Changing The Process In Educational Field And Air Navigation Through Advances In Hologram Technology, Camilo Fernandez Sr.

Journal of Aviation Technology and Engineering

The objective of this piece is to propose reasons that change the way air traffic controllers and others learn and work in air navigation, but also how they can improve workloads, due to the implementation of holographic radar. This research also aims to describe how this could reduce the cognitive load of an operator, thanks to the improvement of visual perspective and capacity of analysis, in order to more easily control an aircraft.

Seeing that the visual facilitation is well known, radar is able to represent in three dimensions and in detail that which could not previously be perceived. This …

Design Of Rotorcraft Performance-Based Navigation Routes And Procedures: Current Challenges And Prospects, Carlos Gonzaga Lopez

Journal of Aviation Technology and Engineering

Helicopters play a relevant role in society due to their extraordinary versatility. However, they are particularly vulnerable to adverse weather conditions as the majority of operations are carried out under visual flight rules. This is partly due to the shortage of tailored helicopter instrument flight procedures and routes. The emergence of the performance-based navigation concept supported by the latest satellite navigation technologies has opened up new possibilities for rotorcraft operations in the last few years. This paper presents an extensive overview of the state of the art in the design of performance-based navigation routes for helicopters from two main standpoints: …

Airplane Pitch Response To Rapid Configuration Change: Flight Test And Safety Assessment, Ralph Kimberlin, Markus Wilde, Brian Kish, Isaac Silver

Journal of Aviation Technology and Engineering

This paper examines airplane response to rapid flap extension on seven general aviation airplanes. The scenario involves a pilot flying in the traffic pattern becoming distracted, abruptly extending flaps while looking outside the airplane, and failing to notice airspeed and pitch-attitude changes. The airplanes tested reached pitch forces of up to 36 lbf, meeting FAA requirements but exceeding the capability of 55% of the population. Flight data showed a pitch-up to more than 30˚ in 5 s after flap extension, causing airspeed to drop below stall speed for four of the airplanes. At traffic pattern altitudes, stalling an airplane can …

Atmospheric Pressure Calibration To Improve Accuracy Of Transponder-Based Aircraft Operations Counting Technology, John H. Mott, Chuyang Yang, Darcy M. Bullock

Journal of Aviation Technology and Engineering

In the United States, over 2,400 of the 2,941 non-primary National Plan of Integrated Airport System airports have limited means of establishing operations counts due to lack of available personnel. Precise counts of airport operations are helpful for allocating airport improvement funds, as well as for local and system planning. An emerging technology utilizing ADS-B position data to calibrate signal strength received from Mode C transponders, thereby capturing location information from over 90% of the aircraft operating in the National Airspace System, has successfully estimated operations counts at these non-towered airports with reasonable levels of accuracy. This paper evaluates the …

Tooling Design Modeling For Composite Fuselage Of Beechcraft King Air 250 Using Catia, Miazor Fidelis Ekom

Journal of Aviation Technology and Engineering

Aircraft’s constant operation in tough conditions necessitates the need for structural components of high strength yet low weight. Composite materials are being used as an alternative to conventional aluminum alloys because of their competitive strength-to-weight and stiffness-to-weight ratios. In this paper, the detailed design procedure of a light-aircraft composite material fuselage tooling in three dimensions is shown. In its operation, the layup tools provide a surface for the composite part which is the correct shape of the part and is stable through the cure cycle, and also providing a means of indexing the part for the next manufacturing operation. This …
