Patent ID: 8352187

Claim:
A method for monitoring parameters of an aircraft, the aircraft comprising a first display means, a second display means, and a plurality of measurement means, the method comprising: performing a first measurement and a second measurement of a first air speed parameter by means respectively of a first measurement means and of a second measurement means; performing a third measurement of said first air speed parameter by means of a first laser anemometer; the method further comprising: A) performing a fourth measurement of said first air speed parameter by means of a second laser anemometer; B) comparing at least one of said measurements of said first air speed parameter with a predetermined speed threshold; C) when at least one of said measurements of said first air speed parameter is less than or equal to said predetermined speed threshold: determining a first value and a second value of a second air speed parameter on the basis respectively of said third measurement and of said fourth measurement; and displaying said first value and said second value determined respectively on said first display means and said second display means; and A) when said first air speed parameter is greater than said predetermined speed threshold: determining a third value and a fourth value of said second air speed parameter on the basis respectively of said first measurement and of said second measurement; and displaying said third value and said fourth value determined respectively on said first display means and said second display means, as replacement for those currently displayed.
