Navigation GK

Question 1

Aircrew Flight Restrictions (2.4.2)

11-202v3

Answer 1

• Crew Rest IAW (3.1)
• 12 hours bottle to throttle to include after effects
• 72 hrs from donating blood, plasma, or bone marrow
• 24 hr from SCUBA diving, surface supplied diving, 10 A/C px checks 10 mins or more below sea level, and/or compression chamber exposure

Question 2

Crew Rest (3.1)

11-202v3

Answer 2

• Crew rest is compulsory for aircrew members prior to performing any duties involving aircraft operations and is a minimum of 12 non-duty hours before the flight duty period (FDP) begins.
• 3.1.1. Aircrew members must inform the PIC or mission execution authority if not sufficiently rested for flight duties. (T-3) 3.1.2.
• If crew rest is interrupted, individuals will immediately inform the PIC or mission execution authority and will either begin a new crew rest period or not perform flight duties. (T-1) An interruption is any official business conducted after crew rest. Exception: PIC (or designee) may initiate mission-related communication with official agencies without interrupting crew rest.
• 3.1.2. (AETC) “Official business” includes any digital communication (e.g., cellular phone, text message, communication application, scheduling application) used to contact aircrew members. Aircrew members will consider crew rest interrupted due to any official digital notification or alert (e.g., mandatory recall, schedule change, etc.) (T-3). Exception: Aircrew members may voluntarily check official digital communications.
• 3.1.3. The authority waiving the 12-hour crew rest period must ensure that the PIC is notified prior to beginning crew rest. (T-2) The PIC is not required to accept reduced crew rest, even if waiver has been granted by the appropriate waiver authority.
• When three or more consecutive flight duty periods of at least 12 hours duration are scheduled, crew rest may be reduced by the PIC to a minimum of 10 hours in order to maintain a 24-hour work/rest schedule. The 10-hour crew rest authorization is only used to keep crews in 24-hour clock cycles, not for scheduling convenience or additional sortie generation.

Question 3

Flight Duty Period (3.2)

11-202v3

Answer 3

• The FDP begins when an aircrew member first reports for official duty and ends at final engine shutdown after the final flight of the completed mission.
• The PIC is authorized to extend FDP a maximum of 2 hours to compensate for unplanned mission delays.
• 3.2.3. If official post-flight duties are anticipated to exceed 2 hours, consider reducing the FDP to ensure safe completion of those duties.

Question 4

IMC vs IFR, VMC vs VFR (4.1)

11-202v3

Answer 4

• 4.1.1. Instrument flight rules (IFR) are a set of rules governing the conduct of instrument flight. [NAS Only] This is a term used by pilots and controllers to indicate type of flight plan. The term “IFR” is also used in the United States to indicate weather conditions that are less than minimum
  VFR requirements.
• 4.1.2. Instrument meteorological conditions (IMC) are weather conditions expressed in terms of visibility, distance from clouds, and ceilings less than the minima specified for visual meteorological conditions.
• 4.1.3. Visual flight rules (VFR) govern the procedures for conducting flight under visual conditions. [NAS Only] The term “VFR” is also used in the United States to indicate weather conditions that are equal to or greater than minimum VFR requirements. In addition, it is used by pilots and controllers to indicate type of flight plan.
• 4.1.4. Visual meteorological conditions (VMC) are weather conditions expressed in terms of visibility, distance from clouds, and ceilings equal to or better than specified minima.

Question 5

(4.10.1.) Aircrew will use the
following prioritized list of authorized weather sources
11-202v3

Answer 5

• 4.10.1.2. Regional Operational Weather Squadron (OWS).
• 4.10.1.3. Other DoD military weather sources (e.g., U.S. Navy weather facilities).
• 4.10.1.4. Other U.S. Government (USG) weather facilities or services (e.g., National Weather Service, FAA).
• 4.10.1.4. (AETC) Aircrews will use only DoD or USG weather sources and/or flight planning services (T-2). Note: This includes Flight Service Stations and/or services.
• 4.10.1.4.1. (Added-AETC) Commercial applications (i.e., Foreflight) which provide weather information obtained from approved sources are acceptable. Only MAJCOM-approved EFB applications will be used (T-2).
• 4.10.1.5. Foreign civil or military weather service (use only when DoD military resources or USG services are unavailable in outside the continental U.S. [OCONUS] locations).

Question 6

When to file a flight plan (4.5)

11-202v3

Answer 6

• For local area flights that depart and terminate at the home or auxiliary field, aircrews may use AF Form 4327, ARMS Fighter Flight Authorization or AF Form 4327a, Crew Flight (FA) Authorization.
• The PIC may make changes to the original filed flight plan without re-filing provided the change does not penetrate an air defense identification zone (ADIZ), the controlling ATC agency approves the change for an IFR flight, or the changes comply with applicable host-nation rules.
• 4.5.4. [NAS Only] When landing at a non-towered civilian airfield or part-time-towered airports when the control tower is not operating, the pilot is responsible for ensuring that flight plans are closed either by contacting a FSS, the originating airfield management, or through an ATC facility

Question 7

Who signs the flight plan (4.5.5)

11-202v3

Answer 7

The act of accepting the aircraft tail number from the duty desk by the PIC signifies compliance with this paragraph for units using the Graduate/Training Integration Management System.

Question 8

When can a destination be filed to (4.15)

11-202v3

Answer 8

• Do not depart IFR unless the weather conditions at the destination, from 1 hour before to 1 hour after the estimated time of arrival (ETA), is forecast to be at or above the lowest compatible published approach minimums. (T-1) Note: Temporary (TEMPO) conditions may be below compatible published approach minimums. Exception: MAJCOMs may authorize filing to a destination with weather below the lowest compatible published approach minimums after publishing supplemental recovery procedures
• For a straight-in or sidestep approach, the forecast weather must meet required visibility minimums.
• For a circling approach, the forecast weather must meet both the ceiling and prevailing visibility minimums.
