A detection system for use in an aircraft which is able to monitor atmospheric conditions ahead of the aircraft, generate an alarm signal if adverse atmospheric conditions exist ahead of the aircraft and generate information which indicates the position of the adverse conditions so the adverse conditions can be avoided. The system is able to detect the presence of volcanic ash cloud ahead of the aircraft and, if desired, can also be used to detect a high density of sulphur dioxide gas and/or clear air turbulence ahead of the aircraft. The system monitors infrared radiation received by the aircraft, generates intensity signals representative of at least one predetermined wavelength of the radiation and compares intensity signals with reference signals or intensity signals of another infrared wavelength. If the results of the comparison indicate the adverse conditions are present, an adverse condition warning signal is generated and the device is also able to generate video display signals for producing a video display which indicates the position of the adverse conditions relative to the aircraft.
A detection system for use in an aircraft, including:
A detection system for an aircraft, including means for monitoring and receiving infrared radiation produced by an adverse atmospheric condition ahead of said aircraft, means for generating signals representative of predetermined wavelengths of said radiation, and processing means for determining the presence of a volcanic ash cloud ahead of said aircraft on the basis of said signals.
A method of detecting an adverse atmospheric condition for use in an aircraft, including:
A detection system for use in an aircraft, including means for monitoring and receiving infrared radiation ahead of said aircraft, means for generating signals representative of predetermined wavelengths of said radiation, and processing means for determining on the basis of said signals if an adverse atmospheric condition is present ahead of said aircraft and generating a warning signal when said condition is present, wherein:
A method of detecting an adverse atmospheric condition for use in an aircraft, including monitoring and receiving infrared radiation ahead of said aircraft, generating signals representative of predetermined wavelengths of said radiation, determining using said signals if an adverse atmospheric condition is present ahead of said aircraft and generating a warning signal when said condition is present, comprising the step of:
A detection system including means for monitoring and receiving infrared radiation from above the horizon, means for generating signals representative of predetermined wavelengths of said radiation, and processing means for determining whether said representative signal which is of a longer predetermined wavelength is less than said representative signal which is of a shorter predetermined wavelength and, therefrom determining the presence of a volcanic ash cloud on the basis of said determination.
A method of detecting an adverse atmospheric condition, including:
