The RNAV approach is a type of GPS-based procedure that is becoming ubiquitous in general aviation as the FAA continues to roll it out at thousands of airports around the United States. If you’re adept at flying an ILS approach, RNAV LPV procedures (offering “localizer performance with vertical guidance”) should be very familiar to you, since lateral and vertical deviations are identical at similar distances. Have a look at the chart below to learn about the nuances of these types of satnav-based approaches.
Chart Wise: RNAV Approaches
Key Takeaways:
- RNAV LPV (Localizer Performance with Vertical guidance) approaches are GPS-based procedures that are becoming widespread in general aviation and offer performance similar to ILS approaches.
- ATC uses specific phraseology for RNAV procedures, such as "straight in" clearances, to clarify when a hold in lieu of a procedure turn is not required.
- Pilots flying RNAV procedures may be cleared to an intermediate fix (instead of an initial approach fix) as long as it is on the final approach course and at least 3 miles from the final approach fix.
