What low-wing airplane has passenger doors on both sides and an ultra-spacious interior that looks more like a luxury car than a spam can? AVweb's publisher test-flies the new Commander and concludes that while it won't break any speed records, it sure is a mighty comfortable travelling machine. Can you rationalize an extra 8 minutes on a 300 nm trip in order to ride in comfort and style?

Remember buying your first new car? Most people do. Like your first solo flight, it is one of those memories that stays with you. Flying a brand new Commander 114B made that same sort of impression on me.

It was new. It smelled good. The soft gray genuine leather seats along with the close pile spotless carpeting told my nose that this was a brand new airplane. The instrument panel had no scratches or paint chips, the radio bezels and lenses were clear and clean, the control wheels were smooth to the touch...and the windows had that special kind of clean that only happens when they haven't ever been cleaned.

Tall in the saddle

Outside the fit and finish were excellent, but it is the "look" of the Commander 114B that makes it unique. The wings have an unusually large amount of dihedral which position the wing tips much higher than the wing roots. Most airplanes have some dihedral, of course, but none show it off quite like the 114B.

The landing gear looks like it has been carrier rated and I knew that that trailing beam shock absorber would smooth out even less-than-perfect landings...you know, the kind pilots make when they know someone is watching.

The "right" engine

There always seems to be a "right" engine for a particular airframe. For instance, while Piper Cherokees were built with engines ranging from 140 to 235 horsepower, the 180 HP versions flew the best...at least in my opinion.

Commander 114B assembly line The single-engine Commander has flown with several engines and the current Lycoming IO-540-T4B5 rated at 260 HP feels like the right engine for this airframe. Producing just 0.48 HP per cubic inches of displacement, this engine should have no trouble reaching its full rated 2000-hour TBO.

For more performance there is a turbocharged version, the Commander 114TC which significantly increases the vertical envelope that the airplane can operate in. While the normally-aspirated 114B cruises at about 160 knots max, the 270 HP turbocharged version can do 180 knots while cruising in the high teens or low flight levels.

Kicking the tires

Preflight for the 114B is straightforward. There are five (count 'em) fuel drains, one in each wing, one in each maingear wheel well, and the gascolator near the nosewheel.

Checking the oil is done through a small door in the cowling. The new cowling is very efficient improving both the airplane's speed and the engine's cooling. But I'm afraid that with today's attention of aerodynamics and drag reduction, the days of the barn-door cowling that lets you really eyeball the powerplant during preflight (like the one on the Beech Bonanza) are a thing of the past.

The walkaround reminds you that this is a big, tall airplane. The 114B's tail rises to almost 8.5 feet, its fuselage is just under 25 feet long and its wingspan is 32 feet 9 inches. With its wide stance of 11 feet, it sits rock-solid on its gear even on the windiest of days.

Two doors, no waiting

Entering the cabin of the 114 demonstrated one of its differences immediately: Matt Goodman, Commander's Marketing vice president and my demo pilot of the day, entered through the RIGHT door while I entered through the LEFT door. There aren't too many low-wing airplanes with passenger doors on both sides.

I mentioned that with all the door problems I had seen over my years of flying that sometimes I had thought that even one door was too many. "We have the doors pretty well figured out," Matt told me. I had to admit that these doors looked like they would stay closed and fit right for some time.

A Commander pilot must make sure that both his door and the passenger door are both properly closed and locked. There are many ways to leave a door partly open, have a seatbelt flopping outside or leave a key in the lock. I've done them all over the years. With a Commander 114B, you can do it in stereo!

Startup and taxi-out

Flying the new Commander was a real treat. No rattles, very little air noise, a smooth engine, tight nosewheel steering, and crisp controls made the 114B feel like the brand new plane that it was.

Commander 114B interiorThe soft leather, dense carpet, interior appointments and metal instrument panel gave the inside a luxury feeling that complemented the solid looking exterior. Commander has gone to some effort to remove every bit of "royalite" and plastic feel from the interior of this airplane. Just sitting on the ramp it feels more like a luxury car than an light plane. And boy is it spacious!

Starting the fuel injected Lycoming is standard procedure, at least for injected Lycs: crack the throttles, mixture rich, boost pump on until fuel pressure stabilizes, then mixture to idle cutoff, crank the engine, and advance the mixture once the engine fires. Some people swear that just turning on the fuel pump and setting the mixtures rich and cranking achieves the same result: the engine will fire when the fuel air mixture in the cylinders is right. We used the standard POH approach and the engine fired right up as requested and settled into the familiar lope of a six cylinder Lycoming.

