| Question | Answer |
|---|---|

| What are the standard temperature and pressure values for sea level? | 15 degrees C, 29.92" Hg |
| The forced landing final approach airspeed with flaps T/O is ___ KIAS | 60 |
| Which of the following will decrease the landing roll distance? | Low humidity |
| The maximum crosswind component for student landings during a dual flight is ___ knots. | 15 |
| Under which condition will pressure altitude be equal to true altitude? | When standard atmospheric conditions exist. |
| What effect will a tailwind have on published landing ground roll distances? | increase |
| If the outside air temperature (OAT at a given altitude is warmer than standard, the density altitude is | higher than pressure altitude. |
| What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why? | Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes. |

| Which items are included in the empty weight of an aircraft? | Unusable fuel and undrainable oil |
| Under which condition is a forward CG most critical? | On landing. |
| What is the definition of Vfe? | The maximum Flap Extended speed. |
| What is the purpose of the yellow arc on the airspeed indicator? | Indicates the airspeed range which may be utilized only in smooth air, and then only with caution. |
| What effect will an aft center of gravity )within the Weight & Balance envelope) have on airspeed? | An aft center of gravity will allow for a faster airspeed. |
| High air temperature will have all of the following effects on aircraft performance except | increased engine power output. |
| Which statement is true regarding takeoff performance with high density altitude conditions? | The acceleration rate is slower because the engine and propeller efficiency is reduced. |
| What effect does high density altitude have on aircraft performance? | It reduces climb performance. |
| Takeoff performance iwll decrease, resulting in a longer takeoff roll, for all of the following except | increasing barometric pressure. |
| After takeoff, which airspeed would the pilot use to gain the most altitude in a given period of time? | Vy |
| What effect, if any, does high humidity have on aircraft performance? | It decreases performance. |
| With the flaps in the CRUISE position, the positive and negative G limits for the DA20-C1 are ___ and ___. | +4.4, -2.2 |

| Which would provide the greatest gain in altitude in the shortest distance during climb after takeoff? | Vx |
| What is pressure altitude? | The altitude indicated when the barometric pressure scale in the Kollsman window is set to 29.92" Hg |
| If the CG of an aircraft is moved from the aft limit to the forward limit, how will it affect the cruising and stalling speed? | Decrease the cruising speed and increase the stalling speed. |
| An aircraft is loaded 110 pounds over maximum certicated gross weight. If fuel (aviation gasoline) is drained to bring the aircraft weight within limits, how much fuel should be drained? | 18.4 gallons. |
| Vso is defined as the | stalling speed or minimum steady flight speed in the landing configuration |
| Select the statement that is not correct concerning Maneuvering Speed (Va) | Va is the maximum indicated airspeed allowable when flying through rough air. |
| Vx represents what speed? | The best angle of climb airspeed. |
| If the atmospheric pressure and temperature remain the same, how would an increase in humidity affect takeoff performance? | Longer takeoff distance; the air is less dense. |
| An aircraft is loaded with the CG at the aft limit. What are the performance characteristics compared with the CG at the forward limit? | The aft CG provides the lowest stalling speed, the highest cruising speed, and least stability. |
| Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance? | High temperature, high relative humidity, and high density altitude. |
| What can a pilot expect with landing at an airport located in the mountains? | Higher true airspeed and longer landing distance. |
| Aircraft will not launch when the surface DA exceeds ____ feet. | 10,000 |
| Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates | true altitude at field elevation. |

| ___ is the difference between takeoff weight and empty weight. | Useful load |
| Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance? | High temperature, high relative humidity, and high density altitude. |
| Density altitude increases with | increases in temperature and moisture content of the air, and a decrease in pressure. |
| An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit. One undesirable flight characteristic a pilot might experience with this airplane would be | difficulty in recovering from a stalled condition. |
| Loading an airplane to the most aft CG will cause the airplane to be | less stable at all speeds. |
