Synthetic Vision Technology

Let’s say you’re flying in the mountains of Colorado on a cloudy day.  There’s a solid layer from the surface all the way up to 14,000 feet.  You’re inbound to Eagle (KEGE) on the RNAV (GPS) D approach.  There are mountains next to you and below you, but you aren’t concerned since you can see them all.  The base of the last reported overcast layer was 3,000 feet, so you know you’ll break out before the MDA and land no problem.

At 11,100 over AWACC, you clearly see the top of the mountain below you.  You are comfortably above it. You already have the runway in sight as well.  You pop out of the clouds on the approach at 9,700 feet, spot the airport and follow the tower’s instructions to circle north of the runway for a left base for runway 7.

How could you see the mountains inside the clouds?  You have Synthetic Vision installed on your glass panel, that’s how.

Synthetic Vision, which has actually been around since the ’70s when NASA and the US Military first developed it, was first FAA certified for the Gulfstream PlaneView flight deck in 2009.  Garmin, Avidyne, and Aspen are the main general aviation manufacturers of synthetic vision these days.  All Garmin PFDs are now equipped with Synthetic Vision while Aspen gives you the option to upgrade to Synthetic Vision when you get one of their PFDs installed.  Avidyne gives you Synthetic Vision in their R9 upgrade for the Cirrus.

What is Synthetic Vision?  Basically, it’s a 3-D picture on the primary flight display showing terrain, obstacles, traffic, and runways.  It greatly enhances situation awareness in areas of terrain or high obstacles during IFR conditions or at night.

The goal behind the development of Synthetic Vision was to decrease the amount of controlled flight into terrain (CFIT) accidents.  A CFIT accident consists of a perfectly airworthy airplane flown by a pilot (or autopilot) unintentionally into terrain. These accidents can happen in low visibility conditions or at night, but the reason is mainly due to the pilot losing track of his position in relation to obstacles or terrain (or water as was the case with JFK Jr.).

With Synthetic Vision, the goal is to enhance pilot knowledge of what is around the airplane at all times. When you’re at altitude, the terrain below you looks flat.  When you start descending down amongst the rocks, the hills or mountains start to rise up on your screen.  For those used to the coloration with the 2-D terrain feature on a GPS unit, it translates very easily to the terrain coloration on a Synthetic Vision equipped PFD. Terrain that is between 100 and 500 feet below the aircraft is shown as yellow, while terrain closer than 100 feet is depicted as red.

One neat feature on Garmin units is the Highway in the Sky.  When a pilot puts a course or a flight plan in the GPS, the PFD displays magenta boxes at the altitude selected displaying the route.  It’s handy when hand flying to just “fly through the boxes.”  They also display descent angles on approaches.

Synthetic Vision is still optional on Garmin and Aspen units, but I highly recommend springing for it.  It will give you a higher level of safety and keep you out of the rocks.

  • Flying the RDD LX7

    I get to fly a lot of different airplanes in my chosen career. There aren’t many airplanes that I take off in, then say “Wow,” and have a big smile on my face. The RDD LX7 was definitely one of those.

    I wrote about the RDD LX7 in the past, bragging about everything I read about it. The blogs all advertised 250 KTAS and 17 GPH and FL250, all of which are eye popping numbers.

    Lo and behold, those numbers are true.

    I got to go up to RDD’s Redmond, Oregon facility in April 2021 to get my initial training in the RDD LX7 and I couldn’t wipe the smile off my face. The 3 screen G3X Touch layout is very impressive and not crowded like I thought it would be. Being familiar with the G500TXi, there are some G3X specifics that take a little getting used to, but overall, it’s a good system. The main GPS and number 1 radio is a GTN 750Xi.

    We took off from RDM and proceeded to climb at 140 KIAS, which equated to 2,000 FPM. We only had half tanks (which is still 90 gallons of fuel!), but it climbed with no problem. It’s extremely responsive as I learned while doing the basic flight maneuvers. The stall speed of the airplane (the biggest problem with the Lancair 4P, the airframe that the RDD LX7 is derived from, was the terrible wing design and extremely high stall speed), was in the low 60s or high 50s, with the stall being extremely docile.

    The airplane handled very similarly to a Columbia 400, but seemed even more responsive. The glide ratio isn’t as good as some, but it’s still better than a Cirrus (plus it still has a BRS system to boot).

