KINDS OF OPERATION EQUIPMENT LIST The Liberty XL-2 is equipped for day/night VFR and IFR operations. Flight into known icing or forecast icing is prohibited. Table 2-5, Table 2-6, and Table 2-7 identifies the systems and equipment upon which type certification for each kind of operation was predicated. This list does not include specific flight and radio/navigation equipment required for any particular country s operating regulations. The pilot-in-command is responsible for determining the airworthiness of the airplane and assuring compliance with current operating regulations for each flight. The zeros used in the list below indicate that the system and/or equipment were not required for FAR Part 23 type certification for that kind of operation. The ATA numbers refer to equipment classification of Air Transport Association Specifications. P/N 135A-970-300 FAA Approval: March 30, 2010 Section 2 Initial Release Page 15 of 18
