A night vision goggles aided flight simulator system for simulating night flight operations, the system comprising - a computer programmed with flight simulator software to calculate a flight simulator image (A1,A2); - a projection screen configured to receive the flight simulator image (A1,A2); - a light projector configured to project the flight simulator image (A1,A2) onto the projection screen ; and - a view tracking device configured to measure a viewing vector (V) of a night vision device ; characterized by - a perforated plate and/or light reduction filter mounted between the projection screen and the night vision device ; - wherein the system is configured to mask the projected flight simulator image (A1,A2) as a function of the measured viewing vector (V), wherein the masking comprises dividing the projected flight simulator image (A1,A2) into a central part (A1) that is in a field of view (FOV) around the viewing vector (V), and a peripheral part (A2) that is outside the field of view (FOV); wherein the central part (A1) of the flight simulator image (A1,A2) is projected with an increased brightness with respect to an intended brightness, while the peripheral part (A2) is projected with a relatively low brightness corresponding to an actual nightly light level or not projected at all to reduce an amount of indirect light scatter of the peripheral part (A2) into the central part (A1) and into the night vision device ; wherein the increased brightness of the central part (A1) is reduced back to the intended brightness before entering the night vision device by the perforated plate and/or light reduction filter such that any remaining indirect light scattering of the peripheral part (A2) into the night vision device is further reduced thereby increasing contrast of the central part (A1) as viewed through the night vision device . - a computer programmed with flight simulator software to calculate a flight simulator image (A1,A2); - a projection screen configured to receive the flight simulator image (A1,A2); - a light projector configured to project the flight simulator image (A1,A2) onto the projection screen ; and - a view tracking device configured to measure a viewing vector (V) of a night vision device ; characterized by - a perforated plate and/or light reduction filter mounted between the projection screen and the night vision device ; - wherein the system is configured to mask the projected flight simulator image (A1,A2) as a function of the measured viewing vector (V), wherein the masking comprises dividing the projected flight simulator image (A1,A2) into a central part (A1) that is in a field of view (FOV) around the viewing vector (V), and a peripheral part (A2) that is outside the field of view (FOV); wherein the central part (A1) of the flight simulator image (A1,A2) is projected with an increased brightness with respect to an intended brightness, while the peripheral part (A2) is projected with a relatively low brightness corresponding to an actual nightly light level or not projected at all to reduce an amount of indirect light scatter of the peripheral part (A2) into the central part (A1) and into the night vision device ; wherein the increased brightness of the central part (A1) is reduced back to the intended brightness before entering the night vision device by the perforated plate and/or light reduction filter such that any remaining indirect light scattering of the peripheral part (A2) into the night vision device is further reduced thereby increasing contrast of the central part (A1) as viewed through the night vision device . <EOS>
