摘要:
A display system for an aircraft includes a central unit configured to determine a speed vector of the aircraft and to determine a longitudinal margin of maneuver of the aircraft. The longitudinal margin of maneuver is expressed as a load factor and is related to one of a pitch-up maneuver and a pitch-down maneuver. The display system also includes a display unit connected to the central unit. The display unit includes a display screen configured to display a first characteristic sign illustrating the speed vector and a second characteristic sign illustrating the longitudinal margin of maneuver.

The device (1) for aiding piloting comprises means (2) for determining a speed vector of the aircraft, means of depiction (4) for presenting on a display screen (6) a first characteristic sign illustrating the speed vector of the aircraft, and auxiliary means (7) for determining at least one longitudinal margin of maneuver of the aircraft, which is expressed as a load factor and which relates to one of the two maneuvers of pitch-up and of pitch-down of the aircraft. The means of depiction (4) moreover present, on the display screen (6), at least one second characteristic sign which is associated with said first characteristic sign and which illustrates the longitudinal margin of maneuver.
摘要:
A method for displaying flight information includes displaying a first characteristic sign illustrating a speed vector of an aircraft. The method also includes determining a first longitudinal margin of maneuver of the aircraft as a load factor, and displaying a second characteristic sign such that a position of the second characteristic sign relative to the first characteristic sign illustrates the first longitudinal margin of maneuver.
摘要:
A device and process for aiding the driving of an aircraft running over the ground in an acceleration phase with a view to takeoff may include determining a current speed v0 of the aircraft and a value acc corresponding to a deceleration of the aircraft during emergency braking. A distance df to be traveled on the ground by the aircraft while stopping is calculated using the expression df=(v0)2/2 acc, and a stopping position of the aircraft is calculated from the distance df and a current position of the aircraft. Thereafter, the distance df and the stopping position are presented to a driver of the aircraft with the aid of an appropriate device.

The device (1) comprises a first means (3) for measuring the effective value of the velocity vector of the aircraft, a computing unit (4) which determines a display value automatically and repetitively and which comprises a filtering means (6) which filters the value measured by the first means (3) so as to form a first term, a display unit (7) for presenting on a screen (2) a characteristic sign illustrating the velocity vector whose position on the screen (2) is representative of the display value, and a second means (9) for determining the derivative of a velocity vector controlled by an aircraft pilot. The computing unit (4) further comprises a computing means (10) which determines a second term from the derivative of the controlled velocity vector and a summator (12) which sums the first and second terms so as to form the display value.
摘要:
The invention consists of a bitumen/resin composite emulsion for a road surface protection layer against the attacks of petroleum derivates, realised by mixing a first emulsion comprising at least one resin with a second emulsion comprising a bituminous binder and a resin crosslinking agent. A pigmentary preparation and/or a load made of a filler or sand or a fine sand or their combinations, can be incorporated to the first emulsion, the second emulsion or into the composite emulsion resulting from the mixture of both emulsions. The loaded composite emulsion enables the realisation of thin film-type surface coatings made of one or several layers.
