Wichita, KS -- Belite Aircraft, which recently introduced the revolutionary solid state line of extremely lightweight avionics, has added additional instruments: a dual Cylinder Head Temperature Gauge (CHT) and a dual Exhaust Gas Temperature (EGT) Gauge. In addition, the full panel has changed to add a slot for the Patch Flyer Volt MiniMeter (VMM). The Patch Flyer instruments are perfect for Experimental and Part 103 aircraft.

“We’ve received many requests for additional instrument types, and the dual CHT / dual EGT are among those that customers want,” said James Wiebe, CEO of Belite Aircraft. “Also, by changing our panel layout slightly, we’re able to accommodate more functionality. We think pilots will like the improved layout.”

Individual Patch Flyer instruments weigh only 1/2 ounce (15 grams), and the panel-mounted full line of instruments, including metal panel, mounting hardware and connections, weighs substantially less than one pound. They’re designed to easily fit into instrument panels of homebuilt and ultralight aircraft. Installation is straight-forward and many of the instruments are also available in small enclosures which can be carried in the pilot’s flight bag and used in whatever plane they are flying.

The Patch Flyer Cylinder Head / Exhaust Gas Temperature Gauge (CHT/EGT) is a high precision device that provide a quick visual indication of engine temperatures using a 24 LED column for each parameter. Unlike other Patch Flyer avionics, this product is a little bigger, at 3.5 x 1.75 inches, and comes with a mounting bezel. The LEDs use color to alert the pilot when things start getting hot; the display LEDs switch from bright yellow to ultra bright amber at high temperatures. It’s also well calibrated and built with engineering precision to deliver accurate readings. It doesn’t have any switches, so it’s easy to use.

Additional instruments available from Belite Electronics are:

The Patch Flyer Vertical Speed Indicator (VSI) provides vertical speed information using a dimmable LED display that can be adjusted for viewing in bright daylight or reduced lighting conditions. Featherlight, the base unit, with bezel and electrical connector, weighs only 15 grams—1/2 ounce—and is extremely easy to use; it has no buttons to turn or push. It is calibrated from 0 to +/- 500 feet per minute (fpm) in 50 fpm initial increments and 100 fpm steps thereafter.

The Patch Flyer ASI uses a solid state pressure sensor device which converts pitot air pressure into a visual speed indication. It is specifically calibrated for the slow flight and designed to provide much more precise measurement of “low and slow” airspeeds than nonprecision steam gauges.

The Patch Flyer Turn Rate Indicator (TRI) is a solid state gyro-based turn rate indicator calibrated at 3 degrees per second for a two minute turn and configured so that the LEDs show when that rate is not being met. With 7 LEDs on each side representing neutral, 3 left turn rates and 3 right turn rates, and displaying colors from bright yellow to ultra bright amber, each position depicts a 1.5 per second turn rate and blanks if a turn rate of 4.5 degrees per second is exceeded. This practical device is not only useful for homebuilts and ultralights, the portable version can be utilized as a training aid in certified aircraft, as well, since it alerts student pilots to turn rate errors quickly and obviously when compared to a traditional mechanical gyro instrument. It’s also substantially less expensive.

The Patch Flyer Above Ground Level Altimeter (AGL) is a practical and useful device that offers an extremely bright LED display that is calibrated in 100-foot increments from 0 to 1200 feet and measured from the field elevation of the airport (rather than mean sea level) with the simple push of a button. The feather light unit weighs only ½ ounce, including bezel and electrical connector.

The Patch Flyer Inclinometer (INC) uses an LED display to simulate and improve upon the classic ball and bubble slip and skid device. An ideal flight instruction aid, it displays a slip or skid brightly and with even more immediacy than a conventional instrument. It’s also simple to use with no buttons to push or set.

The Patch Flyer Positive G Head (GHD) shows how strong the bumps are! A great training aid as well, it provides an exceptional visualization, with 13 LEDs depicting forces up to 4Gs. The precision solid state accelerometer inside exceeds the capabilities of older mechanical units. In addition to panel mount versions, a portable version is also available. This device slowly resets after big bumps and can be reset manually anytime by hitting a button.

The Patch Flyer Battery Condition Voltmeter (BCV) is calibrated in quarter volt steps from 11.0 to 14.5 volts with the highest and lowest levels using ultra bright amber LEDs to provide warning of low and high voltage levels. It provides instant information at a glance. The Patch Flyer Volt MiniMeter (VMM) is even lighter at 4/10 of an ounce and draws only 3/10 of a milli-amp. It’s a general purpose voltmeter that can be permanently attached to an aircraft’s electrical system, without fear of draining the battery, to provide an indication of how much voltage is in the system.

The Patch Flyer Fuel Gauge (FGA) is a fuel gauge that actually works. It uses LEDs to provide a range of 0% to 100% in calibrated steps. It is designed to be used with a capacitive fuel sender, and may be calibrated for any tank capacity or any tank dimension. All LEDs are bright yellow, except for 20%, 10%, 5% and 0%, which are ultra bright amber. At a feather weight of ½ ounce, this fuel gauge won’t break the weight budget either.
