What does ‘NW KRAFT’ stand for in preflight info required for IFR?
N - NOTAMs.
W - Weather reports and forecasts.
K - Known traffic delays as advised by ATC.
R - Runway length of intended use.
A - Alternatives available if flight cannot be completed as planned.
F - Fuel requirements.
T - Takeoff and landing performance data.
What is the requirement for operating an aircraft in controlled airspace under IFR?
No person may operate an aircraft in controlled airspace under IFR unless that person has filed an IFR flight plan and received an appropriate ATC clearance.
What is the ruling regarding taking off into IMC in uncontrolled airspace?
Taking off into IMC in uncontrolled airspace without a clearance or a release has been ruled by the NTSB as a violation of §91.13, careless or reckless operation.
How can an IFR flight plan be filed?
- FSS: by phone (1-800-WX-BRIEF), over the radio (GCO/RCO), in person.
- Online: www.1800wxbrief.com (Leido), www.fltplan.com (Garmin).
- EFB (e.g., Foreflight).
- With ATC (over radio or phone if no other means available).
What are pop-up IFR clearances?
Pop-up IFR clearances let pilots transition from VFR to IFR, even without a previously filed flight plan, under ATC authorization.
When should an IFR flight plan be filed?
File at least 30 minutes prior to estimated departure. Non-scheduled flights above FL230 should be filed at least 4 hours before estimated departure time.
How is a flight plan canceled at towered airports?
Automatically canceled by ATC upon landing.
How is a flight plan canceled at non-towered airports?
Pilot must contact ATC / FSS to cancel by radio or phone.
What are Preferred IFR Routes?
Preferred IFR Routes are published in the Chart Supplement U.S. The AIM recommends filing a preferred route if one is available.
What are the GPS considerations for filing an alternate?
Equipped with a non-WAAS GPS? Flight plan can be based on GPS approach availability at either the destination or the alternate, but not at both.
What are the IFR cruising altitudes below FL290 based on magnetic course?
0º-179º: ODD thousands (below 18,000’) or Flight Levels (at or above FL180).
180º-359º: EVEN thousands (below 18,000’) or Flight Levels (at or above FL180).
What are the IFR minimum fuel requirements?
45 minutes calculated at normal cruise, fuel from destination to most distant alternate (if alternate required), fuel from departure to destination airport.
When is a destination alternate required?
A destination alternate is always required unless an instrument approach is published and available for the destination, and for at least 1 hour before to 1 hour after ETA, ceiling will be at least 2000’ above airport elevation and visibility will be at least 3 SM.
What are the minimum weather conditions required at an airport to list it as an alternate for a precision approach?
600 ft ceiling and 2 SM visibility.
What are the minimum weather conditions required at an airport to list it as an alternate for a non-precision approach?
800 ft ceiling and 2 SM visibility.
