Reduced Engine Maintenance Costs
Better climb performance also allows lower thrust settings, thus extending engine life and reducing maintenance costs. Takeoff thrust is typically reduced by 3%. Cruise thrust is typically reduced by 4%.
Reducing Thrust will:
- Slow EGT deterioration, which prolongs on-wing life between engine shop visits
- Reduce fuel flow deterioration, which results in lower fuel burn
- Lower maintenance costs by increasing time between shop visits (longer on-wing life)
