Quiz: 5 Questions To See How Well You Know These IFR Regulations

Do you know these IFR regulations?

1. 1) When fuel planning under IFR, you must have enough fuel in order to do what? (assuming you need an alternate)
   
   

   FAR 91.167 requires you to carry enough fuel onboard the aircraft in order to go to the first airport of intended landing, then to the alternate and thereafter for 45 minutes at normal cruising speed.

2. 2) You are planning a trip from St.Paul, MN (KSTP) to Fosston, MN (KFSE). The weather at KFSE requires an alternate according to FAR 91.169(b)(2)(i). You choose an alternate of Grand Forks, ND (KGFK). They have one ILS approach (except the glideslope is inoperative), a LOC BC approach and multiple RNAV approaches. What does the weather have to be in Grand Forks, and during what time to file it as an alternate?

   Since the glideslope is inoperative in Grand Forks, this means the only option is to use the nonprecision approach minimums. FAR 91.169(c)(1)(B) states that, for planning purposes, the airport that you choose to use for your alternate must have at least 800′ ceilings and a visibility of 2 SM at your ETA.

3. 3) Which approach lighting systems have red terminating or red side row bars?

   ALSF-1 has red terminating bars and ALSF-2 has red side row bars. So, if you shoot an approach to a runway that doesn’t have an ALSF-1 or ALSF-2 approach lighting system, you can’t descend below 100′ above TDZE without having another airport environment reference in sight.

4. 4) Which of these is not included as an acceptable reference for the airport environment according to FAR 91.175(c)?

   FAR 91.175(c) includes all acceptable references for the airport environment, and unfortunately, a taxiway adjacent to the runway is not one of them.

5. 5) In order to be instrument current according to FAR 61.57, you need to have done what in the preceding 6 months?

   In the 6 calendar months preceding the month of the flight, you would have needed to log at least 6 instrument approaches, conducted holding, as well as intercepting and tracking courses.
