Aviation and Nautical Info Flashcards
Gallon of oil equals how many lbs?
7.5 lbs
How many feet in a nautical mile?
6076ft
Gallon of water equals how many lbs?
8.35 lbs
Gallon of gas equals how many lbs?

RRRNEI
Red, right, returning, nun, even, increasing.
Waterline to deck is called:
Freeboard.
Fore-half of deck:
Forecastle.
Aft-half of deck:
Fantail.
Lights on port side:
Red.
Lights on starboard side:
Green.
Swept wings:
Reduced drag at high speeds.
Extended wings:
1) increased lift at low speeds; 2) decreased ground speed during landing.
Vertical axis:
Yawing.
Wet-bulb depression and fog:
When wet-bulb depression is less than 4 degrees, fog is likely.
Courseline
Line in which ship is heading.
Front of boat:
Bow.
Backside of boat:
Stern.
Nautical mile vs statute mile:
8 NM = 7 statute miles
Lubber’s line:
The bow line.
Longitudinal axis:
Banking.
In front of:
Fore.
Lateral axis:
Pitching.
Waterline to deck:
Freeboard.
Behind:
Aft.
When is a plane most likely to stall?
1) high angle of attack; 2) when banking hard.
Father of Navy
John Paul Jones.
Camber
Curvature at the top of airfoil.
Angle of attack
The angle formed by the chord line and the oncoming air.
Dead reckoning
Navigation only by compass.
Aspect ratio
Ratio of wingspan vs. average wing width
Aspect ratio formula
Aspect ratio = (wingspan)2 / surface area = b² / s
b = wing span
s = surface area of wing
High aspect ratio
Long & skinny wings
Low aspect ratio
Shot & stubby wings
Wingload
Ratio of wing surface area vs. aircraft weight
Trim tabs
Small control surfaces on larger control surfaces. They permit the pilot to balance control forces in steady flight, thereby relieving pressure on aircraft control and on the pilot.
Compass deviation
The error of a magnetic compass due to local magnetism.
Variation (in navigation)
The difference between true bearing and magnetic bearing.
RIO
Radar Intercept Officer.
E.g. Goose in Top Gun.
Perigree
When the moon or a satellite is closest to Earth.
Apogee
When the moon or a satellite is farthest from Earth.
N at the end of _____, _____, and ____ means nuclear powered.
N at the end of CV, SS, and CG means nuclear powered.
CG
Guided missile cruiser.
CA
Gun cruiser.
CV
Aircraft carrier.
L
Amphibious/landing craft carriers.
E.g. USS Ogden.
BB
Battleship.
S
Submarine.
A
Combat logistics.
M
Mine warfare.
First conflict to see wide use of helos?
Korean War (1950-1953).
Yawl
Double-mast sailing vessel where the mizzen (rear-mast) is aft (behind) of the rudder.
Sloop
A single-mast sailing vessel.
Spring tide
–At, or soon after, new/full moons. –High tides are very high, low tides are very low.
Neap tide
–Between spring tides, i.e. between new/full moons. –Smaller variance between low and high tides.
Ebb tide
When the tide falls after high tide.
