IFR Enroute Regulations Flashcards
Recent flight experience
•General Experience
•Passenger Currency
•Night Takeoffs and Landings
•Instrument Experience
•Except as provided in paragraph (e) of this section, a person may act as pilot in command under IFR or weather conditions less than the minimums prescribed for VFR only if:
•Within the 6 calendar months preceding the month of the flight, that person performed and logged at least the following tasks and iterations in an airplane, powered-lift, helicopter, or airship, as appropriate, for the instrument rating privileges to be maintained in actual weather conditions.
Instrument proficiency check (IPC)
•Except as provided in paragraph (e) of this section, a person who has failed to meet the instrument experience requirements of paragraph (c) of this section for more than six calendar months may reestablish instrument currency only by completing an instrument proficiency check. The instrument proficiency check must consist of at least the following areas of operation:
•Air traffic control clearances and procedures;
•Flight by reference to instruments;
•Navigation systems;
•Instrument approach procedures;
•Emergency operations; and
•Postflight procedures
IPC requirements
•In an aircraft that is appropriate to the aircraft category;
•For other than a glider, in a full flight simulator or flight training device that is representative of the aircraft category; or
•For a glider, in a single-engine airplane or a glider.
Who can give an IPC
•An examiner;
•A person authorized by the U.S. Armed Forces to conduct instrument flight tests, provided the person being tested is a member of the U.S. Armed Forces;
•A company check pilot who is authorized to conduct instrument flight tests under part 121, 125, or 135 of this chapter or subpart K of part 91 of this chapter, and provided that both the check pilot and the pilot being tested are employees of that operator or fractional ownership program manager, as applicable;
•An authorized instructor; or
•A person approved by the Administrator to conduct instrument practical tests.
You may descend below the MDA or DH only if
•The aircraft is continuously in a position allowing for normal rate of descent to a landing on the intended runway;
•The flight visibility is at or above the visibility required to complete the approach; and
•At least one of the following visual references for the intended runway is distinctly visible and identifiable to the pilot
Civil airport takeoff minimums
•This paragraph applies to persons operating an aircraft under part 121, 125, 129, or 135 of this chapter.
•Unless otherwise authorized by the FAA, no pilot may takeoff from a civil airport under IFR unless the weather conditions at time of takeoff are at or above the weather minimums for IFR takeoff prescribed for that airport under part 97 of this chapter.
•If takeoff weather minimums are not prescribed under part 97 of this chapter for a particular airport, the following weather minimums apply to takeoffs under IFR:
•For aircraft, other than helicopters, having two engines or less - 1 statute mile visibility.
•For aircraft having more than two engines - 1/2 statute mile visibility.
Limitations of procedure turns
In the case of a radar vector to a final approach course or fix, a timed approach from a holding fix, or an approach for which the procedure specifies “No PT,” no pilot may make a procedure turn unless cleared to do so by ATC.
IFR cruising altitude
•When operating below 18,000 feet MSL and:
•On a magnetic course of zero degrees through 179 degrees:
•Any odd thousand-foot MSL altitude (such as 3,000, 5,000, or 7,000); or
•On a magnetic course of 180 degrees through 359 degrees:
•Any even thousand-foot MSL altitude (such as 2,000, 4,000, or 6,000).
Fuel requirements
•Except as provided in paragraph (b) of this section, no person may operate an aircraft in IFR conditions unless it carries enough fuel (considering weather reports or forecasts or any combination of them) to:
•Complete the flight to the first airport of intended landing;
•Fly from that airport to the alternate airport; and
•Fly after that for 45 minutes at normal cruising speed or, for helicopters, fly after that for 30 minutes at normal cruising speed.
When is an alternate required
An Alternate airport required IF the following is broken:
•For at least 1 hour before and for 1 hour after the estimated time of arrival, the ceiling will be at least 2,000 feet above the airport elevation and the visibility will be at least 3 statute miles.
IFR alternate requirements
An airport cannot be an alternate unless at the ETA, the ceiling/visibility are at/above:
•Minima specified for the selected approach procedure
•Standard minima for the selected approach
•For a Precision Approach: 600’ and 2 SM
•For a Non-Precision Approach: 800’ and 2 SM
•No Approach: The ceiling/visibility must allow descent from MEA, Aproach, LDG under VFR
WAAS and alternates
•If using a non-WAAS GPS (TSO C129/196)
•Destination AND alternate airports can not solely have GPS approaches
•AIM 1-1-17
•If using a WAAS GPS (TSO C145/146)
•When choosing your alternate airport, must use LNAV minimums
•LPV minimums can not be used
