A mirror for an airplane is provided to recognize whether an engine, a main wing, and a landing gear are normally operated without installing an electronic inspection apparatus. A mirror for an airplane includes a mirror(10), vertical rotary shafts(20), a first fixed shaft(30), horizontal rotary shafts(40), a second fixed shaft(50), a luminous intensity detection member, and a transmissivity adjustment member. The mirror is disposed in a cockpit. The vertical rotary shafts rotate the mirror in a horizontal direction. The first fixed shaft is disposed between the vertical rotary shafts. The horizontal rotary shafts are disposed perpendicular to the vertical shafts. The second fixed shaft is installed between the horizontal rotary shafts. The luminous intensity detection member includes an optical sensor and an amplifier. The transmissivity adjustment member includes a resistor, a switch, a conversion part, and a power supply. |
