What is the primary purpose of MLA in aircraft operation?
What is the primary purpose of MLA in aircraft operation?
- To increase engine power for better performance
- To redistribute lift and relieve structural loads on the outer wing surfaces (correct)
- To improve fuel efficiency during flight
- To enhance passenger comfort during turbulence
Under what conditions does the MLA become active?
Under what conditions does the MLA become active?
- When the ailerons are symmetrically deflected upwards
- When the aircraft speed is below 250 kt and flaps are deployed
- When the aircraft is in a steep climb

Study Notes
Meaningful Load Alleviation (MLA) System
- MLA redistributes lift over the wing, reducing bending moment on outer wing surfaces while maintaining the desired load factor.
- MLA uses spoilers 4, 5, and 6, and ailerons.
- MLA activates when the sidestick is pulled more than 8° and load factor exceeds 2 g.
- Ailerons deflect symmetrically upward, up to a maximum of 11° (additional roll demand).
- Spoilers 4, 5, and 6 deflect symmetrically, adding up to a maximum of 9° (additional roll demand). Deflection increases proportionally with load factor above 2 g.
- Elevator control simultaneously compensates for pitching moments from spoilers and ailerons.
- Load alleviation is available if: Aircraft speed is above 250 kt. FLAPS lever is in the "0" position. Normal or alternate law flight mode selected.
- MLA has priority over the speedbrakes.
