Has anyone heard of 'representative' surfaces recently? Came across my CBT screen the other day, not sure what they meant (poorly translated).
our ops manual says the following:
Aircraft representative surfaces are those pre-approved surfaces which can be readily and clearly observed by flight crew during day and night operations, and which are suitable for making a reasonable judgment regarding whether or not frozen contaminants are adhering to other aircraft critical surfaces. Examination of one or more representative aircraft surfaces may be used for the Pre-Takeoff Contamination Check; if a tactile examination is not required. When identifying a representative surface the following guidelines are considered:
- The surface can be seen clearly to determine whether or not frozen contaminants are forming or accumulating on the surface.
- The surface should be unheated.
- During the deicing/anti-icing procedure, the representative surface should be one of the first surfaces treated with deicing/anti-icing fluid
