ESI-500

Pilot’s Guide 1-1

Description

Introduction

CHAPTER 1

DESCRIPTION

Figure 1-1: ESI-500

The Electronic Standby Instrument System is comprised of the panel

mounted ESI-500 Electronic Standby Indicator and the optional remote

mounted MAG-500 Magnetometer. The system provides the ight

crew with the display of attitude, slip, altitude, airspeed, and heading.
The ESI-500 provides a means of setting barometric correction and
adjusting the display brightness. In addition, functional upgrades are
available for navigation information and the display of synthetic vision,
including terrain and obstacles.

The ESI-500 is comprised of the following integral components: Active
Matrix Liquid Crystal Display, menu push button, a rotating knob
with push button, ambient light sensor, battery pack, solid state rate
sensors, accelerometers, and pressure transducers. A micro-SD card
slot is located on the front bezel and is used for software and database
updates. Pitot/Static port connections and one 44 pin connector are
located in the rear of the unit. Refer to Figure 1-1.

Synthetic Vision Display

ESI-500

Pilot’s Guide1-2

Description

Functional Description

The ESI-500 has interfaces for input and output of ARINC-429 data,
discrete output, outside air temperature input, dimming bus, RS-485
interface between the ESI-500 and MAG-500, and an I2C interface to
the DCM-500.

The battery pack automatically powers the ESI-500 and MAG-500
(if installed) without interruption upon loss of main input power. The
battery pack has three lithium ion cells that are recharged using aircraft
power. The battery pack includes monitoring and safety functionality
that provides continual operational checks and oversight of operation
to ensure the battery cannot be overcharged, overly depleted or
detrimentally charged due to temperature limitations.

Pitot and static pressures are measured through pitot and static ports
located on the rear of the unit.

The Data Conguration Module (DCM-500) is a solid-state device
that retains software and hardware conguration information for the

ESI-500. The DCM-500 is permanently attached to the aircraft via the
wiring harness.

A magnetometer (MAG-500) or an ARINC-429 heading source is
required for the optional display of heading.

Synthetic Vision is a 3-dimensional display of terrain and obstacles,
based on GPS location of the aircraft, attitude, altitude, and heading.
Synthetic Vision provides situational awareness to the pilot by providing
a means to aid in visually acquiring potential impact threats of terrain
and obstacles. Synthetic vision uses a terrain database consisting
of DTED (digital terrain elevation data) and an obstacles database
for the display of obstacles. Terrain is shaded to give dimension to
the terrain, water is shown in blue, and gridlines are shown to aid in
determining relative distances. Terrain coloring gradually varies based
on terrain elevations from green at lower elevations to brown to white
at higher elevations.

ESI-500

Pilot’s Guide 1-3

Description

Functional Description (continued)

1. When congured to operate with a MAG-500 for heading

reference input; the use of heading is not authorized to operate in

the following regions due to magnetic eld unsuitability:

• North of 70° N latitude

• South of 70° S latitude

• North of 65° N latitude between 75° and 120° W longitude

(northern Canada)

• South of 55° S latitude between 120° and 165° E longitude

(south of Australia and New Zealand)

The heading will fail if the magnetic dip angle exceeds 82º.

Attitude and air data information is still usable.

Limitations

If the aircraft does not already have a TAWS or Terrain alerting system

installed, the Synthetic Vision should be congured to display alert

shading (red and yellow) of the 3D terrain display, for caution and
warning annunciations of terrain or obstacle impact.

The navigation function can be congured for VOR/ILS or GPS or

both. The VOR/ILS provides the following display indications: VOR/
ILS Indications, Navigation Source, Selected Course, To/From
Indicator (VOR), Lateral Deviation, BC Annunciation (Auto detected
with a heading input), Vertical Deviation (ILS), and Marker Beacon.

The GPS provides the following display indications: Navigation Source,
Selected Course, Lateral/Vertical Deviation, To/From indication, and
Desired Track. The GPS also provides own ship position for the
Synthetic Vision and for the Terrain alerting system

ESI-500

Pilot’s Guide1-4

Description

Limitations (continued)

3. The Synthetic Vision (SVS) option has the following limitations:

• Areas with densely populated objects (exceeds 500 objects in
a ¼ degree square area) and are >200ft AGL may not show all
obstacles on the display (e.g. windmill farms).

• The Synthetic Vision alert function (red and yellow shading of
the 3D terrain display) does NOT meet the requirements of
TSO-C151 (TAWS) or TSO-194 (HTAWS).

