Where Can Locations for Vor Test Facilities Be Found

You need to make sure that your IFR equipment is checked and inside specific tolerances earlier you take off. Hither's what you need to know earlier your next flight. ..

VOR Checks

If you're planning to use your VOR receiver, the receiver must exist checked inside the preceding thirty days of the IFR flight (14 CFR 91.171). This goes for every IFR certified airplane, regardless of size. If there's something incorrect with your navigation receiver, it's better to know early on before you find yourself flying miles off-course.

Here are a few ways you can become this required cheque washed:

• VOT Signal: With a VOT, you can check the VOR accuracy from your airplane before takeoff. So what is a VOT? It's an canonical VOR test signal, and it's located on an airdrome. Non all airports accept VOTs, so yous'll need to check the chart supplement to run across if your airdrome has 1. If your airport does take a VOT, hither's what to do:
  • Tune your VOR to the VOT signal.
  • Set the course selector to 0 degrees, and the rail indicator should exist centered.
  • The TO-FROM indicator should read FROM.
  • Next, set the course selector to 180 degrees
  • The TO-FROM indicator should read TO, and the track bar should and then exist centered.
  • The maximum indicated bearing error is plus or minus iv degrees.


• VOR Checkpoint: Many airports take VOR checkpoint signs that are located about a taxiway, ramp or runup area. These signs indicate the exact indicate on the drome where at that place is sufficient signal force from a VOR to check the aircraft's VOR receiver against the radial designated on the sign. To use a VOR checkpoint, only follow the instructions on the sign.
  • The maximum indicated begetting error is plus or minus 4 degrees.


• Dual VOR Bank check: This is oft times the easiest cheque to accomplish, as long as you accept 2 VOR receivers. To bank check dual VOR receivers confronting 1 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 fault is 4 degrees.


• Airborne VOR Check: VOR equipment can besides be checked for accurateness in flying. To accomplish an airborne VOR check:
  • Select a VOR radial that lies along the centerline of an established VOR airway.
  • Select a prominent basis point along the selected radial preferably more than than 20 nautical miles from the VOR ground facility and maneuver the aircraft directly over the point at a reasonably low altitude.
  • Note the VOR begetting indicated by the receiver when over the footing signal.
  • The maximum indicated begetting error is plus or minus six degrees.

Recording Your VOR Bank check

Once your check is done, yous need to record it. Here's what the FARs require:

• Each person making the VOR operational bank check, as specified in paragraph (b) or (c) of this section, shall enter the engagement, place, bearing fault, and sign the aircraft log or other record. In addition, if a test signal radiated by a repair station, equally specified in paragraph (b)(ane) of this section, is used, an entry must be made in the aircraft log or other record past the repair station certificate holder or the document holder'due south representative certifying to the bearing transmitted by the repair station for the check and the engagement of transmission.

RNAV Accuracy

GPS and RNAV make IFR flying a whole lot easier than traditional VOR navigation. At that place are some checks yous demand to perform prior to takeoff to ensure your data is accurate for GPS as well:

• System Initialization: As yous power upwards your avionics, check to make certain the navigation database is updated and that the aircraft's electric current position is accurate.
• Flight Plan Check: Review your programmed flight program in comparison to charts and your IFR clearance. Ensure that naught is missing from the navigation database.
• RAIM Prediction: If y'all don't have a WAAS receiver, and you lot're planning to fly on an RNAV route or united states of america an RNAV/GPS arroyo, yous should complete a RAIM prediction on your equipment.

Finding Bug Is Improve On The Basis Than In The Air

Everyone has plant some type of equipment or database problem on an airplane. And obviously, information technology's better to find these problems on the footing than in the clouds under IFR. Do a thorough preflight bank check, and you'll be good to go in the air.
