Aircraft applicability: Aeroplanes & Helicopters

Additional considerations:

The above is applicable only to those aircraft where the clock has no implication on other equipment, e.g. FDR; otherwise the effects on such other systems must be considered.

If the above is verified and on the basis that the timepiece required does not need to be approved, an accurate pilot’s wristwatch which indicates hours, minutes and seconds would be acceptable.
