Techniques for remotely adjusting a portion of an airplane engine

A remote adjuster to remotely adjust a portion of an airplane engine, the remote adjuster comprising:

• a first operative end which is configured to attach to and detach from the portion of the airplane engine at a proximate location to the airplane engine while the airplane engine is not running, the portion being configured to receive a direct manual adjustment from a user while the airplane engine is running and while the user is in direct physical contact with the portion;
• a second operative end which, while the airplane engine is running, is configured to obtain user input at a distal location to the airplane engine to provide a remote adjustment to the portion of the airplane engine through the first operative end in place of the direct manual adjustment from the user, the proximate location and the distal location being separated by at least two feet to enable a user to provide the user input at a relatively safe distance from the airplane engine;
• a driver which forms the first operative end, the driver being configured to come into direct physical contact with the portion of the airplane engine upon attachment of the first operative end to the portion of the airplane engine;
• a controller which forms the second operative end, the controller being configured to receive the user input;
• and
• a coupler which links the controller to the driver to convey the user input from the controller to the driver to remotely adjust the portion of the airplane engine from an initial setting to a new setting through the driver and the coupler
• wherein the portion of the airplane engine includes a mechanical linkage;
• wherein remote adjustment of the portion of the airplane engine from the initial setting to the new setting by the remote adjuster involves a change in size of the mechanical linkage to tune operation of the airplane engine.
