a. To maintain IFR proficiency, pilots are urged to practice IFR procedures whenever possible, even when operating VFR. Some suggested practices include:
1. Obtain a complete preflight briefing and check NOTAMs. Prior to every flight, pilots should gather all information vital to the nature of the flight. Pilots can receive a regulatory compliant briefing without contacting Flight Service. Pilots are encouraged to use automated resources and review AC 91-92, Pilot's Guide to a Preflight Briefing, for more information. NOTAMs are available online from the Federal NOTAM System (FNS) NOTAM search website (https://notams.aim.faa.gov/notamSearch/), private vendors, or on request from Flight Service.
2. File a flight plan. This is an excellent low-cost insurance policy. The cost is the time it takes to fill it out. The insurance includes the knowledge that someone will be looking for you if you become overdue at your destination. Pilots can file flight plans either by using a website or by calling Flight Service. Flight planning applications are also available to file, activate, and close VFR flight plans.
3. Use current charts.
4. To enhance situational awareness and minimize distractions during critical phases of flight, pre-load all intended waypoints into a suitable RNAV system while the aircraft is on the ground.
5. Use the navigation aids. Practice maintaining a good course; keep the course deviation indicator centered.
6. Maintain a constant altitude that is appropriate for the direction of flight.
7. Estimate en route position times.
8. Make accurate and frequent position reports to the FSSs along your route of flight.
b. Simulated IFR flight is recommended (under the hood); however, pilots are cautioned to review and adhere to the requirements specified in 14 CFR section 91.109 before and during such flight.
c. When flying VFR at night, in addition to the altitude appropriate for the direction of flight, pilots should maintain an altitude which is at or above the minimum en route altitude as shown on charts. This is especially true in mountainous terrain, where there is usually very little ground reference. Do not depend on your eyes alone to avoid rising unlighted terrain, or even lighted obstructions such as TV towers.