Turning on the avionics master lit up the panel showing off the Bendix/King, ah, make that AlliedSignal radio stack. Avionics included a KLN90B GPS with moving map that makes getting lost or disoriented a thing of the past.

Commander 114B panelGround control cleared us to the active and with just a little throttle the 114B started rolling and the rudder-pedel-operated nosewheel steering started us turning towards where we wanted to go. Adding some differential braking makes the steering a lot more positive at slow taxi speeds, but on the runway keeping your feet off the brakes makes things much smoother.

The fuel system is easy to manage with the fuel selector having a "both" position used for takeoff and most other times, too. There's also a "left", "right" and two "off" positions. Turning the selector to "off" requires that you push a red lockout tab. You can use the "left" or "right" positions to balance the fuel load or run a tank dry, but I expect that most Commander pilots will simply use the "both" position most of the time. The airplane has two wing tanks each holding 35 gallons of avgas (34 usable).

The straightforward fuel system is one of the many examples in the Commander 114B that indicate it is a modern design. Airplanes should not have engines stop from fuel starvation while there is still fuel in the aircraft, and having a "both" setting as the normal operating position goes a long way to protecting against this. Of course, pilots can still make mistakes, but for most operations and for most flights pilots of the 114B will not use the fuel selector very much cutting down on the possibility of mistake.

For many years I flew an airplane that only had "left" and "right" positions for fuel selection, and fuel management was something I paid a lot of attention to. The aircraft I fly today has a "both" setting and my time spent with fuel management is reduced to almost nothing.

Enough of this...let's go flying!

No flaps are needed for takeoff although the manual says that up to 20 degrees are allowed. We decided not to use flaps and after a standard run-up and cockpit check, mixtures rich and full throttle got 2700 RPMs from the Lycoming. Rotate at 70 knots, climb out at about 85 knots, then retract the landing gear.

The landing gear is powered by hydraulics supplied by an electrically driven power pack. The gear has no mechanical uplocks it is held up by hydraulic pressure so the emergency extension procedure is simply to pull the electric circuit breaker to the gear power pack and release hydraulic pressure using an emergency extension valve which will allow the gear to free-fall with the aid of downsprings.

When the gear comes up there is more noise than pitch change. Conversely, lowering of the landing gear and dropping flaps has little if any change in pitch and requires almost no trim adjustment. Another example of a modern airplane design.

After a while these small things begin to add up: The doors close snugly and securely, the airplane is quiet and devoid of air noise, the fuel system is pilot-friendly, there are no pitch changes with flaps or gear... This is one refined airplane, and I'm impressed.

Maximum performance takeoff at gross weight of 3250 pounds, according to the flight manual, requires a 1460 foot ground roll and 2600 feet to clear the mythical 50 foot obstacle at our current outside air temperature of 30 degrees Celsius and a pressure altitude of about 1000 feet. At a more standard sea level and 20 degrees Celsius the ground roll would be reduced to 1190 feet and obstacle clearance to 2090 feet.

While these are not exactly STOL figures, they ought to get you in and out of most reasonable airports without much trouble. But be sure to watch the density altitude during the summer. At 6000 feet pressure altitude and at 30 degrees Celsius we would have required 2600 feet to break ground and an astounding 7200 feet (more than a mile!) to clear the 50 foot trees. Under those conditions you might want to consider limiting the takeoff weight.

With the gear retracted and a cruise-climb power of 26" and 2600 RPM, the 114B climbed away from Oklahoma City's Will Rogers airport smoothly in the bumpy air with only minor control inputs. In the Oklahoma plains the sun heats the flat ground, even early in the day, causing the updrafts that make for moderate chop we are so used to in the summer. But with the optional air conditioning that this airplane had and the good aerodynamic manners of the 114B, even this kind of flying can be very comfortable. Leveling off at 3500 feet, we explored the airplane's manners in both clean and dirty configurations throughout its speed ranges..

Airwork

Commander 114B in flightWhile the controls were a little stiff, they were always positive and easy to keep from overcontrolling as might happen if they had any slop in them. Dutch rolls with ailerons moving from stop to stop required plenty of rudder to keep the nose on its spot on the horizon. There is plenty of adverse yaw when entering a turn. You have to keep your feet on the rudder pedals if you want coordinated turns.

