What are the three fundamental skills of instrument flight?

A
  • Instrument Cross Check
  • Instrument Interpretation
  • Aircraft Control
103
Q

What are NOTAMS and what are the three types?

A

Notices to Air Missions- they contain critical information that may affect your decision of flight.

NOTAM D- NAV facilities out of service.
NOTAM L- Taxi closures, inoperative VASI, etc.

28 Days

107
Q

When must you receive clearance from ATC at an airport?

A

Takeoff, Landing, Crossing Runways

108
Q

What are the three components of an ILS?

A
  • Localizer
  • Beacon
  • Glideslope
109
Q

What would you do if you lost a circuit breaker?

A
  • Ask if it is needed in the flight.

- If so, I would not want to risk an electrical fire and would leave it be.

110
Q

Do you need to have a Mode C transponder on an IFR flight plan in class E and G?

A

Yes.

111
Q

If you do need an alternate airport on an IFR flight plan, what weather minimums must exist to consider it an alternate?

A

If it has a:

Precision Approach
- 600ft ceiling; 2SM Visibility

Non-Precision Approach
- 800ft ceiling; 2SM Visibility

No Instrument Approach
- Ceiling and visibility must allow decent from MEA and allows for a basic VFR approach.

112
Q

What are AIRMETs?

A

Advisories for:

Tango- Turbulence

Sierra- IFR

Zulu- Icing

113
Q

Can you operate an instrument flight without RAIM or WAAS?

A

Yes, if you can back up the GPS with VHF frequencies.

114
Q

What does the visual decent point mean?

A

The point at which you may descend to the runway IF you have it in sight.

115
Q

What is a side-step maneuver?

A

Used for parallel runways with only one approach.

116
Q

You are on an IFR cross country and realize you are lower on fuel than you had planned. Should you report this to ATC even if you believe you can make it to the airport, but only if there are no unforeseen delays?

A

Yes. You should declare “minimum fuel”.

117
Q

When can you descend to the next instrument approach segment?

A

When cleared for the approach and established on a segment for the approach.

118
Q

Can and IFR recency (first 6 months) be completed in a simulator?

A

Yes, as long as it is the same category aircraft and is in simulated instrument conditions.
- A flight instructor is not needed.

For training toward the rating

  • An authorized instructor is present to verify.
  • Logs the time, content, and training device.
119
Q

Can you continue an ILS or precision approach if you lose vertical guidance?

A

Yes, but only if you started your time at the final approach fix.

120
Q

What special preflight checks would you perform for instrument flight versus VFR flight?

A
  • Pitot Heat
  • Magnetic Compass
  • Master Switch
  • Attitude Indicator Stable in 5 minutes or less
  • VOR
  • Check Turn Coordinator while Taxiing
121
Q

What are the large and small numbers within a specific latitude/longitude grid on the IFR sectional?

A

The OROCA numbers. They tell you the minimum altitude you can fly within that grid.

122
Q

How large is the protected area of a VOR? The non-protected area?

A

Protected- 4 miles

Non-Protected- 1 mile

123
Q

What is the required equipment for flying for hire and beyond power off gliding distance from the shore?

A

Approved flotation device and at least one pyrotechnic signaling device.

124
Q

Looking at an IFR sectional, what is the quickest way to tell it and airport has an instrument approach?

A

Blue and green airports have approaches. Brown airports do not.

125
Q

What does “CRAFT” stand for?

A 
Clearance Limit
Route
Altitude
Frequency
Transponder
126
Q

List some enroute weather information sources.

A

HIWAS- Hazardous inflight weather advisory service; hazardous and urgent weather.

Automated Terminal Information Service (ATIS)

Automated Surface Observation System (ASOS)

Automated Weather Observation System (AWOS)

ARTCC- Advises anticipated adverse weather conditions and SIGMETs.

127
Q

What does EFC mean? You determine you will reach the holding fix in 4 minutes. ATC has not given you an EFC. What should you do?

A

EFC- Expect Further Clearance

Query ATC.

128
Q

What is a standard terminal arrival? (STAR)

A
  • Serves as a transition from enroute structure to a point from which an approach can begin.
  • Puts you in the general vicinity of the airport.
129
Q

Instrument PIC recency of experience for 6 months? More than 6 months? More than 12 months?

A

Within 6 months in actual or simulated IFR in the same category aircraft, log:

  • 6 Instrument Approaches
  • Holding Procedures and Tasks
  • Intercept and Track Courses through Navigation System

More than 6 Months:
- Log flights with a safety pilot or instructor.

More than 12 Months:
- Requires instrument proficiency check.

130
Q

May we fly into an area where icing is forecasted?

A

Absolutely not. It is illegal.

131
Q

What are the required aircraft maintenance inspections for IFR?

A 
Annual (12 Calendar Months)
VOR (30 Days)
I (100 Hour)
Altimeter/Pitot Static System (24 Calendar Months)
Transponder (24 Calendar Months)
ELT (12 Calendar Months)
132
Q

How does the automatic direction finder differ from a VOR?

A

Does not show radicals. Just shows position relative to the ADF.

133
Q

Does a VFR on Top clearance mean the IFR flight plan is cancelled?

A

No. It does not.

134
Q

What are the ways a VOR may be certified for use on an instrument flight? What information must be recorded? Does the information have to be in an aircraft logbook?

A
  • VOT, Ground, or Airborne Check
  • Name, Date, Place, and Error
  • No. It just has to be written down.
135
Q

What is the difference between an isobar and an isotherm?

A

Isobar- Connects lines of equal pressure.

Isotherm- Connects lines of equal temperature.
