Sport Pilot

How We Qualify

The sport pilot certificate allows persons to operate aircraft that meet the following criteria. We've listed how all Sonex Aircraft models (with the exception of the SubSonex Personal Jet) meet each of these criteria below:

1. Gross Weight: 1320 pounds or less
All Sonex Aircraft models have a max gross weight of less than 1320 lbs.

Important Note: Any builder considering use of an alternative engine installation or modifications to the aircraft should take notice of the important information contained in our Gross Weight Advisory Letter (LSA Compliance and Safety).

2. Vs: 45 knots or less (51 mph)
All Sonex and Waiex Models have a clean stall speed of 46 mph (40 mph flap extended stall speed). Xenos Models have a clean stall speed of 44 mph. The Onex has a clean stall speed of 50 mph.

3. Maximum speed in level flight with maximum continuous power (Vh) of not more than 120 kts (138 mph) CAS under standard atmospheric conditions at sea level.
Sonex, Waiex, Xenos, and Onex all meet this requirement with their standard propellers for all factory-approved engine installations.

The most common question on these speeds involves the use of the 3300 Jabiru. According to the Jabiru Factory, the maximum continuous power rating of the 3300L Jabiru is 2850 rpm. At this rpm and under the specified conditions, the Sonex and Waiex cruise at 135 mph and the Xenos cruises at 100 mph.

4. Unpowered or single engine-powered
Met by all Sonex Models

5. Unpressurized
Met by all Sonex Models

6. Two occupants or less
Met by all Sonex Models

7. Fixed Landing Gear
Met by all Sonex Models (except SubSonex)

In conclusion, the Sonex, Waiex, Xenos, and Onex all Meet the Sport Pilot Criteria. The Sonex was designed and built in 1997 to meet the "Ultralight" and "Light Aircraft" Standards from other countries including Italy, Great Britain, Canada and Australia (just to name a few). These International Standards fit within Sport Pilot/LSA rules.

The Sonex family of aircraft are the ideal Sport Pilot Aircraft with their simple construction, affordable price, minimal instrumentation, and large performance envelope. The Sport Pilot represents a fantastic opportunity for the Recreational Pilot to keep flying affordable and fun!
