| Question | Answer |
|---|---|
| which v speed represent maneuvering speed? | Va |
| if an altimeter setting is not available before flight, to which altitude should the pilot adjust the altimeter | the elevation of the departure. |
| Prior to take off, the altimeter should be set to which altitude or altimeter setting? | the current local altimeter setting, if available, or the departure airport elevation |
| if the pitot tube and outside static vents become clogged, which instrument s would be affected? | the altimeter, airspeed indicator, and vertical speed. |
| which instrument will become inoperative if the pitot tube becomes clogged? | airspeed. |
| which instrument(s) will become inoperative if the static vents become clogged? | airspeed, altimeter, and vertical speed |
| 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. |
| what is true altitude? | is the vertical distance of the aircraft above sea level. |
| what is absolute altitude? | the vertical distance of the aircraft above the surface. |
| what is absolute altitude? | the vertical distance of the aircraft above the surface. |
| what is density altitude? | is the pressure altitude corrected for nonstandard temperature. |
| what is pressure altitude? | the altitude indicated when the barometric pressure scale is set to 29.92 |
| under what condition is indicated altitude the same as true altitude? | when at sea level under standard condition |
| if it is necessary to set the altimeter from 29.15 to 29.85, what change occurs? | 700 foot increase in indicated altitude. |
| the pitot system provides impact pressure for which instrument? | airspeed indicator. |
| as altitude increase, the indicated airspeed at which a given airplane stalls in particular configuration will | remain the same regardless of altitude. |
| what does the red line on an airspeed indicator represent? | Never exceed speed |
| what is an important airspeed limitation that is not color coded on airspeed indicators? | Maneuvering speed. |
| a turn coordinator provides an indication of the | movement of the aircraft about the yaw and roll axes |
| To receive accurate indications during flight from a heading indicator, the instrument must be | periodically realigned with the magnegtic compass as the gyro precesses |
| the proper adjustment to make on the altitude indicator during level flight is to align the | miniature airplane to the horizon bar |
| how should the pilot determine the direction of bank from an attitude indicator | by relationship of the miniature airplane to the deflected horizon bar |
| Deviation in a magnetic compass is caused by | magnetic fields within the aircraft distorting the lines of magnetic force |
| in the northern hemisphere, a magnetic compass will normally indicate initially a trun toward the west if | right turn is entered from a north heading |
| in the northern hemisphere, a magnetic compass will normally indicate initially a turn toward the east if | left turn is entered from a north heading |
| in the northern hemisphere, a magnetic compass will normally indicate a turn toward the north if | an aircraft is accelerated while on an east or west heading. |
| In the norther hemisphere, the magnetic compass will normally indicate a turn toward the south when | the aircraft is decelerated while on a west heading. |
| in the northern hemisphere, if an aircraft is accelerated or decelerated, the magnetic compass will normally indicate correctly | when heading south or north |
| during flight, when are the indications of a magnetic compass accurate | only straight and level unaccelerated flight |
| if the outside air temperature (OAT)at a given altitude if warmer than standard, the density altitude is | higher than pressure altitude. |
| what are the standard temperature and pressure values for sea level | 15C and 29.92 inches Hg |
| if a pilot changes the altimeter setting from 30.11 to 29.96, what is the approximate change in indication? | altimeter will indicate 150 feet lower |
| under which condition will pressure altitude be equal to true altitude | when standard atmospheric condition exist |
| under what condition is pressure altitude and density altitude the same value? | at standard temperature. |
| if a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted, the altimeter will indicate | lower than the actual altitude above sea level |
| if a flight is made from an area of high pressure into an area of lower pressure without the altimeter setting being adjusted, the altimeter will indicate? | higher than the actual altitude above sea level |
| under what condition will true altitude be lower than indicated altitude? | in colder than standard air temperature. |
| which condition would cause the altimeter to indicate a lower altitude than true altitude? | air temperature warmer than standard. |
| which factor would tend to increase the density altitude at a given airport? | an increase in ambient temperature. |
| the angular difference between true north and magnetic north is | magnetic variation |
| what should be the indication on the magnetic compass as you roll into a standard rate turn to the right from a south heading in the northern hemisphere | the compass will indicate a turn to the right, but at a faster rate than is actually occurring |
| when converting from true course to magnetic heading, pilot should | add westerly variation and subtract lef wind correction angle( east is least. west is best) |
