What is required to be familiar with before executing a flight under IFR?

Being familiar with all available information concerning the flight is essential before executing a flight under Instrument Flight Rules (IFR) for several reasons. IFR flights operate in more complex environments compared to Visual Flight Rules (VFR) because pilots are generally flying in conditions where visibility may be limited. This necessitates comprehensive knowledge of various aspects of the flight.

Understanding weather conditions is crucial, not only for the destination airport but also for any alternate airports, departure airfields, and en route weather. Additionally, knowledge about the flight route, including waypoints, airspace restrictions, and air traffic control (ATC) instructions is vital for safe navigation.

Moreover, being aware of any relevant NOTAMs (Notices to Airmen) and the operational status of navigational aids along the route adds another layer of safety and preparedness. This breadth of information equips pilots with the necessary tools to make informed decisions, ensuring both compliance with regulations and enhancement of safety during the flight.

While familiarity with air traffic patterns, weather at destination, and standard operating procedures are important, they are components of the broader requirement of having an overall understanding of all factors that may impact the flight.
