FLIGHT MANUAL

7.4

Undercarriage

The main wheel of the Arcus M is retractable with shock absorber struts and
features a hydraulic disc brake. The nose wheel (if installed) and tail wheel (or
skid) are fixed.

The extension/retraction process of the main wheel is described on page 7.2.7
(cockpit description). The operation of the main wheel brake is given on page
7.2.4.

For a technical description of the retractable undercarriage including its wheel
brake system see also page 1.2.3 of the Arcus M Maintenance Manual.
