Narco Escort Ii Installation Manual Full Guide

Missing from many "incomplete" manuals is the thermal dissipation table. The Escort II generates significant heat during transmit (approx. 15 watts). The full manual provides:

The manual specifies that the mounting tray must be installed using size 6-32 stainless steel screws into a rigid instrument panel sub-structure. The unit must be within ±10 degrees of horizontal to avoid gyroscopic interference (though the Escort II is solid-state, the switch mechanisms degrade if angled).

Before cutting a panel hole, review these base specs from the manual:

RTCA Compliance: DO-138 (Environmental), DO-144 (Transponder).

Critical Note: The Escort II requires a positive ground in most aircraft chassis. Verify your aircraft's electrical bonding before installation to prevent ground loops.

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.

The Narco Escort II is a legacy "shared system" digital radio that functions as either a NAV or a COM, but not both simultaneously. Because Narco Avionics is no longer in business, full manuals are often sold as physical copies or digital scans from specialized aviation document services. Manual & Pinout Resources

Detailed Pinout & Wiring Diagram: A high-quality PDF of the Escort II 14V Pinout and Intercom Setup is available via AeroElectric, which includes intercom arrangements and specific pin functions. Full Installation/Maintenance Manuals:

Essco Aircraft: Offers the Narco Escort 110 (14V) Maintenance & Installation Manual for purchase as a printed copy or download.

eBay: Frequently lists used original Narco Escort 810/811 Maintenance Manuals, which often include the installation sections. Key Installation Specifications

Mounting: The unit is designed for instrument panel mounting and weighs approximately 3 pounds. It typically uses a mounting tray with a ramping screw that requires a 3/16" Allen wrench to secure the unit firmly into the mating connector.

Electrical Requirements: Standard installations are 14V. If installing in a 28V aircraft, a separate power converter is typically required.

Intercom Key Function: Available at connector P301 pin 12. When this pin is externally grounded through a switch and the mike key line is open, mike audio is amplified by a 50 mW amplifier and routed to audio outputs at pins 5 and 6.

Antenna Requirements: The radio requires two dipole antennas: one for NAV (often V-shaped) and one for COM (often located in the fuselage or vertical tail).

Microphone Caution: If using the intercom feature, both the pilot and co-pilot microphones must be the same manufacturer and model to prevent audio level shifts when one is disconnected.

Narco Escort II is a lightweight, digital "shared system" radio that functions as either a 200-channel VOR/LOC NAV receiver or a 720-channel COMM transceiver. Unlike standard indicators with needle movements, it uses a gas-discharge display for VOR/LOC deviations. Electrical Installation & Pinout (P301 Connector)

The unit uses a multi-pin P301 connector for primary electrical and audio interfaces. For a standard 14V system, pins 8 and 10 must be jumpered. Wiring Specification 1 & 2 +14/28V Power Input 18 AWG Red 3 & 4 Airframe Ground 18 AWG Black 5 Low-Level Audio 20 AWG Green 6 Headphones Audio 20 AWG Blue (50 mW high-level output) 8 Switched A+ 18 AWG White/Red 9 Transmitter Key 20 AWG White 11 Mike Audio 20 AWG Brown 12 Intercom Key 20 AWG Yellow (available at pin 12) 13 Mike/Phones Ground 20 AWG Black Installation Guidelines

Wiring: Use a minimum of 22 AWG for signal leads and 16 AWG for A+ and ground leads. Ensure all wires are shielded to prevent radio noise.

Protection: A 1.5 amp circuit breaker should be installed between the unit and the aircraft power bus.

Antennas: The radio requires two separate dipole antennas: a V-shape NAV antenna and a copper tubing COMM antenna. Use RG-58 A/U 50-ohm coax for the COM antenna and RG-58 4/U coax for the NAV antenna.

