If air traffic control or the meteorogical people tell you the wind is "270 at 6" this probably means the the wind is coming from a bearing of 270 at 6 units of Turn this to match the origin of the wind Conveniently it shows an arrow with feathered wind barb. You can work this with your fingers on the front. Set the wind direction using the double ended rotary scale. The scale tic marks shows individual degrees 0 to 359 deg. The scale number show the heading in units of 10ĭegrees. (0 = north, 9 = East, 18 = south and 27= west). Use the big nut on the back to rotate the entire top scale to set your aircraft heading. Use the screw at the bottom to set your airspeed using the scale along the handle.
AIR NAVIGATION COMPUTER PLUS
The front face of the gadget allows input of the aircraft heading, airspeed (through the air), plus the windspeed and the wind direction. This is manual, analogue, computer that adds the effect of the wind to the aircraft speed to tell you what direction is will be going and what speed, assuming the weather forecast is correct.Īlternatively if you can note what you have flown over and determine your track bearing from a map then you can work out the wind speed and its direction, as it has been affecting you. This isĪ navigational aid, primarily to help the pilot allow for wind strength and direction. There are similar devices for student pilots, see Wikipedia:įlight computer for a typical example flight computer. The old Japanese model I have, is illustrated below: This page is about a hand held Japanese aircraft slide rule flight navigation computer as used during the second world war by a Japanese pilot in Singapore. This framework of principles and procedures represents essential elements of management control and are the product of extensive analyses of management weaknesses.Views of the earth from geostationary orbitĮxplanation of antenna feed polarisation angleĭesign and draw your own satellite beam coverage In addition, GAO has developed a structured management approach for computer systems development. GAO believes the Government clearly needs a chartered, Federal computer service center to provide managers with managerial and technical system development expertise. GAO found that FAA has not implemented the parts of the planning and resources allocation order that apply to policy, mission analysis, long range planning, and program performance and evaluation. With better assurance of adequate equipment support, FAA can then adequately consider and plan the air traffic needs of the 1990's and beyond. GAO believes FAA should immediately initiate action to determine whether to buy a near term direct replacement system.
AIR NAVIGATION COMPUTER FULL
To make an adequate and informed decision regarding near term direct replacement, GAO believes FAA needs to identify the full cost and all implications of simply maintaining the current system in terms of operations, maintenance, and software.
GAO found that it is costing the Government more to continue using outmoded computers it now owns than it would cost to lease new, up-to-date computers. This schedule is inconsistent with Senate committee concerns and recommendations. The FAA reply projects a 3- to 4-year milestone schedule for near term computer system improvements and analysis of direct replacement of the current computer system. FAA was directed to report its actions on the recommendations to the appropriate committees by specific milestone dates. The Senate report contained recommendations to FAA. In its report, the Senate investigations staff found serious management and planning deficiencies in the en route air traffic control computer system. FAA officials had proposed acquiring a new $2.8 billion en route computer system sometime in the 1980's.
The comments were based on the extensive review conducted by the Senate investigations staff, the GAO analysis on the FAA reply to the Senate report, the GAO report on direct replacement of economically obsolescent and outmoded computers in the Federal Government, and lessons learned from GAO reviews of other large Government computer system acquisitions. Comments were presented on the Federal Aviation Administration's (FAA) Air Traffic Control Computer Modernization Program.
