WolfK33 Posted May 7, 2013 Posted May 7, 2013 Hi all, I just tried the campaign mission "Patrols". At the beginning I´m told that as the bird is so heavy I´m supposed to set the governor switch to manual, then increase rpm, take off, then set governor to auto again. Same for landing. Well, it didn´t work. As the governor switch has "Auto" and "Emer(gency)" I suppose that by "manual" the "emer" setting is ment. I set the triangular switch to the "emer"-setting and used the button mapped to increase turbine rpm on my throttle but nothing happened. I tried decrease turbine rpm (saw the switch move on the collective in game in both cases) and nothing happened. Then I set the triangular switch to "auto" again and then the turbine rpm increase/decrease worked. Now, isn´t that the wrong way around ?!? I tested in the mission editor with the same results: Triangular governor switch "emer" (down, broad side of the triangel), yellow warning light comes on, but no effect of turbine rpm decr/incr. Triangular switch to "Auto" (up, "pointy side"), turbine decr/incr works. If I change the rpm with the switch in the auto setting, like lowering so much the low rpm warning comes on and then switch to "emer", the rpm comes back up. Switch to "Auto" again, rpm goes down... Is there something wrong or am I being completely stupid ? I really don´t know which is the case...:cry:
JesseJames38 Posted May 7, 2013 Posted May 7, 2013 From what i read and understand the RPM increase and RPM Decrease is for when the governer is engaged. When the governer is disagaged the rpm is controlled by the twist grip on the collective. So when the governer is disagaged you use the twist grip to increase or decrease the rotor RPM. when the governer is engaged you use the RPM increase and RPM decrease to change the rotor speed. Jesse.
WolfK33 Posted May 7, 2013 Author Posted May 7, 2013 That makes sense so far, but my twist-grip throttle is already maxed out with the normal starting procedure. How can I use that to further increase the rpm ? Maybe it´s just a language problem combined with me being tired and stupid :-/ That briefing is confusing me ;-) Perhaps someone who already did that mission can describe exactly what he did ?
HuggyBear Posted May 7, 2013 Posted May 7, 2013 Haven't played that mission, but the instructions in the briefing might be incorrect. Below 4000 ft there will be up to 10 psi TQ less power available than in Auto, above 4000 up to 10 psi more. What is the starting altitude in the mission? Jesse is correct regarding the governor. While in Auto you can beep up the N2 to near its maximum. - Bear Pacifism is a shifty doctrine under which a man accepts the benefits of the social group without being willing to pay - and claims a halo for his dishonesty. - Robert A.

Adi Posted May 7, 2013 Posted May 7, 2013 I'm having trouble with this mission too - especially when I'm trying to take off in a slideshow :(
wess24m Posted May 8, 2013 Posted May 8, 2013 "Yes, looks like the mission may not be passable at default play in the release build. Will try to test again and fix up for the next update." __________________ - EB
WolfK33 Posted May 8, 2013 Author Posted May 8, 2013 Well, I managed to take off but with a lot of low rpm howling, same with landing later to drop my troops but had a stupid "didn´t pay attention"-crash a little later. Running takeoff wasn´t really possible as the farp is really crowded in that mission. I can´t check the starting altitude now, but you start at the standard campaign farp at Kutaisi. It was mainly that the briefing was confusing me, probably just me misunderstanding it.

Jesse. This is what I understand too but I tested on this module that the governor will take your inputs through the GOV RPM switch even the GOV switch is on EMER position but you'll see the result (or I should the "surprise") once the GOV switch back on AUTO position. :doh: I don't know if this is a bug or not. Does someone know? Tks FlyingFrog

Does someone know? Tks FlyingFrog This is correct. When in Emer Gov the engine receives fuel through the emergency metering valve which is directly controlled by the throttle. The main metering valve (Auto Gov) is still receiving all the normal inputs such as N1, T1 (inlet section air temp), P1 (input section air pressure), Throttle position and N2 Governor position (the Gov Beep switch). So both sides of the FCU (Main and Emer) are operating continuously, the Gov Auto/Emer switch just selects which side is controlling the fuel flow. As mentioned previously in this thread, the Emer fuel scheduling is incorrect at this stage. With throttle at full and collective at ground, selecting Emer fuel should cause a torrent of fuel input and an immediate overtorque/overtemp.

dahui Posted June 24, 2013 Posted June 24, 2013 So theoreticly you should Add Collective, and then switch the Emer Governor? Or reduce RPM and then switch?
HuggyBear Posted June 24, 2013 Posted June 24, 2013 Throttle to idle, then Gov Emer, then advance throttle to desired N2/NR, usually 6400 (gives a little room for error as throttle is manipulated), then throttle and collective as desired. There's also an in-flight method involving setting 94% N1 (IIRC) then switching but the throttle-idle method is simplest/easiest. - Bear 1 Pacifism is a shifty doctrine under which a man accepts the benefits of the social group without being willing to pay - and claims a halo for his dishonesty. - Robert A.
