What is the primary advantage of pneumatic (air turbine) starters over electric starters for turbine engines?

There is no significant wear to the commutator.
It does not disengage until the engine reaches idle.
It has a high power-to-weight ratio.
It uses less electrical power during startup.

The correct answer is: It has a high power-to-weight ratio.

Pneumatic (air turbine) starters have a high power-to-weight ratio, meaning they can provide a high power output with a relatively light weight. This is advantageous for turbine engines, which require a lot of power to start up and get moving. Electric starters, on the other hand, may have a lower power-to-weight ratio, making them less efficient for starting turbine engines. Options A, B, and D are incorrect because they do not fully explain the primary advantage of pneumatic starters over electric starters for turbine engines.
