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 devices of the first and second pilots;
  • 2) “SP-50” on the NKP-4 of the ship's commander signals are only sent from the Svod equipment, and on the co-pilot NKP-4 - only from the SP-50 system of the first half 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) “1” position - only the first half-set operates on the NPC-4 of the ship’s commander and co-pilot. In the event of its failure, the second half is automatically connected. This mode of operation of the apparatus Kurs-MP-1 when the main landing Systems ILS and SP-50;
  • 4) position "Joint". - signals to the ship commander NKP-4 are received only from the first half set, and to the second pilot NKP-4 only from the second half set. In this position of reservation is not provided;
  • 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 switches on the HUD mode, and when setting the range of 112,0 — 117.9 MHz and even frequencies in the range of 108,2 — 111,8 MHz, the BOP 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 work on two different VOR beacons is the main option when flying along highways equipped with a BOP system. The display of azimuths and KUR of both lighthouses is carried out on RMI devices, and the indication of azimuths on the outer scale of the navigator pointer is done only when the switches (narrow and wide flags) of RMI are set to the “VOR1” and “VOR2” positions.
  • 2. Simultaneous work of one half-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 work in the “Joint” mode. The first half set is configured on the ILS lighthouse, the second - on the VOR lighthouse. At the moment of entering the ILS landing beacon zone, the switch on the radio system selection panel is set to “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. The simultaneous operation of two half sets in the mode of the SP-50 or ILS landing beacons is the main option when performing an approach to landing on course-glide 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 magnetic azimuth (bearing) from the aircraft to the VOR ground beacon.
  • 2. Flight along the equisignal zone of a given magnetic azimuth of the ground beacon (if it coincides with the LZP) using a null indicator.
  • 3. Determining the location of the aircraft on the magnetic azimuths of the two VOR beacons and the determination of the navigation elements during steady-state flight mode.
  • 4. If the plane is equipped with the “Svod” equipment, then it is possible to solve all the tasks envisaged by this system. In this case, when installed on the console selection radio- "RSBN" systems of the mode of the commander of the ship will work similarly to the CAT-M system "Code."

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 TSSR of the navigator: “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 for 5 — 10 minutes before starting work to warm up its elements, stabilize the work and test the tracking systems to their original position.
  • 2. Set the type of work switch on the radio system selection console to the position of the system selected for use, and also set the HUD — SP-50 switches and the marker “Route — Landing” switches to the appropriate positions.
  • 3. On the control units, set the frequency of the selected VOR beacon, SP-50 or ILS.
  • 4. Set the azimuth on the selector.
  • 5. Set the switches on the RMI of the ship’s commander and co-pilot to the appropriate position: “ARK1”, “VOR1”, “ARK2”, “VOR2”.
  • 6. At the navigator, set the switch "АРК1", "ВОР1" and "АРК2", "ВОР2" to the desired 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 the power on of the equipment.
  • 2. Set the frequency of the selected VOR beacon on the control unit. On the light panel at the commander and the second pilot will appear the inscription "VOR".
  • 3. Listen to the call of the VOR beacon by setting the switch of the SPU subscriber unit to the “RK1” position for the first half set and to the “RK2” position for the second one, and the switches to the “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 selection panel, set the operation mode of the equipment (“1”, “Comp.”, “2”).
  • 5. Set PMI checkboxes to “ВОР1” and “ВОР2”.
  • 6. To fly to the VOR beacon or from it, set the magnetic azimuth removed from the map on the selector. At the same time, the inscription “On” or “From” should light up.

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 of the equipment, make sure that the strips 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. Turn on the power supply of the KURS-MP-1 equipment.
  • 3. Set the switches on the radio selection panel to the “HUD”, “Landing” and “1” positions.
  • 4. To install on the HNXXX control of both half sets the operating frequency of the HUD beacon.
  • 5. The switches on the RMI should be set to the “ARK1” and “ARK.2” or “VOR1” and “VOR2” positions depending on which radio equipment will be used to build the pre-planting maneuver.

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

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

When landing system SP-50:

  • 1. The adjustment of the null indicator is done in the same way as when landing on the ILS system. It should be remembered that the adjustment is also prohibited when the equipment is powered on to avoid incorrect readings of the NKP-4 devices.
  • 2. Turn on the power equipment.
  • 3. On the radio selection panel, set the switches to the positions “SP-50”, “Landing” and “1”.
  • 4. Install the working frequency of the SP-50 aerodrome of the landing ground on the control units of both half sets.
  • 5. On РМИ to install switches in positions «АРК1» and «АРК2».
  • 6. Check the electrical zero of the instrument.

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

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.
