What is indicated by an Isogonic line on an aeronautical chart?
The amount and the direction of variation, which change slightly from time to time, are shown on most aeronautical charts as broken magenta lines called isogonic lines that connect points of equal magnetic variation. (The line connecting points at which there is no variation between TN and MN is the agonic line.)
How often are TAC charts updated?
Coverage of Terminal Area Charts are indicated by shaded boxes on the Sectional Chart index. These charts are updated every 56 days.
How do you identify variations using Isogonic lines?
Isogonic Lines The magnetic variation is shown in degrees, followed by the letter W or E as appropriate, at certain positions on the lines. The annual change is expressed in minutes with the letter W or E and is given in brackets immediately following the variation.
Is it legal to use an EFB?
IMPORTANT: This is the advisory circular that states it’s legal for FAA Part 91 GA piston aircraft pilots to use the iPad with current data as a paper chart replacement. EFBs can be used in all phases of flight in lieu of paper when: The EFB is the functional equivalent of the paper material.

What are helicopter route charts and Caribbean VFR charts?
Helicopter Route Charts are three-color charts that depict current aeronautical information useful to helicopter pilots navigating in areas with high concentrations of helicopter activity. Caribbean VFR Aeronautical Charts are designed for visual navigation to assist familiarization of foreign aeronautical and topographic information.
What is the Grand Canyon VFR aeronautical chart?
Grand Canyon VFR Aeronautical Chart covers the Grand Canyon National Park area and is designed to promote aviation safety and facilitate VFR navigation in this popular flight area.
What is a wall chart for VfR?
VFR Wall Planning Charts are designed for VFR preflight planning and provide aeronautical and topographic information of the continental U.S. The aeronautical information includes airports, radio aids to navigation, Class B airspace and special use airspace.
What is the difference between VFR charts and terminal area charts?
VFR Charts Sectional Aeronautical Charts are designed for visual navigation of slow to medium speed aircraft. Terminal Area Charts depict the airspace designated as Class B airspace. The information found on these charts, while similar to that found on Sectional Charts, is shown in much more detail because of the larger scale.
