The aircraft's capability is defined by a major 2023 panel modernization featuring a dual Aspen Evolution glass cockpit with synthetic vision, supported by a top IFR suite including a Garmin GTN 750 and GTN 650, an S-Tec autopilot, and an L-3 Lynx NGT-9000 transponder for ADS-B In/Out compliance....

Avionics

PFD

Aspen Evolution 1000 Pro Max - Avionics PFD, newly installed in 2023. Features include crisp primary flight display with integrated Synthetic Vision Technology (SVT) for unparalleled situational awareness, especially in low visibility. The display also integrates ADS-B Traffic (via the Lynx transponder) directly onto the moving map and visual field.

MFD

Aspen Evolution MFD - A second Avionics MFD, also new in 2023, serving as the dedicated Multi-Function Display. It provides navigation mapping, weather datalink (subscription required), traffic, and can display a full suite of engine data from the JPI monitor, creating a clean, integrated, and highly capable glass cockpit environment.

GPS

Garmin GTN 750 - Primary Navigation/Communication Suite (IFR Certified): GTN (installed 2016): The centerpiece, combining large, touchscreen moving map with powerful IFR-certified GPS navigator, VHF comm, VOR/ILS receiver, and audio transceiver. Serves as the primary flight management system. GTN (installed 2016): full-function, IFR-certified GPS/NAV/COM unit acting as fully redundant and complementary system to the GTN Provides complete backup navigation and communication capability.

S-TEC - S-TEC Autopilot System (installed 2016). A capable, two-axis autopilot integrated with the Garmin GTN navigators for smooth and precise en-route and coupled approach guidance.

Audio

PS Engineering PMA450B - PS Intercom/Audio Panel (installed 2019). A premium, stereo audio panel with digital clarity, Bluetooth connectivity for music and phone calls, and an advanced intercom system with auto-mute and multiple input options.

ADSB

ADS-B In

L-3 Lynx NGT-9000 - transponder (installed 2016). This is a top-tier, all-in-one unit providing Mode-S ES transponder functionality with integrated dual-band ADS-B "OUT" (for compliance) and "IN." It pipes a wealth of data to the Aspen displays, including FIS-B weather (graphical METARs, NEXRAD, TAFs, etc.) and ADS-B Traffic from ground stations and other equipped aircraft, with visual and aural alerts.

Weather

Traffic

EMS

JPI Engine Monitoring Unit - JPI Provides detailed, continuous readouts for both including Exhaust Gas Temperature (EGT) and Cylinder Head Temperature (CHT) for each cylinder, oil temperature and pressure, fuel flow, and more. Critical for precise management and health trending. Supplies clean, displays for primary and system data: dual tachometers, manifold pressure, fuel quantity/pressure, and bus voltage, offering modern alternative traditional analog gauges.

Additional Equipment

Air Conditioning

ARCTIC 24V Focal Wall - ARCTIC air conditioning unit providing effective cabin cooling for pre-flight and ground operations.

Exterior Lighting

Whelen LED - LED collision avoidance lights (strobe/nav/position) and a LED tail light for superior brightness, reliability, and energy efficiency.

Sun Protection

Rosen - visors for pilot and co-pilot sun protection

Door Hardware

Webco - upper latch for secure closure. -Electric seal for tighter, quieter cabin and mechanical device to hold the cabin securely open during pre-flight.

Standby Instrumentation
