What is an unserviceable Navaid?
If a NAVAID fails or is removed from service prior to all airspace and procedural dependencies being removed, a NOTAM will be published to inform pilots of the NAVAID being Unserviceable (U/S) or Out of Service (OTS). Pilots must check NOTAMs to ensure any NAVAID required for the flight is in service.
How is RVR measured?
Measurement. Originally RVR was measured by a person, either by viewing the runway lights from the top of a vehicle parked on the runway threshold, or by viewing special angled runway lights from a tower at one side of the runway. The number of lights visible could then be converted to a distance to give the RVR.
What does unserviceable mean FAA?
Out of Service
Out of Service. Added: Unserviceable “U/S” to OUT OF SERVICE definition. 1−4−6. Modified definition: NOTAM D issued to point to additional aeronautical information. When pointing to another NOTAM, the keyword in the pointer NOTAM must match the keyword in the original NOTAM.
What are SAA NOTAMs?
Special Activity Airspace
4) SAA NOTAMs Special Activity Airspace NOTAMs are issued when the airspace is active outside its normally published times and when required by the published schedule.
Are NDBs still used?
NDBs are rare, but still part of a well-rounded pilot’s training. Now, to nearly everyone’s gratitude, most NDB approaches have been decommissioned—and replaced by much more accurate, simpler RNAV GPS-based procedures.
What is tacan in aviation?
Definition of TACAN : a system of navigation that uses ultrahigh frequency signals to determine the distance and bearing of an aircraft from a transmitting station.
What does RVR 6 6 mean?
RVR 6/6/6 means all three transmissometers are reporting 600 RVR. Departing with 6/m/6 is allowed.
What does RVR 5 mean?
RVR 5 is now the lowest authorized take-off minimum based upon outside visual references. • High intensity runway lighting (HIRL) is required for take-off operations less than RVR 10. The following requirements and restrictions apply to the use of RVR values below RVR 16: a.

What does it mean to preflight a PDF file?

Can a pilot request to deviate from ADS-B rule?
Pilots/operators using aircraft that do not meet ADS-B Out equipage or performance requirements may request an authorization to deviate from the rule to access ADS-B Out rule airspace. The FAA has developed the ADS-B Deviation Authorization Preflight Tool (ADAPT) to manage these authorization requests.
How is a flight preceded by a preflight inspection?
Every flight is preceded by a preflight inspection of the airplane. To inspect the airplane, we will follow a flow pattern in the same sequence before each flight.
Do you need adapt for ADS-B deviation authorization?
The FAA has developed the ADS-B Deviation Authorization Preflight Tool (ADAPT) to manage these authorization requests. In order to be considered for an ADS-B deviation authorization with ADAPT, requests must meet the following criteria: Aircraft must be equipped with an operational transponder and operational altitude encoder (e. g., Mode C)
