  • Numbers of both the "Bottles Interconnect Valve" and the "Oxygen Valve" are reversed
  • There is a contradiction between closed and opened valves, which particular valve is meant to be opened or closed?

Kind regards,

This should be read "7. PITOT SYSTEM LINES OPEN, FAILURE SIMULATION SWITCHES OFF" or "7. OPEN / OFF"

 

2. Unbenannt2.jpg.8b1ee7dd4d5f603791b298f5a426a5e1.jpg

 

This should be read "9. «0» or «δ»" (depending on navigational desire)

 

3. Unbenannt3.jpg.591efdf09ecbf799553c98d7371bdbda.jpg

 

This should be read "8. ALL ON" or "8. ON" with yellow square around «NETW», «SIGNAL», «ARMS» and «INTERCOM GROUND» switches.

Can someone explain what the "take-off mode" exactly is? Never heard that before, could that be a manual error (using "take-off mode" instead of "landing mode")? Thanks in advance.

 

Take-off mode here is the position of throttle and engine operation mode, thus should remain take-off mode, but can be rephrased to make it more clear.

 

Page 89:

To set required engine operation mode in both cockpits on the left panel the throttle is installed. Throttle in front cockpit has engine operation mode markings: «STOP», triangle mark (used when engine has to be started from emergency fuel system), «IDLE», «CR SPEED», «NOM», «TAKE OFF». This throttle has «STOP» latch, used for shutting off the engine.

Thank you very much. That's what I needed.

 

Btw, the throttle is marked with "TAKE UP". Strange.

DCS document version numbers would be helpful too, it's hard to know which is what, especially without any table of changes.

System specs: Win7 x64 | CPU: i7-4770K | RAM: 16 GB | GPU: GTX 980 Ti 6 GB | Thrustmaster HOTAS | MFG rudder pedals | SATA3 SSD | TrackIR

8-81, p. 15, second paragraph:

 

"auxiliary power unit (APU) “Saphir-5” produced by the French company “Turbomeca” under license"

 

Sure it's not the other way round? Turboméca as the licensor and PBS as the licensee?

 

Good point! You are completely right, my bad. Should be: "The airplane had new air intakes and the auxiliary power unit (APU) “Saphir-5” produced under the license of French company “Turbomeca”."

Cool! :) Thanks to Zhivuchiy and derelor!

 

Yet another one for translation purposes: Could anybody provide me with the long name of the GK NII VVS facility? Cyrillic would be great as well, I just would like to provide an appropriate translation to the german readers.

 

 

ГК НИИ ВВС = Государственный Краснознаменный Научно-Исследовательский институт Военно-Воздушных Сил.

 

State Scientific Research Institute (awarded with the Order of the Red Banner) of Air Forces.

 

Hope it will help you.

ED manual, page 155

 

Ask permission to take the runway, and when permission is received take the runway and roll 10-15 meters in a straight line to align front wheel with take-off direction. Brake wheels. Check that elevator and aileron trimmers are in neutral position. Check if the RKL-41 ADF and the GMK-1AE compass show correct values (if necessary align it). Check that there are no warning signals except the «DANGEROUS ALTITUDE».

Increase engine RPM to 90% and ask ATC permission to take-off.

 

It is not possible yet in DCS World to make a difference between "ask permission to take runway" and "ask permission to take off".

Kind regards,

ED manual, page 157

 

At altitude of 50-70 meters and speed of not less than 280 km/h retract flaps (point 2) 167. Check flaps retraction using corresponding signal lamp (should be on), flaps retraction button has to return to its initial position.

 

Additionally, the mechanical indicators, located on upper surface of each wing, provide visual identification of flaps position.

Kind regards,

This is how it was in russian manual. Probably in 2.0 or on Nevada map we will have this options, therefore I suggest that we keep it as is.

8-82, p. 17, last paragraph: "The L-39С trainer became the most mass-produced modification, in the amount of 2,280 units. The USSR air forces received 2,280 airplanes (the latest one was received on January 25th, 1991)."

 

Are these figures correct or a typo? All "C" for the USSR and none for the other countries? Figures in the net vary greatly, with airwar.ru speaking of 2080 units bought by the USSR.

8-81, p. 18, first paragraph (KT-04): "Before takeoff, the KT-04, installed on a trolley, was attached to the winch cable with a special grip. During takeoff, the distance between the tug and the target was 100 m."

 

I found http://flak11.de/FlakGS-Ziele.htm which claims 800 m between tug and target. However, these are LV/LSK values and may differ from WWS figures. Is there a chance to have this clarified?

 

(However, 100 m seems quite close to me)

Typo. Many thanks.
