When flying a WAAS GPS approach, there are several different levels of WAAS signal that a GPS receiver can get. The most precise is an LPV signal. LPV stands for Localizer Performance with Vertical guidance. An LPV approach has the lowest minimums of all the WAAS GPS approaches, typically in the range of 200-300 feet AGL. A GPS glide path (GP) is guaranteed with an LPV approach and the minimum altitude is a decision altitude (DA).
Just like a localizer, an LPV course width get’s tighter and the CDI becomes more sensitive the closer the plane get’s to the runway. Even though the LPV approach minimums are so low and the approach is down to a DA, they still aren’t considered precision approaches by the FAA (which leads to some extra planning when selecting an airport as an alternate that only has GPS approaches, since the AIM specifies only the LNAV minimum are to be considered if an alternate airport only has GPS approaches, bringing the 800 foot ceiling requirement to bear)
An LNAV/VNAV approach is still a WAAS approach that has a GPS glidepath, but is slightly different than an LPV approach. An LNAV/VNAV final approach course does not get more sensitive the closer the plane gets to the runway. The smallest course width on an LNAV/VNAV approach is 0.3 miles either side of center. LNAV/VNAV approaches will, most of the time, have higher minimums than LPV approaches and can have minimums no lower than 250′ AGL.
The third type of WAAS approach is strictly a non-precision approach with a Minimum Descent Altitude (MDA). These are designated LP approaches, which stands for Localizer Performance. These are like old school Localizer only approaches that, similar to the lateral portion of an LPV approach, the course width tightens the closer to the runway that a pilot is. There is no glide path by definition of an LP approach, though there is a caveat.
Now, by looking at an approach plate that is a WAAS approach, but only has LP minimums listed, a pilot would assume there would be no glide path. Depending on what type of GPS unit the airplane has, that pilot could be wrong. Garmin Perspective units (Cirrus G1000), all GTN 750s and GTN 650s, All G1000 NXi units, most Garmin 430W and 530W, and all Avidyne IFD 550/540 and 440 units will display an advisory glide path on an LP approach, designated LP+V.
What does LP+V indicate? An advisory glide path is just advisory, but it is totally legal to follow down on a non-precision LP approach. The kicker is obstacle clearance is not guaranteed and the pilot needs to keep an eye on minimum altitudes at the different waypoints on the approach. The big thing I tell people is, when you arrive at the MDA and the runway is in sight, following the advisory glide path below the MDA could get you in trouble with obstacles. Don’t just hone in on your instruments when you break out of the clouds. Look out the windscreen and make sure you won’t hit anything.
If you arrive at the MDA on the advisory glide path and the runway isn’t in sight, DON’T GO BELOW THE MDA! Most autopilots won’t level off at the MDA, even if that altitude is set in the altitude pre-select, so this will involve turning off the autopilot before the MDA and manually leveling off, or engaging the altitude mode of your autopilot at the MDA.
One other type of GPS approach that you will encounter is an LNAV approach. This is a non-WAAS approach down to an MDA, but your GPS unit may still give you a +V. Most modern ones will.
Mooney announced last week the redesign of their current Ovation and Acclaim models. The biggest change that Mooney pilots will love is the addition of a pilot’s door, allowing the pilot to enter on the left side instead of having to crawl over the passenger seat.
Other upgrades include a keypad for easier data entry on the G1000 and an all in one, digital standby instrument that includes attitude, airspeed, and altitude.
This raises the question, will Piper and Beechcraft follow suit?

The Pilatus Jet, the PC-24 Super Versatile Jet, is nearing certification. Pilatus expects the Pilatus Jet to receive European and US certification by December. The first delivery may even take place before the end of the year.
In developing the PC-24 Pilatus Jet, Pilatus, based in Switzerland, has taken the same approach as they did with the PC-12, their insanely successful single engine turboprop. Versatility is the key, with their mindset being to make the PC-24 Pilatus Jet the first flying Suburban jet. Pilatus emphasized STOL and unimproved strip operation in their design.
The huge cargo door so familiar on the PC-12 has been crafted into the PC-24 Pilatus Jet giving access to a massive cargo area. According to Pilatus’ website, the jet has a takeoff distance of only 2,690 feet, which is unheard of for a a business jet. There is seating for 11 + a pilot (yep, it’s a single pilot airplane!), so the whole family can come along. With a max cruise of 425 knots and a range of almost 2,000 miles, it’s a get somewhere airplane.
The price tag for a new PC-24 Pilatus Jet will be $8.9 million, which is just under what a new Phenom 300 costs. There is a 90 order wait list, so if you get on it now, you can get one faster than a Cirrus Vision Jet!

