DirtyFret Posted December 28, 2015 Posted December 28, 2015 (edited) Hello, and thanks for this magnificent(:D) heli and the continued efforts to repair the fans in the cockpit. I have a few questions: -What is the EEG for the TV3-117M's ? Is it the ERD-3VM(ЭРД-ЗВМ)? What would be the correct procedure to use in high altitude operations on take off? - ECL's Full up or Emegency power switch L/R on? The manual states that in case of single engine failure in flight the "Illumination of the ЧР. ЛЕВ. (ПРАВ.) ДВ. (EMER PWR LFT (RGT) ENG) light depending on the helicopter’s weight and altitude at the moment of failure." p.151 - Does this mean that the EEG(ЭРД-ЗВМ?) switches it on automatically or does the FE do it automatically? - The (draft) manual doesn't state that in single engine flight the operative engines ECL should be lifted to the up position. Should it be lifted or only in case were rotor RPM drops? Any additional discussion or clarification pertaining to the engine,throttle and rotor RPM management is appreciated. Thanks.

AlphaOneSix Posted December 28, 2015 Posted December 28, 2015 Hello, and thanks for this magnificent(:D) heli and the continued efforts to repair the fans in the cockpit. I have a few questions: -What is the EEG for the TV3-117M's ? Is it the ERD-3VM(ЭРД-ЗВМ)? Yes. What would be the correct procedure to use in high altitude operations on take off? - ECL's Full up or Emegency power switch L/R on? ECL's in center detent and CP switches ON. The ECL's are always in the center detent unless there is an engine failure or you're testing something. The CP switches are always set to ON. I have never seen them ever turned to the OFF position. The manual states that in case of single engine failure in flight the "Illumination of the ЧР. ЛЕВ. (ПРАВ.) ДВ. (EMER PWR LFT (RGT) ENG) light depending on the helicopter’s weight and altitude at the moment of failure." p.151 - Does this mean that the EEG(ЭРД-ЗВМ?) switches ot on automatically or does the FE do it automatically? The switches are always ON, but you can only get that light to come on if one engine is inoperative. It's all completely automatic and requires no human intervention. - The (draft) manual doesn't state that in single engine flight the operative engines ECL should be lifted to the up position. Should it be lifted or only in case were rotor RPM drops? You should only pull the ECL to the full up position if there is a problem with the opposite engine where it's not producing power (i.e. it's failed). Any additional discussion or clarification pertaining to the engine,throttle and rotor RPM management is appreciated. Thanks. It's all very automatic in the Mi-8. The ECL's are normally in the center detent, and our company checklist ensures that they are in the center detent prior to engine start. Once the engines are started, you roll the throttle grip on the collective full right (which is called the AUTO position, full left is the IDLE position.) All normal (i.e. non-emergency) flight in all regimes is performed with the ECL's in the center detent and the throttle grip at full right. Rotor RPM is also managed automatically. If you are too heavy or pull in too much collective at one time, your rotor speed will droop, which is bad. Well, it's okay to droop as low as 91%, but it's best to try to keep it above 93%. As you already know, 88%-ish is where you start to lose the generators. On the high side, the max for normal flight is 101% and the max during a maneuver is 103%, but those are rare unless you dump the collective too fast. Basically, as long as the pilot is smooth with the collective, rotor RPM changes are minimal, unless you're really heavy for the conditions (i.e. hot, high). 2
