4.3. STRUCTURAL TEMPERATURE INDICATOR
A structural temperature indicator, installed on the spar bridge, indicates when the structural
temperature limitation is exceeded (refer to Section 2.17). The indicator need only be checked
if the OAT exceeds 38o C (100o F).
The indicator is accessed by lifting the flap between the two seat-back cushions. The indicator
is visible through the cut out in the seat shell backs (see Figure 2).
At temperatures below the 55o C (131o F) limit, the indicator appears all red with a faint
indication of “55” (o C). At temperatures exceeding the 55o C (131o F) limit, the indicator
displays a clearly contrasting red “55” (o 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.
NOTE
Aircraft with other than white undersides have an additional structural temperature indicator installed adjacent to the fuel drains.
Red “55” on black background All red indicates that structural
