What is specific routing?
A published specific routing to avoid obstacles under the departure procedure section of the obstacle departure procedure
What is a visual climb over airport?
A visual climb over airport procedure is a departure option for IFR aircraft operating in VMC equal to or greater than the specified visibility and ceiling to visually conduct climbing turns over the airfield to the published climb to altitude
Who may authorize the use of VCOA procedures?
The MAJCOM
What is a diverse vector area?
A diverse vector area is an assigned vector azimuth in lieu of obstacle departure procedure where the pilot departs based on headings assigned from ATC
Are specific ATC departure instructions considered radar vectors?
They are not radar vectors
Should wind drift corrections be applied to specific ATC departure instructions?
They should not be applied
If departure instructions conflict with the obstacle departure procedure or with terrain or obstacles in the direction of the departure what should be performed?
The pilot should query the controller
For Air Force pilots what takes precedence the obstacle departure procedure or ATC departure instructions?
The obstacle departure procedure. If ATC instructions conflict with this the pilot must query the controller’s line if unable to fly a standard instrument departure what should be placed in the flight plan? No Sid in the remarks section
What is required to fly a standard instrument departure?
ATC clearance
If radar vector or cleared off of an assigned SID with the instrument to prompt the pilot to resume the SID?
Expect to resume SID
What are vector SID’s?
Air traffic control provides radar navigation to a filed route, or fix on the standard instrument departure. Considered a hybrid approach to departure traffic flow
What is performance based navigation?
Specifies the required navigational performance necessary to attempt the approach such as accuracy, integrity, and functionality
What is the RNP specification?
The requirement for on board performance of navigating, monitoring, and alerting for a required approach
NAVAIDs may be identified via what to aspects?
They’re audible Morse code or their visual alphanumeric signal the
When utilizing a NAVAID to navigate what must be performed?
The station must be monitored either visually or aurally to ensure transmission of a stable signal
What are the two classes of integrity monitoring?
RAIM and aircraft autonomous integrity monitoring which uses internal onboard sensors
Approach waypoints are normally fly by waypoints but the missed approach waypoint and the missed approach holding waypoint are what kind of waypoint?
Fly over waypoints
There are how many GPS satellites?
24

The PIC
Off of Airways aircraft should fly no lower than what?
