This idea may have been raised previously.
Suggest that the TTIS be included in the Flight Records as a custom field which can be added to both the Flight Details and Flight Leg sections, and which can be referenced by calculated fields. E.g. if one wanted to display TTIS at start and again at shutdown, one would create a calculated field that added flight time to Start TTIS for the latter.
Carry forward aircraft TTIS and cycles in Flight Records
A number of clients have requested that certain aircraft-related values are carried forward from one flight record entry to the next, so as to facilitate a running total per aircraft rego. Most notably, these include total airframe time (MR time?) and cycles such as landings and engine starts.
