SPC099 [BR] The Starting Gun — What MOSAIC Means for Student Pilots
MOSAIC took effect right in the middle of Oshkosh this year. A few months later, here’s what actually showed up, what it costs, and what it means if you’re learning to fly.
This is my AirVenture 2026 industry report, the one I promised you back in Episode 94. I look at two big stories through one lens: what do they mean for a student pilot, for someone thinking about getting started, or for a pilot who wants a more affordable airplane?
We walk through the first MOSAIC trainers from Van’s, Sling, Pipistrel and others, and how their purchase prices and fuel burn compare with a new 172 or Archer. I also get into what the new rules really unlocked, including flying in actual clouds, and why sport pilot is now a much more useful starting point. On the panel side, it’s Garmin AXIS, Dynon and a bold little startup called Airhart.
I also share a caution about technology and good pilots, why you shouldn’t wait for new airplanes to start training, and my hope for where MOSAIC takes this industry over the next five years.

Two days before AirVenture, the engine in my Jabiru went
Bill:quiet over southeastern Colorado, and I had to put it in a field.
Bill:Two days later, I'm standing on the grounds at Oshkosh, and Jabiru's big
Bill:debut is an airplane with two engines.
Bill:I climbed inside.
Bill:It looks just like mine, just with a spare.
Bill:So let's talk about what showed up at Oshkosh this year and what it
Bill:means if you're learning to fly in episode 99 of the Student Pilot Cast
Bill:Welcome back to the Student Pilot Cast.
Bill:I'm Bill.
Bill:Back in episode 94, I promised this one was next.
Bill:That was four episodes ago.
Bill:In my defense, a listener asked a question, and I went and recorded a
Bill:flight with six recorders running.
Bill:This one's a lot simpler, I promise.
Bill:dustry report from AirVenture:Bill:A few months later, which actually kind of helps because now we can see what's real.
Bill:Two big stories, MOSAIC, the FAA's new light sport rule from the
Bill:manufacturer's perspective, which took effect right in the middle of
Bill:the show, and a wave of new avionics.
Bill:And I'm gonna look at both through one lens.
Bill:What does that mean for a student pilot or for somebody thinking about getting into
Bill:flying, or maybe even a pilot looking to own their own more affordable airplane?
Bill:Quick background.
Bill:MOSAIC is the FAA's rewrite of the light sport rules.
Bill:It came in two phases.
Bill:The pilot side took effect in October of last year.
Bill:The aircraft side, the part that lets manufacturers build and certify bigger,
Bill:more capable light sport airplanes than they could before, took effect July 24th.
Bill:That was Friday of the week of Oshkosh
Bill:So the show didn't just cover MOSAIC, the show was the starting gun for what
Bill:hopefully becomes a race of innovation.
Bill:Van's Aircraft delivered the very first airplane certified
Bill:under the new rules, an RV-12iS.
Bill:It went straight to a flight school, Crystal Air Academy in Chattanooga.
Bill:Sling announced the 2M, a MOSAIC version of their trainer, and
Bill:started deliveries in August.
Bill:Pipistrel, which is owned by Textron, showed the Voyager, a two-seat
Bill:trainer built for flight schools with deliveries, I think, starting next year.
Bill:Vashon showed a training version of the Ranger, and Zenith showed
Bill:a new three-seat Super Cruzer.
Bill:And yes, the twins.
Bill:Jabiru's J432 is two engines on a design that's basically my airplane.
Bill:They've had it ready and waiting for the rule.
Bill:They've been playing around with it for a while.
Bill:Sling says it's gonna start working on a four-seat twin for Oshkosh next year.
Bill:Honestly, I was kind of hoping for a little bit more than what
Bill:we saw, but the rule took effect in the middle of the show.
Bill:What we saw were the airplanes that were already built and
Bill:waiting for the rule to exist.
Bill:Engineering programs take years.
Bill:This was just the first lap, not the whole race.
Bill:So why should a student care about a rule change?
Bill:Because MOSAIC changes the math of flight training, hopefully anyway.
Bill:Let me walk you through it.
Bill:First of all, what does it cost to buy an airplane?
Bill:A brand-new Cessna 172 today runs around a half a million dollars.
Bill:Figure about 480K base, and more like 500 and above by the
Bill:time it's equipped normally.
Bill:A new Piper Archer is in the same neighborhood, roughly 400 to 500,000
Bill:depending on how it's equipped.
Bill:Now, the new MOSAIC trainers.
Bill:The Van's RV-12 starts at about 246,000.
Bill:The Pipistrel Voyager is expected around 275, and the Sling 2M is
Bill:about 340,000, something like that.
Bill:So you're looking at roughly half to maybe two-thirds the
Bill:price of a new 172 or Archer.
Bill:That's still a lot of money, of course, but for a flight school deciding
Bill:how many airplanes it can put on the line, there's a big difference there.
Bill:You m- might say to yourself, "Self, I don't know if I'd buy
Bill:this because most of the flight schools I know don't use brand-new
Bill:aircraft." Well, that's likely true.
Bill:Some of them do, and they generally charge a premium for it, rightly so.
