How do you do a dual VOR check?

To check dual VOR receivers against one another:

1. Tune both NAV radios to the same VOR facility.
2. Center the needles of each VOR receiver with a “TO” indication.
3. Note the indicated bearings to the station from each receiver.
4. The maximum indicated bearing error is 4 degrees.

What is the maximum permissible error on a dual VOR check?

The maximum permissible variation between the two indicated bearings is 4 degrees.

How do you check Airborne VOR?

With an Airborne VOR check: The Pilot must position the airplane over the designated location….How the check is done:

1. Tune and Identify the VOT.
2. Twist the OBS Knob to center the CDI Needle.
3. Check for proper TO/FROM Indication.
4. The radial selected must be within:
5. +/- 4 degrees of 360 or 180.

Is a VOR check required for ILS?

The FARs require a check of the VOR receiver before IFR flight: §91.171 VOR equipment check for IFR operations.

How can I test my VOR?

VOR is generally tested by turning the patient’s head on their long axis and observing for the doll’s eyes response (DOLL). The eyes deviate opposite to the direction of head rotation. A possibly related maneuver has been used in infants as a neurologic test.

Is a VOR required for instrument flight?

The federal aviation regulations, specifically 14 CFR 91.205, detail the equipment needed for different flight conditions, such as day VFR, night VFR, IFR, etc. The answer is obviously no for the pilot flying IFR solely (from a legal perspective) in reliance on the VORs.

How do I perform a dual receiver VOR check?

Steps to conducting a dual receiver VOR check: 1 Tune both receivers to a nearby VOR station. 2 Identify the station in both receivers by turning up the volume and verifying the Morse code or voice identifier. 3 Compare the OBS settings for both receivers with the needle centered. They must be within four degrees of each other. More

Can I Check my VOR while on the ground?

You can also check your receiver while on the ground at certain airports using a dedicated VOR test facility or a designated VOR ground checkpoint, both found in the FAA Chart Supplement. Tolerance is 4 degrees. In the absence of any other way to check your VOR, you may conduct a check airborne.

Can a VOR equipment check for IFR operations?

14 CFR § 91.171 – VOR equipment check for IFR operations. prev | next. § 91.171 VOR equipment check for IFR operations. (a) No person may operate a civil aircraft under IFR using the VOR system of radio navigation unless the VOR equipment of that aircraft -. (1) Is maintained, checked, and inspected under an approved procedure; or.

What do you need to know about VOR logs?

The log must contain the date, location, bearing error, and signature of the pilot conducting the check. If you’re an IFR pilot using VORs for navigation, you must check your VOR receiver within 30 days preceding an IFR flight, and log the check. You may check two receivers against each other if your aircraft has two separate units.
