Common use of Climb Clause in Contracts

Climb. The Aircraft climbs from *** feet above the departure airport altitude to *** feet altitude at *** KCAS. The Aircraft then accelerates at a rate of climb of *** feet per minute to the recommended climb speed for minimum block fuel. The climb continues at the recommended climb speed for minimum block fuel until *** Mach number is reached. The climb continues at *** Mach number to the initial cruise altitude. The temperature is standard day during climb. Maximum climb thrust is used during climb. Cruise: The Aircraft cruises at *** Mach number. The initial cruise altitude is *** feet. A step climb or multiple step climbs of *** feet altitude may be used when beneficial to minimize fuel burn. The temperature is standard day during cruise. BOEING / UNITED AIR LINES, INC.
