The AV-20 fits into a standard 2.25-inch clock hole. This instrument is available in two versions, the AV-20 at $499 and the AV-20-S at $895. The difference? The AV-20-S has pitot/static input so it can display real airspeed, not GPS-derived groundspeed and it also functions as a capable attitude gyro. The entry-level AV-20 lacks the plumbing input and has no gyro, but it has multilevel clock and timer functions. Both are approved for installation under the FAA’s NORSEE rule-non-required safety enhancing equipment. Technically, that means it can’t replace a panel clock if the airplane requires one, nor can it provide a legal attitude source backup if one of those is needed.

Recall that German-based Flight Design had its own four-place airplane, the C4, in the works until it ran into financial trouble. At Aero, the reorganized company announced a rethink of the CTLS line and a new four-place project called the F4. The latter will be a CS 23-certified aircraft that’s essentially a stretched version of the CTLS. Predictably, the powerplant will be Rotax’s new 915 iS. Gross weight is set at 2420 pounds with performance in the 150- to 160-knot range. The price target is under $300,000.

HUDs are simple in concept, but not so simple to engineer and install. They’re basically an optical projector that displays an informationally compressed flight data display on a glass screen called a combiner. The idea is that the pilot can look through the display and see critical data such as attitude and airspeed while avoiding the distraction of looking down at the panel. The display has to be engineered in such a way that the data appears almost at infinity, so as to be an aid, not a distraction.

At the Aircraft Electronics Association show in Palm Springs, Garmin unwrapped the GPS 175, an old-school standalone IFR navigator with LPV approach capability and a companion product that’s something we weren’t sure was even possible, never mind that anyone would want. The GNX 375 combines the standalone GPS navigator with ADS-B In and Out in the form of a Mode-S transponder. It’s essentially Garmin’s hot-selling GTX 345 1090ES transponder mashed together with the navigator. Neither of these units have comm capability, however, so they’re not a straight-up replacement for the GTN-series mapcomms nor a new-age GNS 430/530.

A quarter century later, it’s fair to ask: Well, was it? The easy answer is yes, it was and is. But with a host of safety features such as crashworthy seats, energy absorbing structure, cabin flail space and the first-ever certificated airplane ballistic recovery parachute, Cirrus also implied that its new airplane would be safer, without actually saying the safest ever. So, how about that? Has it delivered on those claims? Answering that is not as simple as crunching the GAMA numbers to enumerate Cirrus’ inarguable dominant market share. But with a quarter century of accident data to review, it’s reasonable to take a stab at it.

This economy of scale has put upward pressure on volume, downward pressure on pricing and competitive pressure to improve LED efficiency and longevity. In new aircraft, LED landing lights are all but standard, as are LED position and and strobe lights. The aftermarket remains a mixed bag. A survey of any ramp will find a smattering of LEDs, but a bunch of old GE 4509s. That the retrofit market is small is indicated by the small number of players-about six. As we went to press in February, that dropped by one when Whelen announced that it acquired LoPresti Aviation’s entire line, including the recently formed Illumivation for LED products. The new combined entity is called Whelen Aerospace Technologies. Most of these companies have some tilt toward large commercial and military applications because, well, that’s where the profit is.

The reaction was swift and not all positive. Later in the same week, EAA walked back the comment to clarify that Pelton should have said the FAA had agreed to consider an NPRM and actually the rule was at least two to three years away. The announcement of the process would occur in 2019. Details to follow. People who sell airplanes understand buyers are both fickle and fragile and the slightest whiff of uncertainty can tank a deal.

The Stratus is still out there, but now in its third generation and with open architecture so it works with other apps. ForeFlight’s new product is the $499 Sentry, a diminutive box that combines a dual-band ADS-B receiver with a carbon monoxide detector, plus AHRS. uAvionix – they’re the guys everyone is waiting on to deliver the wingtip- and tail-mounted ADS-B Out units-designed and builds the Sentry for ForeFlight. Once again, it works only with that app. In concert with its push to establish a market for mid priced panel-mount avionics, Dynon showed up at AirVenture 2018 with the DRX, which clearly aims to anchor the bargain end of the price spectrum. No frills on this one; just the dual-band receiver and a little case for $349 discounted, $395 list.

However, the Partevania purchase got Vulcanair the rights to the P68, a Luigi Pascale-designed twin that found a market in the training and light transport segments. It’s powered by a pair of Lycoming IO-360s. Vulcanair lists six variants of the P68, including the P68R retractable and two Observer versions, one of which features a glazed nose for observation and patrol work. A stretch version of the aircraft, called the A-Viator, is powered by Rolls-Royce 250B turboprops and carries nine passengers and two crew. There are 49 P68s in service in the U.S., including three turboprop versions, according to the FAA registry.

Although its really an incremental upgrade to the long-body M20 series, the Acclaim Ultra was a major certification project for Mooney at a time when were not seeing many of those-from anyone. The results inarguably make the Acclaim Ultra the fastest four-place certified single-engine piston airplane and not just by a little. The Acclaim goes head to head with both its normally aspirated sibling, the Ovation Ultra (see February 2018 Aviation Consumer) and both Cirrus models, the SR22 and SR22T which, together, constitute the current market leaders. That puts the Acclaim into a niche within a niche-a slice of buyers who want speed, but care less about cabin size or payload. Pricewise, at $789,000 base, the Acclaim invoices below the typical Cirrus models.

AeroVonics has in mind inexpensive replacements for vacuum instruments with its AV-20 and AV-30 self-contained multifunction instruments. The $800 AV-20 fits into a 2-inch instrument hole-the size of a typical clock-and provides 11 discrete functions, including attitude, AoA, bus voltage, flight timer, TAS display, G-meter and a clock. There are actually two versions of the instrument. The AV-20 is a minimal variant that doesnt have the gyro sensing. It will sell for about $499. The AV-20S packs all the features. We saw the instrument demonstrated at AirVenture and although it appeared to have some sort of extraordinarily sharp display, AeroVonics Jeff Bethel says no, its just a garden-variety TFT. But the AV-20s software tweaks the graphic processing at the sub-pixel level, giving the instrument dense colors and smooth refreshes.

The long, torturous road to replace 100LL with an unleaded alternative just got longer and more torturous as the FAA temporarily halted testing on the two leading candidate fuels in May. The agency said its testing revealed differences significant enough with 100LL to obviate further testing.
