FAA Navigation Aids (NAVAIDs) 1 — Questions and Answers
Question 1: On a sectional chart, what information is found in a VOR data box?
- Name, frequency, Morse code identifier, and channel (Correct answer)
- Name, latitude/longitude only
- Name, elevation, and ATIS frequency
- Runway lengths and fuel availability
Correct answer: Name, frequency, Morse code identifier, and channel
A VOR data box on a sectional chart contains the station name, frequency, Morse code identifier, and TACAN channel number (if applicable).
Question 2: What is the standard frequency range for VOR stations shown on sectional charts?
- 108.0–117.95 MHz (Correct answer)
- 190–535 kHz
- 225–400 MHz
- 329.15–335.00 MHz
Correct answer: 108.0–117.95 MHz
VORs operate in the VHF band between 108.0 and 117.95 MHz, which is reflected in the frequency listed in every VOR data box on sectional charts.
Question 3: On a sectional chart, a VOR symbol with a surrounding compass rose indicates what?
- The VOR has ILS capability
- The VOR is a terminal VOR (TVOR)
- The VOR has DME collocated
- The VOR radials can be used for navigation (Correct answer)
Correct answer: The VOR radials can be used for navigation
The compass rose printed around a VOR on a sectional chart is aligned to magnetic north and shows the orientation of the VOR's radials for navigation planning.
Question 4: On a sectional chart, what does 'D' in a VOR box indicate?
- The VOR is decommissioned
- DME (Distance Measuring Equipment) is collocated (Correct answer)
- Directional capability only
- Dual frequency operation
Correct answer: DME (Distance Measuring Equipment) is collocated
The letter 'D' following 'VOR' in the data box (making it 'VOR-DME' or 'VORTAC') indicates that Distance Measuring Equipment is co-located with the VOR.
Question 5: What does a VORTAC symbol represent on a sectional chart?
- A VOR used only for TAC aircraft
- A VOR collocated with a TACAN military beacon providing DME to civil aircraft (Correct answer)
- A terminal VOR with automatic ATIS
- A VOR with terrain avoidance capability
Correct answer: A VOR collocated with a TACAN military beacon providing DME to civil aircraft
A VORTAC is a VOR collocated with a military TACAN station, providing civil pilots with VOR bearing information and DME distance from the TACAN component.
Question 6: What does an 'H' in the navigation aid box on a sectional chart indicate?
- High-altitude VOR (usable above 18,000 feet MSL) (Correct answer)
- Helicopter-only NAVAID
- Has HIWAS weather broadcast
- High-intensity lighting on runway
Correct answer: High-altitude VOR (usable above 18,000 feet MSL)
An 'H' designation in the NAVAID box indicates a high-altitude VOR with a service volume usable between 18,000 and 60,000 feet MSL at ranges up to 130 nm.
