Standard weights have been established for numerous items used in weight and

At a controlled airport, the light signal used by the tower to warn an aircraft in flight that
the airport is unsafe and not to land is a(n):
- alternating red and green
- flashing green
- flashing red
- steady green
- steady red - ANS-flashing red

- blue
- green
,- red
- white
- yellow - ANS-white
Which type of rope is the strongest?
- cotton
- hemp
- manila
- nylon
- sisal - ANS-nylon
An unlighted buoy, used to mark the LEFT side of a channel when facing inland, is
called a:
- bell buoy
- can buoy
- nun buoy
- spar buoy
- whistle buoy - ANS-can buoy
The International Date Line is located at:
- the 0 meridian
- the 180th meridian
- the celestial meridian
- Greenwich, England
- the prime meridian - ANS-the 180th meridian
The Beaufort scale is generally used at sea in estimating:
- wind direction
- wind speed
- atmospheric pressure
- relative humidity
- water depth - ANS-wind speed
When a person is reported overboard, the action to take first is to:
- bring the ship to a halt
- track the person with a pair of binoculars
- throw life buoys over at once
- turn the ship around 180 degrees
- reduce the ship's speed - ANS-throw life buoys over at once
At sea, the time zones are generally bands of longitude:
,- 7 1/2 degrees in width
- 15 degrees in width
- 24 degrees in width
- 30 degrees in width
- 45 degrees in width - ANS-15 degrees in width
Which of the following is NOT considered to be an "aid to navigation"?
- buoys
- fog signals
- lightships
- loran
- mountain peaks - ANS-mountain peaks
Fog is generally formed when:
- cold air moves over cold water
- cold air moves over hot water
- colder air moves over warmer water
- warm air moves over warm water
- warmer air moves over colder water - ANS-warmer air moves over colder water
An unlighted buoy, used to mark the RIGHT side of a channel when facing inland, is
called a:
- bell buoy
- can buoy
- gong buoy
- nun buoy
- spar - ANS-nun buoy
Ships or boats are steered by one or more rudders at the stern. The faster the vessel is
moving:
- the GREATER the pressure against the rudder and the QUICKER the turning effect
- the GREATER the pressure against the rudder and the SLOWER the turning effect
- the LESS the pressure against the rudder and the QUICKER the turning effect
- the LESS the pressure against the rudder and the SLOWER the turning effect
- none of the above - ANS-the GREATER the pressure against the rudder and the
QUICKER the turning effect
The angle between the chord line of a wing or airfoil and the direction of the relative
wind or airflow is called the:
- angle of pitch
, - degree of roll
- angle of deflection
- angle of attack
- degree of yaw - ANS-angle of attack
A wall or vertical surface within a ship is called a:
- bulkhead
- bilgeway
- gangway
- keel
- frame - ANS-bulkhead
A conventional fixed-wing aircraft is controlled around its longitudinal axis by means of
the:
- ailerons
- elevators
- rudder
- trim tab
- flaps - ANS-ailerons
Two statute miles are equal to:
- 2.0 nautical miles
- 1.74 nautical miles
- 2.3 nautical miles
- 2.3 knots
- 2.0 knots - ANS-1.74 nautical miles
The altimeter typically shows the height of the aircraft above a particular pressure level
in:
- feet
- hundreds of feet
- thousands of feet
- hundreds of meters
- thousands of meters - ANS-thousands of feet
The time of 7 PM would be expressed using the 24-hour clock as:
- 0700
- 1400
- 1700
- 1900
- none of the above - ANS-1900
