FAA Private Pilot Airplane (PAR)Navigation and Flight PlanningMedium
A pilot is flying VFR at 3,500 feet MSL. The sectional chart shows a VORTAC with a frequency of 114.3, a three-letter identifier 'ABC', and a small 'T' in the upper right corner of the VORTAC box. What does the 'T' indicate?
- AThe VORTAC is temporarily out of service for maintenance.
- BThe VORTAC operates on a test frequency and should not be used for primary navigation.
- CThe VORTAC is a Terminal VOR, primarily for low-altitude and terminal area navigation.
- DThe VORTAC has a voice communication capability on that frequency.
Show answer & explanationAnswer & explanation
Correct answer: C. The VORTAC is a Terminal VOR, primarily for low-altitude and terminal area navigation.
A small 'T' in the upper right corner of a VOR/VORTAC box on a sectional chart indicates that it is a Terminal VOR, meaning it is optimized for use within a specific terminal area and typically has a shorter range and lower altitude service volume compared to high- or low-altitude VORs.
Why the other options are wrong
- A. Out-of-service facilities are typically noted by NOTAMs or crossed-out symbols, not a 'T'.
- B. The 'T' does not relate to test frequencies; VORs operate on standard frequencies.
- D. Voice capability is usually indicated by a small square with an 'R' (for 'RCO') or other specific symbols, not a 'T'.
Terminal VOR (VOR-T)
A Terminal VOR is a VOR station with a limited service volume, designed for navigation within a terminal area, typically up to 12,000 feet AGL and a 25 NM radius.
- Indicated by a 'T' symbol on sectional charts.
- Lower power output than high or low altitude VORs.
- Used for approach and departure procedures.
Memory trick: Terminal VORs are like local guides, only for short trips in the area.
