Cirrus SR22TN (Tornado Alley Turbonormalized)

Buyer context and ownership considerations

Treat an SR22TN comparison as a review of both the base aircraft and its installed modification.

What to verify on the aircraft

• Confirm the base SR22 model and serial, engine identity, installed STC documents and applicable flight-manual supplement.
• Use the approved supplement for the installed configuration; vendor performance does not replace it.
• Review modification records, maintenance instructions, CAPS calendar items and current support before comparing a modified SR22 with an SR22T.

Use the source-tagged specifications below as research context. Retain the stated model, serial, configuration, units and source limitations. NOT VERIFIED means further evidence is needed.

Takeoff Over50 Ft

Conditional base-SR22 AFM tables at 3,400 lb, sea-level ISA, zero wind, 50% flaps and takeoff power: 13772-001 Reissue A Figure 5-9 gives 1,574 ft over 50 ft (1,020-ft ground roll), 73 KIAS liftoff / 78 KIAS obstacle, dry paved surface. 13772-002 Reissue A (2013) gives 1,594 ft over 50 ft (1,028-ft roll), same speeds, dry paved level surface; add its prescribed 150 ft over-50 distance if air conditioning is ON. Select the controlling aircraft-specific AFM and all applicable corrections. [POH/AFM; conditional TN base-handbook referral]Report 215-6 Rev 1 (April 3, 2007) refers non-tabulated performance to the aircraft’s controlling base SR22 AFM. Figures below are conditional on matching the installed handbook, serial, equipment and supplements; they do not establish universal applicability to every SR22TN or later 3,600-lb aircraft. Perspective 13772-002 cover specifies serials 2979, 2992, 3002, 3026 and subsequent with Perspective; TN supplement applicability must independently match.

Max Range Nm

Later-serial SR22TN: 992 NM at 22,000, 24,000 or 25,000 ft, 65% power with lean-of-peak climb and cruise. At 22,000 ft: 186 KTAS, 14.0 GPH, 4.8 hr. [AFMS manufacturer data; Section 5 not FAA approved]Tornado Alley Report 215-6 Rev 1 (2007-04-03), S/N 2334, 2420, 2438 and subsequent with the applicable installation: 3,400-lb takeoff, 92 US gal usable, zero wind; subtract 1.5 gal taxi, climb fuel and 10.5 gal / 45-min IFR reserve at 60% power. Section 5 data expressly not FAA approved; no applicability to other SR22/SR22T configurations.

Endurance Hr

Published SR22TN cruise-endurance column at 2,000 ft pressure altitude, 65% power, lean-of-peak climb and cruise, 153 KTAS / 14.0 GPH: 4.9 hr for serials through 2437 except 2334/2420 (81 gal usable); 5.7 hr for serials 2334, 2420, 2438 and subsequent (92 gal usable). These are cruise time after the table deducts taxi, climb fuel and reserve, not total elapsed mission time or a family-wide maximum. [AFMS manufacturer data; Section 5 not FAA approved]Tornado Alley Report 215-6 Rev 1, April 3, 2007; 3,400-lb takeoff, zero wind, 1.5 gal taxi, climb fuel and 10.5 gal for 45-min IFR reserve at 60% power. Exact serial/fuel and lean-of-peak climb technique must match; later changes not established.