At Matt's suggestion, I set up a standard-rate turn, then while maintaining the turn I slowed to approach speed, lowered flaps and gear, then cleaned up and accelerated back to cruse speed...all while holding altitude and maintaining the turn. Very easy in this airplane. Next, I tried a 360-degree steep-banked turn and hit my own propwash on the rollout. This airplane made even me look good. Then I tried some stalls and found them totally predictable and benign. The lack of bad habits and the comfort of the cockpit make this an ideal platform for anyone wishing to move into complex aircraft

We resume our climb at 850 feet per minute to reach our cruise altitude of 6000 feet and we settle down comfortably for a cross-country trip. At that altitude and the power set at 23" manifold pressure and 2400 RPM with the outside air temperature a warm 13 degrees Celsius (55 degrees Fahrenheit), the Commander 114B is getting about 69% BHP from the Lycoming up front and burning 12.4 gallons per hour. True airspeed is a by-the-book 149 Kts. Range at these settings is a solid 600+ nautical miles with IFR reserves.

Tradeoffs

We've now discovered the only weakness displayed by the 114B. It's not exactly a speed demon. Aircraft design is always a compromise. The Commander's capacious interior, good load-carrying capability and great handling come at a price: some speed is sacrificed.

Now frankly, as an Aerostar owner, I'm something of a speed freak. It is said that when Ted Smith designed the Aerostar, he set three priorities. The first was speed, the second was speed and the third was speed. Consequently, the Aerostar has a more cramped interior than other light twins, it carries less pay load, it has a small wing with a thin airfoil which takes away its short field capabilities and makes it very slippery to handle, the stalls can get exciting, and it doesn't fly slowly worth a darn...but, it goes faster than anything in its class. In the single-engine world, the Mooney is similar.

The Commander 114B is big, solid, comfortable, easy to fly, well mannered, carries a lot, looks good, but it isn't as fast as others with the same engine. But how big a deal is this? On a 300 nautical mile trip, a 10 knot penalty in cruise speed will cost about 8 minutes. Is it worth the extra 8 minutes to travel in high style and roomy comfort? Only you can decide.

Well, all good things must end, and Matt said it was time to return and land. Descending to pattern altitude, you can extend up to 20 degrees of flaps below 151 KIAS. While extending flaps BEFORE the gear is not unusual in larger airplanes, it seemed unusual in a four-place single but it does help control your speed in a rapid descent. The gear can be lowered once you're below 130 KIAS. Interestingly, once the gear is extended you can accelerate to 186 KIAS (remember to put the flaps back up first) which would give you an awesome rate of descent should it ever be needed.

The normal traffic pattern is flown at 80 to 90 KIAS, slowing to 75-80 KIAS on short final with full flaps. On my first landing attempt in the Commander, we made a positive but gentle touchdown. I couldn't tell whether it was beginner's luck or the ultra-forgiving trailing-link landing gear of the 114B.

Final thoughts

Commander 114B in flightThe Commander 114B is solid honest airplane with a spacious cabin and luxurious appointments. The engine is well suited to the airframe, the avionics complete and integrated, and the overall fit and finish shows quality workmanship. If the airplane has a weakness, it is in cruise speeds. All airplanes require compromise and this one is no exception.

Commander Aircraft wants to appeal to the corporate world. If a $30 million company can buy a business jet for $3.5 million, why can't a $3 million company buy a four place single for $300 thousand? Commander is selling the idea that a 300-400 mile trip is easily done in the 114B, very hard to drive, and sometimes impossible on the airlines. The $3.5 million jet wouldn't add much to a 300 mile trip either.

This may be a tough sell. You just don't find many four place singles in the business fleet unless the owner just happens to be a pilot. Many of us know that an airplane can be very useful for business, but that idea hasn't transferred to the non-pilots who run most small companies.

That's too bad because the Commander 114B would fit well into the corporate world. You can put four "suits" in the airplane, fly 300 miles, do your business and be home for dinner in comfort. Considering the frugal operating costs, if you do that trip with four people it will cost a whole lot less than the airlines.

But no matter how good the story gets, the industry has a lot of selling to do to get Corporate America to buy into the single-engine airplane market. Commander can't do it alone, it's going to take efforts by all the major manufacturers to legitimize the market, support by NBAA (who isn't happy unless the captain has an ATP), an effort by AOPA to support business use by small companies, and (most doubtful of all) help from the press to publicize the whole idea.

It used to be that aircraft like this sold for something less than the price of a luxury home, but no more (unless you're pricing homes in New York or San Francisco). An equipped Commander 114B will set you back about $375,000 so this isn't something to be bought on a whim. This is serious money for a serious airplane.

I would rate the second most serious problem with the 114B as the price, which is going to come under heavy competitive pressure in the future from not just Cessna, but also from upstarts Katana, Cirrus and Lancair. For now, though, none of these company's are building airplanes in the 114B's class. So if you want a classy looking and feeling airplane, head for Oklahoma City and the Will Rogers airport for a factory tour and a demo hop in this fine high-performance single-engine machine.
