Electrical Power Controls

2-52: Electrical power controls

1. "ТОК АКК" (Battery 1) After flipping up the cover [E + LALT + LCTRL + LSHIFT] and selecting this switch [E + LCTRL + LSHIFT], electrical power will be drawn from battery 1. When performing a ground start with no ground power, you will need to set this switch to on in order to start the APU and engines.

2. "ТОК АКК2" (Battery 2). Enable this switch to draw electrical power from battery 2. This switch [W + LCTRL + LSHIFT] also has a cover. [W + LALT + LCTRL + LSHIFT]

Note: Enable both battery 1 and battery 2 for normal operations.

3. "=ТОК АЭР ПИТ" (Ground DC power). If on the ground at an airfield or FARP, you may radio ground maintenance to provide direct current (DC) ground electrical power. Before radioing though, be sure that the SPU-9 intercom dial is set to the "НОП" ground crew position. Once this order has been given, use this switch [Q + LCTRL + LSHIFT] to activate DC ground power to start the APU and engines. This switch also has a cover. [Q + LALT + LCTRL + LSHIFT]

4. DC ground power source lamp. When DC ground power is on, this lamp will be lit.

5. "АЭР ПИТ" (Ground AC power). If on the ground at an airfield or FARP, you may radio ground maintenance to provide alternating current (AC) ground electrical power. Before radioing though, be sure that the SPU-9 intercom dial is set to the "НОП" ground crew position. Once this order has been given, use this switch to activate AC ground power to start the APU and engines. [R + LCTRL + LSHIFT]

6. "ТОК ГЕН. ЛЕВ." (Left generator) switch. After the left engine is fully operating and the throttles are in automatic mode, you may turn on the left generator. This will supply power to the DC busses and onboard batteries. [Y + LCTRL + LSHIFT]

7. “ПРЕОБР АВТ – РУЧН” (Electrical power converter auto – manual) switch. This is a three-position switch that allows DC power to be converted to AC power that is required by several onboard systems. The up "АВТ" position

provides automatic conversion, the down "РУЧН" position requires manual conversion and the middle position turns off conversion. [I + LCTRL + LSHIFT]

8. "ТОК ГЕН. ПРАВ." (Right generator) switch. After the right engine is fully operating and the throttles are in automatic mode, you may turn on the right generator. This will supply power to the DC busses and onboard batteries. [U + LCTRL + LSHIFT]

Radio and Data Link Power Control Panel

2-53: Radio and data link power control panel

This panel consists of seven switches that toggle power to the radio and data link systems on the aircraft. Prior to powering any of these systems, the aircraft will have to be supplied with AC power. These controls include:

1. “АВСК” (Intercom) switch. “АВСК” stands for Intercommunication and Radio Commutation system. This switch provides power to the SPU-9 intercom system. The SPU-9 provides simultaneous commutation with the R-800 radio, R-828 radio, ground intercom equipment, voice message system (VMS), and caution tones to pilot‟s headphones. [Z + LALT + LCTRL]

2. “УКВ-1” switch. VHF-1 R-828 radio power switch. [P + RALT + RCTRL]

3. “УКВ-2” switch. VHF-2 R-800 radio power switch. [P + LALT + LCTRL]

6. “УКВ-ТЛК” switch. Data link equipment provides jam-resistant secure communications via VHF-TLK channel for remote target designation. [O + LCTRL + LSHIFT]

Fuel Boost Pump Controls

2-54: Fuel pump controls

In addition to transferring fuel from the storage tanks to the engines using the suction-force generated by operating engines, boost pumps are employed to provide uninterrupted flow and for APU and engine start. While the boost pumps need to be on for APU and engine start, they do not always need to be on once the engines are running; it is best though to always have at least the internal front and rear pumps active as long as the engines are operating. The Ka-50 has two internal fuel tanks (forward and aft) and attachment points for two external fuel tanks on each stub-wing. Each fuel tank has a dedicated boost pump. The fuel boost pump control panel has the following controls:

1. "НАСОСЫ БАКОВ ЗАДН" Aft fuel pumps. Toggles power to the aft fuel boost pumps. [D + LCTRL + LSHIFT]

2. "НАСОСЫ БАКОВ ПЕРЕД" Forward fuel pumps. Toggles power to the forward fuel boost pumps. [A + LCTRL + LSHIFT]

3. "НАСОСЫ БАКОВ ПОДВЕС ВНУТР" Inner stub-wing station external tank pumps. Toggles power to the two inboard stub-wing station pumps that can support external fuel tanks. [F + LCTRL + LSHIFT]

4. "НАСОСЫ БАКОВ ПОДВЕС ВНЕШН" Outer stub-wing station external tank pumps. Toggles power to the two outboard stub-wing station pumps that can support external fuel tanks. [G + LCTRL + LSHIFT]

