DESIGN & GALLERY

The B23 airframe, built for performance.

All-metal, low-wing construction engineered to FAA Part 23 standards, with bubble-canopy visibility and the class-leading 51 in (130 cm) cockpit. An LSA under the new MOSAIC rules, with certified-grade bones.

Avionics & Technology

Your panel, your way.

Every B23M-915iS leaves the factory with the panel its owner specified, built for the longer, higher trips this airframe flies. The Garmin AXIS glass cockpit is available — NAV/COMM radio and audio panel built into the display, so one screen replaces the radio stack — alongside the GMC 507 autopilot, ADS-B In and Out and a GI 275 backup display.

Garmin AXIS glass cockpit

Optional

Garmin's integrated flight display, with the NAV/COMM radio and audio panel built into the screen — one display replaces the whole radio stack. Carries SafeTaxi, synthetic vision and a dedicated emergency button.

Autopilot with LEVEL button (Garmin GMC 507)

Optional

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.

Powerplant

Rotax 915 iS

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.

Power: 141 HP / 103.7 kW
Fuel: MOGAS / AVGAS
TBO: 1,200 hours

Propeller of Your Choice

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.

Operating Economics

Turbo performance, LSA simplicity.

Turbo climb and altitude capability on a single Rotax burning MOGAS or AVGAS, inside the MOSAIC LSA framework. Lower running cost than legacy high-performance singles.

Refuelling a Bristell with MOGAS at a fuel station

MOGAS + AVGAS Compatible

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.

Safety & Certification

Safety that climbs with you.

Benign handling and a 4-point AmSafe harness on an all-metal airframe engineered to FAA Part 23 standards, with a BRS parachute available.

BRS whole-aircraft parachute

Optional

Ballistic parachute that lowers the entire aircraft under a canopy in an emergency. Works within a defined minimum altitude and speed envelope.

Predictable behavior

Standard

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 safety harness

Standard

4-point AmSafe restraint system for both occupants on premium leather seats — better restraint and load distribution in a hard landing or impact.
