Show Wingovers All The News That's Fit To Print - From The Delta Airport. By Dick Morrison Take Offs and Landings T. A. (Andy) Bouck of Thompson Thomp-son Flying Service set -his Cessna 140 down here Sunday afternoon. Andy tells me he has put in a bid to operate the Ogden weld, and if 1 his bid is accepted he expects to! run it under the name of West American- Aviation. Robert Pool, Jr., of the Texan Joveiopmeni uo., landed nere bu-day bu-day in a Navion. Making tCie fight from Texas with him were Kimball 1 J'ohanse.n, Lloyd Jensen and L. W. 1 ensen. The party spent Sunday visiting with Mr. and Mrs. Ivan Sorenson in Sutherland. Computer Ccpsrs Given the three- sides of a triangle, tri-angle, how would you find the three angles Or if thats' too easy, take this one: Given two sides and angle not included between them, but angle adjacent to first side, find third side and other angles. Elementary? Then tr y a temperature tem-perature conversion problem. If it's 40 below zero C at. 20,000 ft, what would the Fahrenheit reding be? 40 below? Sure. Since you're so sure of that last answer, how about converting a few nautical miles to statute miles? Whether these problems are easy or not, Art Rose was reeling off answers like an electronic calculator cal-culator Sunday afternoon between weather observations. Art has a neat little computer known as Uil-. American A.i.ines Computer, Type C, designed fur pilots and navigators, complete with an in-sirueuon in-sirueuon book, . and it tells you just about everything about Hying Hy-ing problems. H consists oJ three revolving discs four inches in diameter, dia-meter, with all kinds of scales. It was compiled by the A. A. Engineering Engin-eering Depl: It solves problems involving such things as true airspeed, calibrated airspeed, groundspeed, distance, al titude, fuel consumption, rate of climb, wind angle, wind correction correc-tion angles, compass headings, course correction, wind direction and velocity, and triangles, both right and oblique. Art was just unbeatable Sunday as long as he had his computer handy. He knew all the answers. Here's a track and groundspeed problem that didn't even feaze him: Given true heading north, or 0, true airspeed 180 mph, wind 40 mph from due west or 270, find track and groundspeed. The discs of Art's computer fair-lyhummed, fair-lyhummed, and in a moment he came "up with track 12, GS 185. (Any wise guy that says this answer an-swer is obviosly haywire,' please remember this is a track and GS problem, not a true heading problem.) prob-lem.) "What- type plane, would be flying fly-ing at 180 AS?" I asked. "Oh, a DC-3," Art said. "I thought they were rated a-bout a-bout 160," said I. Even that didn't stop him. "If it were at 10,000 ft., the air temperature tem-perature could easily be zero centigrade, cen-tigrade, couldn't it?" he asked. It could, of course. So, with a few deft twists of the discs, Art correlated some more data, and brought forth the fact that with the DC-3 iat 10,000 ft., temperature 0 C, indicated airspeed air-speed 160 the actual AS would be 188. That settled that. So when you're flying the Aer-onca Aer-onca sedan and you call Delta radio and Art answers, and you tell him you are flying to Salt Lake and have just crossed above the Jericho road and want to know your groundspeed, you may expect ex-pect Art to have the answer on the tip of his tongue. Prize Problem Given TC, AS, GS, Wind velocity. Find TH and Wind direction. How? That's the question. When I first dreamed that one up, I thought of calling it the $64 question and offering a prize for the correct answer. On second thot, however, I decided that flying enthusiasts en-thusiasts would get just as much fun out of solving it without any cash priez, so I might as well keep the money. Hence, no offer of oash. Still, it is an intriguing problem. prob-lem. To give it a specific example: Assuming that a plane has an airspeed air-speed of 100 mph, and maintains a true course of45, or northeast, from what direction would a 35 mile wind have to be blowing to oause the plane to maintain a GS of 100 mph along the TC, and what would be the true heading? Now any lunkhead can get the answer by trial and error, by drawing draw-ing a few wind vectors; and some people like Art Rose might stumble stum-ble onto it with a computer. But the point is that the answer must be found by a systematic, direct method. The method itself is as important as the right answer. Stunt Flier Retires. A noted woman pilot and stunt flyer retired to home life recently after a thirty year aviation career. ca-reer. Her last position was consultant consul-tant with the CAA. She is Mrs. Phoebe Omlie. She began her flying fly-ing and acrobatic career at the age of 17, as Phoebe Fiairgraves, and she had played an important part in aviation ever since, as acrobat, ac-robat, racing pilot, and business executive. Her most sensational stunt was that of changing from one plane to another in the air. After a stint as the woman on the flying trapeze, tra-peze, she married her instructor, Vernon Omlie. I don't know what you think about this, but it strikes me that after she'd performed that stunt for him that was .about the least he could do for her give her his name. ' |