    The big test was the flight to San Antonio from Redmond to bring the plane home. The new owner and I departed RDM with the tanks full of Avgas (180 gallons), then got up to a cruise altitude of FL210. After setting power and leaning, the numbers came out true to spec: 252 KTAS, 17.5 GPH.

    The greatest part? We stopped in Santa Fe to stretch our legs and we didn’t need fuel. We still had 100 gallons left! That left us plenty to get to San Antonio with 40-50 gallons left over. Another RDD LX7 owner flew his piston direct from Redmond, OR to Jacksonville, FL, non-stop. It was over 9 hours. That’s impressive.

    You can’t beat the purchase price, either. A new Cirrus SR22T runs a little north of $1.2m. A piston engine LX7, that is pressurized, 70 KTAS faster with a much longer range, and still has a BRS, is between $850,000-$900,000. An LX7 starts to make a whole lot of sense when you weigh all that. There is also a PT6 option with several different sizes and horsepowers to choose from, which costs more, but you see 300 KTAS.

  • Present Position Hold

    When I was working on my instrument rating back in 2007, my instructor and I did a lot of unpublished holds.  In ground school, I heard a lot about holding for weather or holding due to a traffic delay.  At my first job, my chief flight instructor was also a Continental (now United) captain and he told me a lot about having to hold for weather going into different places.

    I heard all this, but I figured it would never happen to me when I’m flying GA airplanes.

    Boy was I wrong!

    I was flying a Piper Malibu into Phoenix with two passengers for Super Bowl weekend and the weather was awful.  No thunderstorms, but moderate precipitation and low ceilings.  We were coming into Deer Valley (KDVT) on the north side of Phoenix and about an hour out, ATC advised me that arrivals into DVT were having to hold and to expect a delay.  The controller said the delay would be about 30 minutes, so by doing a quick calculation, I determined the delay would probably be all cleared up by the time I got in the area.  At the time, I didn’t know if the delay was due to weather or traffic congestion.

    Twenty minutes later, the controller advised me that there was still a delay.  I queried what it was for and he informed me it was due to weather.  He asked me if I wanted to hold or divert.  I listened to the ATIS and heard the ceilings were variable from just below the minimums to just above.  I told him I would hold as the TAF I saw predicted the ceilings to go up.

    “Malibu, hold present position, hold east, expect further clearance 2140 Zulu.”  Gulp.

    At this point, my autopilot had gone out, it was turbulent and I was definitely in the soup.  This was going to be fun.

    After recovering my wits, I read back the clearance, then set about setting up this hold without getting too far from my present position.  The Malibu I was flying had a Garmin 530 which I was using as my primary means of navigation.  I was on V190, but I didn’t have all the fixes in my flight plan.  What to do?  And what to do fast?

    The 530 has a rarely used function called a User Waypoint.  It comes in handy in situations like these.  On the moving map, you can turn the cursor on, move the cursor to any point on the map, and, by pressing enter, create a User Waypoint.  This is what I did on V190.  After I created it, I had to go to my flight plan, find the right spot, and input the User Waypoint just like I would any fix.  Just a note here, when you create a User Waypoint, make sure you remember what you named it so you can find it again.

    After I input the User Waypoint in the flight plan, I had to go back and activate the leg that the User Waypoint was the end point on.  Then, to make sure the flight plan didn’t go to the next waypoint once I crossed my User Waypoint, I had to press the OBS button on the 530 in order to put the GPS in suspend mode.

    Keep in mind, my autopilot wasn’t working, so this involved a lot of multi-tasking!

    That’s how to do a present position hold using the Garmin 530.  Got all that?  Here’s a concise review:

    • Create a User Waypoint
      • Turn the cursor on by pressing the FMS knob
      • Move the cursor to the point where you want your User Waypoint
      • Press enter and name the User Waypoint
    • Press the Flight Plan button
    • Input the User Waypoint into your flight plan at the proper point
    • Activate the leg that the User Waypoint is the end point on
    • Finally, press the OBS button to put the GPS in suspend mode
    • After you’re cleared onward, just press the OBS button again to take the GPS out of suspend mode

  • Beware of the Lunch Monster

    He prowls around, preying on innocent pilots.

    He’s very sneaky, creeping unexpectedly and attacking after the propeller begins to turn.

    He’s very cunning, veiling his intentions until, BOOM, he attacks.

    Beware of the Lunch Monster!

