What are instrument departure procedures? - ANS-Preplanned IFR departures
providing obstacle clearance from terminal area to appropriate enroute structure
Terminal area - ANS-A designated area of controlled airspace surrounding a major
airport with high volume of traffic
What are the required inspections for the aircraft for an IFR flight? - ANS-AAVIATE
Annual
Airworthiness Directives
VOR (30 days) (date, signature, location, deviance)
100hr
Altimeter/Pitot/Static (24 cal mo)
Transponder (24 mo)
ELT (12 mo - 1hr use, 50% of life)
What does the pilot in command need to know before conducting an IFR flight? -
ANS-NWKRAFT
NOTAMS
Weather reports and forecasts
Known ATC traffic delays
Runway lengths of intended use
, Alternatives available
Fuel requirements
Takeoff and landing performance data
When is an alternate airport required? - ANS-1 hour prior or after ETA - less than 2000 ft
ceiling / 3 miles visibility
What is the requirement for filing an alternate airport? - ANS-Weather reporting system
Instrument approach (or weather allows for descent from MEA to landing in VFR
conditions) and weather minimums (800-2 non-precision, 600-2 precision)
Diverse Departure - ANS-Airport/runway without published ODP
