Garmin VNV

The Garmin G1000/Perspective combined with the Garmin GFC 700 Autopilot can be a great tool in descent planning.  When you want to end up at pattern altitude a certain distance from the airport or you get a clearance to cross a fix at a certain altitude, Garmin VNV is a great tool.  Here’s how to use it.

VFR Garmin VNV Use

Let’s say you want to end up at pattern altitude 3nm from your destination, but you don’t want to descend down into the bumps before you have to.  Here’s how to set it up:

  • Go to the Flight Plan page on the MFD
  • Press the ATK OFST soft key on the bottom of the MFD.  It stands for Along Track Offset, which, in laymen’s terms, means you are setting a point along your track a certain distance from your destination.  In this case, it will be 3nm
  • Input the distance using either the keypad or the small FMS knob and press enter
  • Select the altitude you want to be at (in this case pattern altitude) and press enter
  • You will see a point 3nm before you destination appear on your magenta line and a Top Of Descent (TOD) appear where you need to start your descent
  • 1 minute before the Top Of Descent, an indicator will appear next to your altimeter
  • To have the GFC 700 Autopilot fly the descent for you, you have to do two things
    • Set the Altitude bug for the desired altitude
    • Press VNV on the autopilot
  • All you have to do now is manage power

Let’s say you are told to cross a fix at a specific altitude.  Here’s how to use Garmin VNV to plan it out.

  • Go to the Flight Plan page on the MFD
  • Turn the cursor on and highlight the altitude blank next to the fix in the flight plan
  • Input the desired altitude
  • You will see a Top Of Descent (TOD) point appear along your course where you need to start your descent
  • 1 minute before the Top Of Descent, an indicator will appear next to your altimeter
  • To have the GFC 700 Autopilot fly the descent for you, you have to do two things
    • Set the Altitude bug for the desired altitude
    • Press VNV on the autopilot

  • Flying to the Bahamas

    A couple weeks ago, my employer informed me that he wanted to take a group to Nassau, The Bahamas. I thought, no big deal, this should be an easy trip. The more I started to read, though, the more I realized it wasn’t going to be just a “normal” trip.

    If you aren’t a member of AOPA, I would highly recommend joining. AOPA’s website was where I started researching. They actually have a checklist to help you along the way.

    The first step is getting the paperwork started. All souls on board are going to need a valid passport. In our case, a couple of passengers need to get theirs. Since it was a little shorter notice, we had to go through the expedited process. It’s fairly simple. A quick internet search gave me a couple of people that helped the process along.

    Next was making sure the aircraft had all it’s paperwork. The airworthiness certificate was easy as it’s always in the plane (or should be).

    The registration certificate was next to check. We recently upgraded to the King Air 350 so we had to make sure we had the original issuance registration certificate. The Bahamas supposedly doesn’t allow Temporary Certificates and I really didn’t want to test that policy.  Thankfully after a couple of calls between owner and the FAA we got the original.

    The aircraft and pilot are both also required to have an FCC Radio License. This is only for international flying, but not an everyday thing pilots think about.

    After that was flight planning. I use FltPlan.com. The actual filing of the flight plan was very easy. I use the prescribed routes from the website. In the remarks section of the flight plan put ADCUS (Advise Customs). This advices ATC to let customs know of your arrival. It’s basically an added safety net in case you forget to call ahead or your flight times end up being way off.

    The other item when dealing with flight planning is dealing with eApis. There are numerous companies who will provide this service for you. I elected not to use one of those. If you go to the CBP website, you can set up an account and do all of it yourself. Take your time and really plan the flight out well to make sure your arrival times are as close to real time as possible. If you’re way off, this will make any customs agent very frustrated and that is not something you want to be dealing with.

    Approach charts and en route charts are another hurdle. Thankfully Foreflight has you covered. With my subscription, I already had en route charts. The approach charts were the real issue. In the Bahamas, the only places that have approved instrument approaches is Nassau and Freeport. Fortunately, we were going to Nassau. Foreflight does charge almost $400 for the Caribbean and Bahamas charts.  Emailing the FBO is a good option as they can usually supply approach plates for international flights.

    You’ll also need a CBP sticker. This goes on the outside of the aircraft showing customs you’re in the system. This can be found on the CBP website as well. It takes a little bit to get the
    sticker in the mail. However, once you pay for the sticker, the receipt can be used in place of the sticker.

    The final thing I focused on was picking an FBO. I chose Jet Aviation. They had CAA which gave us a Jet fuel discount. Their facility was excellent and staff was very friendly. The thing that put it over the top for me was how they handled customs. I emailed Jet Aviation all the information for myself and passengers and they pre-filled all the customs forms for me. When we arrived, customs took all of five minutes and then my passengers were out the door.

    While in Nassau, I stayed at Breezes Resort. It’s all inclusive so that helps keep the costs down for your owners if you’re a corporate pilot. It’s next to some of the other bigger resorts so there were shuttles available to get to other amenities. The only complaint I might have was the power kept cycling on and off and the internet wasn’t reliable. This proved challenging when trying to plan for the return trip.

    The return trip required a lot of the same preparation. Again it was nice to have a good FBO to help prepare the paperwork required to clear customs. Jet Aviation handled the General Declarations for me and my passengers. All I was required to do was file the flight plan and file eApis, which was actually challenging while my internet at the resort was on the fritz.

    Don’t forget to call US Customs at your Port of Entry! As this was Ft. Lauderdale for us, I called them twenty four hours in advance as prescribed. The customs agent was friendly and helpful with any questions I had. I think the best advice I can give throughout this whole experience is call ahead and ask lots of questions! Did I say that already?

