2. Magnetic switchable device - Wikipedia

   en.wikipedia.org/wiki/Magnetic_switchable_device

   A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...

3. Automatic direction finder - Wikipedia

   en.wikipedia.org/wiki/Radio_Magnetic_Indicator

   An ADF indicator with a fixed azimuth dial. The airplane is flying a 40° magnetic heading, while the station is 310° relative to the plane (called "relative bearing"). The magnetic bearing to the station in this case is 350°. The ADF indicators are a kind of navigational display consisting of a dial and a needle that rotates around the dial ...

4. Indicator (distance amplifying instrument) - Wikipedia

   en.wikipedia.org/wiki/Indicator_(distance...

   Ideal test indicator pushed. Prior to modern geared dial mechanisms, test indicators using a single lever or systems of levers were common. The range and precision of these devices were generally inferior to modern dial type units, with a range of 10/1000 inch to 30/1000 inch, and precision of 1/1000 inch being typical.

5. VHF omnidirectional range - Wikipedia

   The indicator may also include a glideslope pointer for use when receiving full ILS signals. A radio magnetic indicator (RMI) features a course arrow superimposed on a rotating card that shows the aircraft's current heading at the top of the dial. The "tail" of the course arrow points at the current radial from the station and the "head" of the ...

6. Aircraft compass turns - Wikipedia

   en.wikipedia.org/wiki/Aircraft_compass_turns

   A magnetic compass aboard an aircraft displays the current magnetic heading of the aircraft, i.e., the aircraft's directional orientation relative to the Earth's geomagnetic field, which has a roughly north-south orientation. The compass can be used in turns to verify the aircraft is travelling in the desired direction at the conclusion of a turn.

7. Gauge (instrument) - Wikipedia

   en.wikipedia.org/wiki/Gauge_(instrument)

   Dial indicator, also known as a dial test indicator, dial gauge, or probe indicator an instrument used to accurately measure small linear distances. Feeler gauge: a simple tool used to measure gap widths. Gauge block, (also known as a gage block, Johansson gauge, slip gauge, or Jo block) a precision ground and lapped length measuring standard.

8. Lens clock - Wikipedia

   en.wikipedia.org/wiki/Lens_clock

   Lens clock. A lens clock is a mechanical dial indicator that is used to measure the dioptric power of a lens.It is a specialized version of a spherometer.A lens clock measures the curvature of a surface, but gives the result as an optical power in diopters, assuming the lens is made of a material with a particular refractive index.

9. Flight instruments - Wikipedia

   These include the Horizontal Situation Indicator (HSI) and Attitude Director Indicator (ADI). The HSI combines the magnetic compass with navigation signals and a Glide slope. The navigation information comes from a VOR/Localizer, or GNSS. The ADI is an Attitude Indicator with computer-driven steering bars, a task reliever during instrument flight.
