Final answer:
The FDME 'Upslip' extension times and durations aren't explicitly defined. They depend on the judgment of a flight surgeon considering the person's health condition and recovery rate. Typically, one extension for a further six months may be granted after a detailed case reevaluation.
Step-by-step explanation:
The FDME 'Upslip' (DD Form 2992) is a critical document in the medical field, particularly in aviation medicine, because it guides flight and duty restrictions. The length of time or the number of instances that an FDME 'Upslip' can be extended isn't explicitly stated in the standard guidelines. Instead, it is contingent upon the judgment of a competent medical authority, typically a flight surgeon, who assesses the individual's health and eligibility for duty.
It is a subjective process dependent on the individual's specific circumstances, nature of the ailment or condition and their rate of recovery. However, normally, one extension for a period of an additional six months may be granted by the appointing authority after a thorough reevaluation of the case.
