. 7600 (failure of radio communications)

. 7700 (emergency)

It is important to prevent accidental selection of one of these codes when moving from one code setting to another.
 
C.4.  Instruments
 Air crew should be able to read and know the location of some of the basic instruments such as the:
. Altimeter

. Heading indicator

. Magnetic compass

. Attitude indicator

. Airspeed indicator

. Tachometer

. Oil pressure indicator

. Oil temperature indicator

. Ammeter

. Fuel gauges

. Fuel pressure

. Landing gear indicator lights

 
C.5.  Aircraft Communications
 Communication procedures used for ATC differ from those used for Coast Guard communications; air crew must know both.  Not only should air crew know what the communications procedures are, but also how to find the proper frequencies to use and the correct terminology for operation.  Aircraft specific communications include:
. Clearance delivery

. Ground control

. Tower

. Departure and approach control

. Center

. Flight service

. Unicom

 
C.6.  Navigation Skills
 In addition to what the observer has been taught to read and understand regarding sectionals and terminal charts, air crew should be able to:
. Interpret the chart legend.

. Find frequencies of interest.

. Define special use airspace.

. Plot a course using sectional charts.

. Do time and distance calculations.

. Identify on the sectional and be familiar with the various types of airspace such as: *
Class A, B, C, D, E, and G
*
 Military Operating Areas (MOAs)
*
 Restricted Areas
*
 Air Defense Identification Zones (ADIZ)
*
 Prohibited Areas

. Use low altitude enroute charts and approach plates in addition to the sectional charts.

. Back up the pilot in all phases of flight in regards to heading, altitude, and communications frequencies.

 
C.7.  Weather
 Air crew should be able to use and interpret:
. Automatic Terminal Information Service (ATIS)

. Automated Weather Observation Service (AWOS)

. Automated Surface Observation Service (ASOS)

. Automated Flight Service Station (AFSS)

. Direct User’s Access Terminal (DUAT)

. Aviation Routine Weather Report (METAR)

. Aerodrome Forecasts (TAF)

. Winds Aloft (FD)

. Notice to Airmen (NOTAMS)

. NOAA

 
C.7.a.  National Oceanic and Atmospheric Administration
 Marine weather as received on the weather frequencies of most marine radios is useful in obtaining an overall weather picture.  Important information includes sea conditions, the presence of fog, the presence and movement of thunderstorms, and forecast surface winds for the over water areas.  This information is neither current nor complete enough to satisfy all of the requirements of aviation.  Marine weather does not include ceilings (the lowest layer of broken or overcast layer of clouds), visibility, or the temperature/dew point spread.  The air crew should listen to the transcribed NOAA marine weather and pass on to the pilot any significant information, which could affect the mission.