Bill:Many use older airplanes, and some use downright ancient airplanes.
Bill:But stick with me.
Bill:Listen to the next points as well.
Bill:So the next point is, what does it cost to run?
Bill:This is the part you actually feel in your hourly rate quite a bit.
Bill:A 172 or an Archer burns somewhere around s- eight and a half to 10
Bill:gallons an hour of 100 low lead.
Bill:These Rotax, mostly Rotax-powered MOSAIC trainers burn roughly half that,
Bill:around four to five gallons an hour, and they'd rather run on unleaded auto fuel,
Bill:which is usually cheaper than avgas.
Bill:Engine overhaul intervals are about the same on both, usually around 2,000 hours.
Bill:So same overhaul life, roughly half the fuel.
Bill:This is where a lot of costs of training come from, and this is where we compare
Bill:the cost of maintaining an older aircraft and a brand-new MOSAIC aircraft.
Bill:While the acquisition cost of an older 172 might be similar to the price of a new
Bill:light sport, or new MOSAIC, if you will, the cost of maintaining them will almost
Bill:always be cheaper on the newer one, and the operating costs in general, including
Bill:fuel costs, are going to be much lower.
Bill:Even using the ancient airplanes costing maybe half the cost of a new light
Bill:sport trainer, the maintenance costs are going to be significantly higher
Bill:on those older airplanes, and the fuel costs are still twice as high or more.
Bill:So this stuff adds up.
Bill:Now let's talk about what they can do.
Bill:This is what MOSAIC really unlocked with the new rules.
Bill:Light sport trainers have been around for years, and they were cheaper, but
Bill:they ran out of syllabus, if you will.
Bill:Before MOSAIC, a light sport airplane couldn't take you into
Bill:actual instrument conditions, and a lot of them couldn't carry two
Bill:real-sized adults with full fuel.
Bill:Now, the RV-12iS and the Sling 2M are cleared to fly in actual clouds.
Bill:The Voyager is built for IFR training.
Bill:The Sling 2M carries more than 600 pounds of useful load, which means two adults,
Bill:full fuel, and a whole airplane parachute.
Bill:That's a trainer that can take you a lot further through your training than
Bill:the light sport airplanes we had before.
Bill:I do some training in my light sport aircraft, and in fact, because it's
Bill:considered a technologically advanced aircraft, or TAA, I've done quite
Bill:a bit of commercial training in it, since TAA aircraft can replace the
Bill:required experience of complex aircraft for the commercial certificate.
Bill:If I were to invest in some more advanced navigator technology that
Bill:could do instrument approaches, I could even get somebody's instrument
Bill:rating in it, and many people do.
Bill:But I could never take a student into actual clouds during that training,
Bill:and that is a huge disadvantage in my opinion, and would make me feel weird
Bill:about doing instrument training in it.
Bill:I think you get it.
Bill:Let's talk about who can fly them.
Bill:On the pilot side, the sport pilot certificate got a lot more useful.
Bill:Now, you don't need a sport pilot certificate to use them for
Bill:training for other certificates.
Bill:But if somebody's going after a sport pilot certificate, of course,
Bill:these new MOSAIC light sport aircraft are perfect for that as well.
Bill:Since October of last year, sport pilots can fly at night with the right
Bill:training and endorsement, and they can fly a much wider range of airplanes.
Bill:You're still limited to one passenger, but for a lot of people, that makes sport
Bill:pilot a real on-ramp, a faster, cheaper first step that keeps working as you
Bill:grow into more and more capabilities.
Bill:And it's important to bring this up.
Bill:Sport pilots are no longer restricted to flying just light sport aircraft anymore.
Bill:That's what I was referring to before.
Bill:It opened up a whole new world.
Bill:The rule that went into effect last year made this possible.
Bill:It extends to so many more planes that are already out in the
Bill:GA fleet, which is incredible.
Bill:Of course, sport pilot does come with a few more restrictions, but
Bill:it has opened up incredibly far.
Bill:Now let's talk about the competition part.
Bill:This is the part I love.
Bill:Look at who's chasing flight schools now: Van's, Sling, Pipistrel, Vashon.
Bill:Cirrus has also announced a new trainer, and here's my favorite detail.
Bill:Pipistrel is owned by Textron, and Textron also owns Cessna.
Bill:So Textron is now competing with its own 172.
Bill:When the company that builds the most prolific trainer in history starts
Bill:building a cheaper alternative to it, that tells you where the market's heading.
Bill:Now the fair caveats.
Bill:These are two-seaters going up against mostly four-seaters, so it's not quite
Bill:apples to apples, although for training, two seats is what you actually use.
Bill:And most schools fly used 172s and Archers that they bought for a lot less
Bill:than new, like I mentioned earlier.
Bill:So cheaper airplanes don't automatically mean cheaper lessons tomorrow.
Bill:That, of course, depends on your school and a whole bunch of other factors.
Bill:But the schools are buying.
Bill:Van's says it's building one of these RV-12s about every four days, almost
Bill:all of them for flight schools.
Bill:And this is the first time in a long time I've seen the trend line
Bill:pointing the right way like that
Bill:The other big story at Oshkosh was in avionics, and what I loved is that
Bill:it came from both ends, the giants in the industry and the startups.
