My experience is that recent Mooneys have excellent fit and finish. What makes them seem old to people who get into them is ingress/egress compared to a Cirrus which is more car like
Ya still gotta climb on the wing, right?
How's it so different?
and the panel which is very different in appearance from a Cirrus. The Mooney panel is very flexible and allows easier avionics upgrades just like a 1960's era car is easier to make stereo upgrades on. The Cirrus looks like a modern car with all of the good and bad that brings i.e. it looks modern and designed as one unit but has less flexibility when it comes to upgrades.
I'm not sure what the difference really is, in this age of glass panels. I don't think a Cirrus is *that* hard to upgrade, that center console is pretty much standard radio-stack width. But again, in the age of glass, the upgrades to the panel often aren't physical anyway.
I wouldn't call the Cirrus upgrades minor. G1 to G2 redesigned the fuselage. G2 to G3 redesigned the wing including moving from a fiberglass to a carbon fiber wing spar. The FIKI design work was major. The G5 adds 200# of useful load and flap extension speed goes from 119 to 150. That's major. With the G5 the wing spar was redesigned again as was the chute and the gear. A G5 Cirrus is very different form a G1. I wish Mooney, Beech, Piper and Cessna had put as much effort into improving their planes. It would be a more exciting market.
Cirrus is just catching up to everyone else who's had all kinds of time to get their airplanes done right before Cirrus was born.
Mooney already has FIKI... Flap extension speed is 110 but that's OK because you've got gear you can drop at 140 that slows it down way better than flaps, and if you can't get it down to 140 there's speed brakes that you can use all the way up to Vne.
I'm glad Cirrus has continued to improve their airplanes, but the big question is: Have they turned a profit? They keep getting sold off from foreign investor group to foreign investor group it seems, and if they were making big money the groups would keep 'em. The big problem is the cost of the FAA certification process - Cirrus sells enough airplanes that they've got more money to pump into R&D than the others, but they're still not able to do that AND make the big bucks. Sad state of affairs.
Do the following to the Moony design. Add a pilot side door.
It's actually easier to get into the left seat of the Mooney than it is to get into the right seat, once you know what you're doing. Also, the oxygen system controls and cabin lighting would have to be moved somewhere.
Increase cabin width by 6 inches.
Ah, but when you do that, you slow the plane down. Mooney's hallmark is speed and efficiency, and if they let go of that, how do they set themselves apart from the rest of the crowd? I bet your 6-inch cabin width increase would cost at least 15-20 knots at the same power/fuel flow.
Add at least 200# to the useful load.
Again, while I'd love this, it'd slow the plane down somewhat - a 200# increase in useful load means >200# increase in gross weight. Now, to achieve the same climb rates, you need more horsepower, you burn more fuel, etc.
Redesign the panel making it lower for better forward visibility and make it look like a modern car. If you want to drop one of those, drop the panel redesign. I don't think these changes would be minor and I don't see Mooney ever having the resources to do them.
I don't think the height of the panel is the problem... Comparing pictures of the Acclaim (G1000) with the Cirrus (Perspective, slightly bigger screens), I don't think there's a huge difference in the space there, and Cirrus puts the backup instruments down below where Mooney puts them to the side.
I think the difference is twofold: The panel is closer to the pilot in the Mooney, which I, as a tall guy, greatly appreciate - I can have the seat in a comfortable position with tons of legroom (another Mooney strong point, Al Mooney was 6'5") but still reach things on the panel without needing to lean forward. The second is that the plane sits at a +5º pitch angle when it's on the ground and has a much longer nose than the Cirrus (remember all that legroom, and the need to stuff a nose gear up in there too) so it is somewhat difficult to see over the nose on the ground.
Again, all of the above are possible, but they are all engineering tradeoffs. If you make the Mooney into a Cirrus, then *Nobody* will have a reason to buy one. Mooneys get sold to the pilots who want more speed and efficiency, want to be able to control their engine (IE RPM) themselves, who are tall and want a ton of legroom, etc.
There is definitely a place for Mooney. It is a pilot's plane with excellent performance and a strong airframe and it looks great sitting on the ramp. The problem is that, in it's present form, it can never grab a majority of single engine sales.
I don't think the main difference between the Mooney and Cirrus (or Corvallis and Cirrus, or just about anyone and Cirrus) is the airplane. Cirrus makes a fine airplane, that's for sure - But their marketing is orders of magnitude better than everyone else's. I wish some of the other companies would follow their lead here and market to non-pilots (*especially* Cessna) and grow the community, rather than simply preaching to the choir the way they do. If Mooney had Cirrus' marketing department and Cirrus had Mooney's, I believe you'd see a near complete reversal in their respective fortunes.
Considering the low total of single engine planes being sold, that's a huge problem.
Not really. NOBODY, even Cirrus, holds a majority of single-engine sales. The latest numbers I have put Cessna at 40.8% of the piston single market share, Cirrus at 29.9%, Diamond at 12.5%, Piper at 5.5%, Beech at 4.0%, and the rest trailing at ever more insignificant numbers.
