High-quality avionics

Glance Avionics offers a modern alternative to the traditional electromechanical cockpit instruments that most ultralights, experimental and homebuilt aircraft currently use. The EFIS is an advanced, high-quality avionics unit that will transform the look of the aircraft’s instrument panel as well as transform the flying experience for the pilot.

EFIS for ultralight and experimental aircraft

The avionics could be installed on a variety of aircraft types including ultralights, experimental aircraft, homebuilt aircraft, both flex-wing and 3-axis microlights, as well as helicopters and gyrocopters. The EFIS is exceptionally good value for money, at roughly 15% cheaper than the next competitor.

The 5.7” display provides a clear and concise interface between the pilot and the EFIS, offering easy-to-read text with good contrast and adjustable brightness levels; this gives any cockpit a decluttered and modern looking appearance. The pilot interacts with the EFIS using the three large buttons to the right of the display, these buttons allow the pilot to use the system easily, even with heavy cockpit vibration or during severe turbulence.

Avionics installations

The unit is incredibly easy to install and can be retrofitted to most aircraft in any garage. However, it is highly recommended that avionics installation is done at an authorized service center, fortunately, there are numerous authorized service centers located in Europe and both North and South America, therefore getting your EFIS installed should not be a problem.

avionics architecture

The unit is an incredibly lightweight piece of hardware, at only 800 grams, however, despite this, it is extremely rugged and will continue to operate in very harsh weather conditions with a specified temperature range of -30˚C to +80 ˚C. Also, the EFIS is compatible with a wide range of input voltages, ranging from 9 – 35 V.

Flight display

The flight information page gives the pilot access to an impressive plethora of information, the
accuracy of which could not be reciprocated by traditional electromechanical instruments. The flight display shows everything that the modern day pilot would expect to see on a glass cockpit.

The attitude indicator is placed squarely in the center of the flight display with the AOA indicator, cross track
error and the corresponding cross track error pointer layered over the top. To the left of the attitude indicator the display shows the ground speed and the airspeed, and to the right, the pilot will find information relating to the barometric altitude and the aircraft’s vertical speed. At the top of the page the display shows zulu time and local time, along with a time zone indicator, target waypoint information, bearing information, ETA and distance to waypoint.

The EFIS is capable of interfacing with the aircraft’s engine and the pilot will find engine monitoring indicators located in the lower part of the flight information page, this provides the obvious benefit of allowing the pilot to view the primary flight instruments as well as monitor the engine from the same page.

Engine Monitoring

The avionics is equipped with an internal engine monitoring system that is set up for use with Rotax 912/582 engines. This will allow the pilot monitor key parameters such as fuel quantity, the oil temperature and pressure, cylinder head temperature, the engine RPM, and the manifold air pressure.

For aircraft that do not use Rotax engines, an external EMS module can be used to send data to the EFIS. The avionics is able to monitoring two engines at a time and therefore the EFIS is capable of detecting two external EMS. When external EMS units are installed on the aircraft the pilot must navigate to the dedicated engine monitoring page. The engine monitoring page will show the pilot information relating to the engine RPM, rotor RPM, total HOBBS, engine coolant temperature, oil pressure, oil temperature, fuel pressure, fuel flow rate, manifold intake temperature, manifold air pressure, cylinder head temperatures for up to nine cylinders, exhaust gas temperature for up to nine cylinders, battery current, battery voltage and fuel tank levels for up to two fuel tanks.


In addition to the flight information page and the engine monitoring page, the avionics also includes a navigation page. This gives information about the aircraft’s current position, the current course, the flight plan, target waypoint, the course to the target waypoint and the flying course as well as nearby airspace information such as airspace boundaries, altitudes, and distances. The EFIS is equipped with internal GPS and GLONASS receivers, and also features magnetic declination and true-magnetic course calculation.

avionics with navigation

The navigation database is easily loaded into the EFIS via a MicroSD card, discretely located in the top right-hand corner of the system. The EFIS also has a worldwide navigation database that can be updated every 28 days, for an annual subscription, or annually, for free. One of the newest features to be added to the EFIS is the addition of a moving map to the navigation page; a zooming range is also a feature of this page.

The navigation page will also aid the pilot in their flight planning. The system can save and load
previous flight plans from the MicroSD card, whilst also providing the facility for waypoint distance
and course calculation, including estimated ETA calculations.

For aircraft where multiple EFIS need to be installed, the system also incorporates networking features, allowing up to three displays to be installed in a single cabin. The multiple displays are then able to synchronize flight plan and user waypoint data, as well as share basic baro, date and time, NMEA co-ordinates and navigation transmission data.

Other features that can be found on the EFIS include preflight checklists, flight timers and flight logbooks. The preflight checklists are simple to create and are loaded onto the EFIS using a .txt file on the MicroSD card.

Customers review

Past customers are also pleased with the unit and have left positive comments and feedback after getting their EFIS installed, one aerobatics pilot reported that the

engine monitoring instrument is very reliable and informative

. Another customer was impressed by the unit’s impressive reliability,
stating that

It was about -20˚C here, but everything was perfect. I fly almost every weekend and I definitely recommend Glance EFIS for everyon

. Finally, a customer who took the EFIS on a cross-country flight had the following to say:

I am 100% satisfied with the navigation system features (OBS-approach works perfect).

The EFIS is one of a range of products currently manufactured by Glance EFIS. As previously mentioned, the EFIS can operate with two external EMS modules, these are also manufactured by Glance Avionics, as well as an AHRS system, a flight recorder system and a variety of sensors for measuring different engine parameters. However, perhaps most exciting is the Heads Up Display a system which is currently in development and can be viewed at the Glance Avionics website.


Since the company was founded the EFIS has developed a fantastic reputation for its durability, robust design and general reliability. This reliability is reflected in the EFIS’s decision to offer a three-year warranty and a 30-day money back guarantee with every unit sold. The EFIS has already been fitted to a huge variety of aircraft, from the Antonov An-2, to the acrobatically capable Yak 52 and to the timeless Cessna 150. So far, whichever aircraft the EFIS is been fitted to, the system has not failed to take the cockpit into the next generation and give it a sublime and modern appearance.

The EFIS is dedicated to creating advanced avionics systems for light aviation aircraft and is
striving to give unmatched value for money with its range of products. Recently the company has been able to announce a partnership with engine overhaul and repair company M-14P Inc. This partnership will give confidence to any customer who might be considering fitting a Glance EFIS system to any aircraft which uses the classic 9-cylinder rotary M14P engine, historically, this includes many Sukhoi and Yakovlev designs, making the EFIS an ideal choice for aerobatic pilots.

Glance EFIS’ well-deserved reputation for reliability has also led to several Reno Air Race teams, who compete in the Formula One category, making the decision to use the EFIS on their aircraft. It is safe to say that if you fly an ultralight, or an experimental, or a homebuilt aircraft, the EFIS has something in their product range that will bring your cockpit to the next level.
