IFR Flight

Question 1

What is IFR flight?

Answer 1

Flight conducted under Instrument Flight Rules, where pilots operate primarily by reference to instruments, often in IMC or reduced visibility.

Question 2

What are the basic requirements for IFR flight?

Answer 2

IFR-certified aircraft, IFR-rated pilot, IFR flight plan, appropriate ATC clearance, and operational instruments and equipment.

Question 3

What are the minimum equipment requirements for IFR flight?

Answer 3

Pitot-static system, gyroscopic instruments (attitude indicator, heading indicator, turn coordinator), navigation equipment, communication radios, and lighting as per 91.205.

Question 4

How do pilots file an IFR flight plan?

Answer 4

File with ATC via radio, phone, or online system including aircraft ID, route, altitude, estimated time, fuel, and alternate airport if required.

Question 5

What is ATC clearance in IFR flight?

Answer 5

Authorization from ATC for a specific route, altitude, and clearance limit; pilots must comply with all instructions unless amended.

Question 6

How is altitude selected for IFR flight?

Answer 6

Based on direction of flight (odd thousands eastbound, even thousands westbound in US), terrain, obstacle clearance, and airspace requirements.

Question 7

What is the purpose of IFR separation?

Answer 7

Ensures safe spacing between aircraft in IMC or controlled airspace using ATC radar, procedural separation, and altitude assignments.

Question 8

How is position determined during IFR flight?

Answer 8

By navigation systems: VOR, NDB, DME, GPS, RNAV, or radar vectors from ATC.

Question 9

How are holding patterns used in IFR flight?

Answer 9

To delay aircraft, maintain safe separation, or await clearance; pilots follow published pattern, timing, and speed limits.

Question 10

What is the procedure for an instrument approach under IFR?

Answer 10

Intercept final approach course, descend on published altitudes, maintain alignment with lateral and vertical guidance, and execute landing or missed approach if required.

Question 11

What is a precision approach?

Answer 11

Provides both lateral and vertical guidance, such as ILS or LPV approaches.

Question 12

What is a non-precision approach?

Answer 12

Provides lateral guidance only (VOR, NDB, localizer-only approaches) with step-down altitudes.

Question 13

How is a missed approach executed?

Answer 13

Apply climb power, pitch to climb attitude, retract flaps as required, follow published missed approach procedure, and communicate with ATC.

Question 14

What is the importance of IFR fuel planning?

Answer 14

Ensure sufficient fuel for planned route, alternate airport, and reserves as required by regulations.

Question 15

How are alternate airports chosen in IFR flight?

Answer 15

Must be forecasted to have weather above minimums at ETA plus 1 hour, accessible by available navigation aids, and compatible with aircraft performance.

Question 16

What is the role of ATC during IFR flight?

Answer 16

Provide separation, clearances, traffic advisories, radar vectors, and assistance during emergencies or deviations.

Question 17

How are IFR departures conducted?

Answer 17

Follow ATC clearance, published departure procedures (SIDs), comply with climb gradients, and maintain assigned headings and altitudes.

Question 18

What is the importance of instrument cross-check?

Answer 18

Ensures accurate control, situational awareness, and detection of instrument or navigation errors during IFR flight.

Question 19

How is aircraft control maintained in turbulence during IFR flight?

Answer 19

Use attitude instrument as primary reference, apply smooth control inputs, maintain airspeed within safe limits, and anticipate altitude deviations.

Question 20

How is ATC communication maintained in IFR flight?

Answer 20

Monitor assigned frequency, read back clearances, report position as required, and request amendments if necessary.

Question 21

What is the importance of approach briefings in IFR flight?

Answer 21

Familiarizes the pilot with approach type, frequencies, altitudes, missed approach procedures, and potential hazards.

Question 22

How is a transition from en route to approach phase managed?

Answer 22

Descend per ATC clearance or approach chart, intercept final approach course, configure aircraft, and monitor instruments for precision or non-precision guidance.

Question 23

What is the difference between radar vector and pilot navigation approach?

Answer 23

Radar vector: ATC provides headings and altitudes. Pilot navigation: Pilot navigates using published procedures, navaids, or GPS.

Question 24

What are common IFR flight hazards?

Answer 24

Spatial disorientation, low visibility, instrument failure, weather changes, ATC misunderstanding, and turbulence.

Question 25

How is spatial disorientation avoided during IFR flight?

Answer 25

Trust primary flight instruments, cross-check instruments, avoid abrupt control inputs, and use autopilot if necessary.

Question 26

How are instrument failures handled in IFR flight?

Answer 26

Use backup instruments, cross-check navigation systems, declare emergency if needed, and follow alternate procedures.

Question 27

How is situational awareness maintained during IFR flight?

Answer 27

Monitor position, airspeed, altitude, navigation, traffic, and weather; maintain communication with ATC; anticipate changes.

Question 28

What is the procedure for ATC clearance amendments?

Answer 28

Read back revised instructions, comply promptly, and confirm new routing or altitude.

Question 29

How are minimum safe altitudes determined in IFR flight?

Answer 29

Based on terrain, obstacles, and airspace charts; maintain altitude at least 1,000 ft above obstacles in non-mountainous areas and 2,000 ft in mountainous areas.

Question 30

How is approach spacing managed by ATC?

Answer 30

Through radar separation, speed control, and sequencing to ensure safe intervals between IFR aircraft on final approach.

Question 31

How is aircraft control prioritized in IFR flight?

Answer 31

Aviate first (control aircraft), navigate second (follow route), communicate last (ATC, passengers).

Question 32

How are IFR departures adjusted for obstacle clearance?

Answer 32

Follow published climb gradients, adhere to SID instructions, and maintain assigned headings until clear of obstacles.

Question 33

How is IFR arrival planning conducted?

Answer 33

Identify approach type, verify navaids, check weather and alternate airports, review approach procedures, and brief missed approach.

Question 34

How is pilot workload managed during IFR flight?

Answer 34

Use autopilot, checklist discipline, instrument scan, proper ATC communication, and task prioritization.

Question 35

What are IFR approach minima?

Answer 35

Lowest altitude and visibility limits at which an approach may be continued for landing under IFR.

Question 36

How are ATC advisories used in IFR flight?

Answer 36

Provide traffic alerts, course guidance, weather information, and clearance amendments as needed.

Question 37

How is IFR flight conducted in IMC?

Answer 37

Maintain control solely by instruments, adhere to ATC instructions, follow published procedures, and manage workload and situational awareness.

Question 38

How are departures, en route, and approaches integrated in IFR flight?

Answer 38

Use clearance, published procedures, instrument cross-check, and ATC guidance to transition safely through each phase.
