Abstract: A method of detecting the presence of insects, including larvae, in an indoor environment, which includes the steps of (a) obtaining a sample of volatile organic compounds (VOCs); (b) separating the sampled VOCs; (c) detecting the presence or absence of “target” VOCs from at least one category: “category 1 VOCs”—VOCs emitted independently of the support on which the insects develop and emitted only in an insect infestation VOCs, “category 2 VOCs”—VOCs emitted independently of the support but may have biological origins other than insects, and “category 3 VOCs”—VOCs emitted depending on the support and emitted only in an insect infestation; (d) calculating both an insect infestation index (“3I”) and a limit value (“VL”) based on the presence or absence of the target VOCs; and (e) comparing the “3I” and “VL” values. The environment is infested for a “3I” value strictly greater than the “VL” value.

Abstract: A method for verifying coherence of takeoff parameters of an aircraft from an airport with an available runway length at a moment of takeoff comprises a step of identifying a takeoff runway and a step of validating takeoff parameters with a view to authorizing takeoff of the aircraft if the takeoff distance is shorter than the remaining runway length associated with the identified takeoff runway.

Abstract: The inventive flight control assisting device comprises first means (4) for determining the actual aircraft flight conditions, second means (5) for determining, with the aid of said actual flight conditions and a predetermined pattern, a minimum approaching distance corresponding to a minimum distance between projections on the horizontal plane of the aircraft actual position and a touch-down point when said aircraft moves downwards and decelerates according to an optimised approach in such a way that stabilised approaching conditions are attained, and display means (7) for displaying at least said minimum approaching distance on a navigation screen (9) in the form of a first circular arc focused on a position relative to the aircraft which displays the touch-down position.

Abstract: An altitude profile representative of the terrain overflown by an aircraft is established. Thereafter, an altitude limit curve which comprises an intersection with the altitude profile upon the engagement of a terrain avoidance maneuver is determined. As soon as there is no longer any intersection of the limit curve with the altitude profile, the terrain avoidance maneuver is interrupted.

Abstract: An aircraft guidance and piloting system automatically guides and pilots an aircraft in the event a pilot is unable to guide or pilot the aircraft. Upon determining the pilot's inability to control the aircraft, a processor transmits an automatic engagement command to a control unit. The control unit guides and pilots the aircraft to an alternative airport for landing.

Abstract: A system for aiding the piloting of an aircraft during a runway approach includes an information source that provides information relating to the aircraft and its environment. A computation unit determines, with the aid of information provided by the information source, an energy reference profile having a trajectory reference profile and a speed reference profile that allows the aircraft to regain a stabilized approach trajectory, if it follows the reference profile. A monitor verifies that the aircraft is following the reference profile. An indicator supplies the pilot with piloting indications for piloting the aircraft so as to follow the reference profile.
