- Please be careful with all static wicks sticking out from trailing edges before and after flight – accidentally striking or bending may break them, which will cause the aircraft to be deemed VFR-only or even entirely grounded by Galvin until it gets fixed!
- The pitot heat cover is important to be installed when the aircraft is parked.
It should always be the first item to remove when you get to the plane for a flight, and the last item to be installed after completing all other postflight tasks so that the cover cannot be melted by the pitot heat – yes, that has happened
- Please install the engine inlet plug after your flights (see this page for more information)
- Avionics: There are three extra checks that are highly recommended before every flight once the avionics master switch is on:
- Upper G5 – ESP – if you are planning on maneuvering, turn it OFF
- …so that it won’t activate the AP in the middle of your maneuvers!
- GTN750 – System – GPS Status – SBAS: Make sure all sources are ON
- Inactive GPS sources can lead to AP anomalies
- GTN 750 – System – Setup: Make sure Crossfill is ON
- Otherwise changes you make to the FPL in one device won’t show in the other
- Upper G5 – ESP – if you are planning on maneuvering, turn it OFF
The avionics in this airplane are pretty intuitive, but a learning curve is unavoidable for everyone. To spare yourself frustration and unwelcome delays using it in-flight it is highly recommended to use the free PC Trainer and/or iPad Trainer to practice use of the GTN 750/650 on the ground, and of course also read the manuals.
There are no software simulators for the G5 units or the autopilot, so reading those manuals is also a must.
Links to all manuals can be found on the cockpit page and in the drop-down menus above.
One of the more demanding tasks is to swiftly handle any curve balls ATC may throw at you to accommodate inbound traffic situations during an IFR approach. This presentation by Bruce Williams is an excellent and easy to understand step-by-step tutorial to try side-by-side on a GTN 750 simulator (see links above).
Make sure you understand the main components of this cockpit and their high-level connections (click on below image to open PDF) :
The G5 units offer a shortcut to press and hold the ON/OFF buttons in order to turn them off within 3 seconds instead of 45 – please refrain from doing that as it can get them into a state where they won’t start up after turning on the master switch the next time (if that happens, press and hold the ON/OFF button for some 10+ seconds, and the unit should start up eventually).
Normally you should not have to press the ON/OFF button on the G5 units at all.
Fuel: Please note that the digital fuel gauge on the left side of the cockpit is not connected to the GTN units – therefore, at the beginning of your flight you want to add up the numbers of the two tanks and verify / update them as needed on both GTN screens upon booting up the avionics (right after the GPS database information) for fuel planning purposes.
To properly pre-fly and use the full potential of this AP to your advantage and ease your workload in the cockpit please familiarize yourself with the AFMS and this guide published by Garmin – and of course follow the advice of your CFI.
Even more important than knowing how to use the autopilot before using it is to know how to disconnect / turn it off in case it does something you don’t expect so that you have time to figure out what happened before getting into a dangerous attitude.
NEVER FIGHT AN AUTOPILOT. If it’s not doing what you want – especially vertically -, disengage it and set the airplane up by hand.
The most common way to disconnect the autopilot is to press and release the AP DISC / TRIM INT (AP disconnect/trim interrupt) button located on the control yoke. An autopilot disconnect tone will sound, and an amber AP will be annunciated on the G5 autopilot status box.
Three other ways to disconnect the autopilot include:
- Pressing the AP Key on the GMC 507 Mode Controller
- Operating the Electric Pitch Trim Switch (located on the control wheel)
- Pulling the AP circuit breaker (know where it is in the center of the top circuit breaker panel, marked with a yellow plastic ring to help find and pull it fast)
In the event of unexpected autopilot behavior, press and holding the AP DISC / TRIM INT button will disconnect the autopilot and remove all power to the servos.
Check out this GFC500 video presentation from Sporty‘s/Garmin – it explains the whole system as well as its use in a flight scenario, including the recently added VNAV option. (That said, you still always want a CFI next to you as you learn to use the AP!)
