FAA Navigation Aids (NAVAIDs) 2 — Questions and Answers
Question 1: On a sectional chart, NDB stations are depicted in what color?
- Blue
- Magenta (Correct answer)
- Brown
- Black
Correct answer: Magenta
NDB (Non-Directional Beacon) stations and their associated data boxes are shown in magenta on sectional charts, contrasting with VORs shown in blue.
Question 2: What frequency range do NDBs operate on as shown in NDB data boxes on sectional charts?
- 108–118 MHz
- 190–535 kHz (Correct answer)
- 962–1213 MHz
- 329–335 MHz
Correct answer: 190–535 kHz
NDBs operate in the low/medium frequency band between 190 and 535 kHz, listed in the magenta NDB data box on the sectional chart.
Question 3: On a sectional chart, what does the symbol for a localizer-only ILS component look like?
- A short bold line perpendicular to the runway centerline (Correct answer)
- A VOR compass rose at the runway threshold
- A dashed line extending from the runway
- A feathered arrow pointing to the runway
Correct answer: A short bold line perpendicular to the runway centerline
An ILS localizer is depicted on a sectional chart as a bold line (feather symbol) on the extended centerline of the runway it serves.
Question 4: What does 'HIWAS' printed in a NAVAID box on a sectional chart indicate?
- High-altitude weather advisory service broadcasts are available on that NAVAID
- Hazardous Inflight Weather Advisory Service broadcasts are available on that NAVAID (Correct answer)
- High wind alert station collocated
- Hazardous IFR weather area nearby
Correct answer: Hazardous Inflight Weather Advisory Service broadcasts are available on that NAVAID
HIWAS (Hazardous Inflight Weather Advisory Service) printed in a NAVAID box means the station broadcasts continuous weather advisories that pilots can receive by tuning the NAVAID frequency.
Question 5: On a sectional chart, an airway designated 'V-105' represents what type of route?
- A VFR corridor at 10,500 feet MSL
- A VHF Victor airway centered on VOR radials (Correct answer)
- A visual reporting route for military aircraft
- A volcanic hazard avoidance zone
Correct answer: A VHF Victor airway centered on VOR radials
Victor airways (V-routes) are low-altitude IFR airways from 1,200 feet AGL up to but not including 18,000 feet MSL, centered on VOR radials and labeled with 'V' followed by a number.
Question 6: What is the standard width of a Victor airway as depicted on a sectional chart?
- 4 nm total (2 nm each side of centerline)
- 8 nm total (4 nm each side of centerline) (Correct answer)
- 10 nm total (5 nm each side of centerline)
- 16 nm total (8 nm each side of centerline)
Correct answer: 8 nm total (4 nm each side of centerline)
Victor airways are 8 nautical miles wide — 4 nautical miles on each side of the centerline — as shown by the route lines on sectional charts.
