Tiedown; Leveling - Cirrus SR22 Pilot Operating Handbook

Section 8
Handling, Servicing, Maintenance

Tiedown

The airplane should be moored for immovability, security and
protection. FAA Advisory Circular AC 20-35C, Tiedown Sense,
contains additional information regarding preparation for severe
weather, tiedown, and related information. The following procedures
should be used for the proper mooring of the airplane:
1. Head the airplane into the wind if possible.
2. Retract the flaps.
3. Chock the wheels.
4. Secure tie-down ropes to the wing tie-down rings and to the tail
ring at approximately 45-degree angles to the ground. When using
rope or non-synthetic material, leave sufficient slack to avoid
damage to the airplane should the ropes contract.
Anchor points for wing tiedowns should not be more than 18
feet apart to prevent eyebolt damage in heavy winds.
Use bowline knots, square knots, or locked slipknots. Do not
use plain slipknots.

Leveling

The airplane is leveled longitudinally by means of a spirit level placed
on the pilot door sill and laterally by means of a spirit level placed
across the door sills. Alternately, sight the forward and aft tool holes
along waterline 95.9 to level airplane. Refer to Section 6, Airplane
Weighing Procedures and Section 6, Figure 6-2, for illustration.
