Aircraft elevator feel computer test apparatus

An aircraft Elevator Feel Computer (EFC) test kit, comprising:

• a rigid case having:
• a bin;
• a second cover attached to the bin by a second hinge;
• a second latch to selectably secure the second cover to the bin in a closed configuration;
• a test kit case handle attached to the rigid case;
• and
• a pair of wheels attached to the rigid case, wherein the rigid case fits in a space that is about 32 inches long, about 21 inches wide, and about 12 inches tall to facilitate setup of the EFC test kit in an aft galley of an airliner;
• a test box including:
• a housing having a base;
• a first cover attached to the base;
• a first hinge to attach the first cover to the base;
• a latch to selectably secure the first cover to the base in a sealed configuration;
• a test box handle attached to the test box to facilitate lifting and carrying the test box, wherein the housing fits in a space that is about 14 inches long, about 12 inches wide, and about 6 inches tall to facilitate setup and operation of the test box in an aft galley of an airliner;
• an interface panel mounted on the base to define a base enclosure;
• an electrical power supply interface including a power on-off switch and an electrical connector for connecting the apparatus to an electrical power cable;
• a two-channel pneumatic pressure measurement subsystem including:
• a first air inlet connector disposed on an interface panel, the first air inlet connector to connect to a first visco drain in fluid communication with a first pitot probe;
• a second air inlet connector disposed on the interface panel, the second air inlet connector to connect to a second visco drain in fluid communication with a second pitot probe;
• a two-channel hydraulic pressure measurement subsystem including:
• a first electrical connector disposed on the interface panel, the first electrical connector to connect to a first hydraulic transmitter;
• a first electrical circuit defined within the base enclosure to electrically connect the first electrical connector to a first hydraulic pressure display to indicate a first hydraulic pressure;
• a second electrical connector disposed on the interface panel, the second electrical connector to connect to a second hydraulic transmitter;
• and
• a second electrical circuit to electrically connect the second electrical connector to a second hydraulic pressure display to indicate a second hydraulic pressure;
• the electrical power cable;
• a pitot hose assembly including:
• an air input hose;
• a T-fitting connected to the air input hose;
• a first pitot adapter hose to connect the T-fitting and a first pitot probe adapter, wherein the first pitot probe adapter is to connect to the first pitot probe wherein the first pitot probe adapter is to reversibly form a pressure tight connection with the first pitot probe;
• and
• a second pitot adapter hose to connect the T-fitting and a second pitot probe adapter, wherein the second pitot probe adapter is to connect to the second pitot probe, wherein the second pitot probe adapter is to reversibly form a pressure tight connection with the second pitot probe wherein a pressurized air delivery system is to deliver pressurized air simultaneously to the first pitot probe and the second pitot probe via the pitot hose assembly;
• a first pressure return hose assembly to fluidically connect the first air inlet connector to the first visco drain and a second pressure return hose assembly to fluidically connect the second air inlet connector to the second visco drain;
• a first hydraulic signal cable to connect the first electrical connector to the first hydraulic transmitter, and a second hydraulic signal cable to connect the second electrical connector to the second hydraulic transmitter;
• a hose grip assembly having a suction cup and hose retainer to support hoses in an organized arrangement during setup and operation of the test box;
• the first pitot probe adapter and the second pitot probe adapter;
• a first pretest pin and a second pretest pin for installing in the first pitot probe adapter or the second pitot probe adapter to isolate a suspected leak during operation of the test box;
• the first hydraulic transmitter and the second hydraulic transmitter;
• and
• a bottle of lubrication fluid for lubricating the first pitot probe adapter and the second pitot probe adapter, wherein the elements of the test kit, other than the rigid case, fit entirely within the rigid case when the first cover is latched to the bin in the closed configuration.