    Whenever I am doing a full day of training (which is usually how transition training courses are planned out, in full day sessions), I always plan a lunch stop.  My metabolism has the speed of a rocket ship, so I get hungry and need some sustenance in the middle of the day.  I have a running list of airports to stop at that have good lunch spots at them or nearby, so my customers and I usually end up at one of those airports.

    Almost without fail, if a customer is having an excellent flying morning, nailing all the procedures, picking up all the techniques, and overall, flying pretty well, then eats lunch, the afternoon doesn’t go quite as well.  Doing some of the same things we did that morning, but the customer’s performance isn’t quite as good.  Most of the time, it’s just a brain lockup or landings aren’t quite as squeaky as they were in the morning.

    Part of it is fatigue after flying for 2-3 hours in the morning.  The other part is what I call the Lunch Monster.  Eating a big lunch can sap away brain power and cause a person to lose energy around 2-3pm, leading to an afternoon lull (or the Lunch Monster attacking!).

    According to Forbes.com:

    Diet contributes to energy levels too. “Eating a lunch that is too big is the most common reason for feeling sleepy in the afternoon,” says Rebecca Solomon a nutritionist at Mount Sinai Hospital in Manhattan. “All your energy goes into digesting the enormous meal.”

    The goal is to keep the body’s Cortical and Cortisone levels even since they’re the hormones released by the body in reaction to stress–they produce the fight or flight response. Their levels are elevated when you have sugar, caffeine and processed food, so you feel awake and energetic. But a few hours later, when those levels drop, you’re sluggish.

    Solomon recommends eating a meal that’s balanced with healthy fats (from olive oil or avocados, for instance) with protein and healthy carbohydrates (whole wheat bread or pasta). The portion will vary for people of different sizes, but a general rule is you should be hungry about four hours after the meal.

    Another healthy eating habit: Consume small portions of foods throughout the day, including almonds, carrots and hummus and fruit. Enjoy lunch around 1:30 or 2 p.m., just before the time you normally feel fatigued.

    Now, most of the stops on my list of restaurants don’t fit the bill of healthy fats and healthy carbohydrates (plenty of protein, though, especially the BBQ joints).  For those days, bringing along a snack like almonds or dried fruit is a great idea to munch on mid-afternoon.  Trimming down the amount eaten at lunch helps a lot too.

    So, the next time you have a long day of flying or training, beware the lunch monster and prep some good snacks when your flight instructor says you’re stopping for BBQ!

  • The Importance of Transition Training

    In September, the FAASTeam at the San Antonio FSDO put a special emphasis on transition training (AOPA put out a free course last year covering general transition training topics).  A lot of pilots don’t understand the need for transition training or what it even entails.

    Transition training deals mainly with piston engine aircraft, regardless of whether the airplane is a single or twin.  The FAA doesn’t have any special requirements for changing from one piston engine airplane to another, as long as the pilot has the appropriate endorsements (high performance, complex, high altitude, etc.) and is rated in that category and class.

    Transition training is promoted mostly by insurance companies. An insurance company looks at a pilots experience when deciding to insure him or her in a new airplane.  If the pilot has only flown Cherokees and Comanches and is now upgrading to a Malibu, then the insurance company is going to require some transition training with a knowledgable instructor.

    What is transition training?  It is when an appropriate rated pilot needs to learn how to fly a different airplane.  These are referred to commonly as checkouts, but with more complicated airplanes, the training is actually very in depth.

    Using the example above, Pilot A just sold his Comanche 260 and bought a 1987 Malibu.  Pilot A says, “A Malibu is a complex, high performance, single engine piston, which is what I had in my Comanche.  I can fly that, no problem.”  In reality, a Malibu has a lot of differences.

    pa46-transition-training

    First, there are more systems in a Malibu.  You have pressurization, air conditioning, emergency oxygen, turbo charging, and possibly radar.  Not to mention you are dealing with a Continental engine instead of a Lycoming.  And, is it a factory TSIO 520 or a converted 550?  2, 3, or 4 blade prop?  Glass panel or steam gauges?  What kind of autopilot?  Plus, it’s a much heavier airplane so it’s going to fly different, have different rotation and landing speeds and handle differently in stalls.  What’s the sight picture supposed to be on final approach?  What are the emergency procedures?

    Overwhelmed yet?

    An experienced, insurance approved instructor and training program is a necessity when getting into new airplanes.  It makes for safe pilots and safer skies.

