Aspen EFD1000

General description

The Aspen EFD1000 panel consist of three instruments, the primary flight display (PFD), the navigation display (ND) and the bezel. Together they form the EFD1000 in it's original aspect ratio (400x760 px). You can scale the panel as a whole to make it fit in your instrument panel, usually replacing the attitude indicator and gyro compass or HSI. The original panel size is 503x1007 px, representing the instrument screen in it's real pixel size. The instruments in the panel were made in twice the size, assuring the image quality stays to an optimum.

Primary Flight Display

The primary flight display consists of four parts: airspeed, attitude, altitude and data bar.

Airspeed

The airspeed becomes visible at 20 knots up to a maximum of 450 knots. The airspeed tape has 4 different color markings, which can be set manually if you select the EFD1000 PFD in the panels list. The following settings can be made:

• White lower: Vso, stall Speed with landing configuration, that is flaps out and landing gear down.
• White upper: Vfe, known as Maximum Flap Extended Speed. This is the speed in which you can fly with flaps extended.
• Green lower: Vs, stall speed with a “clean” aircraft configuration.
• Yellow lower: This is the Vno upper limit, this where the part between Vno and Vne begins. Normally it is only allowed to fly in this part when being in smooth air.
• Red lower: Vne, this is the 'Never Exceed Speed'.

The indicated airspeed turns red when exceeding Vne. On top of the airspeed tape is the IAS indicator value. This IAS value can be set with the left Mode/Sync button and is also represented by a bug along the airspeed tape. The IAS is for pilot reference only, and can be used to help you keeping your desired speed.

Attitude

The attitude indicator holds more than just the attitude, it contains:

• Roll indicator: Indicates roll/bank with marks at 0, 10, 20, 30, 45 and 60 degrees roll.
• Slip indicator: Indicates side slip, one rectangle indicating the equivalent of a full ball deflection.
• Attitude indicator: Roll and pitch with red chevrons at 15º and more nose up, and 10º and more nose down.
• Flight director: Magenta colored flight director.
• Navigation source indicator: Indicates to which source the HSI is connected, either Nav1 or GPS1.
• CDI: Green triangle indicating course deflection in dots, turns hollow when deflection is greater than 2 dots.
• GSI: Green triangle indicating glide slope deflection in dots, turns hollow when deflection is greater than 2 dots.
• Minimums setting and warning: Shows the minimums altitude set and a minimums warning when descending below set minimums altitude. Minimums altitude can be set between 0 and 15.000 feet with 10 feet increments.

When the bus voltage drops below the minimum value, a battery warning indicator will be shown and the device will start to run on it's internal battery. The battery lasts for approximately 30 minutes, after this the device will turn off. Set your aircraft default bus voltage in the user properties, either 14 or 28 volt.

Altitude

The altitude tape shows the altitude from -500 feet up till 40.000 feet, and a couple things more:

• Minimums indicators: Green triangle indicating 500 feet above minimums setting, yellow hollow triangle indicating between 100 and 200 feet above minimums, red and yellow triangle indicating set minimums altitude. Descending below set minimums altitude triggers a one second tone.
• Altitude bug: Indicates the altitude set on the autopilot. A tone sounds and the alerter settings window turns yellow 200 feet before reaching the set altitude, the yellow warning extinguishes after 15 seconds. The alerter becomes active when deviating more than 200 feet from your set altitude.
• Trend vector: This is the magenta bar along the altitude tape, showing the expected altitude within the next 6 seconds.

The window on top of the altitude tape shows your altitude alerter setting. In this instrument the alerter value is connected to your autopilot altitude setting, and can be set with the right Mode/Sync dial.

Data bar

• TAS: True airspeed in knots, visible above 20 knots.
• GS: GPS ground speed in knots.
• OAT: Outside air temperature, either in Celsius or Fahrenheit. Can be set in the PFD user properties.
• Wind speed and angle: The speed and angle of the wind on the aircraft. Becomes visible when the wind speed is higher than 10 knots and the aircraft is in the air.
• Barometric pressure setting: Either in Pascal (mB) or Inches Hg (in). Can be set in the PFD user properties. The barometric pressure setting can be adjusted with the right Mode/Sync dial.

Navigation Display

CDI navigation information

On the left top corner of the instrument you will find the 'Selected CDI Navigation Source Information Block'. This displays the available data from either Nav1 or GPS1. For Nav1 either the frequency or if available the name of the source is displayed. Below this, if there is a valid signal, the bearing, and if there is a DME signal as well there is the (DME) distance to the station and below that the time in minutes to reach the station.

Center top

From left to right: Set course for the HSI (CRS), the magnetic direction in degrees, autopilot heading bug setting (HDG). Below this there is a rate of turn indicator, with a range of 0 to 6 degrees per second. The inner white tick represents a half standard rate turn, the outer white tick represents a standard rate turn. When exceeding 6 degrees per second a white triangle is displayed.

Navigation display

Either in 360 or ARC mode. Press the button on the right side of 360 or ARC to switch between the two. Holds a CDI, connected to either Nav1 or GPS1. The green arrow represents the OBS course setting, and will show a deviation bar when there is a valid signal. The deviation bar turns hollow when the deviation becomes more than 2 dots. A to / from indicator is present as well, either on the needle or besides the CDI indicator in ARC mode. The aircraft in the center can be either a fixed wing or helicopter, this can be set as a user property when selecting the ND in the panels tab. Along the compass runs a bug indicating the autopilot heading, and a blue diamond indicating the GPS ground track.

Vertical speed indicator

The vertical speed is indicated as a number with 20 feet increments below +/- 1000 feet per minute, and 100 feet increments above +/- feet per minute. Vertical speed is displayed up to +/- 10.000 feet per minute. In 360 mode the vertical speed is displayed on a graph bar as well. The text and graph bar become visible above +/- feet per minute.
