Narco Escort Ii Installation Manual Full

The keyword “installation manual full” is crucial. An "Owner’s Manual" is not enough—it only covers basic operation. A full installation manual (Narco Part Number typically 861000-xxxx, depending on revision) includes:

A genuine full installation manual includes a step-by-step test protocol using a ramp tester (like the IFR-1000). This covers:

Without these pages, you cannot legally or safely certify the installation for IFR flight.

The Narco Escort II is a compact, self-contained Nav/Com system designed for instrument panel mounting in general aviation aircraft. Unlike traditional units that require external indicators, the Escort II features an integrated "gas discharge" display that provides both frequency readouts and VOR/LOC deviation using a row of lights instead of mechanical needles. General Installation Overview

The unit is designed for cabin environments in fixed or rotary-wing aircraft. It typically operates on a 14V DC system, though 28V installations are possible with a dedicated power converter. Electrical Pinout and Wiring (P301 Connector)

The Escort II uses a multi-pin connector (P301) for power, audio, and antenna interfacing. For a standard 14V installation, a jumper is required between pins 8 and 10.

Antenna Installation

The system requires two separate antennas: one for Navigation (NAV) and one for Communication (COM). narco escort ii installation manual full

Antenna Types: Standard dipole antennas are typically used. The NAV antenna is often V-shaped, while the COM antenna is usually a whip or tubing style.

Cabling: Use 50-ohm RG-58 A/U coaxial cable for both connections.

Mounting: Antennas must be electrically connected to the aircraft ground plane. For composite or thin-skinned aircraft, a doubler plate is required for structural integrity and electrical performance. Intercom and Audio Setup The Escort II includes a built-in 50 mW audio amplifier.

Intercom Key: An intercom function is available on Pin 12. When this pin is grounded through an external switch while the mike key line is open, audio from the microphone bypasses the transmitter and is heard through the headphones.

Microphone Matching: If using a dual-microphone setup, both microphones should be the same model to ensure consistent audio levels. Mechanical Mounting

The unit is mounted directly into the instrument panel. It is secured within a mounting tray that facilitates easy removal. The rear of the unit includes a support stud to stabilize the radio against vibration. Technical Specifications The keyword “installation manual full” is crucial

Frequency Spacing: COM utilizes 25 kHz spacing, while NAV uses 50 kHz.

Display: Digital gas discharge for frequencies and deviation indicator.

Power Requirements: Designed for engine-driven alternator systems with a battery floating on the DC bus. A 1.5 amp circuit breaker is recommended.

  • Configuration: Some software requires or offers configuration during installation. Make choices that fit your needs, but be aware that default settings are often the best choice for beginners.

  • Completing Installation: Once the installation bar completes, you may be prompted to restart your computer or directly launch the application. Without these pages, you cannot legally or safely

    • A complete manual contains a full interconnect diagram showing:

    The official manual contains Section 5: Test and Calibration. Without this, your shop cannot sign off a 337 form.

    Using a ramp tester (IFR-6000 or T-40D), you must verify:

    The Narco Escort II is a 360-channel VHF transceiver operating within the 118.000 MHz to 135.975 MHz frequency range. It is designed as a slide-out unit, facilitating ease of maintenance and installation. The system is "all-solid-state," utilizing advanced microelectronics to reduce weight and power consumption compared to older vacuum tube units.
