FAA Instrument Flight Instructor (FII)IFR Procedures and ApproachesEasy

An instrument student is preparing for an RNAV (GPS) approach that indicates a 'T' symbol in the notes section of the approach plate. What does this symbol signify regarding published obstacle departure procedures (ODPs)?

  1. AA Terminal Area Chart (TAC) is required for this approach.
  2. BThere are non-standard takeoff minimums and/or climb gradients.
  3. CThe approach has a published minimum vectoring altitude (MVA) for ATC radar vectors.
  4. DThe approach is only authorized for aircraft equipped with RNAV (RNP) capabilities.
Show answer & explanation

Correct answer: B. There are non-standard takeoff minimums and/or climb gradients.

The 'T' symbol in the notes section of an instrument approach plate indicates that non-standard takeoff minimums and/or climb gradients apply to the airport. Pilots must consult the Takeoff Minimums and Obstacle Departure Procedures section of the NACO (National Aeronautical Charting Office) chart publication for specific information.

Why the other options are wrong

  • A. Terminal Area Charts (TACs) are for VFR operations in complex airspace, not specifically indicated by a 'T' on an instrument approach plate.
  • C. Minimum Vectoring Altitudes (MVAs) are for ATC use and not typically published on approach plates with a 'T' symbol.
  • D. RNP requirements are indicated differently, usually in the equipment requirements or minimums section.

T Symbol on Approach Plate

A 'T' symbol in the notes section of an instrument approach plate alerts pilots to the existence of non-standard takeoff minimums and/or climb gradients for obstacle departure procedures at that airport.

  • Indicates non-standard ODPs.
  • Requires consulting the Takeoff Minimums and Obstacle Departure Procedures section.
  • Crucial for ensuring obstacle clearance during departure.

Memory trick: The 'T' warns of Tricky Takeoffs.
