“Upper Left” Corner Expansion: assists in forward occupant(s) with full fuel loading condition

V-Speeds: Changes due to movement

of the pitot tube and wing root fairing induced changes to the aircraft pressure field.

The calibrated airspeeds are the same. The indicated values have changed to account for the differences.

HandlingGround Handling: is not noticeably different from the G2 other than for the initial impression that the rudder force is lighter and the fact that during cross wind takeoffs it is easier to get the aircraft to lift the downwind wheel off the ground prior to reaching rotation speed, in a G2 this is not normally possible.Cruise Flight: No significant change in typical characteristics Lateral Stability - slightly more positive than the G2 resulting in the

elimination of the requirement for an aileron rudder interconnect system. Dutch roll remains heavily damped, with less than 2 overshoots following a perturbation.

Turning Flight - with the rudder-aileron interconnect removed, turning flight results in a more natural and balanced feel.

Low-speed: Continues to deliver exceptional low-speed and departure resistance characteristics.

Flight and PerformanceFlight and Performance

“The SR22-G3 is a continued refinement of an already nice flying light aircraft. The handling qualities are a harmonious mixture that results from the desire to have an agile sport aircraft feel while maintaining suitability for the personal air transport mission ”.

Mike Stevens, Director, Engineering Flight Test

Flight and PerformanceFlight and Performance

PerformanceRange and fuel reserve both increased with an eleven gallon addition to the useable fuel resulting in 30-60 minutes more endurance for the typical user. 1170 NM range obtainable at 55% power economy cruise.

Take off and landing distance increased slightly (less than 50ft) due to the increased stall speed resulting from the CG envelope expansion.

Flight and PerformanceFlight and PerformanceNew Wing Root Fairing

Aerodynamics Reduces air separation at the trailing edge

of the wing near the fuselage. Reduction of this separation gives a small increase in cruise speed and rate of climb.

Fit and Finish A single large access panel replaces

multiple smaller access panels to provide better access and reduced drag due to the better fit of the single panel.

Note: Reduces step area

Environmental Control SystemEnvironmental Control System

Fresh air enters upper right hand cowl and is ducted to a heat exchanger surrounding exhaust muffler. Heated air is then routed to the mixing chamber to be mixed with fresh air, received from the new NACA vent on the lower right hand cowling, if selected from within the cabin. If heated air is not desired it is vented overboard prior to the mixing chamber. The air is then routed by the blower fan or ram air to the cabin or sent to the evaporator assembly if AC equipped.

G3 QuizG3 Quiz

Explain how air for the environmental system enters the cabin.

Fresh air enters the lower right hand NACA vent and is routed to the air mixing chamber where it is mixed with heated air that entered the right cowl air intake and passed over a heater shroud. The air is mixed and sent to that cabin via the blower.
