Implemented enhancements:
CLB1/2 - Climb thrust derates that are gradually removed as the aircraft climbs.
- CLB1/2 typically uses a 8.6/17.2% derate of CLB thrust to 10,000ft, then increases thrust linearly with altitude to CLB thrust at 30,000ft. Reference : Rolls-Royce Derated Climb Performance In Large Civinl Aircraft - Article 6 - Figure 4. Climb derate tapers
