The conditions of operation given above can, of course, act only as a general guide, for, as will be readily appreciated, the wide variations of temperature that may occur in one locality even during a single day would make impossible a literal application of the recom mendations. In general, however, if it is expected that the temperatures specified for the use of tropical or arctic grades of oil will be met at ground level during the normal course of opera ion of the aircraft at that particular time, then the appropriate grade of oil should be used.