5. "ТОПЛИВОМЕР" Fuel metering system ON/OFF power switch. [H + LCTRL + LSHIFT]

Fire Extinguisher Control Panel

2-55: Fire extinguisher control panel

The Ka-50 has an extensive suite of fire monitoring and fire extinguisher systems that are controlled from the fire extinguisher panel. Each fire extinguisher system uses fire retardant contained within a pressurized bottle to flood the desired compartment. The fire extinguisher panel has the following functions:

1. "ПОЖАР ЛЕВ ДВИГАТЕЛЯ" (Left engine) fire lamp. This lamp indicates that a fire has been detected in the left engine bay.

2. "ПОЖАР ВСУ" (Auxiliary Power Unit (APU)) fire lamp. This lamp indicates that a fire has been detected in the APU bay.

3. "ПОЖАР ПРАВ. ДВИГАТЕЛЯ" (Right engine) fire lamp. This lamp indicates that a fire has been detected in the right engine bay.

4. "ПОЖАР ВЕНТИЛ" (Oil-coolers) fire lamp. If a high temperature has been detected in the oil-coolers compartment, this lamp will light.

5. "1" Automatic mode discharge lamp. If the "БАЛЛОНЫ" switch has been placed in the automatic, left, position, the fire extinguishers will automatically discharge when a fire has been detected. When in this mode, a “1” will be displayed on the lamp. Generally, keep the switch in the automatic postion unless you want to fire the second extinguisher manually.

6. "2" Manual mode discharge lamp. When the “БАЛЛОНЫ" switch is in the right position, you will need to manually press one of the four fire extinguisher buttons to discharge in case of fire. When in the manual mode, a “2” will be displayed on this lamp.

7. Discharge left engine fire extinguisher button. Press this button when in manual mode to discharge the fire extinguisher to the left engine bay. [F + LSHIFT]

14. "КОНТРОЛЬ ДАТЧИКОВ I ГР – II ГР – III ГР". Select 1st/2nd/3rd fire warning sensors groups BIT selector. [Z + RSHIFT]

Fuel Shutoff Valve Control

2-56: Fuel shutoff valve control

This panel controls flow of fuel from the fuel tanks to the engine and allows the main fuel tanks to cross feed from each other. This panel is also used to open fuel flow to the APU. Prior to APU and engine start, you will need to enable these switches.

1. "ДВИГ. ЛЕВ. – ЗАКРЫТО" (Left engine – Closed) left engine fuel valve switch [J + RCTRL + RSHIFT] and cover. [J + RALT + RCTRL + RSHIFT] Placing this switch in the up position opens the fuel valve between the fuel tanks and the left engine. Open this valve prior to left engine start. Placing it in the down position closes the valve.

2. "ДВИГ. ПРАВ. – ЗАКРЫТО" (Right engine – Closed) right engine fuel valve switch [K + RCTRL + RSHIFT] and cover. [K + RALT + RCTRL + RSHIFT] Placing this switch in the up position opens the fuel valve between the fuel tanks and the right engine. Open this valve prior to right engine start. Placing it in the down position closes the valve.

3. "ВСУ – ЗАКРЫТО" (APU – Closed) APU fuel valve [L + RCTRL + RSHIFT] switch and cover. [L + RALT + RCTRL + RSHIFT] Placing this switch in the up position opens the fuel valve between the fuel tanks and the APU. Prior to starting the APU, this valve must be open. Placing it in the down position closes the valve.

4. "КРАН КОЛЬЦЕВ. – ЗАКРЫТО" (Cross feed – Closed) fuel tank cross feed switch [; + RCTRL + RSHIFT] and cover. [; + RALT + RCTRL + RSHIFT] When this switch is in the up position, the two main fuel tanks will automatically transfer fuel between them. This helps better balance the aircraft but note that damage to one main tank can then cause both tanks to lose fuel. Unless you have damage to one of the main fuel tanks, it is better not to isolate them and allow them to cross feed from each other.

Transmission/Oil Pressure and Temperature Gauges

2-57: Transmission and engine oil pressure and temperature gauges

This set of six gauges provides monitoring of oil pressure, transmission oil pressure, and engine oil pressure for both engines.

