摘要:
A guidance apparatus mounted on the belly of a tanker aircraft for providing visual indications to the pilot of the receptor aircraft with respect to the approaching operation to carry out the refueling by means of a refueling boom is provided. The guidance apparatus comprises light emitting devices (11) including modules of light emitting diodes (LEDs) and control devices (41, 61) for supplying current to them that include dimming control units (45, 65) for controlling the intensity of the light emitted by said light emitting devices (11) by means of a dimming signal depending on a dimming voltage ( Vdim ). The dimming control units (45, 65) are adapted to provide to the light emitting devices (11) a pulse-exponential amplitude modulated dimming signal ( Vref2 ) so that the light intensity can be properly controlled in all visibility conditions.
摘要:
Maintenance system of an installation (10) of a vehicle, such a vision installation of a tanker aircraft, comprising a maintenance equipment (41; 47, 46) having means for performing the maintenance activities by means of an interactive communication between said maintenance equipment (41; 47, 46) and said installation (10), in which the installation (10) uses a first communication interface and it is provided with an I/O connector (31); the maintenance equipment (41; 47, 46) is provided with wireless connection means using a second communication interface; and the system also comprises a converter device (33) for said first and second communication interfaces connected to said I/O connector (31). The invention also refers to a method for performing the maintenance of said installation (10).
