Navigation Flashcards
What is proper crew rest?
12-hour rest opportunity prior to beginning the flight duty period
Alcohol rule?
12 hour bottle to throttle or if impaired by alcohol or any other intoxicating substance (effects and after-effects)
When will a physical or psychological condition prevent one from flying?
When it is detrimental to the safe performance of flight duty
Is self-medicating permitted for flight ops?
No, unless cleared IAW para 3.7.2
Blood, plasma or bone marrow donation DNIF
72 hours
Compressed gas diving (SCUBA), surface supplied diving, aircraft pressurization checks exceeding 10 minutes in duration below sea level or hyperbaric chamber exposure DNIF
24 hours
What is crew rest?
free time and includes time for meals, transportation, opportunity for 8 hours of uninterrupted sleep.
cannot begin until the completion of official duties
it is compulsory; minimum of 12 hours
When can crew rest be reduced to 10 hours?
3 or more consecutive FDPs of at least 12 hours are scheduled to maintain a 24 hours work/rest schedule; used for 24 hour clock cycles, not convenience
What is required for any reduction in the 12 hour crew rest period?
Transportation, meals and quarters for 8 hours of uninterrupted rest
When does the FDP begin and end?
When air crew first reports for official duty and ends at final engine shutdown after the final flight of the completed mission
How long can the FDP be extended for unforeseen delays?
2 hours
Consider reducing the FDP when?
post-flight duties may exceed 2 hours
Instrument Flight Rules (IFR)
NAS only, term used by pilots and controllers to indicate flight plan type
Also indicates weather conditions that are less than VFR minimum requirements
Instrument Meteorological Conditions (IMC)
conditions (vis, distance from clouds and ceilings) less than VMC minima
Visual Flight Rules (VFR)
procedures for conducting flight under visual conditions
used in US to indicate conditions equal to or greater than min VFR requirements; also type of flight plan
Visual Meteorological Conditions (VMC)
conditions (vis, distance from clouds and ceilings) equal to or better than specified minima
Weather Information Prioritization
MROOF
- MAJCOM-approved weather source (OSS)
- Regional Operational Weather Squadron (OWS)
- Other DOD weather sources
- Other US Government weather facilities/services
- Foreign civil or military services if above options aren’t available
When to file a flight plan?
Either on the ground or airborne whenever practicable (IFR or VFR)
Who signs the flight plan?
The PIC
When can a destination be filed to?
- When weather conditions at destination +/- 1 hour from ETA is forecasted to be at or above the lowest compatible published approach minimums
- TEMPO conditions may be below this criteria
- MAJCOMs may authorize filing below this minima with appropriate recovery procedures
When is an alternate required?
(Think backup plan/fuel)
- compatible instrument approach procedure is not available at the destination airfield
- weather forecast +/- 1 hour from ETA at destination including TEMPO conditions are less than 2,000 ft AGL ceilings, 3SM and winds are out of limits.
What disqualifies an alternate?
- unmonitored navaid
- does not report weather observations
- alternate note authorized (ANA symbol)
- any not disqualifying the airfield/ compatible approaches in the “A IFR Alt Mins” section
When to declare min/emer fuel?
When aircraft may land at intended destination with less than MDS-specific minimum reserve or emergency fuel
Fuel reserves requirements?
Enough usable fuel to increase total planned flight time between refueling points by 10% (up to a maximum of 45 minutes) or 20 minutes, whichever is greater
Alternate fuel requirements?
- fuel required for an approach and missed approach at intended destination if vis only weather criteria is used at destination
- fuel required for missed is not required when ceiling and vis criteria is used
Minimum weather for departure (IFR)
- When weather conditions at destination +/- 1 hour from ETA is forecasted to be at or above the lowest compatible published approach minimums
- TEMPO conditions may be below this criteria
- MAJCOMs may authorize filing below this minima with appropriate recovery procedures
Circling approach requirements
forecast weather must meet both ceiling and prevailing vis minimums
Leading level offs?
- pitch corrections = VVI of 1x to 2x the amount of altitude deviation prevents overshoots
- begin pitch change to level off 10% of the VVI rate
IFR climb performance
- ensure aircraft can meet/exceed climb gradient of 3.3% or 200fpm or published climb gradient, whichever is higher
- all engines operating to enroute structure or altitude at or above minimum IFR altitude within the enroute structure (1000ft above tallest obstacle within 4nm of the course to be flown)
Minimum turn altitude after takeoff?
400 feet above DER altitude, unless required by published procedure/ATC
What do published/ATC climb gradients not account for?
Low close-in obstacles; low close-in obstacle clearance not assure when complying with IFR climb gradients
IFR DER crossing restrictions
- TERPS = 0ft
- ICAO = 16ft
- NAS (hardened >/= 6000ft) = 0ft
- NAS (Unhardened Rwy + Rwy < 6000ft) 0-35ft
How is an obstacle departure procedure (ODP) described in the Trouble T section?
- OBSTACLE is included in the procedure title
- Aircraft cannot be vectored off of an ODP/issued altitude lower than published ODP altitude until at min vectoring altitude (MVA) or min IFR altitude
When will a pilot not fly a diverse departure? (ODP)
- When a standalone graphic ODP is present
- published ODP listed in Trouble T section of the terminal procedures publication
What is the obstacle identification surface surface ratio/climb gradient?
OIS is equivalent to 152 feet per nautical mile or 40:1
Non-standard IFR takeoff Minimums
- provided for pilots to see and avoid obstacles when they penetrate 40:1 OIS within 3SM from DER
- wx must be at least published minimums for departure (ceiling and vis)
- climb gradient of 200ft/NM or greater
Visual Climb Over Airport (VCOA)
departure for IFR aircraft operating in VMC wanting to conduct climbing turns over the airfield
Reduced Takeoff Runway Length Procedure (RTRL)
- artificial limit of TO distance available due to obstacles penetrating OIS by 35 feet or less to achieve standard climb gradient
Diverse Vector Area (DVA)
- created to use radar vectors in lieu of an ODP when an ODP has already been established
- assessed for departures without a specified ground track
Specific ATC Departure Instructions
- include a heading and altitude
- do not apply wind drift corrections
- must be above
Standard Instrument Departure (SID)
- simplifies clearance delivery procedures
- provide protection from obstacles
- are not ODPs and may not be flown unless approved by ATC
- Heavy black line = SID
- thin black line = transition route
- higher than standard climb gradients are published on the SID
- if unable to fly SID, include “NO SID” in flight plan
- adhere to published speed restrictions
MAJCOM Certified Procedures
- created for restricted areas/contingency operations
- for specific aircraft at specific locations w/
- MAJCOM-specific training required before flying
What are Takeoff Obstacle Notes (climb gradient/distance required)
- obstacles within 3SM of DER/climb gradient greater than 200 ft/NM
- listed in the “TAKE-OFF OBSTACLE NOTES” in the trouble-T section
- obstacles to be seen and avoided
What are low close-in obstacles?
- Obstacles requiring a climb gradient greater than standard for a very short distance, only until the aircraft is 200 feet above the DER
When is supplemental oxygen use required?
- Supplemental O2 will be used anytime the cabin pressure exceeds 10,000 ft
- Cannot operate above 14’000 feet MSL without supp. O2
- Not exceed 1 hour between 10,000 and 12,500 without supp. O2
- Not exceed 30 minutes between 12,500 and 14,000 without supp. O2
- Supp O2 will be used by all occupants operating between 14000 and FL250
