5 VOR Questions Every Pilot Should Be Able to Answer (Private Pilot Checkride Guide)

5 VOR Questions Every Pilot Should Be Able to Answer (Private Pilot Checkride Guide)

By Timor M., CFII

If you’re preparing for your private pilot checkride, there’s a good chance your examiner will spend time on VORs. Even in the age of GPS and glass cockpits, VOR knowledge remains a core skill—and a reliable fallback when other technology fails.

This guide covers 5 commonly asked VOR questions on the checkride, along with clear, checkride-ready answers and practical explanations.

Why VORs Still Matter (Even for VFR Pilots)

Before diving into the questions, it’s important to understand why this topic still shows up consistently:

  • Backup navigation: GPS can fail. VORs provide a ground-based, independent system.
  • Situational awareness: Understanding radials improves your mental map of airspace.
  • ATC integration: You may still receive VOR-based instructions (e.g., “join the 270 radial”).
  • Checkride standards: The ACS still requires VOR knowledge and usage.

Bottom line: Even if you primarily fly with GPS, you’re expected to understand and use VORs competently.

1. What is a VOR and how does it work?

Checkride-Ready Answer:

A VOR (VHF Omnidirectional Range) is a ground-based navigation aid that transmits signals in all directions. Aircraft receivers interpret these signals to determine their position relative to the station in terms of radials, which are magnetic bearings from the station.

Key Points to Understand:

  • VORs operate in the 108.0–117.95 MHz range
  • Each radial represents a magnetic bearing FROM the station
  • The aircraft determines its position by comparing two signals:
    • A reference signal
    • A variable signal

Common Follow-Up:

Q: Are radials based on magnetic or true north?
A: Magnetic north.

2. What does it mean to “track a radial” vs “intercept a radial”?

Checkride-Ready Answer:

  • Intercepting a radial means maneuvering the aircraft to join a specific radial.
  • Tracking a radial means maintaining that radial once established, correcting for wind drift as needed.

Practical Example:

If ATC says, “Intercept the 180 radial,” you:

  1. Turn to intercept the radial at an angle (typically 30–45°)
  2. Once established, adjust heading to maintain the radial (tracking)

What the Examiner is Looking For:

  • Understanding of wind correction
  • Ability to distinguish between getting to vs staying on a course

3. How do you know if you’re flying TO or FROM a VOR?

Checkride-Ready Answer:

You determine TO/FROM using the indicator flag and by ensuring the selected course makes sense for your position relative to the station.

Key Technique:

  • Twist → Turn → Track
    1. Twist the OBS to center the CDI with a FROM indication
    2. That gives you the radial you’re on
    3. Select the desired course and confirm TO/FROM

Important Concept:

  • The VOR always tells you your position relative to the station—not your heading.

Common Trap Question:

Q: Can you have a centered CDI with a TO indication and be flying away from the station?
A: Yes—if you’re flying the wrong direction on the selected course.

4. What is reverse sensing?

Checkride-Ready Answer:

Reverse sensing occurs when the OBS is set to a course that doesn’t match the desired direction of flight, causing the CDI to give opposite indications.

Example:

  • You’re flying TO the station
  • But you set a FROM radial
  • The CDI will indicate the opposite of what you should do

How to Avoid It:

  • Always ensure:
    • Proper TO/FROM indication
    • Course aligns with your intended direction

Examiner Insight:

They want to see that you understand why the needle behaves incorrectly—not just that it does.

5. How do you check VOR accuracy (VOT check)?

Checkride-Ready Answer:

A VOR accuracy check ensures the system is within allowable limits before use under IFR, but it’s also good practice for all pilots.

Acceptable Methods:

  • VOT (VOR Test Facility):
    • Tune published frequency
    • CDI should center on 0° FROM or 180° TO
    • Allowable error: ±4°
  • Airborne checkpoint: ±6°
  • Ground checkpoint: ±4°
  • Dual VOR comparison: ±4°

Key Requirement:

  • IFR pilots must log the check, but all pilots should understand the concept.

Final Thoughts: Mastering VORs for Your Checkride (and Beyond)

VOR questions are not just academic—they test your ability to think spatially, interpret instruments, and maintain situational awareness.

Even if you plan to rely heavily on GPS, your examiner is evaluating whether you can:

  • Navigate without automation
  • Interpret raw data
  • Maintain control and awareness under uncertainty

If you can confidently answer and apply these five questions, you’re in a strong position for your checkride.
