    Abstract: A wide field scanning laser obstacle awareness system (LOAS) for use on-board an aircraft is provided. The LOAS serves for alerting an operator of obstacles posing a risk of collision with said aircraft. The system comprising: a light source for generating a pulsed laser beam of light; a light detector; a plurality of optical elements for directing said pulsed laser beam from said system with a predetermined pattern scanned azimuthally over a wide field, said plurality of optical elements also for receiving reflections of said pulsed laser beam from at least one object along said predetermined pattern and directing said laser beam reflections to said light detector. The predetermined pattern includes a variation in elevation of the directed pulsed laster beam in relation to an elevation of the aircraft. Additionally, the system has means for determining substantially the azimuth position of the directed pulsed laser beam, means for determining substantially the elevation of the directed pulsed laser beam, and a display apparatus including an image screen for displaying a limited field of view, wherein the wide field of view of the system extends substantially beyond the field of view of the image screen. A processor means is coupled to said light detector, display apparatus, azimuth position determining means and elevation determining means for determining the location of the at least one object in range, azimuth and elevation in relation to a flight path of the aircraft. The processor means drives the display apparatus to display an indication representing the at least one object in range, azimuth and elevation. The indication of the at least one object comprises an image of a bar. The bar image is disposed vertically at the far left of the screen of the display apparatus when the object location is azimuthally outside the field of view of the display apparatus to the left, and the bar image is disposed vertically at the far right of the screen of the display apparatus when the object location is azimuthally outside the field of view of the display apparatus to the right.
