|
When is fuel and ignition introduced in a normal engine start? |
4 seconds after 15% NG |
|
|
When does the engine start control valve close? |
When commanded closed by MC VIA FADEC at approx 65% NG |
|
|
What are the three FADEC closed loop circuits and their respective valves? |

2900-3300 PSI |
|
|
What are the utility and booster hydraulic pressure limits? |
2900-3200 PSI |
