Onboard equipment Kurs-MP-1


Equipment COURSE-MP-1 allows the use of foreign systems of navigation and landing VOR and ILS, along with domestic "Code" and SP-50, as well as to samoletovozhdenie using ARC.

To perform these tasks on board the following equipment is installed:

  • NKP-4 - course navigation device;
  • DLI - RMI indicator;
  • Remote (selector) select the radio;
  • control unit (panel setting half-sets);
  • Bearing Selector.

The navigational course device NKP-4 is installed on the dashboards of the first and second pilots and is intended for piloting the aircraft in the navigation and landing modes. Piloting is carried out on the course and glide path arrows (slats) in the same way as in any zero-indicator. On the internal movable scale NSC-4 with the price of dividing 2 ° against the fixed triangular index located at the top of the device, the course of the aircraft is counted. The outer fixed scale, having the division 10 °, serves to count the course angles of radio stations. Since the NCP-4 is connected to the navigator's indicator (UW), it repeats all of its readings.

The device has two arrows: yellow (narrow) and white (wide). Yellow narrow arrow intended for reference only chickens with one of the first set of the ARC. On some aircraft, this arrow may not be involved. White broad arrow an Instrument Setpoint is driven ratchet located in the lower right corner of the NKP-4. Set a course to be only in the piloting of command arrows (in director mode).

The central part of the device is occupied by a null indicator with white and yellow course and glide bars blenker respective colors.

Aircraft navigation system VOR carried out using only the white (ESP) strips, if a given path line coincides with the line bearing the lighthouse BOP, the crew must hold the directional arrow within the white circle.

When landing using both arrows: localizer and glide path.

Radio Magnetic Indicator RMI installed on the dashboard of both pilots and serves for the reading of a magnetic course, bearing (azimuth), bearings and radio stations and lighthouses.

Device RMI also has two scales: the inner - moving with divisions and external 2e - fixed, which through 45 ° applied triangular indexes, or (in the last editions) point four corners of the course: 240, 290, 70 and 120 °.

Since RMI is connected directly to giroagregatam exchange system (CC), internal sliding scale against the fixed triangular index is always measured MK aircraft regardless of the position switch on the remote control ESP system navigator.

The narrow and wide arrows of the device are designed to count the course angles and azimuths (bearings) of radio stations and VOR beacons. At the same time, a narrow arrow shows the bearing and course angle of only the first (main) set of ARK tuned to a driving radio station, or the first half set KURS-MP-1 tuned to a BOR radio beacon; wide arrow indicates the bearing and heading angle of only the second (spare) set of ARC or second half-sets of equipment Kurs-MP-1, tuned to a VOR beacon.

The device can be switched to the first or second set of ARC or KURS-MP-1 half-set via radio station or VOR ground beacon by two flags at the bottom of the device: the left with a narrow handle and the right with a wide. The positions of the handles (flags) are fixed with inscriptions in located under them. viewing windows, respectively: in the left - "ARK1" and "VOR1" right - "ARK2" and "VOR2".

Depending on the position of the left switch narrow narrow needle will show either the CSD station to which you are ARK1 or VOR azimuth beacon, spent the first half-sets COURSE-MP-1. Broad Arrow, depending on the position of the right switch will show a wide CSD radio station to which you are ARK2 or VOR azimuth beacon, spent the second half-sets of equipment Kurs-MP-1.

Remote radio choice is to select the radio, which will be implemented Navigation and piloting modes of navigation and landing (RSBN, VOR, ILS and SP-50).

On IL-18 located above the center console dashboard in the cockpit and has three switch. In the upper left corner of the dashboard is a switch that determines the system over which the approach. It has two positions: "HUD" and "SP-50». In the upper right corner of the dashboard mounted switch marker that en route must be put in the position of "landing".

At the bottom of the console there is a switch with five fixed positions:

  • 1) "RSBN" - signals from the "Svod" system are sent to the NKP-4 instruments of the first and second pilots;
  • 2) “SP-50” signals are sent to the NKP-4 of the ship commander only from the “Svod” equipment, and to the NKP-4 of the co-pilot - only from the SP-50 system of the first semi-set KURS-MP-1. When leaving failure of the first half-sets of equipment Kurs-MP-1-4 device NCP copilot automatically switches to the second semi-kit (you need to set the frequency of the two half-sets SP-50 airport landing);
  • 3) position "1" - on NKP-4 of the ship's commander and co-pilot, only the first half-set works. In case of its failure, the second half-set is automatically connected. This mode of operation of the apparatus Kurs-MP-1 when the main landing Systems ILS and SP-50;
  • 4) provision "Joint". - signals to the NKP-4 of the ship commander come only from the first semi-set, and to the NKP-4 of the second pilot - only from the second semi-set. No redundancy is provided in this position;
  • 5) position «2» - signals to both NCP-4 come only from the second half-sets. In this position, the second semi-kit is not reserved automatically first, since it is provided in the event of failure of the first half-sets and automatic switching.