• The Synthetic Vision function only works when the aircraft is
between 70° N and 70° S latitude.

• For QFE operation the Synthetic Vision must be disabled in the
menu.

2. Battery operation is inhibited due to low and high temperatures as
follows:

• Battery will not discharge when temperature is: > +65°C
(> +149°F)

• Battery will not charge when temperature is:< +5°C and >+40°C
(<+41°F and >+104°F)

• Battery capacity not guaranteed when battery temperature is
< -20°C (<-4°F). Battery may not be available when battery
temperature is < -20°C or > +60°C (<-4°F or >+140°F)

• Storage or operation in extreme high temperature >+90°C
(>+194°F) may cause the chemical fuse in the Battery Pack to
permanently disable the battery

Battery operation can also be inhibited due to low input voltage.

Refer to the troubleshooting section for corrective actions.

5. When the normal air data aiding source is lost for three minutes
or if the Pitch or Roll value is greater than 35° for three minutes
the ESI-500 can operate in an Attitude Degraded Mode, which
means that the ESI-500 is not operating within the normal
performance parameters. The pilot is alerted to this by an amber
“ATT DEGRADED” message on the display.

• Attitude information continues to be shown, but at a lesser
performance.

Introduction

CHAPTER 2

OPERATION

This chapter describes the operation of the Electronic Standby Instrument
System. Details for display elements are provided in Chapter 3.

Power On

1. Depending on the aircraft use either the battery switches or
avionics master switch to apply power.

2. The indicator transitions through the startup sequence (Self Test

and System Identication).

3. The unit will begin normal start up displaying the splash
screen followed by the database acknowledgement screen (if
applicable).

4. If applicable press the Menu button to continue startup.

5. The unit transitions to normal mode operation beginning with
aligning attitude.

6. The alignment of attitude may require up to three minutes
to complete. The attitude message and progress bar remain
showing on the page until the unit is properly aligned. Refer to
Figure 2-1.

7. After alignment is complete the unit is in normal operation mode.

Pilot Advisory

For ESI-500 functions that require data from an external source, the
pilot should be familiar with the equipment that is providing the data.
For example, which GPS provides the data for the Synthetic Vision and
the GPS navigation displays, which NAV receiver provides the data for
VOR/ILS displays, and if heading data is not provided from the MAG­500, what equipment is providing the heading or track data for the
direction display. This will help the pilot to understand how these ESI­500 functions are affected by their source equipment, such as failures of
the source equipment or how different modes of operation of the source
equipment can affect the ESI-500 displays.

ESI-500

Pilot’s Guide2-2

Operation

Alignment

The ATT ALIGNING message is shown in the center of the screen with
a green progress bar below it. Refer to Figure 2-1. After alignment the
ESI-500 enters normal operation. Refer to Figure 2-2.

The alignment of attitude may require up to three minutes to complete
depending on the motion of the aircraft. The attitude message and
progress bar remain showing on the screen until the unit is properly
aligned.

During alignment heading is invalid and navigation information is
removed from the screen (if applicable).

Figure 2-1: Example of Attitude Aligning

In-air alignment should only be performed during

straight and level ight without acceleration.

CAUTION

NOTE

Alignment accuracy depends on current ight conditions and the
ability to maintain straight and level ight throughout the alignment

process. During abnormal conditions, such as high turbulence, the
unit may not be able to align. The status bar may show negative
progress and/or hold at zero progress until conditions improve.

Database Acknowledgement Screen

This screen is shown only if the Synthetic Vision option is enabled
via the option activation. The Database Acknowledgement screen
displays the following information: Terrain database name and cycle,
terrain database effective date, obstacle/NAV database name and
cycle, obstacle/NAV effective date, obstacle/NAV expiration date, and
the Synthetic Vision System disclaimer.

Splash Screen

The Splash screen provides the following information: System Name,
System Model No., Software part number, Firmware part number, and
if detected a DCM-500 error message.

Normal Operation

An example of the ESI-500 in normal operation is shown in gure

2-2. Display features such as heading tape/readout, vertical speed

readout, metric readout, and navigation information are congurable

and shown for reference only.

NOTE

The ESI-500 display coloring contrast of sky versus ground, or
above and below the horizon, differs between the normal display
and the display with the synthetic vision overlay. The synthetic
vision terrain overlay coloring gradually varies based on terrain
elevations from green at lower elevations to brown to white at
higher elevations. Pilots should become familiar with the synthetic
vision terrain coloring and how it contrasts with the sky depiction.
