Cards in this set: 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?