Lighting Control Panel

2-59: Lighting control

This panel is devoted to external and cockpit lighting controls. Functions include:

1. "КОНТУР. ОГНИ" (Rotor tip lights) switch. Tip lights on the lower three blades can be turned on by setting this switch to the up position. Tip lights can be useful in helping to gauge blade clearance to nearby obstacles and for formation flying. [J + RALT]

2. "СТРОЕВ. ОГНИ” (Formation lights) switch. Formation lights are low-intensity light-strips located on the back of the fuselage and the wings. The switch has four positions that include off and three levels of brightness (10%, 30% and 100%). Formation lights can only be seen at close range, so they are often used for formation flying at night without being too visible to enemy units. [J + RCTRL]

3. "ПОДСВЕТ АГР ПКП." (SAI and ADI lighting) switch. Although most of the panels and controls can be illuminated with the cockpit panel lighting switch, the SAI and ADI must have their own lighting controlled with this switch. [K + RALT + RSHIFT]

4. "ПОДСВЕТ ПРИБОРЫ" (Night vision cockpit lighting) switch. [K + RSHIFT]. When using night vision goggles (NVG), it is best to use this setting to provide reduced illumination compared to the general cockpit lighting panel. You may further wish to adjust the brightness of the NVGs to maximize cockpit clarity. Night vision brightness adjustment is done with the “ЯРКОСТЬ ПОДСВЕТА

ПРИБОРЫ” (Brightness instruments) knob on the lower part of the control panel.

5. "ПОДСВЕТ ПУЛЬТЫ" (Cockpit panel lighting) switch. Except for the ADI and SAI, this switch turns on panel lighting for the cockpit. You would generally use such lighting when in low-light conditions and not using the night vision goggles. [K + RCTRL]

Note that the flood light switch is located along the rear left panel of the cockpit and the navigation lights are located on the overhead panel.

Electronic Engine Governors

Two ERD-3VMA electronic engine governors are installed on the Ka-50. Each Electronic Engine Governor (EEG) is part of the electronic engine control system and is intended to control the fuel flow at high gas-generator (GG) RPM and to shut down the engine in case of power (free) turbine (PT) over-speed. Each EEG functionally consists of GG RPM limitation contour and automatic PT protection and has the following functions. For the GG contour:

 Maximum GG RPM limitation as a function of the ambient temperature and barometric pressure, with the purpose of maintaining constant takeoff power.

 Maximum physical GG RPM limitation up to 101%.

When the maximum GG RPM has been reached for a given temperature and pressure, the EEG reduces fuel flow via a solenoid valve. Simultaneously, the “ОГРАН РЕЖ ЛЕВ” (LEFT ENG PWR LIMIT) or “ОГРАН РЕЖ ПРАВ” (RIGHT ENG PWR LIMIT) yellow lights on the overhead panel illuminate. For the PT protection:

 This generates an engine shut down command signal with a flashing MWL and illumination of the “n ст ПРЕД ЛЕВ ДВИГ” (LEFT ENG PT OVRSPD) and “n ст ПРЕД ПРАВ ДВИГ” (RIGHT ENG PT OVRSPD) red lights on the left portion of the main instrument panel. Simultaneously, the audio message “Раскрутка турбины левого двигателя” (Left engine power turbine over-speed) or “Раскрутка турбины правого двигателя” (Right engine power turbine over-speed) is played.

The control panel for turning EEG off and on is located on the right wall panel. There are switches for turning off and on both EEG‟s (left and right engines), a selector switch for GG channel test, and another switch to test both the channels of the PT contour. When the “ЭРД ЛЕВ” (EEG LEFT) and “ЭРД ПРАВ” (EEG RIGHT) switches are in the ON (up) position and the two “КОНТР. ЭРД” (EEG TEST) selectors are in the “РАБОТА” (OPERATION) position, the electronic governors are ready for normal operation.

The “СТ-1” (PT-1) and “СТ-2” (PT-2) channels operate independently from each other. To generate an engine shut down signal it is necessary that both channels have detected a PT over-speed with a time difference of no more than 0.2 seconds. In case of a PT RPM

over-limit detection by only one channel, or by both of them but with a time gap of more than 0.2 seconds, the signal is ignored as a false alarm and no action is taken. If during test mode with an illuminated warning light and a rotor RPM of 86.5%, the selector can be rapidly switched to the other channel (СТ-1 – СТ-2) without holding it in the middle “РАБОТА” (OPERATION) position; the tested engine will shut down.

Engine Power Indicator

The Engine Power Indicator is a tool to measure the equipment used to control engine power. Monitoring and control of the engines is based on the measurement of the compressor‟s outlet air pressure, whose value is indicated by the two yellow markers on the vertical scale. These are then compared to the central red markers on the scale that represent different engine operating modes. The position of these mode markers is proportional to the ambient air pressure and temperature. On the central index there are three red markers: “В”, “Н”, “К”. These correspond to the compressor‟s outlet air pressure at takeoff, maximum continuous, and cruise modes. To control the operation of any mode, it is necessary to compare the position of the yellow index markers with the red mode marks (В, Н, К) on the scale.
