There were several dysfunctional interactions and communication inadequacies among the correctly operating aircraft equipment. The most obvious unsafe interaction was the release of two missiles in the direction of two friendly aircraft, but there were also four obstacles to the type of fighter-helicopter communications that might have prevented that release. 

The SYMBAD s structure can be easily adjusted depending on the type of test equipment, eg. for unmanned air systems, helicopters and combat aircrafts. Moreover, programme modification can include type of research being conducted for a new-designed and -developed aircraft as well as for an upgraded one, for those in production, and for the aircraft equipment/systems built in the aircraft. 

The methacrylic polymer remains a useful glazing material. In aircraft applications it is used extensively on aircraft which fly at speeds less than Mach 1.0. They form the familar bubble body of many helicopters. On land, acrylic sheet is useful for coach roof lights, motor cycle windscreens and in do-it yourself cabins for tractors and earth-moving equipment. Injection mouldings are frequently used for plaques on the centre of steering wheels and on some fascia panelling. 

Dipping sonar devices equip manned antisubmarine helicopters and fixed-wing aircraft the aircraft flies low and suspends a sonar device at the end of a wire-link which is held just below the surface of the w. The sonar technique is also used in sonabuoys, which use active or passive sonar to detect and locate submarines. Sonabuoys provide anti-submarine warfare data to aircraft which cannot dip sonar devices while hovering overhead, the data being transmitted by coded radio signals... 

Application - this task involves driving a vehicle which either pulls the application equipment or where the equipment is contained within the vehicle itself. This would include trucks (with tank and mounted spray rig), tractors (which pull a tank and spray rig), other self-contained units and aircraft (helicopters or fixed-wing planes), which are equipped with tanks or hoppers and spray, dusting or granular application equipment. 

This major branch of the armed forces owns and operates a range of facilities and equipment. These include buildings, vehicles, trucks, aircraft, helicopters, missiles, and weapons storage facilities. Corrosion costs are a significant burden for the Army, including the cost of maintenance of weapons systems. 

The F-15 s were equipped with avionics, communications, and electronic equipment similar to that on the Black Hawks, except that the F-15 s were equipped with HAVE QUICK II (HQ-II) frequency-hopping radios while the helicopters were not. HQ-II defeated most enemy attempts to jam transmissions by changing frequencies many times per second. Although the F-15 pilots preferred to use the more advanced HQ technology, the F-15 radios were capable of communicating in a clear, non-HQ-II mode. The ACQ directed that F-15s use the non-HQ-II frequency when specified aircraft that were not HQ-II capable flew in the TAOR. Qne factor involved in the accident was that Black Hawk helicopters (UH-60s) were not on the list of non-HQ-II aircraft that must be contacted using a non-HQ-II mode. 

Even if they had been on the same frequency, the Air Force fighter aircraft were equipped with HAVE QUICK II (HQ-II) radios, while the Army helicopters were not. The only way the F-15 and Black Hawk pilots could have communicated would have been if the F-15 pilots switched to non-HQ mode. The procedures the pilots were given to follow did not tell them to do so. In fact, with respect to the two helicopters that were shot down, one contained an outdated version called HQ-I, which was not compatible with HQ-II. The other was equipped with HQ-II, but because not all of the Army helicopters supported HQ-II, CFAC refused to provide Army helicopter operations with the necessary cryptographic support required to synchronize their radios with the other QPC components. 

For the second expedition to Antarctica Byrd, once again, had two ships (Bear of Oakland and Jacob Ruppert) which arrived off the coast of Edward VII Land on December 20, 1933. After penetrating the pack ice, the ships entered the Bay of Whales on January 17, 1934 and unloaded their cargos including 150 sled dogs, four aircraft (including a helicopter), several tractors, three Guernsey cows, and a calf who were to provide fresh milk for 56 men. None of the land-based expeditions of Robert Scott, Ernest Shackleton, and Roald Amundsen was as well equipped or included so many men. Nevertheless, both of Byrd s expeditions relied on traditional as well as on modem means of transportation. 

One possible means of constmction is as follows A scouting aircraft (helicopter) confirms a satellite-surveyed ice field as suitable and delivers to it a small tractor with extensible wire-saw. The tractor saws up the ice platform to hew there from a platform of a specified size (including allowance for melting before insulation for example, 500 x 500 x 10 m) (Figs. 55.6 and 55.7a) and an ice-braker ship tows this platform to open water. Here the platform is equipped with air-film covers, protected by from warm water on all sides. The platform is towed to a place where it will be provided with final protection and other improvements a suitable location...
