INDICATING SYSTEM -WING UNDERBODY COMPONENT LOCATIONS
Wing Underbody Locations
There are two manifold pressure sensors on the airplane. One attaches to airplane structure forward and outboard of the right ECS bay near the primary jack point for the wing. The other one is opposite, on the left side of the airplane.
There are two manifold flow sensors in the distribution system ducts. One is in the left wing under the fixed leading edge. The other one is in the right wing under the fixed leading edge.
Training Information Point
You remove the access panel 191SL (left jack point access panel) to get access to the left manifold pressure sensor. You remove access panel 192SR (right jack point access panel) to gain access to the right manifold pressure sensor.
You open access panel 511JB on the left wing to get access to the left manifold flow sensor. You open access panel 611JB on the right wing to get access to right manifold flow sensor.

INDICATING SYSTEM -MANIFOLD PRESSURE SENSOR
Purpose
The manifold pressure sensors monitor the pressure in the air supply distribution system.
Location
There are two manifold pressure sensors. One attaches to airplane structure forward and outboard of the left ECS bay near the distribution duct. The other one is opposite, on the right side of the airplane.
Physical Description
The pressure sensor is an electronic strain gage type. The sensor has these parts:
*
Housing
*
Electrical connector
*
Vent hole (3)
*
Pneumatic connector.
Training Information Point
You attach the sensor with band clamps around the housing. Do not attach the sensor so that the clamps cover the vents.
You remove the access panel 191SL (left wing primary jack point access panel) to get access to the left manifold pressure sensor. You remove access panel 192SR (right wing primary jack point access panel) to get access to the right manifold pressure sensor.

INDICATING SYSTEM -INTERMEDIATE PRESSURE SENSOR
Purpose
The intermediate pressure sensor (IP) monitors the pressure in the HP/IP manifold.
Location
There is one IP sensor on each engine fan case at the 3:00 position.
Training Information Point
You open the right fan cowl to get access to the IP sensor.

INDICATING SYSTEM -MANIFOLD FLOW SENSOR
Purpose
The manifold flow sensor monitors the flow rate of the air in the air supply distribution system.
Location
There are two manifold flow sensors in the distribution system ducts. One is in the left wing under the fixed leading edge. The other one is in the right wing under the fixed leading edge.
Physical Description
The sensor is an electrically heated unit. The sensor has these parts:
*
Housing
*
Electrical connector
*
Resistive temperature detector
*
Internal heater (not shown).
Training Information Point
You open access panel 511JB on the left wing to get access to the left manifold flow sensor. You open access panel 611JB on the right wing to gain access to right manifold flow sensor.
