Term
WHAT ARE THREE FACTS ABOUT A FORWARD CG?
Definition
Longer Takeoff Distance
Decreased Climb Rates
Slower Cruise Speeds
Term
WHAT ARE THREE FACTS ABOUT A AFT CG?
Definition
Shorter Takeoff Distances
Increased Climb Rates
Faster Cruise Speeds
Term
Air Density can be affected in three ways. WHAT ARE THEY? PTH...
Definition
Change in Pressure (Pressure Altitude)
Change in Temperature(Density Altitude)
Change in Humidity
Term
WHAT IS THE FORMULA FOR PRESSURE ALTITUDE?
Definition
29.92-current altimeter setting x 1000 + Field Elevation = Pressure Altitude
Term
WHAT IS DENSITY ALTITUDE?
Definition
Pressure Altitude corrected for non-standard temperature (15º C)
Main effect on performance!
Term
GRASSY RUNWAYS DO WHAT TO TAKEOFF DIST AND LANDING DIST.?
Definition
Increase takeoff distance
Increase landing distance
Term
What is calibrated airspeed?
Definition
Indicated airspeed corrected error
Term
Ground Roll IS?
TOTAL DISTANCE IS?
Definition
A-Distance from the start of acceleration to where the aircraft leaves the ground
B- GROUND ROLL PLUS DISTANCE TO CLEAR 50'
Term
WHAT ARE THREE FACTORS IN TAKEOFF PERFORMANCE?
Definition
Weight
Center of Gravity
WIND
Term
WHAT IS VX AND VY?
Definition
VX- BEST ANGLE OF CLIMB
Greatest gain in altitude over the shortest distance

VY- BEST RATE OF CLIMB
Greatest gain in altitude over the shortest time
Term
WHY WOULD YOU USE CRUISE CLIMB AND WHAT IS IT IN THE WARRIOR?
Definition
Increases Ground Speed
Increases Forward Visibility
Better Engine Cooling
ITS 87 KNOTS
Term
DIFFERENCE BETWEEN ABSOLUTE AND SERVICE CEILING?
Definition
ABSOLUTE- IS AS HIGH AS YOU CAN GO. CANT CLIMB ANYMORE
SERVICE- POINT WHERE YOUR MAX RATE OF CLIMB IS 100 FPM
Term
Normal Power Settings – 55% to 75%
Which power setting will you use? Why?
Definition
NORMALLY WE WILL USE SOMETHING LIKE 55 BUT 65 WOULD WORK TOO. 75 BURNS LOTS OF GAS AND HAS DOES MORE WEAR AND TEAR TO THE A/C
Term
WHAT ARE SOME CRUISE ALTITUDE CONSIDERATIONS?
Definition
FAA, CLOUDS, TERRAIN, TURBULANCE
Term
WHAT IS RANGE AND WHY WOULD WE NEED IT??
Definition
TOTAL DISTANCE AN A/C CAN TRAVEL AND WE MAY USE IT IN AN EMERGENCY OR TO GET AWAY FROM WEATHER
Term
WHAT IS ENDURANCE?
Definition
GREATEST AMOUNT OF TIME THE A/C CAN STAY IN THE AIR
Term
WHAT IS GUST FACTOR? HOW DO WE GET IT?
Definition
TAKE GUST AMOUNT MINUS THE ACUALLY WIND AND THATS YOUR GUST FACTOR
Term
FOUR FORCES OF FLIGHT?
Definition
LIFT, WEIGHT, THRUST, DRAG
Term
WHAT AOA?
Definition
CHORD LINE OF WING WITH RELITIVE WIND
Term
WHAT IS ANGLE OF INCIDENT?
Definition
CHORD LINE WITH LONGITUDINAL AXIS
Term
CREATION OF LIFT IS BASED ON WHAT TWO PRINCIPLES?
Definition
NEWTONS 3RD LAW
BERNOULLI'S PRINCIPLE
Term
WHAT IS BERNOULLI'S PRINCIPLE?
Definition
AS FLUID INCREASES PRESSURE DECREASES
Term
NEWTONS 3RD LAW IS?
Definition
TO EVERY FORCE THERE IS A CORRESPONDING FORCE
Term
NEWTONS 3RD LAW IS?
Definition
TO EVERY FORCE THERE IS A CORRESPONDING FORCE
Term
WHAT 6 FACTORS EFFECT LIFT?
Definition
PLANFORM, CAMBER, AIR DENSITY, VELOCITY, AOA, FLAPS
Term
WHAT IS ASPECT RATIO?
Definition
WINGSPAN DIVIDED BY AV. CHORD
Term
A STALL IS?
Definition
WHEN AIRFLOW OVER THE WING BECOMES TURBULENT
Term
WHAT ARE 4 FACTORS THAT EFFECT STALL SPEED>?
Definition
WEIGHT
CG
FLAPS
POWER
Term
PARASIT DRAG HAPPENS AT WHAT FLAP RANGE AND THERE ARE THREE TYPES OF THIS?
Definition
40 DEGREES AND THE DIFFERENT TYPES ARE SKIN FRICTION, FORM, AND INTERFERENCE
Term
INDUCED DRAG HAPPENS AT WHAT FLAP RANGE?
Definition
10-25 DEGREE
Term
2 EFFECTS OF A FORWARD CG?
Definition
HEAVY NOSE AND MORE TAIL DOWN FORCE NEEDED
Term
2 EFFECTS OF A AFT CG?
Definition
TAIL HEAVY AND LESS TAIL DOWN FORCE NEEDED
Term
WHAT ARE THREE FORCES OF A TURN?
Definition
WEIGHT, TOTAL LIFT, CENTRPITAL FORCE
Term
WHATS THE DIFFERENCE IN RATE OF TURN AND RADIUS OF TURN?
Definition
RATE OF TURN ID THE SPEED AND RADIUS OF TURN IS AREA
Term
WHATS DUTCH ROLL?
Definition
ROLL DUE TO YAW
Term
WHATS ADVERSE YAW?
Definition
YAW DUE TO ROLL
Term
WHAT IS A SKID?
Definition
INSUFFICIENT BANK ANGLE, TOO MUCH RUDDER
Term
WHATS A SLIP?
Definition
EXXCESSIVE BANK ANGLE, TOO LITTLE RUUDER
Term
SPIN IS? AND WHAT ARE THE THREE PHASES?
Definition
UNCOORDINATED STALL
1. INCIPIENT
2. DEVELOPED
3. RECOVERY
Term
WHAT EFFECTS VORTEX STRENGTH? LIST 3
WHAT PRODUCES THE STRONGEST VORTEX?
Definition
SPEED, WEIGHT, AOA
HEAVY CLEAN AND SLOW
Term
WHAT ARE VA SPEEDS WITH THE WEIGHTS?
Definition
88-1531 AND 111-2440
Term
WHAT IS P-FACTOR?
Definition
AS PITCH CHANGES SO DOES THE ORIENTATION OF THE PROP
Term
WHAT ARE THE 3 THINGS THAT FIX LEFT TURNING TENDANCIES?
Definition
ENGINE AND RUUDER OFFSET, WING TWIST
Term
WHATS THE DIFFERENCE IN STATIC AND DYNAMIC STABILITY?
Definition
STATIC IS THE INITIAL TENDANCY WHILE DYNAMIC IS THE TENDENCY OVER TIME TO CORRECT ITSELF
Term
WHAT ARE THE 3 DESIGN CHARACTERISTICS OF LATERAL STABILITY?
Definition
DYHEDRAL
KEEL EFFECT
