Takeoff, alternate and surface information
- Takeoff minimums are published for KNUW. Standard is 1 statute mile visibility for one and two engine aircraft (½ mile for more than two) unless this section says otherwise; Part 91 operators are not bound by them but the obstacle notes apply to everyone.
- Whidbey Island NAS (Ault Field) has an obstacle departure procedure (ODP): the charted way to clear terrain and obstacles after takeoff in instrument conditions. ATC does not assign it; under Part 91 it is recommended rather than required, and it is what you fly when no SID or radar vectors have been given.
- A diverse vector area (DVA) is established, so ATC can issue radar vectors below the minimum vectoring altitude right after departure.
