3.1.5

Unsteady flight

unsteadyflightstate

Flight (3.1.2) at least one variable over time of flight Changes can not be ignored.

3.1.6

Reference flight status referenceflightstate in a given study, the reference flight condition.

Note 1. In most cases, the reference flight condition taken as a constant flight (3.1.3) or quasi-steady flight (3.1.4).

Note 2. For a period of study, usually with flight like the previous time period State (3.1.2) as a reference.
