Common use of Performance Definitions Clause in Contracts

Performance Definitions. 5.2.1. Performance and noise certification rules will be those required to obtain FAR certification under the FAA Airworthiness Code as defined in the Type Specification. 5.2.2. All performance data is based on the International Standard Atmosphere and specified variations. Unless otherwise stated all altitudes are pressure altitudes. 5.2.3. Unless otherwise stated, take-off and landing performance is based upon a hard, smooth, dry and level runway surface with zero wind. 5.2.4. Take-off and landing performance is based on the brakes and tires as specified in the aircraft configuration defined in the Preamble. 5.2.5. Devices such as flaps, landing gear, speed brakes, wheel brakes, anti-skid and engines will be employed in the manner which provides the best performance standard consistent with approved operations. 5.2.6. All guaranteed performance in this Part A is based upon no air bleed from the engines for airframe or engine anti-icing. 5.2.7. For take-off and take-off climb performance, landing and landing climb performance, no air will be bled from the engine for air conditioning. 5.2.8. For en route performance, engine bleeds consistent with normal operation of the air conditioning system, including recirculation, are assumed. 5.2.9. Normal electrical services will be in use consistent with the typical load schedule given in the A319 Standard Specification. 5.2.10. All guaranteed performance in this Part A assumes the use of approved fuel with a Lower Heating Value (the "LHV") of 18,590 BTU/lb. and with a specific gravity of 6.7 pounds / gallon as such.
