The TDO 915iS puts the turbocharged 141 HP Rotax 915 iS into the tailwheel Bristell. Cruise up to 155 KTAS, strong climb at altitude and heavy-duty wing spars standard.
All-metal low-wing tailwheel configuration with a wide 130 cm (51 in) cockpit. Heavy-duty spars standard for confidence in turbulence and on rougher strips.
Configure up to a full Garmin G3X Touch glass panel with autopilot, well matched to the faster cross-country legs the turbo makes possible.
Two Garmin G3X Touch glass displays showing flight instruments, moving map and full engine monitoring. Touch control with physical knobs as backup, so the pilot is not fighting a touchscreen in turbulence.
Analog flight instruments (airspeed, altitude, vertical speed, compass) plus analog engine gauges, the standard panel on the UL/LSA base aircraft. A simple, familiar layout popular for ab-initio training and pilots who prefer a serviceable panel. Glass can replace or supplement it.
Garmin GMC 507 autopilot with a dedicated Blue LEVEL button that returns the aircraft to wings-level flight at a single push. It handles the routine legs to cut pilot workload, and the pilot stays in command for the parts that matter.
Garmin GNC 215A NAV/COM radio for communication and VOR navigation, a certified backup to GPS navigation.
Touchscreen GPS, NAV and COM navigator with LPV approach capability for instrument approaches down to near-precision minimums.
B23 is certified for Night VFR with the glass cockpit, autopilot and lighting to support it. On UL/LSA models night flying is a build-up option, not a certification.
Garmin Flight Stream 510 linking the panel to a tablet for wireless flight- plan transfer, weather and traffic with ForeFlight or Garmin Pilot.
Turbocharged and intercooled Rotax 915 iS with FADEC engine management, delivering 141 HP (103.7 kW) and holding full take-off power up to 15,000 ft (4,572 m). Strong climb and confident high-altitude cruise.
Configured to order · matched to the Rotax 915 iS
Choose between an economical fixed-pitch propeller and a constant-speed unit that holds its optimal blade angle across climb and cruise. Every Bristell is built to order, so the propeller is matched to your engine and mission.
High cruise and strong climb on a single Rotax burning MOGAS or AVGAS, in a light UL airframe. An optional 164 L (43.3 US gal) tank extends your range.
All Rotax engines run on both MOGAS RON 95 and AVGAS 100LL. MOGAS saves up to 30% on fuel cost — and is available almost anywhere.
Heavy-duty wing spars for turbulence and rougher strips, standard on every tailwheel Bristell — with a BRS parachute available.
Ballistic parachute that lowers the entire aircraft under a canopy in an emergency. Works within a defined minimum altitude and speed envelope.
Benign, forgiving handling with gentle stall characteristics and no sudden wing drop, which gives the pilot time to react. Well suited to training and lower-time pilots.
4-point AmSafe restraint system for both occupants on premium leather seats — better restraint and load distribution in a hard landing or impact.
AT1 active traffic unit that shows surrounding traffic directly on the glass cockpit, independent of ADS-B coverage.
Garmin transponder with ADS-B In and Out. Displays nearby traffic and makes the aircraft visible to ATC and other aircraft. Meets the FAA 2020 ADS-B Out mandate.
406 MHz emergency locator transmitter that signals the aircraft's position to search-and-rescue satellites after a hard landing or crash.
Whelen wing strobes and navigation lights that keep the aircraft visible to other traffic, day and night.
Dedicated backup battery (IBBS) that keeps the glass cockpit powered during an alternator or electrical failure.
Independent standby display that keeps attitude, airspeed and altitude available if the main glass display fails. Garmin GI 275 on B23, G5 on UL/LSA.
All-metal aircraft structure that deforms predictably under load and shows damage on the surface, unlike composite where damage can stay hidden. Fatigue behavior is predictable and well understood.
Aithre cockpit carbon monoxide monitor that warns of CO before it affects the pilot.
