7.2.2 STRUCTURAL TEMPERATURE INDICATOR
A structural temperature indicator, installed on the spar bridge, indicates when the
structural temperature limitation is exceeded (Refer to 2.16.7 - TEMPERATURE LIMITS).
Airplanes with other than white undersides have an additional structural temperature
indicator installed adjacent to the fuel drains. The indicator need only be checked if the
OAT exceeds 38 °C (100 °F).
The indicator is accessed by lifting the flap between the two seatback cushions. The
indicator is visible through the cut out in the seat shell backs (see Figure 2).
At temperatures below the 54 °C (129 °F) limit, the indicator appears all red with a faint
indication of "55" (°C). At temperatures exceeding the 54 °C (129 °F) limit, the indicator
displays a clearly contrasting red "55" (°C) on a black background (see Figure 1).
NOTE
At temperatures approaching the limit, the background will
progressively darken prior to turning black; this indicates
acceptable temperatures.
