The Impacts Of Advanced Avionics On Degraded Visual Environments, Sultan Naseeb Harib Fairouz Mubarak, Anju Anna Jacob Dr

International Journal of Aviation, Aeronautics, and Aerospace

Degraded visual environments (DVE) such as brownout, sand storms, and night conditions are responsible for accidents and hence losses in the aviation industry. There is a need to develop avionic systems to support pilots when they encounter environmental conditions that compromise their visual capacity. This report discusses the effects of DVEs on aviation, expounds on the advanced avionic systems available and further elaborates how these systems are implemented in countering DVE conditions. The report recommends on how advanced avionics systems have been and are being implemented in aircrafts to support decisions made by pilots flying under degraded visual environments.

Accuracy Assessment Of The Ebee Using Rtk And Ppk Corrections Methods As A Function Of Distance To A Gnss Base Station, Joseph Cerreta, David Thirtyacre, Peter Miller, Scott S. Burgess, William J. Austin

International Journal of Aviation, Aeronautics, and Aerospace

The use of unmanned aircraft systems to collect data for photogrammetry models has grown significantly in recent years. The accuracy of a photogrammetric model can depend on image georeferencing. The distance from a reference base station can affect the accuracy of the results. Positioning corrections data relies on precise timing measurements of satellite signals. The signals travel through the Earth's atmosphere, which introduces errors due to ionospheric and tropospheric delays. The aim of this research was to examine the eBee X and its global GNSS accuracy by comparing the RTK and PPK methods at different base station distances in photogrammetry …

Conceptual Design Of Fuel Dumping System In Aircraft, Naveen M. Kumar Mr., Ravi A. Kannan Be., Magesh L Be., Praveen T. Kumar Be., Vijay K. Babu Me., Prashanth Radhakrishnan Be.

International Journal of Aviation, Aeronautics, and Aerospace

Airlines release the unburned jet fuel into the atmosphere to reduce the weight of aircraft before landing. Sometimes, aircraft reach a weight more than takeoff weight while departing from the airport. Therefore, the pilot follows the ATC comment to dump fuel into the atmosphere to reduce the aircraft's weight to avoid accidents. Due to fuel dumping, an airline faces fuel consumption, loss, and several diseases affect environmental pollutants, and living things. The total fuel consumption of commercial airlines worldwide in 2021 is 57 billion gallons. If jet fuel routinely hit the ground, it would pollute water and land and damage …

Small Unmanned Aircraft Systems Acoustic Analysis For Noninvasive Marine Mammal Response: An Exploratory Field Study, David Thirtyacre, Gennifer Brookshire, Sarah Callan, Brittany Arvizu, Patrick Sherman

International Journal of Aviation, Aeronautics, and Aerospace

As in countless other fields of human endeavor, small unmanned aircraft systems (sUAS) have the potential to benefit pinniped (Pinnipedia; e.g., Phocidae [seals], Otariidae [sea lions], and Odobenidae [walruses]) response efforts. The employment of sUAS could give responders a close-up look at animals in distress in order to determine their condition as well as develop a response strategy. However, unlike other subjects that are regularly inspected by sUAS (e.g., croplands and civil infrastructure) pinnipeds may respond to the distinctive sound generated by small, multirotor sUAS. This reaction may include retreating into the water en masse, which could put …

A Review Of Dji’S Mavic Pro Precision Landing Accuracy, Cody Yoakum, Joseph Cerreta

International Journal of Aviation, Aeronautics, and Aerospace

Precision landing has the potential to increase the accuracy of autonomous landings. Unique applications require specific landing performance; for example, wireless charging loses efficiency with a misalignment of 100mm. Unfortunately, there is no publicly available information for the DJI Mavic Pro’s landing specifications. This research investigated the ability of a Mavic Pro to land at a specified point accurately. The purpose of this research is to determine if precision landings are more accurate than non-precision autonomous landings and if the Mavic Pro is capable of applications such as wireless charging when using precision landings. A total of 128 (64 precision …

In-Flight Wingtip Folding: Inspiration From The Xb-70 Valkyrie, Gaétan X. Dussart, Mudassir Lone, Ciaran O'Rourke, Thomas Wilson

International Journal of Aviation, Aeronautics, and Aerospace

Wingip folding can be used to extend aircraft wingspan, allowing designers to take advantage of reduced induced drag whilst respecting ground operational limitations. Such devices can also be used in-flight for a variety of other benefits including load alleviation and flight control. The majority of in-flight folding research takes inspiration in past developments made on the XB-70 Valkyrie, which used the folding devices for stability and lift performance benefits. In this paper, the authors investigate the capabilities of the folding wingtip system and potential scaling to large civil aircraft. Manufacturing details are used to size the actuators whilst the aerodynamic …

Comparison Of Fixed-Wing Unmanned Aircraft Systems (Uas) For Agriculture Monitoring, Joseph Cerreta, Kristine M. Kiernan

International Journal of Aviation, Aeronautics, and Aerospace

Florida citrus growers need inexpensive methods to observe citrus plants to detect disease and stress consistently. Health vegetation indices, such as the Normalized Difference Vegetation Index (NDVI) collected from Unmanned Aircraft Systems (UAS), can be used to identify variation in plant health. Simple-to-operate UAS may enable growers to determine within-field variation more frequently than with inspections from scouts, providing more frequent knowledge about the crop condition. This research compared two low-cost fixed-wing UAS, a $5,000 Parrot Disco Pro Ag and a $16,690 senseFly eBee, each equipped with a Parrot Sequoia multispectral camera, to determine if there were differences in the …

A Comparison Of The Strengths And Weaknesses Of Small-Format Aerial Photography Platforms, Jeremy W. Aber, Tyler A. Babb, Douglas E. Campbell, Kevin M. Corns

International Journal of Aviation, Aeronautics, and Aerospace

The demand for small-format aerial photography continues to grow in large part due to the rapid adoption of unmanned aerial vehicles (UAVs). Prior to the explosion of UAV use, this kind of photography was collected using older technologies such as tethered kites and blimps. Due to the increased demand for aerial imagery, this article looks at four platforms commonly used to collect small-format aerial imagery: multi-rotor UAVs, fixed-wing UAVs, kites, and blimps. Practical use considerations are explored, including characteristics of flight and operation, atmospheric and site factors, imaging sensors and costs, and regulatory limitations.

Each of the four categories of …

A Novel Approach For Missing Combat Support Aircraft Search Acceleration Using Vtol Uas, Mohammed Ba Zuhair, Wisam Yousef, Issam Samara, Vladislav Varsegov

International Journal of Aviation, Aeronautics, and Aerospace

In this paper, an approach to accelerate search operations for a missing combat support aircraft using a portable waterproof autonomous vertical takeoff and landing unmanned aerial system called “flying locator beacon” is described. The latter is connected with both flight data and cockpit voice recorders with a parallel bus and may be deployed from the empennage during extreme emergency scenarios, which is detected when few flight parameters are overrun leading to an air crash stimulating behavior. Landing of the flying locator beacon strictly takes place on global latitude and longitude coordinates only of integer values enabling significant minimization of search …