The AOPA Air Safety Institute is making it’s annual loop through Texas this January. The topic for this Safety Seminar is “More Difficult Decisions: Choices & Consequences.”
The seminar is geared our the decision making process that we as pilots face on each flight. Some decisions are easy (what altitude should I pick?) while some have much greater consequences and should be taken very seriously.
This event will be interactive for the participants as several scenarios will be presented. The goal is to help pilots learn to think through each decision, weighing the consequences along the weigh to arrive at the safest outcome of the flight.
The first area seminar will be held on Tuesday, January 21st at the Stinson Field Airport (KSSF, 8535 Mission Road, San Antonio, TX 78214). The second area seminar will be held on Wednesday, January 22nd at the TXDOT office in Austin (200 E. Riverside Dr., Austin, TX 78704). WINGs credit is available for all attendees.

The long anticipated certification of the Cirrus Vision Jet finally happened. On October 30th, the FAA awarded certification to Cirrus’ single engine jet. Marketed as the world’s first single engine personal jet, the Cirrus Vision Jet will seat five adults, two children, and cruise around 300 knots.
The Williams FJ33-5A Turbo Fan engine is operated by a FADEC, single handle throttle, similar to the throttle in the piston powered Cirrus family. In fact, the SR series was taken into consideration when designing the Cirrus Vision Jet in order to simplify the upgrade for pilots. Many of the buttons and knobs are in the same places in the Cirrus Vision Jet.
The Cirrus Vision Jet is equipped with the Cirrus Perspective Touch by Garmin that is very similar to the Cirrus Perspective by Garmin in the piston powered line. Equipped also with the Flight Into Known Icing system and the Cirrus Airframe Parachute System (CAPS), both of which are standard.
Unlike the piston powered Cirrus lines, the CAPS system on the Cirrus Vision Jet is actually mounted in the nose. Also, unlike the piston lines, the jet CAPS is integrated with the aircraft avionics to slow the airplane to between 67 and 160 knots when the system is activated. In the jet, the CAPS system was designed to withstand higher weights, higher speeds and higher altitudes.
Cirrus hopes to start deliveries of the Vision Jet by the end of the year, with many more rolling off the line in 2017. All Cirrus Vision Jet pilots will need to be type rated in order to fly the aircraft. Cirrus is doing all the type rating training in house at their new Vision Center in Knoxville, Tennessee.

If you’ve ever been to Nantucket Airport during the summer, you’ll understand when I say that it is a crazy place. During the summer months, especially on weekends, the airport is visited by an endless parade of airplanes ranging from the smallest GA airplanes to the biggest private jets.
One sunny Sunday afternoon I was standing in line at the front desk of the Nantucket FBO when the ramp door opened and a very grumpy and entitled man walked in. The man marched right up to the front desk and barked a fuel order at the girl working there, which she mistakenly read back wrong. After yelling at her for her wrongdoing, he announced that he had flown in to go to the restaurant and stormed off to drown his sorrows in fish and chips. Although he was a jerk, his attitude got me thinking about FBO’s and everything that the people who work at them do for us pilots.
For anyone who may not know, FBO stands for Fixed Base Operator. FBO’s can be found at airports everywhere and their business is to provide services such as fuel, hangar space, and tie downs. Bigger FBO’s can offer more services including rental cars, food, maintenance, flight instruction, etc. FBO workers have the ability to make life really good or really miserable for pilots, and, it seems to me, we pilots have the same power over them. Based on my personal experiences and the experiences of some friends who have worked at airports around the country, here are some things to think about next time you taxi onto an FBO ramp.

