FAA Private Pilot Airplane (PAR)Navigation and Flight PlanningEasy
A pilot is flying VFR at 3,500 feet MSL. The sectional chart shows a VOR frequency of 115.3 MHz with a small 'T' suffix. What does the 'T' indicate regarding this VOR?
- AThe VOR is undergoing maintenance and may be unreliable.
- BThe VOR is a Terminal VOR, primarily for low-altitude, terminal area navigation.
- CThe VOR has limited operational hours and is not available 24/7.
- DThe VOR transmits weather information (TIROS) on its frequency.
Show answer & explanationAnswer & explanation
Correct answer: B. The VOR is a Terminal VOR, primarily for low-altitude, terminal area navigation.
The 'T' suffix next to a VOR frequency on a sectional chart designates it as a Terminal VOR. These VORs are specifically designed for use in terminal areas and have a restricted service volume.
Why the other options are wrong
- A. A 'T' does not indicate maintenance; other chart symbols or NOTAMs would indicate this.
- C. The 'T' suffix does not indicate limited operational hours; that information would typically be in the A/FD or NOTAMs.
- D. VORs do not transmit TIROS weather; ATIS or HIWAS are used for weather information.
Terminal VOR (VOR-T)
A type of VOR station specifically designed for use in the terminal area around airports, characterized by a limited service volume.
- Identified by a 'T' suffix next to its frequency on sectional charts.
- Service volume extends from 1,000 feet AGL up to 12,000 feet AGL, with a radius of 25 NM.
- Used primarily for approach and departure procedures.
Memory trick: Navigating with VORs, remember their 'Service' to 'Terminal', 'Low', and 'High' flyers.
