According to 91.167, how much fuel is needed for an IFR flight?

Need enough to first airport, that airport to alternate, and 45 minutes cruising past alternate.

According to 91.169, when do you need an alternate on your flight plan?

For one hour before and one hour after the eta, the weather conditions are below: the ceiling will be at least 2000ft above the airport elevation, and the visibility is at least 3SM

According to 91.169 what are the minimums for alternates?

Precision: 600ft ceiling and 2sm

Non-precision: 800ft ceiling and 2sm

NO Approach: Must be able to descend below the MEA, approach, and land under basic VFR

According to 91.171 how often do VOR checks need to be done?

VOR must be operationally checked within 30 days and was found to be within limits to be used for navigation.

What does 91.173 say?

Can’t operate under IFR unless an IFR flight plan has been filed and appropriate clearance has been received.

What is DA/MDA according to 91.175?

The highest of the following: 1. The DA/MDA prescribed for the approach procedure. 2. DA/MDA prescribed for the pilot in command. 3. DA/MDA appropriate for the aircraft equipment available and used during the approach.

According to 91.175 what 3 things do you need to descend below the DA/MDA?

1. In a position to descend to a landing on the intended runway can be made at a normal rate of descent under normal maneuvers.

2. The flight visibility is not less than what is prescribed for the approach.

3. The approach lights system but cannot go below 100ft above TZDE unless the red terminating or side row bars are visible.

According to 91.175 what else do you need see to be able to land from an approach?

Threshold, Threshold marking, threshold lights

Runway end identifier lights

Visual glideslope indicator

TDZ, TDZ markings, TDZ lights

Runway, runway markings, runway lights

What are the minimum altitudes for IFR according to 91.177?

Cant operate below MEA and a MOCA for a particular route segment, can go below MEA down to but not below MOCA. For VOR nav this is within 22nm of VOR. Climbs to higher minimums should begin immediately after passing beyond which the min. applies. The point beyond which that higher min. alt. applies shall be crossed at or above the applicable MCA.

What are the IFR cruising altitude rules according to 91.179?

In controlled airspace, altitude is whatever is assigned by ATC. In uncontrolled when below 18000msl on a mag course of 0-179 any odd thousand-foot msl altitude. On mag course 180-359 any even thousand foot.

What does 91.181 say about course to be flown?

Must fly on ATS route along the centerline of the runway. On any other route along the direct course, but does not prohibit maneuvering to pass clear of air traffic or maneuvering to VFR conditions.

What communications are required under 91.183?

Must report the time and altitude passing each designated reporting point, or the points specified by ATC, except while under radar control only the ATC requested ones must be reported. Any unforcast weather conditions, any other information relating to the safety of flight.

According to 91.185 what do you do if you lose comms in VFR?

In VFR conditions continue under VFR and land as soon as practicable.

According to 91.185 what do you do if you lose comms in IFR?

In IFR conditions 1) route by assigned in last clearance, if being vectored go direct to fix, route, or other specified route, in absence of assigned route by roue filed. 2) altitude at the highest of the following, alttidue assigned by atc, the min. altitude for IFR ops, altitude ATC has advised may be expected in further clearance. 3) Leave clearance limit is a fix from which an approach begins. If the clearance limit fix is not a fix for the beginning of an approach leave the limit at EFC time and proceed to fix that begins an approach.

According to 91.187 what do you need to report in controlled airspace regarding malfunctions?

If in controlled airspace PIC shall report as soon as practical to ATC of any malfunctions of navigation, approach, or communication equipment. In the report it should include aircraft identification, equipment affected, degree to which the capability of the pilot to operate under IFR, nature and extent of assistance desired from ATC.

What is GRABCARD?
