AERODYNAMICS Flashcards
You are flying a jet airplane at FL 360 and the SAT indicates – 50 degrees C. Which of the following should you expect:
Higher DA and lower flight performance.
Lower DA and lower flight performance.
Higher DA and higher flight performance.
Lower DA and higher flight performance.
Higher DA and lower flight performance.
-50 IS WARMER SO LESS PERF.
Assuming a normal 3 degree glidepath, a height of 100 feet instead of 50 feet over the runway threshold will result in touchdown:
100 feet beyond the 1000 foot mark.
400 feet beyond the 1000 foot mark.
900 feet beyond the 1000 foot mark.
1400 feet beyond the 1000 foot mark.
900 feet beyond the 1000 foot mark.
YOUR ABOUT DOUBLE HIGH SO I GUESS YOU LAND ABOUT DOUBLE LONG.
WHAT EFFECT DOES ALTITUDE HAVE ON STALL SPEED
VERY LITTLE
STALL SPEED WILL INCREASE DRAMATICALLY DUE TO COMPRESSIBILITY EFFECTS
STALL SPEED WILL INCREASE SLIGHTLY
STALL SPEED WILL DECREASE SLIGHTLY
STALL SPEED WILL INCREASE SLIGHTLY
2 different answers from RST but this one is in Capitals.
IN A BOEING 737, YOU HAVE LOST THE #2 ENGINE ON TAKEOFF. YOU ELECT TO RETURN TO YOUR DEPARTURE AIRPORT WHICH HAS ONE RUNWAY, 9-27. THE WINDS ARE 180 DEGREES AT 12 KNOTS. WHICH RUNWAY WOULD YOU CHOOSE FOR LANDING PURPOSES
27, DUE TO CROSSWIND AIDING IN DIRECTIONAL CONTROL
9, DUE TO CROSSWIND AIDING IN DIRECTIONAL CONTROL
27, DUE TO INCREASED RUDDER EFFECTIVENESS
9, DUE TO LESS EFFECTIVE CROSSWIND COMPONENT
27, DUE TO CROSSWIND AIDING IN DIRECTIONAL CONTROL
YOU ARE TAKING OFF IN A BOEING 747 ON RUNWAY 27 WITH WINDS OF 230 DEGREES AT 19 KNOTS. ALL THINGS BEING EQUAL, WHAT WOULD YOU CONSIDER THE CRITICAL ENGINE(S) TO BE.
THE #1 ENGINE
THE #4 ENGINE
JET AIRCRAFT DO NOT DESIGNATE CRITICAL ENGINES
EITHER STARBOARD SIDE ENGINE
THE #1 ENGINE
BAD ENGINE INTO WIND IS MOST CRITICAL. I WAS CONFUSED ABOUT THIS. I GUESS JUST REMEMBER GOOD ENGINE ON THE WIND SIDE.
Vmu REPRESENTS WHAT SPEED
MINIMUM SPEED TO GET AIRBORNE WITH 1 ENGINE INOPERATIVE
MAXIMUM UPDRAFT CAPABILITY SPEED LIMIT
MINIMUM SPEED TO GET AIRBORNE WITH ALL ENGINES OPERATING
MAXIMUM SPEED FOR MANUEVERING
MINIMUM SPEED TO GET AIRBORNE WITH ALL ENGINES OPERATING
To increase altitude while flying at an angle of attack greater than CLmax you should:
Increase pitch.
Increase thrust.
Extend the flaps since this is the only way to increase more lift beyond CLmax
It is not possible to climb at angles of attack beyond CLmax.
Increase thrust.
You are on an ILS approach to runway 33. Your aircraft’s VREF speed is 144 knots. The winds are 280 at 15 knots. Your Approach category is:
Category A
Category B
Category C
Category D
Category D
When an aircraft tends to return to its original attitude of equilibrium it has?
Neutral static stability.
Dynamic static stability.
Positive Static Stability.
Positive Static Stability.
For a given weight airplane, the angle of climb depends on the difference between thrust and
Available airspeed.
Drag.
Weight.
Power.
Drag.
What is True Airspeed?
Airspeed corrected for position error.
Actual speed of aircraft through the air corrected for density altitude.
Airspeed corrected for wind.
Actual speed of aircraft through the air corrected for density altitude.
If an airplane is incorrectly loaded with an aft C.G., which handling characteristics may you expect on takeoff?
Longitudinal instability, greater control input for pitch control.
More back force is required during rotation.
No changes in rotation is required due to no adverse effects.
Less back force is required during rotation
Less back force is required during rotation
Yaw – Roll crossover speed is best defined as:
The AOA sensitive speed at which roll produced by sideslip cannot overcome roll produced by ailerons and spoilers.
The AOA sensitive speed at which roll produced by aileron and spoilers cannot overcome roll produced by sideslip.
The speed at which an aileron induced roll results in proverse yaw.
The speed at which a sideslip induced roll results in adverse roll.
The AOA sensitive speed at which roll produced by aileron and spoilers cannot overcome roll produced by sideslip.
An aircraft that returns to its original trimmed condition after being displaced would be:
Statically stable
Statically unstable
Dynamically unstable
Dynamically stable
Dynamically stable
What effect does an increase in altitude have on stall speed?
Stall speed will increase slightly.
Stall speed will decrease slightly.
Stall speed will decrease dramatically due to compressibility effects.
Stall speed will increase dramatically due to compressibility effects.
Stall speed will decrease dramatically due to compressibility effects.
