FAA Airline Transport Pilot (ATM)Navigation, Air Traffic Control and ProceduresEasy
A pilot is planning an IFR flight at FL270 within the continental United States. Which publication would provide the most appropriate and detailed information regarding en route navigation, communication frequencies, and air traffic control procedures?
- AVFR Sectional Chart
- BEn Route High Altitude Chart
- CAeronautical Information Manual (AIM)
- DTerminal Procedures Publication (TPP)
Show answer & explanationAnswer & explanation
Correct answer: B. En Route High Altitude Chart
En Route High Altitude Charts are specifically designed for IFR navigation at FL180 and above, providing essential information like airways, navigational aids, communication frequencies, and other ATC-related data.
Why the other options are wrong
- A. VFR Sectional Charts are for visual flight rules and low-altitude navigation, not IFR at FL270.
- C. The AIM provides general aviation information and regulations, not specific charting for en route navigation.
- D. TPP contains instrument approach procedures, SIDs, and STARs, not primary en route information.
En Route High Altitude Chart
A chart specifically designed for IFR navigation at altitudes from 18,000 feet MSL (FL180) up to FL450, showing airways, navigational aids, and communication frequencies.
- Used for IFR navigation at FL180 and above.
- Displays Jet Routes, VORs, air traffic control information.
- Updated periodically to reflect changes in airspace and navigation.
Memory trick: Charts guide your flight, knowing which to pick is light.
