Hours recording
Good Question! I worked in a foreign Air Force which tried to go over to 'decimal' hours with flights recorded to the nearest 3 minutes. This matter was raised some time ago on this Forum and a link was posted to a programme which enabled the use of a calculator to be used to add hours and minutes, in the 60 minutes per hour format. If it is your log book I guess it is up to you but if it is an official thing like an RAF Form 414 or something used by the authorities, it may not be up to you how you record the hours. If you are looking for official use and recognition of your hard earned hours you may have to comply with some approved protocol for the recording of them.
