- Nota adicional1
- One function of the engine anti-ice system is to maintain a flow of heated air at the Pt2 probe to prevent ice formation and blockage. Strong evidence [rom the accident Investigation -- namely the postimpact closed position of the engine anti-ice valves, valves which are electrically motor driven and thus not susceptible to position changes by impact loading -- indicates that the engine anti-ice system was off at the time of impact. The CVR recording substantieted that the engine anti-ice system had not been used during t h e pretakeoff ground operation. Therefore, the Safety Board concludes that the engine anti-ice system was not used by t h e crew of Flight 90; that ice accumulation blocked the inlet of the Pt probe on both engines;

- Because compression produces heat and pressure, some pneumatic aircraft systems tap into the source of hot compressed air from the engine compressor (bleed air) and use it for engine anti-ice, airfoil anti-ice, aircraft pressurization, and other ancillary systems after further conditioning its internal pressure and temperature.
