What information must be recorded for VOR checks?
In the absence of any other way to check your VOR, you may conduct a check airborne. The tolerance is 6 degrees. The checks must be logged with the date, location, bearing error, and signature. These regulations are found in FAR 91.171.
What regulation discusses check a VOR for IFR operations?
14 CFR § 91.171 – VOR equipment check for IFR operations.
Is VOR check required for ILS?
This regulation does not apply to an ILS approach. You are right is saying that “the VOR system of radio navigation” refers to actual VORs. If the flight is conducted using GPS to an ILS approach then you aren’t using VOR for navigation. It does not matter that ILS uses the same instrument display.
Is a VOR check required for IFR?
VOR Receivers are required to be checked every 30 days for IFR Flight Operations. However, it is also important for VFR Pilot’s to check their aircraft’s VOR Receivers.
What are the different types of VOR checks?
VOR Checks
- VOT Signal: With a VOT, you can check the VOR accuracy from your plane before takeoff.
- VOR Checkpoint: Many airports have VOR checkpoint signs that are located near a taxiway, ramp or runup area.
- Dual VOR Check: This is often times the easiest check to accomplish, as long as you have 2 VOR receivers.
How do I know if I have dual VOR?
To check dual VOR receivers against one another:
- Tune both NAV radios to the same VOR facility.
- Center the needles of each VOR receiver with a “TO” indication.
- Note the indicated bearings to the station from each receiver.
- The maximum indicated bearing error is plus or minus 4 degrees.
What are the limitations of the VOR?
VOR Limitations: The range varies proportionally to the altitude of the receiving equipment. This means the farther from the station, the higher you must be. See Standard Service Volume (SSV) for more range restrictions.
How do I check my VOR facilities?
How can I find information about VOR Test Facilities (VOT)? Locations of airborne check points, ground check points, and VOTs are published in the A/FD. To find what you need, go to the DOCUMENTS page and select CATALOG in the upper right corner.
What does 14 CFR 91.171-vor equipment check?
14 CFR 91.171 – VOR equipment check for IFR operations. Both systems shall be tuned to the same VOR ground facility and note the indicated bearings to that station. The maximum permissible variation between the two indicated bearings is 4 degrees.
How does a VOR operational check take place?
(d) Each person making the VOR operational check, as specified in paragraph (b) or (c) of this section, shall enter the date, place, bearing error, and sign the aircraft log or other record.
Can a dual VOR check be done on an airplane?
The FAA allows for one more method of checking a VOR receiver, and you may do this if you have two separate receivers in your aircraft (they can share an antenna). A dual receiver check is valid if you have two separate receiver units in your aircraft. They can have a common antenna but the actual receivers must be separate.
What’s the best way to check your VOR receiver?
You may also make your own airborne check by looking at the charts and picking a significant geographic landmark under a VOR airway. Fly over the landmark and note the azimuth that your aircraft VOR receiver indicates. It should be within 6 degrees of the annotated airway azimuth.
