Embodiment Construction

[0069] An example of an embodiment of the invention is safety equipment for an amphibian, wherein the safety equipment is configured to detect a type of landing surface.

[0070] The safety equipment includes two transceivers, a first transceiver configured to operate (or transmit and receive) on electromagnetic wavelengths and a second transceiver configured to operate (or transmit and receive) on ultrasonic wavelengths.

[0071] The transceiver is configured to transmit substantially towards the landing surface (meaning substantially downward or towards the landing area when the aircraft is substantially in a normal flight condition or position) and configured to receive reflections of the emitted wavelengths.

[0072] The safety equipment comprises determining means for determining a type of landing surface from a property of reflection of said wavelength when said wavelength is reflected from said landing surface, and for outputting a signal indicative of the determined typ...

Abstract

A safety arrangement (300, 310, 320, 330, 340) for an aircraft, especially for amphibious aircraft, being configured for determining a type of landing surface (such as water / solid ground) and including: a first transceiver (301) configured to operate on electromagnetic wavelength, a second transceiver (302) configured to operate on ultrasound wavelengths, and determining elements for determining the type of the landing surface based on the properties of reflections of the electromagnetic and ultrasound wavelengths, and for outputting a signal indicating the type of the determined landing surface.

Description

technical field [0001] The invention relates to safety equipment for an aircraft and a method for determining the type of landing surface for an aircraft. In particular the invention relates to amphibians. Background technique [0002] Aircraft require landing gear for landing and takeoff. The term "aircraft" refers to a wide variety of fixed-wing and rotary-wing aircraft. Airplanes are fixed-wing aircraft that typically take off and land on runways. A landplane (operating on land or hard ground) including fixed or retractable landing gear. The retractable landing gear is retracted inside the fuselage to reduce aerodynamic drag after takeoff or during flight. (However, fixed landing gear is not retractable.) When landing on a runway, the retractable landing gear must be deployed or brought into the landing position. [0003] A seaplane is a powered fixed-wing aircraft capable of taking off and landing (landing) on ​​water. A seaplane is an airship or pontoon plane. In...
