What is the type-H support system similar to?

The type-H support system is similar to the BAK-14 system in that both are designed to provide effective support for aircraft operations, particularly in terms of moving and supporting aircraft on the flight line. The type-H support system is characterized by its structure that can handle multiple configurations and ensure stability during various loading conditions, which is a common feature found in the BAK-14.

While the other options may represent various support systems or components used in aircraft operations, they do not align closely in functionality and design with the type-H support system as the BAK-14 does. The BAK-12 and BAK-14 typically have different specifications and operational capabilities, while the type-S support system has its unique characteristics that distinguish it from the type-H. The MA-1A is also a different type of support system, focused more on specific aircraft models, which further differentiates it from the type-H support system.