    The morning of the return trip went off with no hitches. Again, Jet Aviation had set up a driver to pick me up and he was on time. Jet Aviation had all the General Declarations paperwork pre-filled out for myself and passengers. Again, I use FltPlan.com to file my flight plans. Their service performed flawlessly even though I had heard rumors of flight plans not going through. To curb my bet, I talked with the staff at Jet Aviation and they made a call to tower for me to verify that the flight plan had gone through; of course, it had.

    The actual flight out of Nassau was pretty uneventful. The last real hurdle I had was dealing with customs in Ft. Lauderdale, and hurdle it was. When we landed at FLL, ground instructed me over to customs ramp. There was no one to tell us where to park on the ramp. This was extremely frustrating.

    A Learjet taxied in prior to us and had taken up most of the ramp but, we found a spot and shutdown. Once we shut down, no one came out to our aircraft. I walked in to talk to someone and was greeted by a Boarder agent who was less than helpful. Since the Learjet had parked first, they got to go through first. Evidently, we were not allowed in the building until they were done. This didn’t make my owner too happy!

    Be prepared, though, if another airplane is on the Customs ramp before you arrive.  You are not supposed to get out of the airplane until a Customs agent comes and meets you, even to go to the bathroom.  This can result in large fines.

    Once we were allowed in, the process went smoothly. We had to put all of our bags through the x-ray machine. Beyond the x-ray machine, CPB didn’t require any other security measures. On other crossings I’ve done, CPB had opened up bags and sifted through clothes, so just doing the conveyor belt was a surprise. The rest of the trip was fairly commonplace. We stopped in Destin FL for dinner before making our final leg into Dallas. All in all, it was an excellent trip and I’m excited to do another one.

    Ryne Bergren works for a Part 91 operation in Dallas flying a King Air 350. Being a Part 91 outfit, he doesn’t get to rely on a “dispatch” or “company” to help with any international flight planning. This was a learning experience for him. Hopefully this will be a help to anyone for future trips.

  • Garmin GFC 600 Autopilot Certified for the Piper Meridian

    In the fall of 2021, Garmin announced the long awaited confirmation that the Garmin GFC 600 autopilot is now certified for the Piper Meridian. The Garmin GFC 600 autopilot has been certified for all other types of the Piper PA46 line of aircraft, but the Meridian was last in line. The airplane has to have been manufactured prior to 2009 and have Avidyne avionics, Meggitt, or have been retrofitted with a Garmin G500 (no G1000 aircraft since those already have the GFC 700 autopilot).

    The Garmin GFC 600 autopilot is the ultimate digital autopilot. The integration with the Garmin G500, GTN 750 and GTN 650 units is a beautiful thing. The autopilot communicates with all the heading and altitude bugs, flies approaches smoothly, and even has a level button.

    In the latest technological marvel from Garmin, Garmin Safe Glide, the GFC 600 autopilot is critical in reducing pilot workload in an engine failure situation. It flies the airplane for you and takes you to the nearest airport, reducing the stress and allowing the pilot to troubleshoot the situation.

    Texas Top Aviation recommends Abilene Aero in Abilene, Texas for any and all avionics installs. They have worked with several of our customers in the last year, are extremely knowledgable and do excellent work. Call them for a quote on a new Garmin GFC 600 autopilot in your Piper Meridian.

  • Cirrus Simulator Training

    Let’s face it: airplanes are not the best classrooms. The propeller is running, the engine is making lots of noise, the pilot is attempting to multi-task and the instructor is barking orders. That’s almost as much overstimulation as being a parent to 4 kids under 10 (I have experience in that arena!). That’s even before takeoff!

    At Texas Top Aviation, we have observed many situations where a simulator would be an excellent way to introduce different concepts and supplement training. Now, in our Austin Executive (KEDC) office, we finally have a really good simulator.

    Meet the Noble Flight Simulator, the next best thing to a Cirrus cockpit. With the Noble Flight Simulator, we can duplicate 6 different types of Cirrus aircraft (G3 SR22, G3 SR22T, G5 SR22, G5 SR22T, G6 SR22, and G6 SR22T). The Garmin Perspective panel easily swaps between the G3 and G5 configuration to the G6 configuration, so the buttons are all in the proper places.

    Having button pushing problems? The simulator is the place to practice.

    Want to experience actual emergencies? An engine failure is a lot less stressful in a simulator.

    Want to pull CAPS (Cirrus Airframe Parachute System)? The Noble Flight Simulator has a realistic CAPS handle with the same amount of pull pressure that the CAPS handle in the airplane has.

    Need an IPC or want to practice approaches? All approaches done on a Noble Flight Simulator are luggable, plus a full IPC can be accomplished.

    Want to save fuel? The Noble Flight Simulator is for you!

    To top it all off, the Noble Flight Simulator that Texas Top Aviation has is classified as an Advanced Aircraft Training Device. It is certified to the highest standards of non-motion simulators, allowing pilots working toward their private and instrument ratings to log a significant amount of time toward that certificate or rating. Up to 20 hours of IFR training is allowed to be logged in an AATD toward an instrument rating. That’s huge!

    Texas Top Aviation is also developing a CAPS specific course to expose Cirrus pilots to the many different scenarios where pulling CAPS would be necessary. This teaches Aeronautical Decision Making to Cirrus pilots who struggle with the decision of whether or not to pull CAPS. Look for CAPS course information under our Aircraft Training page later this summer.