Bill:From the juggernaut, Garmin AXIS was announced right before the show, and it
Bill:was a big part of what they were showing.
Bill:One integrated system that rolls the flight display, IFR GPS, navcom, audio,
Bill:all of those things into one thing.
Bill:That's fewer boxes, simpler installs, and it has a dedicated emergency
Bill:button, which is pretty cool.
Bill:Sling and Pipistrel are both putting it in their new trainers, so a lot
Bill:of students will see this setup.
Bill:Dynon put IFR GPS right into its SkyView HDX, so following kind of
Bill:that similar let's integrate things better, which matters a lot for the
Bill:experimental and the light sport crowd.
Bill:And then there were the startups.
Bill:One pretty interesting one was a small company out of Long Beach,
Bill:California, called Airhart.
Bill:Their panel looks like one giant screen across the whole panel.
Bill:Linda Sollars had it installed in her Sling High Wing that most of you
Bill:probably know about, and I got to see that, so that was pretty cool.
Bill:It was a little rough around the edges in some ways.
Bill:It didn't look quite as polished as some of the big boys, but
Bill:it's new, and its ideas are bold.
Bill:Checklists that pop up on their own for whatever phase of flight
Bill:you're in, and ATC calls transcribed into text right on the screen.
Bill:It's hard to miss a call now, right?
Bill:Same story as the airplanes: competition.
Bill:Everybody's racing the same direction.
Bill:Simpler to fly, simpler to install, simpler to maintain.
Bill:When that happens, hopefully safety goes up and costs come down.
Bill:One caution from someone who just landed in a field without an emergency
button:a smarter panel doesn't replace knowing how to fly the airplane.
button:These tools are great at helping a pilot who knows what they're
button:doing, and that's still you.
button:All of these advancements in avionics can be a huge boon to safety, but
button:the experience and training of the pilots is more important than ever,
button:even with these advanced avionics.
button:I cringe when I see marketing in popular media that makes it seem like technology
button:can make flying more like driving.
button:The risks are way too high for this mentality, in my opinion.
button:I've got a lot more to say about this, but that's probably its own episode.
button:Just remember, high-tech panels can take some workload off of a good
button:pilot, but it's still the good pilot managing the risks and making decisions,
button:just with a lot more help and a lot more data at his or her fingertips.
button:All this tech in the hands of a lesser pilot makes the whole situation less safe
button:because of an improper understanding of risks and the distractions of data that
button:he or she doesn't know what to do with.
button:But let's move on from that for now.
button:We'll cover stuff like that hopefully in the future.
button:So what does this mean for you students and anyone thinking about starting
button:or somebody maybe just thinking about getting a newer, more capable aircraft?
button:Three points.
button:First, the airplanes you train in can get newer, cheaper to run, and more
button:capable, and cover more of your syllabus.
button:All the way through instrument training, commercial, CFI, CFII, et
button:cetera, can happen in them, and soon, probably even multi-engine training.
button:Second point, sport pilot is a real starting point, now giving
button:you access to a lot more airplanes and capabilities than before.
button:And third, don't wait.
button:Don't hold off on starting your training until the new
button:airplanes show up at your airport.
button:The fundamentals you learn in a 172 today are the same ones
button:you'll use in whatever comes next.
button:But what I am hoping is that this improves training, improves exposure to various
button:airplanes, brings more people into the industry, all while reducing cost.
button:so along those lines, I said I'd go on the record, so here it is.
button:And honestly, this is more hope than prediction.
button:I think, and I hope, that over the next five years or so, that MOSAIC
button:transforms this industry a bit.
button:Innovation up, prices down.
button:More people in the left seat in airplanes that are more modern and more accessible
button:than what most of us learned in.
button:Check back with me at Oshkosh in a few years, and we'll
button:see how the industry's doing.
button:So the short version: MOSAIC is live.
button:The first airplanes are real, and the first one went
button:straight to a flight school.
button:That puts a grin on my face.
button:The value case is real.
button:That's another point.
button:About half to two-thirds the purchase price of a 172 or Archer that's
button:new, and about half the fuel, and now the capability to carry you
button:much further through your training.
button:And the competition, from the airplanes to the panels, is what
button:pushes innovation up and prices down.
button:And for students, there's no reason to wait.
button:It's time to get started.
button:So were you at Oshkosh?
button:What did you see and think was interesting?
button:Or what do you think about MOSAIC and the changes that it might bring?
button:What does it mean to you?
button:Leave me a voicemail at studentpilotcast.com/radiocheck.
button:And if you're not on the Friday Flight Brief yet, the link's in the show notes.
button:I flew to Oshkosh this year to see the future of flying, as I always
button:do, and I ended up getting there in someone else's airplane and coming
button:home on an airline because the present quit on me over a field.
button:Both things are true.
button:The airplanes and the panels are getting better every year, and the
button:thing that got me down safely was the same thing that your instructor
button:is teaching you to do right now.
button:Still flying, still learning, and hoping MOSAIC gets here a little faster
button:than my Oshkosh industry report did
