Sling 2 Engine Start & Garmin G3X/GTN 650 Setup: Step-by-Step Guide

Sling 2 Engine Start & Garmin G3X/GTN 650 System Setup

Starting the engine and configuring avionics properly are two of the most critical phases of any flight. In the Sling 2, a disciplined, repeatable setup sequence improves safety, situational awareness, and traffic management — especially in active towered environments like North Perry Airport (KHWO).

This guide walks you through the recommended procedure used in structured flight training at Dynasty Aviation to:

• start the Sling 2 engine safely

• program and initialize the Garmin G3X

• setup the GTN 650 navcomm and flight plan

Always treat this as an advisory overview, not a substitute for your aircraft’s POH or official training.

Watch the Full Procedure

Step 1: Pre-Start Aircraft Setup

Before any electrical power is applied:

• Chock wheels and set parking brake

• Verify control lock is removed

• Confirm fuel selector is on both and fuel quantity is adequate

• Check oil level is within limits

Developing a habit of systematic setup reduces errors and ensures readiness — particularly in the busy pattern work common at Fort Lauderdale area training airports.

Step 2: Master Switch & Electrical Power

1. Battery Master ON

2. Alternator ON

3. Verify primary flight instruments initialize

4. Observe annunciators and fault messages

Once electrical power is established, allow the G3X and GTN 650 to complete their self-tests. A clean startup in the avionics stack improves situational awareness and reduces checklist omissions.

Step 3: Garmin G3X Setup

With the G3X powered:

• Confirm attitude, heading, airspeed, and altitude tapes display correctly

• Set correct barometric pressure

• Verify GPS has a 3D fix

• Load the appropriate flight plan if required

This early avionics step prevents distractions later in the taxi phase and builds confidence before radio calls or runway entry.

Step 4: GTN 650 Programming

1. Press FPL to create or pull up your flight plan

2. Enter departure (KHWO) and destination

3. Confirm waypoints and transitions

4. Set COMM frequencies for Ground and Tower

5. Adjust NAV sources if required

Programming the GTN 650 before engine start or taxi ensures your navigation picture is ready and minimizes cockpit workload during critical phases.

Step 5: Engine Start Sequence

1. Mixture to idle cutoff

2. Throttle cracked 1/4”

3. Fuel pump ON

4. Prime as required

5. Key START and monitor RPM rise

6. Fuel pump OFF after positive oil pressure

Monitor annunciators, oil pressure, and electrical indications. A smooth, consistent start sequence builds confidence and reinforces engine management discipline.

Why This Matters for Structured Flight Training

At Dynasty Aviation’s training base in South Florida, procedures aren’t memorized and forgotten. They are taught as habits.

• A predictable start reduces risk

• Early avionics setup reduces workload

• Proper programming improves situational awareness

• Practicing these skills builds pilot confidence

• Standardized flows reduce variability in student performance

Pilots searching Sling 2 start procedure, Garmin G3X Sling training, or GTN 650 setup training near Miami and Fort Lauderdale will benefit from this structured approach.
