Bouli306 Posted October 6, 2019 Posted October 6, 2019 (edited) Whenever the engine is shutdown in flight the EPU will autostart and show a run light with HYDZN and AIR light which is perfect. After engine restart the EPU shows only a runlight. It should show a AIR light and/or a HYDZN light depending on power setting: Low Power (<82-90%)HYDZN and AIR light on (and run light) High power (>82-90%) only AIR light (with run light) Edited October 6, 2019 by Bouli306
F16FLCS-SME Posted October 13, 2020 Posted October 13, 2020 I tested this today. It seems that after airstart, the EPU shutsdown and all indications (RUN,AIR,HYDRAZINE) are off. According to -1 thats wrong: "When the airstart is completed and usable thrust is regained, turn the JFS off. Reset the main generator using the ELEC CAUTION RESET button and verify MAIN GEN and STBY GEN lights are off. Cycle the EPU switch to OFF and then back to NORM." It means EPU should keep running until reset by the pilot.
