Primary Display Overview
Display Overview
Attitude Direction Indicator (ADI): Displays the aircraft’s orientation relative to the horizon. It provides the pilot with critical pitch (nose-up or nose-down) and bank (left or right roll) information. The scale is graduated in 5º Increments.
Indicated Airspeed Indicator: Moving scale in 10 KIAS Increments with numbers displayed every 20 KIAS. Maximum indicated speed is 180 KIAS.
Indicated Airspeed/Ground Speed: Numerical indication of Indicated Air Speed and Ground Speed.
Barometric Altitude Indicator: There are two barometric altitude indicators: a tape scale and a digital readout window. The tape indicator is a moving scale with a stationary arrow displaying the barometric altitude.
Vertical Speed Indicator (VSI): Displays the aircraft's vertical speed. The 1, 2, and 3 indicate the positive or negative vertical speed in thousands of feet per minute.
Kollsman Setting, inHg: Displays the local barometric pressure setting. The operator can change the setting by turning the Universal Control Knob (UCK) when the BARO bezel key is selected on the FD. UCK Info Using the Universal Control Knob (UCK)
Ground Altitude Indicator: Displays radar altitude in a dial/digital format with associated indicators for decision height and hover altitude. Hover Altitude is indicated as a triangular pink bug on the outer ring of the Ground Speed indicator. Hover altitude can be selected from the Autopilot Control Panel.
Decision Height Display: Displays the current variable altitude decision height value selected by the operator. The operator can change the DH by turning the Universal Control Knob (UCK) when the DH bezel key is selected on the FD. Decision Height is also displayed as a circular bug on the Radar Altimeter indicator. UCK Info Using the Universal Control Knob (UCK)
Wind Speed Indicator: Displays current wind direction and velocity, in Knots.
Map Mode Indicator: Indicates Map Direction Mode, for both MD and PFD. H indicates HEADING UP, N indicates NORTH UP, T indicates TRACK UP. Can be selected using the N/H/T Button.
Heading Selected: Displays the current heading selected. Heading can be selected using the Bezel HDG Button in combination with the UCK. More information Using the Universal Control Knob (UCK). Redundant with #16
Magnetic Heading: Displays the current magnetic heading, in Degrees.
Glideslope Indicator: When a valid ILS Frequency is tuned and intercepted, displays the deviation from the glideslope path.
Course Selected: Displays the current course selected. Course can be selected using the Bezel CRS Button in combination with the UCK. More information Using the Universal Control Knob (UCK).
Horizontal Situation Indicator (HSI): Navigation instrument that combines heading, course, and navigation source information into a single display. It enhances situational awareness by providing a top-down view of the aircraft's orientation relative to the selected course or navigation aid.
Heading Selected: Displays the current heading selected. Heading can be selected using the Bezel HDG Button in combination with the UCK. More information Using the Universal Control Knob (UCK). Redundant with #11
BRG2 Indicator: Allows the operator to view the BRG2 source selected driving the BRG2 needle on the HSI or MAP display.
BRG1 Indicator: Allows the operator to view the BRG1 source selected driving the BRG1 needle on the HSI or MAP display.
NAV Indicator: Allows the operator to view the NAV source selected driving the NAV needle on the HSI or MAP display.
Turn and Slip Indicator: Shows the rate of turn and whether the aircraft is in coordinated flight.
HSI Mode Indicator: Allows the operator to see the HSI Mode selected. More information, HSI Mode
Horizontal situation indicator (HSI)
Hover (HVR)
Map (MAP)
Fuel Quantity: Displays fuel quantity on tanks 1 and 2, in Pounds, as well as total quantity on internal tanks. Fuel quantity on external tanks is not displayed here.
Turbine Gas Temperature #1, #2: Displays the exhaust gas temperature of each engine. TGT is a key indicator of engine thermal performance and is monitored to avoid overheating and ensure safe power settings during all flight phases.
Power Turbine Speeds #1, #2, Rotor Speed: Shows the rotational speed of each engine's power turbine (NP1, NP2) and the main rotor speed (NR), expressed as a percentage of nominal RPM.
Engine Torque #1, #2: Indicates the amount of torque being produced by each engine, shown as a percentage of maximum rated output.
HSI Mode Selector
HSI Mode
The standard HSI (Horizontal Situation Indicator) is displayed, combining heading, selected course, and navigation source information into a single integrated view. Note that the flight plan route (Either Sim-Created or FTP) is not displayed on this mode.
Map Mode
This mode prioritizes the background map display, prominently showing the flight plan route. It also includes BRG1, BRG2, and a reduced-format HSI indicator for basic heading and course awareness.
Note: This is a clean map with a black background and no additional overlays. For topographic maps, tactical overlays, and facility information, refer to the Mission Display (MD).
Hover Mode
Helicopter Position Indicator: Indicates the datum, position of the helicopter.
Hover Position Point: Provides a directional cue to the operator when approaching the hover position.
Hover Altitude Indicator: A graphical representation of the error between the selected hover altitude and actual hover altitude. The size and position of the hover altitude error box represent the error between the selected hover altitude and the actual hover altitude as described below:
If Selected Hover Altitude equals Radar Altitude; then the box corners lie on the inner range ring. This indicates on altitude.
If the aircraft is below the Selected Hover Height, the box increases in size until its corners lie on the outer compass ring.
If the aircraft is above the Selected Hover Height, the box decreases in size until it collapses to its minimum size.
Position of Load Indicator: Displays where the cargo is located with respect to aircraft, if external loads have been selected for pickup.
Compass Rose: Provides aircraft heading while in HVR mode. Labeled every 30°
Velocity Vector (NOT PICTURED): A green vector representing aircraft velocity magnitude and direction. The velocity vector emanates from the center of the inner range ring and points in the direction that the aircraft is drifting.
Embedded GPS/INS (EGI) Popup
The EGI Popup provides real-time information on the status of the Embedded GPS/INS system, including:
Alignment Status (e.g., OFF, ALIGNING, ALIGNED)
Time Remaining to Full Alignment
Current EGI Mode or Errors (if any)
EGI Button: Displays the Embedded GPS/INS (EGI) popup submenu, which shows the current EGI status, alignment timer, and additional INS-related information.
EGI Pop-up Display.
EGI Not Aligned
When the EGIs are not aligned, the Primary Flight Display (PFD) will appear degraded or partially blank, indicating unavailable navigation data.
The Embedded GPS/INS systems (EGIs) serve as the aircraft’s primary source of navigation, positioning, and attitude reference data, and are critical for flight operations. Proper alignment is essential before takeoff to ensure accurate heading, flight plan tracking, and system integration.
To align EGIs, locate the EGI PWR #1 and #2 Switches on the Copilot side of the centre console. Both of these switches must be turned ON, along with CMPTR PWR, to start the automatic alignment process.
Alignment has been simulated to last approximately 15 seconds. In reality, alignment on these aircraft is much longer, taking over 15 minutes and, at times, up to half an hour.
