What are the aircrew flight restrictions related to crew rest?
Aircrew will not fly if:
* Appropriate crew rest was not obtained
* Any alcohol consumed within 12 hours prior to takeoff
* Impaired by alcohol or any intoxicating substances
* Physical or psychological condition is detrimental to safe performance
* Self-medicating unless in accordance with DAFMAN 48-123
* Within 72 hours of donating blood, plasma, or bone marrow
* Within 24 hours of compressed gas diving
Specific conditions related to crew rest must be adhered to ensure safety.
How long must crew rest be before the flight duty period (FDP)?
Crew rest must be a minimum of 12 non-duty hours before the FDP begins.
Crew rest includes time for meals, transportation, and uninterrupted sleep.
What happens if crew rest is interrupted?
If crew rest is interrupted, the aircrew must notify the PIC and begin a new crew rest period or refrain from flying.
Official business conducted after crew rest may interrupt the rest period.
When does the Flight Duty Period (FDP) begin and end?
FDP begins when an aircrew member first reports for official duty and ends at final engine shutdown after the final flight.
The PIC can extend FDP a maximum of 2 hours for unplanned mission delays.
What is the definition of IMC?
IMC = weather conditions with visibility and ceilings less than the minima specified for VMC.
IMC refers to conditions that require instrument flight rules (IFR).
What are the priorities for weather sources?
- MAJCOM-approved weather source
- Regional Operational Weather Squadron (OWS)
- Other DoD military weather sources
- Other U.S. Government weather facilities
- Foreign civil or military weather service (only when DoD or USG services are unavailable)
AETC aircrew must only use approved weather sources for planning.
When must a flight plan be filed?
File a flight plan in accordance with FLIP GP or MAJCOM guidance, or once airborne as soon as practicable if unable to file on the ground.
Mission requirements determine the selection of flight rules (VFR/IFR).
Who is responsible for signing the flight plan?
The PIC signs the flight plan.
The PIC is ultimately responsible for the flight plan’s accuracy and compliance.
When is an alternate airport required?
An alternate is required when:
* No compatible instrument approach is available
* Weather forecast within +/- 1 hour from ETA is below minimums
* Crosswinds are out of limits
* Denial of RVSM prevents non-RVSM compliant aircraft from reaching the destination
Additional considerations for alternate include weather reporting capabilities and approach minimums.
What disqualifies an alternate airport?
An alternate is disqualified if:
* Weather within +/- 1 hour ETA is below 1000/2 or 500 above and 1 mile above lowest compatible mins
* No compatible instrument approach procedure published
Weather conditions and approach availability are critical for alternate airport selection.
When should minimum or emergency fuel be declared?
Declare ‘minimum fuel’ or ‘emergency fuel’ when the aircraft may land with less than the MDS-specific minimum reserve or emergency fuel.
Specific fuel amounts for T-6 are 150/100.
What is the fuel reserve requirement?
Ensure enough usable fuel to increase total planned flight time by 10% or a minimum of 20 minutes, whichever is greater.
Fuel reserves must be computed using MAJCOM-defined consumption rates.
What is the minimum weather requirement for IFR departure?
Do not depart IFR unless weather at destination +/- 1 hour ETA is at or above the lowest compatible approach minimums.
Temporary conditions may be below minimums.
What is the standard IFR climb gradient?
The standard IFR climb gradient is 200 feet per nautical mile.
This is the minimum required climb performance for IFR departures.
What are Obstacle Departure Procedures (ODPs)?
ODPs are IFR departure procedures specifically designed for obstacle avoidance, described in the ‘Trouble T’ section of terminal procedures.
These procedures ensure safe clearance from obstacles during departure.
What is the purpose of a Standard Instrument Departure (SID)?
A SID simplifies clearance delivery procedures and assists in meeting environmental, capacity, and ATC requirements.
SIDs are published for specific airfields and require ATC clearance to fly.
What are takeoff obstacle notes?
Takeoff obstacle notes identify obstacles within 3SM of the DER requiring a climb gradient greater than 200 ft/nm.
These notes alert pilots to the height and location of obstacles.
What defines low close-in obstacles?
Low close-in obstacles require a climb gradient above 200 ft/nm for a short distance, only until the aircraft reaches 200 feet above the DER.
These obstacles pose a risk during the initial climb phase.
What are takeoff obstacle notes?
Obstacles within 3SM of the DER that require a climb gradient greater than 200 ft/nm.
Published under “TAKEOFF OBSTACLE NOTES” to alert pilots about height and location of obstacles.
Define low close-in obstacles.
Obstacles that require a climb gradient above 200 ft/nm for a very short distance until the aircraft is 200 ft above DER.
When is supplemental oxygen use required?
When cabin pressure altitude exceeds 10,000 feet MSL.
What is the right of way rule for aircraft in distress?
Aircraft in distress have right-of-way over all other air traffic.
List the right-of-way hierarchy for different aircraft categories.
- Balloons
- Gliders
- Aircraft towing or refueling other aircraft
- Airships
- Rotary or fixed wing aircraft
What is the minimum IFR altitude when flying off airway?
At least 1,000 feet above all obstacles within 4NM in non-mountainous terrain or 2,000 feet in mountainous terrain.
