IFR Flashcards
Standard Alternate minima
2+ precision: 400-1 or 200-1/2
1 precision: 600-2 or 300-1
Non-precision only: 800-2 or 300-1
No ifr approach: 500 above minimum IFR altitude that would allow a vfr approach and landing
Alternate mins sliding scale
If 600-2 then 700-1 1/2 or 800-1
If 800-2 then 900-1 1/2 or 1000-1
IFR propeller driven fuel mins
Fly to dest approach and missed, fly to and land at alternate, plus 45 minutes. If no alternate fly to destination, approach and missed, then fly 45 minutes.
IFR turbojet fuel requirements
Fly to dest approach and missed, fly to and land at alternate, plus 30 minutes. If no alternate fly to destination, approach and missed, then fly 30 minutes.
GFA alternate
No cloud lower than 1,000’ above lowest HAT/HAA
No CB
Vis not less than 3Sm
What is HAT and HAA
Height Above Tdze
Height Above Aerodrome
Spec vis per aircraft category
A-1
B-1 1/2
C/D-2
Standard IFR departure
Cross departure end of runway at least 35 ft
Climb straight ahead till 400’ AAE
Maintain at least 200’ per nm
Visual approach
500’ above minimum IFR altitude, ground vis 3Sm,
Contact approach minimum
1 nm flight vis, 1,000’ above highest obstacle within 5 nm until required visual reference, complete approach clear of cloud.
Minimum distance for alternate if both planned approaches are gnss
100nm
75 where both aerodromes are in Nunavut, or north of 56N in Quebec or Labrador
