Blue shirts
Angle between the chord line of a wing or airfoil and the direction of the relative wind or airflow is called:
Angle of attack
A wall or vertical surface within a ship is called a:
Bulkhead
Conventional fixed-wing aircraft is controlled around its longitudinal axis __1__ by means of the :____2____
1) Roll, 2) ailerons
Elevators control movement around the: _________
lateral axis (pitch)
The rudder controls movement around the: _________
vertical axis (yaw)
Flaps are used for:
increasing both lift and drag, and normally used during takeoffs and landings
1 nautical mile is equal to how many statute miles
1.15 statute miles
1 knot is equal to
one nautical mile per hour (measure of speed)
The altimeter typically shows the height of the aircraft above a particular pressure level in:
Thousands of feet
When a pilot pulls back on the control stick, the elevators will move in which direction?
Move upward. This pushes the tail of the aircraft downward and the nose upward
Order given to the helmsman to align the rudder with the keel of the ship is:
“Rudder amidships”
VFR stands for
Visual Flight Rules–visually establishing the aircraft’s attitude with reference to the natural horizon
1 nautical mile is approximately how many feet?
6,076 feet
The bridge of a ship is where:
all orders and commands affecting the ship originate
The Latin phrase Semper Paratus is the motto of:
The US Coast Guard–“Always Ready”
The Marine corps motto is
Semper Fidelis (“Always Faithful”)
On an aircraft carrier, the standard watch length for the Officer of the Deck is:
4 hours
What is the “Pri-Fly”
the control tower for flight operations on an aircraft carrier
The front section of a ship is known as a
Bow
The rear section of a ship is known as the
Stern
The right hand side of a ship is known as the
Starboard side
Left hand side of a ship is known as the
Port side
The section of the upper deck of a ship located at the bow
Forecastle
Body of a ship excluding masts, sails, yards, and riggings
The hull
Adverse yaw device
Ailerons, spoilers, and rudders, which are used to counteract adverse yaw in aircraft
Basic weight
The weight of the basic aircraft plus weapons, unusable fuel, oil, ballast, survival kits, oxygen, and any other internal or external equipment on board the aircraft that will not be disposed of during flight.
Operating weight
The sum of basic weight and items such as crew, crew baggage, steward equipment, pylons and racks, emergency equipment, special mission fixed equipment, and all other nonexpendable items not included in basic weight.
Gross weight
The total weight of an aircraft, including its contents and externally mounted items, at any time
Zero Fuel Weight (ZFW)
The weight of the aircraft without any usable fuel
Landing Gross Weight
The weight of the aircraft, its contents, and external items when the aircraft lands
Profile drag or parasitic drag
Experienced by all objects in an airflow, and is caused by resistance to the airplane pushing the air out of the way as it moves forward.
Induced drag
Result of the production of lift
Flight attitude
Position in flight
Longitudinal axis of an airplane
Axis that runs lengthwise through the fuselage from the nose to the tail
Lateral axis
axis that runs from wingtip to wingtip
Roll
Movement around the airplane’s longitudinal axis
Pitch
Movement around its lateral axis
Yaw
Movement around the vertical axis
Three control surfaces:
- Rolls is controlled by the ailerons
- Pitch is controlled by the elevators
- Yaw is controlled by the rudder
Primary control systems
Those needed to safely control an airplane during flight: ailerons, elevator/stabilator, and rudder
Secondary control systems
Wing flaps, and trip control systems, improve the airplane’s performance or relieve the pilot from having to wrestle with excessive control forces
Indicated Altitude
The uncorrected altitude read directly from the altimeter when it is set to the current altimeter setting
True Altitude
The vertical distance of the airplane above sea level; the actual altitude. It is often expressed as feet above mean sea level (MSL); airport, terrain, and obstacle elevations on aeronautical charts are true altitudes
Absolute Altitude
The vertical distance of an airplane above the terrain, or above ground level
Pressure altitude
The altitude indicated when the altimeter setting window (barometric scale) is adjusted to 29.92. This is the altitude above the standard datum plane, which is a theoretical level where air pressure (corrected to 15C) equals 29.92 inches of mercury (Hg). Pressure altitude is used to compute density altitude, true altitude, and other performance data.
Density altitude
This altitude is pressure altitude corrected for variations from standard temperature. When conditions are standard, pressure altitude and density altitude are the same. If the temperature is above standard the density altitude is higher than pressure altitude. If the temperature is below standard, the density altitude is lower than pressure altitude. This is an important altitude because it is directly related to the airplane’s performance.
4 airspeed types
ICE-T:
1. Indicated airspeed
2. Calibrated airspeed
3. Equivalent airspeed
4. True airspeed
Indicated airspeed
Measures air pressure reading from the pitot tube
Calibrated airspeed
Airspeed calculated after accounting for aircraft mechanical and position errors (attitude)
Equivalent airspeed
Airspeed calculated after compensating for compression effects; usually only needed at speeds over 200mph.
True airspeed
Airspeed calculated after accounting for temperature and atmospheric pressure changes
White arc
This arc is commonly referred to as the flap operating range, since its lower limit represents the full flap stall speed and its upper limit provides maximum flap speed. Approaches and landings are usually flown at speeds within the white arc
Lower limit of white arc
The stall speed or the minimum steady flight speed in the landing configuration. In small airplanes, this is the power-off stall speed at the maximum landing weight in the landing configuration (gear and flaps down).
Upper limit of white arc
The maximum speed with the flaps extended
Green arc
Normal operating range of the airplane; most flying occurs within this range
Lower limit of green arc
The stall speed or minimum steady flight speed in a specified configuration; for most airplanes, this is the power-off stall speed at the maximum takeoff weight in the clean configuration (gear up if retractable, and flaps up)
Upper limit of green arc
The maximum structural cruising speed; do not exceed this speed except in smooth air.
Yellow arc
Caution range; fly within this range only in smooth air, and then only with caution
Red line
Never-exceed speed; operating above this speed is prohibited, because it may result in damage or structural failure
Magnetic compass
The only direction-seeking instrument in the airplane
30 degree interval on a magnetic compass appears as:
3
300 degrees on a magnetic compass appears as a:
30