Mounting: The unit is typically mounted in the instrument panel using a rear support stud for stability. Intercom Configuration

An internal intercom function is activated by externally grounding pin 12 via a switch. When active, microphone audio is amplified and sent to the audio outputs at pins 5 and 6, bypassing the transmitter. If using a dual-microphone setup, both mics must be the same manufacturer and model to maintain consistent audio levels. Initial Setup & Testing

Once installed, the unit should be calibrated following the manufacturer’s instructions to ensure accuracy. Perform a thorough inspection to confirm that the installation does not interfere with the free movement of any aircraft flight controls. narco avionics escort ii - AeroElectric

Narco Escort II Installation Manual: A Comprehensive Guide The Narco Escort II remains a legendary "all-in-one" avionics solution for many general aviation pilots. Combining a COM radio, NAV receiver, and VOR/LOC indicator into a single panel-mounted unit, it was a masterpiece of space-saving design.

If you are looking to install or reinstall this classic unit, following the original technical specifications is critical for both safety and legal compliance. 1. Pre-Installation Requirements

Before sliding the unit into the panel, ensure your aircraft's electrical system is ready.

Voltage: The Escort II is typically a 14VDC unit. Ensure your bus voltage is stable.

Circuit Protection: A 5-amp circuit breaker is standard for this installation. Missing from many "incomplete" manuals is the thermal

Cooling: While the Escort II is relatively efficient, ensure there is adequate airflow behind the stack to prevent heat soak, which can drift frequency stability. 2. Physical Mounting The Escort II uses a standard lateral mounting tray.

Panel Cutout: The unit requires a standard 6.25-inch wide radio rack opening.

Depth: Allow at least 11 inches of depth behind the panel to accommodate the unit, the rear connector, and the cable service loop.

Securing: Use the specialized Narco locking hex-wrench tool to tighten the internal cam-lock. Do not over-tighten, as this can warp the mounting frame. 3. Wiring and Pin Assignments

The heart of the installation is the rear 15-pin (or 24-pin, depending on the specific Mod) Molex-style connector. Standard Pinout Highlights: Pin 1 & 2: Ground Pin 3: +14VDC Power Input Pin 4: Pilot Mic Input Pin 5: Speaker Output (usually 4 or 8 ohms) Pin 6: Phone/Headset Output

Pins 10-12: Typically reserved for external VOR/LOC needle outputs if connecting to an external CDI.

Note: Always verify your specific unit's Mod level against the wiring diagram on the chassis sticker, as Narco made slight variations during production. 4. Antenna Connections

The Escort II requires two distinct antenna inputs via BNC connectors:

COM Antenna: A standard 50-ohm VHF whip antenna. Ensure the VSWR is less than 3:1 for optimal transmission.

NAV Antenna: A "V" or "T" style dipole antenna. If you are sharing this antenna with another NAV radio, you must use a signal splitter (diplexer) to avoid signal loss. 5. Post-Installation Testing Once wired, perform the following checks:

Dimming: Verify the internal lamps dim correctly with the aircraft's lighting bus.

Squelch: Test the "Pull-for-Squelch" feature to ensure clear audio.

VOR Accuracy: Using a VOR Test Facility (VOT) or a known ground checkpoint, verify the bearing accuracy is within ±4 degrees.

Ground Comm Check: Contact a nearby FBO or Tower to confirm transmission clarity and signal strength. 6. Regulatory Compliance

In the United States, an installation of this nature requires an entry in the aircraft logbooks. If this is a new installation (rather than a "plug-and-play" replacement), an FAA Form 337 for Major Repair and Alteration may be required, along with an updated Weight and Balance report.

Disclaimer: Avionics installation should be performed or supervised by a certified A&P mechanic or an FAA-approved radio shop. Improper wiring can lead to electrical fires or loss of critical navigation equipment.

The Narco Escort II is a legacy radar altimeter (radio altimeter) used primarily in general aviation and some light turbine aircraft. The installation manual (typically Narco publication number Escort II IM or similar) is not a user guide—it is a technical document for certified avionics installers.

Over the years, avionics shops have reported recurring installation failures when mechanics rely on incomplete third-party summaries. Typical errors include:

All these pitfalls are avoided by following the full manual’s details.
