IFR Cross-Country Planning

Alternate Minima Operational Consideration – RNP Approach

– Must use weather minima for nonprecision approach procedures during the flight planning.
– LPV, LNAV/VNAV, or LP may be used upon arrival if SBAS is available.

In situations where RAIM is predicted to be unavailable, the flight must:

• Rely on other approved navigation equipment
• Re-route to where RAIM is available
• Delay departure, or
• Cancel the flight

The pilot in command of each aircraft operated under IFR in controlled airspace must
ensure that a continuous watch is maintained on the appropriate frequency and must
report the following as soon as possible

– The time and altitude of passing each designated reporting point, or the reporting points specified by ATC, except that while the aircraft is under radar control, only the passing of those reporting points specifically requested by ATC need be reported;
– Any unforecast weather conditions encountered; and
– Any other information relating to the safety of flight.

GPS Navigation Equipment Approved for IFR Operations

– TSO-C145()
– TSO-C146()

Preferred Route

A system of preferred routes has been established to guide pilots in planning their route of
flight, to minimize route changes during the operational phase of flight, and to aid in the
efficient, orderly management of the air traffic using the federal airways.
– Located in the Chart Supplement U.S.

Establishment of Preferred IFR Routes Program

1. The objective of Preferred IFR Routes is the expeditious movement of traffic during heavy demand periods and the reduction of TMIs and coordination.

2. Preferred IFR Routes must only be established when traffic density and/or safety make such routes necessary for the expeditious movement of air traffic.
