to 260 degrees and git Start a Normal rate of 9 Roger this is steering left to 260 degrees us and beginning Normal descent c Goa 2938 from Blank this is the you Are in sigh approximately seven Miles from the end do not reset your gyre your gears should be Down and use flaps at your own do not acknowledge any you Are slightly to the rights steer left 256 your rate of descent is too you Are slightly below the Glide is heading and rate of descent Are Okay maintain 256 degrees and present rate of now steer right to 258 you Are on the Glide five Miles from final steer left 256 two Miles from end of holding on Glide path one mile end of now steer right 259 you Are slightly above the Glide increase rate of descent you Are on Glide heading is one Quarter mile from end of runway be dead ahead and you Are on Glide you Are now Over of runway and at 50 take Over Blank Oca out Ilot swell thanks a pilots talked Down 5 Safe Fields equipped with radar Landing units March 23 sheep dogs we find them and Shepherd them that Ishow the 5th airways and air communications service Wing explains its technique of ground control approach Goa which talked More than pilots landings in Germany and Austria during More than of the landings were letdown made under instrument conditions in weather ranging from a 500foot ceiling and three Miles visibility Down to a 200foot ceiling and a one Quarter mile at air farces in Europe installations in Berlin and the men behind the controls of the Goa equipment daily perform a series of minor miracles guarding the lives pilots and millions of dollars Worth of aircraft and equipment when the weather is socked in at the five Goa equipped Safe the almost human presence of Goa enters the it works of the following two radar beams Are employed to sweep the air space inline with the runway for a distance of 10 one gathering data on the of the Landing the other collecting information on the direction of its a radar search system covers the area within a 30 mile radius from the the planes position is registered on a screen in a ground Mobile unit where a radar operator studies the data and advises the Pilot by radio How to Man Euver his plane for a Safe its simplicity of operation and excellent safety Goa is very popular with although Goa was first put into operation the last phase of world War is credited with than under combat conditions a Goa is the brain child Luis Alvarez an air minded scientist engaged in to secret experiments in the National defense research councils radiation Laboratory at Massachusetts Institute of technology just prior to the beginning of world War radar and electronic devices like Goa Are slowly but surely making Al weather flying a six trained men constitute Crew a Goa unit requires a Crew four controllers and two the traffic director at the one position is responsible forthe initial identification and direction of the aircraft preparing to number two Man is the plane he takes Over from the traffic director and gives the Pilot preliminary primarily his Job is to Man Euver the Craft until it appears on the Eleva Tion trackers indicator Scopes in suitable position to the number three Man is the final approach controller who is in the entire Goa operating he takes care of azimuth and Elevation and keeps the Pilot informed As to the distance from his Landing his direction of fending and the number of degrees of to the left or right of the Center line of the he interprets All the scope and meter readings and gives the Pilot final Landing instructions Over the radio number four Man on the Goa Teantis the Eleva flon tracker who keeps constant track of the aircraft Winston of operate 1 ing the azimuth tracker on the Furstenfeld Bruck air base Goa takes a Reading on the device which keeps track of aircraft in to the i t Elevation which is indicated to the final approach on his the two skilled Goa radar and radio mechanics stand by ready to repair any possible mechanical failure in the set on a moments the Goa units Are in full operation 18 hours a day1 and during the of hours they Are kept on a 20minute Alert basis for emergency x at present Rhine main air base maintains three full qualified Crews to handle Goa traffic for air Force planes and the planes of eight commercial air Ever since a French plane crashed last year Wale attempting to land because of the language Barrier Between the French Pilot and the american Goa and English speaking Are maintained at Rhine main at All French and English have since been designated As the official Goa languages for pilots of the com Mercial airlines which use Rhine am 1 further improvements forecast the Goa system has reduced Landing hazards while increasing the number of flights which can be cleared in and out of the american zone during poor As a Means of familiarizing of pilots Safe recently ordered Allaf pilots in the dec to make a minimum of five Goa practice approaches during training it is hoped to improve Goa still further by trans Ferring Goa radar units from Mobile trucks and trailers parked near the end of the runways of scanning Scopes placed in regular traffic control towers Over the an installation would enable a relatively Small Force of operators to see All planes within a 30mileradius on one scope and observe their exact Landing approach path on another More precise i exterior of a ground control approach unit is shown truck at right is the Power search antennae at each end of the unit Send oat