Here is another good article talking about APs in general, definitely worth reading.
An important AP preflight element for you to think of if you are planning on practicing maneuvers such as steep turns, stalls etc. is to be present to and disable the ESP (Electronic Stability & Protection) via the upper G5, because when it senses that the aircraft is near the defined operating limit in pitch attitude, roll attitude, high airspeed, or low airspeed, this function will automatically engage one or more servos to nudge it back to the nominal operating envelope.
Warm start: Above 100°F oil temperature you typically first want to try starting the engine without priming. If that fails and you think you do need to prime after all, do not over-prime – doing so washes away engine lubrication and causes cylinder wall damage.
Cold start: Priming long enough is as important as adding enough throttle; try a bit more than both 3-5 seconds and ½ of a inch on the throttle instead of ¼ when you start.
NEVER crank an engine longer than ten seconds and ALWAYS wait twenty seconds before cranking again. You can do this up to five times. If it hasn’t started by then, give it 30 minutes to cool down or you risk causing damage.
Weight & Balance
By removing the vacuum system and replacing older avionics and servos, 3WF gained almost 56 lbs useful load in Spring of 2018; the CG moved 1.3″ (3.3cm) forward:

Compass deviation card (RADIO ON) as of April 2018:
ADS-B In / Bluetooth
This plane is equipped with ADS-B In (Traffic, WX) information to both the GTN units and also available to your EFB app (ForeFlight, Garmin Pilot) via Bluetooth.
Get the GTN750 into Bluetooth pairing mode simply by navigating via HOME > System to the Connext Setup page.
DO NOT CHANGE ANY SETTINGS ON THAT PAGE!
The Bluetooth pairing must be initiated by your portable device – look for N513WF. Pop-ups displayed on the portable device and GTN will be displayed to confirm the pairing.
Next time you fly your device should connect automatically, no need for the above procedure. If it doesn’t go to the Connext Setup page again and tap on Manage Paired Devices; check if your device is listed. If not then pair your device again.
Note: Be sure to use Bluetooth – should you look at WiFi and happen to see a N513WF-MX WiFi network, do not connect to it – the GTN WiFi should neither be on nor used as it’s for database maintenance by authorized persons only, and it will not provide you with any of the ADS-B In information you’re looking for.
Connecting that way will also provide WAAS-accurate GPS location, AHRS info and FPL synchronization between the GTN units and your EFB app.
Flight plans now have to be filed in ICAO format which asks for more aircraft equipment and capability details than the good ol’ FAA flight plan.
To help with setting up your flight plans we have created a page (find it in the dropdown menu above under > Equipment) which should do the trick – use those bits and pieces to fill out the aircraft profile in your EFB.
Removable data cards
Never remove any of the data cards from the avionics, especially not while the units are turned on. Any outdated databases on those cards are to be updated by Galvin staff only.
Cleaning the displays
Please use the display cleaning cloth in the glove compartment.
The GTN units have displays that are coated with a special anti-reflective coating that is very sensitive to waxes and abrasive cleaners. CLEANERS CONTAINING AMMONIA WILL HARM THE ANTI-REFLECTIVE COATING.
It is very important to only clean the displays using a clean, lint-free cloth and an eyeglass lens cleaner that is specified as safe for anti-reflective coatings.
Attention Zulu 3 Headset users
If you have a Zulu 3 headset and experience issues with the mic bias feature – after ~5-10 seconds the headset cuts out after working fine (both speaking and hearing) – the way to resolve it is by setting the stereo/mono DIP switch inside the headset controller into the stereo/OFF position (kudos to Bruce Nourish for this tip!)
- During preflight and after flight, whenever you walk around or move the plane with the tow bar please close the doors at least to the first noticeable notch (so that they hold in place) so as to avoid sudden door swings with wind gusts.
- Please always install the control lock on the yoke after every flight. It’s part of the checklist and a required step. It may not be gusty when you come back, but wind conditions can change quickly, and the ailerons and elevator control surfaces need to be protected from sudden movements.
