In busy airports, too many departing flights take off out of the time slot required by the Central Flow Management Unit (CFMU). During ground traffic peaks, taxi out times and runway queuing delays increase, and it seems very hard and maybe unfeasible for ground controllers to organise properly the traffic so that aircraft take off at their scheduled time. In a first part, this paper shows how ...

Knowledge of the fuel flow rate is important for accurate fuel burn and emissions inventory generation and for accurate engine performance modeling. In this paper, machine learning techniques are applied to aircraft flight recorder data to model the fuel flow rate as a function of the aircraft altitude, ground speed, vertical speed, and takeoff mass in the airborne phases of flight. Models are ...

In this paper, we discuss how the neighbors affect the decision of consumer behavior over diffusion of innovation. We suggest an agent-based model of diffusion and showed that on an online social network which have both of ”scale-free” and ”small world” properties, 1) the informative effect can cause a takeoff, but it is not sufficient to reach the completion of diffusion. 2) Meanwhile, the com...

1 INTRODUCTION Micro Aerial Vehicles (MAV) form a comparably new area of aeronautical research. This type of aircraft is defined by takeoff weights typically less than 500 g and very small dimensions, e.g. wingspans under 50 cm. Intense research is conducted worldwide to further reduce MAV mass and size (e.g. Within this paper, this term is expanded to also include so-called miniature unmanned ...

— Vortices can be produced and ingested into the intake of a jet engine during high power operation in the vicinity of solid surfaces causing Foreign Object Damage (FOD) or compressor stall and engine surge problems. This can occur when the engine is mounted on the wing of a plane during takeoff and engine ground runs or when the engine is placed inside a test cell for testing after an engine o...

A complete set of filters Fn for the optimal-depth n-input sorting network problem is such that if there exists an n-input sorting network of depth d then there exists one of the form C ⊕ C′ for some C ∈ Fn. Previous work on the topic presents a method for finding complete set of filters Rn,1 and Rn,2 that consists only of networks of depths one and two respectively, whose outputs are minimal a...

Nomenclature (contlnued) The paper discusses the development and testing of a real-time Takeoff Performance M Pitching moment (ft_lb) Monitoring System. The algorithm is madeup of two MACH Mach number segments: a pretakeoff segment and a real_time p Roll Rate (rad/sec) segment, q Pitch Rate (rad/sec) One_time inputs of ambient conditions and r Yaw Rate (rad/sec) airplane configuration informati...
