When lowering both main landing gear on one side, which gear is lowered first?

Lowering the forward gear first on one side when lowering both main landing gear is critical for maintaining aircraft stability and control. This sequencing is designed to ensure that the center of gravity is adequately managed during the gear deployment process.

When the forward gear is lowered first, it establishes ground contact earlier, providing a stable reference point for the aircraft. This helps reduce the potential for any asymmetric forces that could arise if the aft gear were lowered first. By adhering to this procedure, pilots can ensure a more predictable landing gear extension, minimizing the risk of complications during landing or taxi operations, particularly on uneven surfaces.

In contrast, lowering both gears simultaneously or without a specified order could lead to instability during the landing gear deployment, as the aircraft may experience unanticipated pitching or rolling motions as weight shifts unexpectedly. Therefore, the practice of lowering the forward gear first is a key aspect of ensuring safe landing gear operations.
