Smart Glide Is Coming to the Cessna 172 and 182 — What G1000 NXi Release 7 Means for Piston Pilots
Garmin and Cessna announced System Release 7 for the G1000 NXi, bringing Smart Glide automated engine-out landing capability to new 172 and 182 aircraft starting late 2026.
Automated Engine-Out Protection Arrives for Piston Pilots
Garmin and Cessna just announced System Release 7 for the G1000 NXi avionics suite, and it's bringing a major capability to piston aircraft: Smart Glide, an automated guidance system for engine-out landing scenarios. New Cessna 172 and 182 aircraft will begin receiving the upgrade in late 2026 and into early 2027.
What Smart Glide Does
Smart Glide is an automated landing guidance system designed to walk you through the most critical phase of an engine-out emergency. When activated:
1. Best-glide guidance: The system calculates and displays your aircraft's optimal glide speed and hands you a highway in the sky to follow
2. Nearest-airport routing: It identifies suitable landing airports within your glide envelope and sequences them by proximity
3. Stabilized approach guidance: As you descend toward the chosen airport, Smart Glide provides cross-check cues to maintain a stabilized approach
This isn't autopilot for landing—you fly the airplane. But Smart Glide removes the mental load of speed management, airport selection, and descent planning at the moment when you most need that mental bandwidth focused on flying the aircraft smoothly.
The Bigger Picture: Garmin's Autonomi Lineage
Smart Glide builds on Garmin's existing Emergency Autoland (Autonomi) system, which has been in certified turboprops and jets for several years. That system can fully automate an engine-out landing in an emergency. Smart Glide is the piston-aircraft equivalent—not fully autonomous, but highly automated guidance.
The difference reflects the aircraft classes. Turboprops and jets have the system architecture, redundancy, and performance margins for full autonomy. Piston singles need a different approach: augmented pilot control with machine intelligence on top.
Timeline and Availability
New production Cessna 172 NXi and 182 T aircraft will ship with Release 7 starting in late 2026 through early 2027. That's the firm timeline.
The big question for current owners: retrofit availability. Garmin hasn't announced retrofit plans yet. That's the next watch point.
What This Means for GA Pilots
If you fly a piston single, especially in terrain where engine-out options are limited, this matters. Engine failure is rare in modern aircraft, but when it happens, you want every advantage. Smart Glide stacks the deck in your favor by removing decision-making burden and providing proven guidance. For new aircraft buyers, it's a compelling safety feature. For current owners, stay tuned for retrofit announcements.
