The current windscreen provides some protection at the slower speeds flown during the final phases of the T-38 landing pattern. However, during climbs, cruise, and descents below 10,000-feet the T-38 is normally flown at speeds of 240-to-300 knots which presents a bird strike hazard by larger birds to the pilots. The T-38 low level missions are of particular concern because they are flown at speeds of up to 420-knots. Based on training requirements, the altitude for T-38 low-level missions has decreased to 500-feet above ground level along with increasing the number of sorties required. Although the Air Force plans student load reductions, the relative number of high-speed, low-level navigation sorties will increase. 收起