    Texas Top Aviation offers Cirrus Transition Training as well as Bonanza Transition Training and Columbia/Corvalis Transition Training.  We are working on an insurance approved Piper PA 46 piston transition course as well (Malibu and Mirage) and will have the course approved by the end of 2016.  Contact us today to schedule your transition training.

  • Night Flying

    Ah, fall is finally here.  In Texas, it arrived about a month late, but showed up with a vengeance.  A strong cold front caused a 40 degree temperature drop in 12 hours earlier this week, bringing rain, lower freezing levels, and lots of wind.

    Fall means cooler temps, but fall also means less light.  The sun begins to set sooner, plus the fall back time change in November cause darkness to spring upon an unaware pilot.

    Before getting in to too many night landings tips, just a friendly reminder, passengers can only be carried at night if the PIC has completed 3 takeoffs and landings to a full stop in the last 90 days during the time period of 1 hour after sunset to 1 hour before sunrise.

    Lots of us have been landing long before sunset for most of the past couple of months, so those night flying skills might be a little rusty.  The best way to remedy night flying rustiness?  Call an instructor and go get some practice.

    In the meantime, here are some tips as to what to expect for your next night flying experience.

    1. Your Eyes Are Very Important.  This may seem like an obvious statement, but night vision can be affected by many things.  Before you takeoff, you want to make sure you can see in the dark.  The FAA recommends no bright lights 30 minutes prior to takeoff.  They also recommend using oxygen at night as this greatly improves night vision, even at low altitudes.  Use off center viewing to help spot traffic or other objects in the air.  Finally, when preflighting, use a red flashlight as much as possible, but if you do have to use a white light, close one eye to keep one eye from being blinded.
    2. Utilize Approach Lights on Landing.  Night landings are very different then day landings.  It is very difficult to get the proper depth perception, not too mention see obstacles below you on your final approach to a runway.  PAPI’s, VASI’s, and instrument approach glide slope’s become very important.  If you are VFR only pilot, if your airport has a PAPI or a VASI, keep 2 white and 2 red (or 1 white and 1 red) lights.  If you see 3 red (or 2 red), climb.  If you see 4 red, definitely climb.  If you are an IFR pilot, I highly recommend always flying an approach at night.  What if your airport doesn’t have a PAPI, VASI, or approach with a glide slope?  You might not want to utilize it at night.  One side note on VFR flight: Clouds are nearly invisible at night.  If you do fly into a cloud (a clue is your strobe lights start reflecting back at you), don’t panic.  If you have an autopilot, turn it on and execute a 180 degree level turn.  If you don’t have an autopilot, start scanning your instruments, keep your attitude indicator blue side up, and make a shallow 180 degree while maintaining altitude.  Then call ATC, advise them what happened, and ask for help.  One more note:  I highly recommend that if a pilot finds that he/she will fly at night at lot, get an instrument rating and fly IFR at night.  It’s much safer.
    3. Practice Landings Before Carrying Passengers.  The tendency when landing at night is to level off too high before flaring, causing the airplane to bleed off speed and energy too high above the runway.  This can lead to a stall, a hard landing, and/or too high of a pitch attitude at touch down causing a tail strike. A good tip is start your level off when you can see the tire marks on the runway.  Make sure you practice night landings, preferably with an experienced instructor who is night current and proficient, before carrying any passengers on board, even if you are night current, but haven’t landed at night in a while.
    4. Night Emergencies.  For engine failures at night, you are very limited on options.  Unless you have a Cirrus equipped with a CAPS parachute system, you really have two options if an airport isn’t within gliding distance.  Find a wide, lighted road that appears to be lightly trafficked.  A word of caution, though:  be careful of light poles, fences, concrete medians, cars, and buildings.  The LA freeway would not be a good option (though there are exceptions to this rule as is evidenced by the picture below).  The second option is find a dark spot and pray it’s a field (or the Hudson River).  As you get closer, you can turn your landing light on to see what the ground looks like.  If it looks good, keep the light on and continue.  If you don’t like what you see, turn your landing light off and continue….

    Flying at night can be the best time of day to fly.  It’s usually smoother, cooler, and you get to see all the city lights.  It is a very different environment, however, so make sure to get some training before darkness settles in on your next trip.

    Ah, fall is finally here.  In Texas, it arrived about a month late, but showed up with a vengeance.  A strong cold front caused a 40 degree temperature drop in 12 hours earlier this week, bringing rain, lower freezing levels, and lots of wind.

  • 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.