I’ve divided this article into two sections:
FBO Etiquette: What can we as pilots do to make life easier for the workers at the FBOs
FBO Pilot Perks: Ways that FBOs can help make a pilot’s life better (besides basic services like fueling)
FBO Etiquette
Be Polite
Everyone I talked to about their time working at an FBO said that simply by being friendly and polite is one of the biggest ways we can help. Most of the people that work at the FBOs love aviation and likely are working there to be around the industry in hopes of eventually being more involved. The girl working the desk at Nantucket didn’t deserve to be yelled at just for reading a tail number back wrong; don’t forget that “please” and “thank you” are still magic words.
Call Ahead
Whether you are flying to the airport, or you left your airplane at the FBO and you need them to pull it out or fuel it, calling ahead is greatly appreciated. Most FBO’s have a radio at the front desk and have their frequency listed online and in foreflight. Call ahead and tell them that you’re coming, when you’ll be arriving, and what you’ll need when you get there (gas, rental car, taxi..etc). That way they wont feel rushed and you may get what you’re looking for more expediently upon arrival.
Fuel orders
If your fuel order is difficult or confusing (example: 6.54 gallons in the right side and 4.32 in the left) you may be better off just to do it yourself at the self serve. One of the guys I talked to said that he would have pilots ask for extremely specific numbers and then stand there watching, ready to pounce when it wasn’t fueled exactly right. Its also worth noting that fuelers do make mistakes. Its highly recommended to watch and make sure that the correct truck (Jet A or 100LL) is the one pulling up to dispense your gas. Make sure you check that the fuel caps are properly installed before departing.
Look outside
A lineman motions for the pilot to stop.
Taxiing onto the ramp is not the right time to be doing your after landing and shutdown checklists. Wait until the airplane is stopped before taking your eyes off the person marshaling you to your parking spot. I’ve been told that it isn’t uncommon for a pilot to be looking inside while taxiing and it makes the linemen very nervous as they are motioning to the pilot to stop (For those unfamiliar, with lineman hand signals, here’s a helpful link).
Brakes
Unless you have talked to them and get the okay, don’t leave the parking brake on when leaving your airplane at an FBO. Often the lineman will direct you to park upfront to make loading and unloading easy, but if you’re going to stay for a long period, the airplane will need to be towed and parked out of the way. Leaving the parking brake on can make serious headaches for the people trying to organize the ramp after you leave.
Lights
Don’t blind the poor guy parking you by leaving all your landing, taxi, and recognition lights on as you’re pulling into your spot at night. Likewise, when you are ready to leave your parking space, its courteous to signal the person waiting in front of your airplane by flashing one of your lights at them so they know you are ready to be directed off of the ramp.
FBO Pilot Perks
Good parking
This one is pretty basic. I’ve heard through the grapevine that you may get parked in the boondocks as punishment for being rude to the FBO staff. However, if asked, much of the time they can pull your airplane right up front and may even let you pull a vehicle onto the ramp to load people and bags more easily.
Cheaper hotel rooms/ rental cars
Some FBO’s have special rates with hotel and rental car companies around in the area. Although it varies from place to place, you may be surprised with the amount you can save on these travel essentials. I had a flight last week where I called and was given a quote of 185 dollars for a rental car…after telling them that I was parking at the local FBO, I got the special price of 125. Check with the FBO you will be stopping at for any of their current offerings.
Fuel discounts
Sometimes the price of fuel or the minimum uptake to waive the fees can be negotiated. Sometimes, the fees may be forgotten entirely. If you are unable to take the minimum amount of fuel to waive the landing or ramp charges, tell them what you can take and you may be pleasantly surprised with the response. Its not uncommon with our Bonanza that even though the “minimum” may be 20, I can waive the fees by up-taking 10 or 12 gallons instead.
Points/ Rewards cards
Some FBO’s offer incentives to pilots for buying gas. Many of the rewards programs are free to sign up for and will pay the fuel purchaser cash based on how much fuel they buy over a specified time period. I am a member of the Avtrip program which rewards fuel purchases at Avfuel airports with points that are redeemable for money. Avtrip is just one example of an FBO fuel rewards program; if you fly regularly, it may be worth looking into whether or not there is a fuel rewards program you can take advantage of.
Crew Cars
Most FBO’s have cars designated for use by the pilots. They are extremely nice for going to get lunch or taking care of whatever short errands you may need to run around town. Most crew cars are limited to about 1-2 hours of use, but they can often be loaned out longer based on the discretion of the people working the desk. On a few occasions, I’ve had the cars loaned to me for longer, even over night, by the nice people at the FBO (They always appreciate pilots splashing a few gallons of auto gas into the cars while they are out, too).
FBOs and the services that they provide are invaluable to pilots, both commercial and private. If we as pilots are willing to work with the linemen and service reps we can make both our lives and their lives easier. Remember to be polite and don’t be afraid to ask if you need something….that’s what they’re there for!

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.
