Defining age
The age of an aircraft in Fleets Analyzer is defined as follows:
- If the aircraft at the query date has the status “Retired” or “Written Off”, the aircraft age will be null (shown as “-” on detail grids).
- In all other cases, the aircraft age will be the number of years between the query date and the Aircraft Start of Life Date.
- The Aircraft Start of Life Date will be one of the following dates (in order of precedence, i.e. the first in the list that is available will be used), rounded nearest to one decimal place:
- First Flight Date.
- The earliest date the aircraft reached either status “In Service” or “Storage”.
- If the Aircraft Start of Life Date is null, the aircraft age will be null (shown as “-” on detail grids) e.g. for aircraft with a status of “On order”.
- If the Aircraft Start of Life Date is greater than the query date, the aircraft age will be null (shown as “-” on detail grids)
