Gradual engine power loss, then engine shuts down

[RagnarDa]

I know I was probably overloaded for that weather (not according to the Mission Editor though). I haven't quite figured out the throttle settings and you can see me trying to figure it out on the track and my electric power goes out when I put it in full collective. When I press RShift+PageUp/RShift+PageDown or RAlt+PageUp/RAlt+PageDown it only seems to alternate between two states (Idle or Auto?) but I think it should be Idle-Normal-Auto-Full. There doesn't seem to be a RPM-Low warning (not implemented or not IRL) or maybe I missed a switch somewhere. Anyway I couldn't get the RPM over 91% and then when I fly it gradually decreases until I eventually have a electric power loss and crash into the ground. Possible I missed a anti-icing switch somewhere. I then fast forward with engine running for a bit and then the engine shuts down. I can't tell if I was out of fuel because I don't know where the fuel gauge is and the rearm-dialog is bugged.

 

So to sum up my questions:

- Throttle settings?

- RPM-warning?

- Fuel-gauge?

- Anti-icing?

- Bug?

Will take a look when I get home from work, but in the meantime:

Fuel gauge is located on the navigators panel. The gauge with a yellow center, and a knob to select wich tank to display (or CYMMA) for total.

 

IIRC throttle should be "full right" and the governor handles actual power output according to collective?

- Anti-icing?

 

Just curious: Is "icing" implemented in DCS? I have read someday somewhere here that it is not.

Thanks Teo! I found this also: http://www.digitalcombatsimulator.com/en/products/magnificent_eight/?PAGEN_2=2

 

About low-rpm warning: Im guessing it's the voice warning system that hasn't been implemented yet.

 

I think icing is modeled as I think I crashed the Blackshark at least once because of it.

Icing is definitely in the game. There are a number of missions for the 50 that require you to use it or die :)

Nice! It's good to be wrong :smilewink:

Thanks guys for info.

I found the deicing panel and what do you know! The "Icing" - warning light was in fact glowing. I put the de-icing things on and then I tried the same mission and did a nice flight between Kobuleti and Nalchik (over the mountains) and achieved a pretty respectable altitude in the process:5000m with a full rocket load ( 6 x S-8 )! I haven't found the outside air temp gauge so maybe there is none.

 

Edit: I also noticed the ECL (throttle setting sticks left of the collective) has not two but three stages. I'm guessing Idle-Auto-Full but I don't know. I managed to kill both my engines when experimenting with it.

Oh! And anyone figured out the doppler nav thing? My guess is the top number is distance traveled but the others?

From the Mi-17 manual:

 

7.6.,[lVlCC-15 Doppler system

(1) Functionally check the ,[lVlCC-15Doppler system proceeding as follows:

(a) Set the selector switch on the Doppler monitor panel (behind of the

co-pilot) to MEMORY (nAMrlTb).

(b) Set the LAND-SEA("C-M") and OPERATION-MONITORING ("K-P")

selector switches to LAND ("C") and OPERATION ("P"), respec*

tively.

© Close the DOPPLER (,QL-1CC) circuit breaker, and set the DOPP

(,QL-1CC) switch and, if necessary, the DOPPLER LIGHT (nO,QCBET

,QL-1CC) switch to ON (BK11). The TEST (KOHTP), "M" and "B" an*

nunciators on the monitor panel and the 'Tl'' annunciator on the

ground speed and drift angle indicator, and the DOPP FAIL (,QL-1CC

OTKA3AJ1) annunciator on the RH instrument panel should come

on.

(d) Test the Doppler system for solving the test problems by succes*

sively setting the selector switch on the Doppler monitor panel to 1,

2 and 3. The readings of the hovering and low speed indicator

should not differ by more than ±2.5 km/h and ±0.5 m/s respectively,

from the values indicated on the monitor panel, and the readings of

the ground speed and drift angle indicator should be 136 ±3.5 km/h

and 0 ± 1

0

,

respectively.

(e) Test the Doppler system in the SEA (MOPE) mode by setting the "C*

M" (land-sea) selector switch on the ground speed and drift angle

indicator to "M" with the monitor panel selector switch set to SPEED*

136 (CKOPOCTb-136), DRIFT·O(CHOC-O).

The ground speed should rise by 3 km/h. Leave the "C-M" selector

switch either in "C" or "M" position depending on the type of an an*

ticipated flight - overterrain or over sea.

(f) Test the coordinate indicator, for which purpose set the TRACK-KM

(nYTb KM), XTK DISTANCE-KM (60KOBOE YK110HEHL-1E-KM),

GRIVATION (yro11 KAPTbl) digital readouts to zero by operating

the "H", "B", "B11", "Bnp". "-" and "+" keys. With the Doppler monitor

panel selector switch set to SPEED-136 (CKOPOCTb-136),

DRIFT-O (CHOC-O), a ground speed reading of 136 ± 3.5 km/h and

a drift angle reading of 0 ± 1

0,

depress the ON (BK11) key on the co*

ordinate indicator. With the Doppler system operating properly, the

FORWARD (BnEPE,Q) digital readout of the coordinate indicator

should display 11.3 km in 15 min.

(g) Check the computer for correct processing of the test problem intro*

duced from the ground speed and drift angle indicator by setting the

"K-P" selector switch to "K".

The ground speed reading should be 306 ±3.5 km/h, and the drift

angle reading should be 15±11

0.

 

(h) Check the doppler aystem for selection of the MEMORY mode by

setting the monitor panel selector switch to MEMORY (nAMFlTb),

and the ground speed reading should change by not more than ±4

km/h and the drift angle reading by not more than ±3°.

The 'Tl'' annunciator on the ground speed and drift angle indicator

should come on simultaneously.

After completion of the above checks set the "K-P" selector switch to

"P", and the monitor panel selector switch to OPERAT (PA60TA),

The time required for warming up of the ,QL-1CC-15 doppler system at

ambient temperatures above -40°C is 5 min, at lower temperatures

this time is at least 15 min.

Ok had a look in the Mi-17 manual and the English labels for the Doppler panel are (from top down):

- Course Deviation KM (buttons Left, Right)

- Distance KM (buttons Back, Fwd)

- Map Angle (buttons -,+)

- buttons Off, On

 

My guess is you set a course with the "Map Angle" button and it keeps counting how far you traveled in that direction aswell as how far off-course you are. Really cool!

Yes! This seems to be how to use it. Set the distance to a negative number (to have it "count down") and the deviation counter will display if you're left of the course ("BAEBO") or right of it ("BnPABO").
