Landing gear is one of the critical subsystems of an aircraft. The need to design landing gear with minimum weight, minimum volume, high performance, improved life, and reduced life cycle cost have posed many challenges to landing gear designers and practitioners. Further, it is essential to reduce the landing gear design and development cycle time while meeting all the regulatory and safety re...

This paper presents a short contribution in air transportation, specifically in scheduling aircraft (plane) landings at Léopol Sédar Senghor (LSS) airport of Dakar. The safety of air navigation of LSS is managed by ASECNA: Agency for Air Navigation Safety in Africa and Madagascar. Scheduling aircraft landing is the problem of deciding a landing time on an appropriate runway for each aircraft in...

The growth of aviation traffic volume and the attempts to increase operational capacity by reducing aircraft spacing make aviation safety an urgent research issue in the aviation community. Simultaneous runway occupancy of landing aircraft is a precursor of a runway collision, and it is an effective of measure of runway landing safety. This paper presents an analytical method to evaluate the pr...

Autonomous contingency management systems, such as a forced landing system which reacts appropriately to an engine failure is important for the safe operation of Unmanned Aircraft Systems (UAS). This paper details a method to ascertain the reachability of any possible emergency landing site for a forced landing in steady uniform wind conditions. With knowledge of the aircraft’s state, such as s...

Parkour is an activity that encompasses methods of jumping, climbing and vaulting. With landing being a pertinent part of this practise, Parkour participants (traceurs) have devised their own habitual landing strategies, which are suggested to be a safer and more effective style of landing. The purpose of this study was to compare the habitual landing strategies of traceurs and recreationally t...

OBJECTIVE This study provides an experimental and finite element analysis of knee-joint structure during extended-knee landing based on the extracted impact force, and it numerically identifies the contact pressure, stress distribution and possibility of bone-to-bone contact when a subject lands from a safe height. METHODS The impact time and loads were measured via inverse dynamic analysis o...

The atmospheric disturbances affect not only flying qualities of an airplane but also flight safety. According to flight records, most aircraft accidents occurred during final approach or landing. If the flight conditions are beyond the preset envelope, the automatic landing system (ALS) is disabled and the pilot takes over. An inexperienced pilot may not be able to guide the aircraft to a safe...

To ensure the operation safety of landing signal officer (LSO) to pilot during carrierbased aircraft landing, the paper proposed a “LSO-pilot-aircraft” instruction associated with operation system. LSO guide mission, and design instruction associated with operation element is been analysed. The relationship and matching of “LSO-pilotaircraft” system are exhibited by instruction associated with ...

This paper presents an assertional-style verification of the aircraft landing protocol of NASA’s SATS (Small Aircraft Transportation System) concept [1] using the I/O automata framework and the PVS theorem prover. We reconstructed the mathematical model of the landing protocol presented in [2] as an I/O automaton. In addition, we translated the I/O automaton into a corresponding PVS specificati...

Integrated Vehicle Health Management (IVHM) is one of the few technologies that will help in reducing both maintenance and operational costs, while improving the overall safety of an aircraft. It also helps in moving away from conservative design philosophies. Hence IVHM is increasingly being adopted in various aircraft programs. IVHM requires a multi-disciplinary approach bringing together the...
