Abstract

Trim adjustment devices 20, 30, 40 at least include trim control switches 21, 31, 41 for performing a trim adjustment; acquisition sections 22, 32, 42 for acquiring a designated value for a position designated through the operation of the switches 21, 31, 41 ; and converting sections 23, 33, 43 for converting the designated value to a converted designated value expressed in different units. The switches 21, 31, 41 operate at a changeable rate in which the designated value changes at a prescribed amount of change per unit time, the prescribed amount of change expressed in units of the designated value before the conversion. The sections 23, 33, 43 converts the designated value to the converted designated value expressed in minimum units (0.1 UNIT) based on the product of the changeable rate and a click time period required for clicking the switches 21, 31, 41 once.

Claims (33)

1. A trim adjustment device comprising:

a trim control switch for being operated to perform a trim adjustment for setting a neutral position of a control surface controlling section for controlling a control surface or a current position of the control surface;

a designated value acquisition section for acquiring a designated value for a position designated through the operation of the trim control switch;

a converting section for performing a unit conversion of the designated value to a converted designated value expressed in different units; and

a display for displaying the converted designated value provided by the converting section;

wherein the trim control switch operates at a changeable rate in which the designated value changes at a prescribed amount of change per unit time, the prescribed amount of change being expressed in units of the designated value before the unit conversion; and

wherein the converting section performs the unit conversion of the designated value to the converted designated value expressed in minimum units, the minimum units being based on the product of the changeable rate and a click time period required when the trim control switch is clicked once.

2. The trim adjustment device according to claim 1 , further comprising a rounding section for rounding the converted designated value provided by the converting section in such a manner that fractions of the converted designated value less than the minimum units are rounded, and

wherein the display displays the converted designated value which is rounded by the rounding section.

3. The trim adjustment device according to claim 2 , wherein the rounding section rounds off the converted designated value.

4. An aircraft comprising:

a steering member having a control surface; and

the trim adjustment device according to claim 1 .

5. An aircraft comprising:

a steering member having a control surface; and

the trim adjustment device according to claim 2 .

6. An aircraft comprising:

a steering member having a control surface; and

the trim adjustment device according to claim 3 .

7. A method of performing the trim adjustment according to claim 1 in which a neutral position of a control surface controlling section for controlling a control surface or a current position of the control surface are set, the method comprising:

performing a unit conversion of a designated value for a position for the trim adjustment to a converted designated value, wherein the designated value for the position for the trim adjustment is designated through the operation of a trim control switch, wherein the trim control switch operates at a changeable rate in which the designated value changes at a prescribed amount of change per unit time, and wherein the converted designated value is expressed in minimum units, the minimum units being based on the product of the changeable rate and a click time period required when the trim control switch is clicked once; and

displaying the converted designated value.

8. A trim adjustment method comprising:

performing a trim adjustment for setting a neutral position for controlling a control surface or a current position of the control surface;

acquiring a designated value for a position designated through performing the trim adjustment;

performing a unit conversion of the designated value to a converted designated value expressed in different units; and

displaying the converted designated value,

wherein performing the trim adjustment occurs at a changeable rate in which the designated value changes at a prescribed amount of change per unit time, the prescribed amount of change being expressed in units of the designated value before the unit conversion; and

wherein performing the unit conversion comprises performing the unit conversion of the designated value to the converted designated value expressed in minimum units, the minimum units being based on the product of the changeable rate and a click time period required when a trim control switch is clicked once.

9. The trim adjustment method according to claim 8 , further comprising:

rounding the converted designated value in such a manner that fractions of the converted designated value less than the minimum units are rounded, and

displaying the converted designated values comprises displaying the converted designated value which is rounded.

10. The trim adjustment method according to claim 9 , wherein rounding rounds off the converted designated value.