The control unit is available in every half-sets, and is intended for the setting of the half-sets on the frequency of the ground beacons VOR, SP-50 and HUD.

Beacon frequency range 108-118 MHz are set using the drum and flag. When installed in a range 108,1 -

111.9 MHz of odd frequencies automatically turns on the ILS mode, and when you set the range 112,0-117.9 MHz and even frequencies in the range 108,2-111,8 MHz, the VOR mode.

Bearing Selector is a part of two half-sets COURSE-MP-1 and serves to provide a flight on a specific direction (azimuth), strictly oriented in space relative to the ground beacon VOR system. This is done by setting the value of the azimuth of the selector.

His second assignment - to determine the exact value of the azimuth beacon VOR in solving navigational problems.

At the top of the selector are two illuminated signs: Blind - "On", and the right - the "From". According to fire one of them can be seen on the direction of flight of the lighthouse or from him. In the center of the selector there is a window, behind which is a drum digitized from 1 3605 up with divisions 1 °. In the lower right corner of the selector knob is located, by means of which a predetermined value is set bearing, which is used by the flight of the null indicator, and in the lower left corner - the check box for changing the azimuth of the 180 ° with concurrent redeployment phase.

Automatic transfer phase occurs when flying VOR beacon. This ensures correct readings null indicator arrows NKP-4 in further maintaining the aircraft in the desired course (the arrow on the right - LZP right arrow to the left - the left LZP). Consequently, at the time of flight of the lighthouse enough with the right lower arm just to clarify the meaning of a new bearing on who will perform further flight of the aircraft.

Manual transfer of the flag and changing the value of the azimuth of the 180e performed only when the plane before they reach the lighthouse, made a U-turn close to 180 °, to further flight in the opposite direction. In all other cases, the flag should be lowered down.


The performance capabilities of the equipment Kurs-MP-1

  • 1. Simultaneous operation on two different VOR beacons - the main option when flying on routes equipped with a VOR system. The azimuths and CSD of both beacons are indicated on the RMI instruments, and the azimuths are indicated on the outer scale of the navigator's pointer only when the switches (narrow and wide flags) of the RMI are set to the "BOP1" and "BOP2" positions.
  • 2. Simultaneous operation of one semi-set in the VOR mode, and the second in the ILS mode is used when performing a pre-landing maneuver if the VOR beacon is located near the landing aerodrome. In this case, it is more expedient to carry out the work in the "Joint" mode. The first semi-set is tuned to the ILS beacon, the second to the VOR beacon. At the moment of entering the area of ​​the localization beacon ILS, the switch on the radio system selection panel is set to position "1" and to reserve the landing channel, the second half-set switches to the ILS beacon by setting the frequency at which it operates on the control unit.
  • 3. Simultaneous operation of two semi-sets in the mode of landing beacons SP-50 or ILS - the main option when performing an approach using course-glide path beacons.

The two half-sets tuned to a frequency of landing aerodrome.

In order to reserve a landing switch on the remote radio selection is set to «1». In exchange, both navigation device NKP-4 signals are from the first half-sets of equipment Kurs-MP-1.

Problems to be Solved equipment Kurs-MP-1 in navigation mode

  • 1. Determination of the magnetic azimuth (bearing) from the aircraft position to the VOR ground beacon.
  • 2. Flight along the equal-signal zone of the given magnetic azimuth of the ground beacon (if it coincides with the LZP) using a null indicator.
  • 3. Determination of the plane's position by the magnetic azimuths of two VOR beacons and the determination of navigation elements in the steady state of the plane's flight.
  • 4. If the aircraft is equipped with the "Svod" equipment, then it is possible to solve all the tasks provided for by this system. In this case, when the ship's commander mode is installed on the RSBN radio selection panel, the ship's commander mode will work similarly to the KPP-M system of the Svod system.

Turning equipment Kurs-MP-1 and determine its readiness to work:

  • 1. Switch on the power supply of the equipment with the help of five filling stations on the navigator's TsRSh: "KURS-MP signal", "KURS-MP-1", and "KURS-MP-P", "RMI-I", and "RMI". It must be remembered that the equipment should be turned on 5-10 minutes before the start of work to warm up its elements, stabilize the work and work out the tracking systems to their original position.
  • 2. Set the type of work switch on the radio systems selection panel to the position of the system selected for use, and also set the ILS-SP-50 and Route-Landing marker switches to the appropriate positions.
  • 3. On the control units, set the frequency of the selected VOR, SP-50 or ILS beacon.
  • 4. Set the azimuth on the selector.
  • 5. Set the switches on the RMI of the ship commander and co-pilot to the appropriate position: "ARK1", "VOR1", "ARK2", "VOR2".
  • 6. At the navigator, set the "ARK1", "BOP1" and "ARK2", "BOP2" switches to the required position.

Ready half-sets of equipment for use in navigation mode is determined by:

stopped illuminating exchange ("K") indicator lights on the remote radio choice (left - the first half-sets, the right - the second);

White blenker closing exchange rate on the instruments NKP-4.

