b.  
Aircraft performance will vary considerably within the defined climates. It is not intended that any one stated performance should be achievable throughout the whole envelope of conditions but rather that sufficient performance data should be scheduled for an operator to determine the performance which will be achieved in particular conditions.

c.  
The climatic conditions given are conditions of the free atmosphere. The temperatures achieved in an aircraft in these atmospheric conditions may be considerably higher. In the absence of precise information as to the surface finish, ventilation and type of engine, etc., the following maximum ambient temperatures should be assumed:–

Temperate and Arctic Tropical
i.  in the interior of an aircraft; 45°C 60°C
ii.  for portions of the outer covering liable to be in the sun and parts attached directly to such covering; 55°C 80°C
iii.  in an engine compartment for parts not attached