Willingness to work in half-sets of equipment in the "Landing" mode is determined by:

stopped illuminating exchange ("K") and glide ("G"), the warning lights on the remote selection of radio systems;

the closing exchange rate of white and yellow glide blenker on devices NKP-4.

In modes "Navigation" and "landing" on the display located on the dashboard left and right drivers must illuminate the selected alarm mode: BOP, SP-50 or HUD.


Application of the system KURS-MP-1

When flying on beacons VOR:

  • 1. Check if the equipment is powered on.
  • 2. Set the frequency of the selected VOR beacon on the control unit. On the light board for the commander and co-pilot, the inscription "THIEF" will appear.
  • 3. Listen to the callsigns of the VOR beacon by setting the switch of the subscriber station SPU to the position "RK1" for the first half-set and to the position "RK2" for the second, and the switches "ARK.1, V0R1 "and" ARK2, V0R2 "set to" VOR1 "and" VOR2. " This scale can be read CSD VIII beacons VOR azimuth, reckoned on the arrows of the ARC.
  • 4. On the radio system selection panel, set the equipment operating mode ("1", "Joint", "2").
  • 5. Set the RMI flags to the positions "BOP1" and "BOP2".
  • 6. To fly to or from the VOR beacon, set the magnetic azimuth taken from the map on the selector. In this case, the inscription should light up, respectively "On" or "From".

In all cases, regardless of whether perpetrated by a flight to the lighthouse or from the magnetic azimuth is close to the magnetic course and differ from it only by the amount of convergence of the meridians, the difference of the magnetic declination airplane seats and the installation of the lighthouse, the angle of drift and error exchange system .

After setting the specified azimuth, the position of the aircraft relative to the LZP is determined by the position of the head rail of the NKP-4, the exit to it is performed and followed by the zero-indicator in the usual order. At the same time, during the entire flight, the RMI arrows show the azimuth of the VOR beacon, to which the semi-sets of equipment are tuned. COURSE-MP-1.

Exit the lighthouse BOP as follows: MK is taken equal to the azimuth, removed from the RMI, set selector and azimuth plane piloted by coursework bar NKP-4.

When removing the VOR azimuth beacon for foreign fixed scale VIII against the sharp edges of arrows pointer, you must set the switches "ARK1-VOR1" and "ARK2-VOR2" to "VOR1" and "VOR2."

When landing system ILS:

  • 1. Before turning on the power to the equipment, make sure that the brackets NKP-4 are in the crosshairs of scales, if not, install them in this position by mechanical correctors. Keep in mind that when the power devices These adjustments are prohibited, as it would lead to a distortion of evidence NKP-4.
  • 2. Switch on the power supply of the KURS-MP-1 equipment.
  • 3. Set the switches on the radio system selection panel to the "ILS", "Landing" and "1" positions.
  • 4. Set the operating frequency of the ILS beacon on the CH5 control units of both semi-sets.
  • 5. Set the switches on the RMI to the positions "ARK1" and "ARK.2" or "VOR1" and "VOR2", depending on which radio equipment will be used when constructing the pre-landing maneuver.

Ready half-sets of equipment Kurs-MP-1 to work with ILS beacons is determined by:

  • a) extinguishing of course ("K") and glide path ("G") signal lamps on the radio system selection panel;
  • b) closing the course (white) glide path (yellow) blenkers on the NKP-4 devices.

When landing system SP-50:

  • 1. Correction of the null indicator is made in the same way as when landing on the HUD. It should be remembered that correction is also prohibited here when the power supply of the equipment is turned on in order to avoid incorrect readings of the NKP-4 instruments.
  • 2. Turn on the power to the equipment.
  • 3. On the radio system selection panel, set the switches to the "SP-50", "Landing" and "1" positions.
  • 4. Set the operating frequency of the SP-50 beacon of the landing airfield on the control units of both semi-sets.
  • 5. On the RMI, set the switches to the positions "ARK1" and "ARK2".
  • 6. Check the electrical zero of the equipment.

The commander should check the installation of switches on the control knobs radio selection in the "SP-50» and «1» and press the knob "Balance-I» in the instrument balance. If the exchange rate strap NKP-4 not located in the center of the scale zero-indicator, the rotation of the right and left knob is "Balance-1» to set the bar in the center of the cross, then release the knob.

Pen "Balance-II» do the same operation for the second link set polukomp- equipment previously put the switch on the remote radio switch to select «2». Keep in mind that you can check the electrical zero pro

drive only within the localizer SP-50 rejected when strips course, the warning light extinguished and closed blenker NKP-4.

Willingness to have sex sets of equipment Kurs-MP-1 to work with beacons SP-50 determined:

  • a) extinguishing of course ("K") and glide path ("G") signal lamps on the radio system selection panel;
  • b) closing the course and glide path blenders on the NKP-4 instruments.

During piloting using NCP-4 on the last straight as a system SP-50, and ILS system are the usual method of approach for instrument landing system.
