1a Flashcards
2-B Describe the function of the AHRS
To provide attitude , heading, rate of turn, and slip/skid information, integrated flight displays use an attitude and heading reference system (AHRS). AHRS uses inertial sensors such as electronic gyroscopes and accelerometers to determine the aircraft’s attitude relative ti the horizon. An electronic magnetometer provides magnetic heading data.
2-B The true statement regarding the digital attitude indicator is
In a slip, the trapezoid fo the slip/skid indicator located beneath the roll pointer moves the inside of the turn.
2-B What information is provided by the trend vector on the HSI?
The trend end of the trend vectorshows what the airplane’s heading will be in six seconds if the turn continues at the same rate, Index marks 18 degrees either side of center on the turn rate indicator provide a reference for standard rate turns.
2-B if the AHRS detects a problem with the integrity of the sensor information, what occurs?
A red X is placed over the display of the affected instrument(attitude indicator or HIS).
2-B A true statement about the ADC
The pitot tube, static source, and outside air temperature probe provide information to the ADC.
2-B What is true about the indications on the altimeter?
The trend indicator shows where the plane will be in six seconds.
2-B Describe how the electronic flight display compensates for a screen failure of the PFD.
The integrated flight display is configured so that the functions of the PFD can be transferred to the MFD screen and vice versa. If the PFD screen turns black, the PFD display should automatically switch to the MFD in reversionary mode. In the event that the PFD does not appear on the MFD most systems enable yo to manually switdh to reversionary mode.
2-B An enhanced flight vision system (EFVS)can be displayed on a PFD.
FALSE
2-B Describe at least three functions of a typical MFD.
*Moving Map Display, show data, your position, route of flighttopography, terrain proximity, weather and traffic. * Waypoint, find airport, runways, navaids, IFR info/charts. *Aux display settings, verify GPS,checklists, planning. * Nearest if need to divert, obtain airports, navaids, ARTCC, FSS, airspace info
2-B Select the true statement regarding autopilot operation.
After engaging the autopilot, you should verify that the selected modes appear on the annunciator panel.
2-A What flight instruments are required for flight under IFR?
All VFR, Gyroscopic rate of turn indicator, slip-skid , sensitive altimeter adjustable for barometric pressure, Clock with seconds, gyroscopic pitch and bank (artificial horizon), gyroscopic direction
2-A Name the gyroscopic flight instruments. What are the two principles that are characteristic of all gyroscopes?
Attitude indicator, heading , turn coordinator. Two Principles: rigidity in space and precession
2-A Which flight instruments gives you an instantaneous display of both pitch and bank information?
attitude indicator.
2-A The gyroscopic instrument are the only flight instruments that provide bank information.
TRUE
2-A Why is the turn coordinator a good back up for the attitude and heading indicators in most small airplanes?
Turn coordinator is electric, attitude and heading indicators are vacuum. Either fails still have turn information.
2-Awhat is the approximate bank angle required to maintain a standard rate turn at 90 knots?
14 degrees
2-A How long soes it that to make a 360 standard rate turn?
two minutes
2-A Which turn coordinator shows too much rudder pressurebeing used for the amount of bank?
2-28
2-A Which turn coordinator shows too little rudder pressure being used for the amount of bank?
2-28
2-A What conditions leads to unreliable operation of the heading indicatior and attitude indicator?
Low vacuum
2-A What should you use to correct for magnetic deviation?
Compass correction card
2-A During a compass turn, what heading should you use for roll-out if making a right turn to a heading of 360 at a latitude of 45 North? Assume you are using 16 bank angle.
12 degrees
2-A V speeds are Va is? Vlo is? Vs1 is?
Va = Design manuevering, Vlo = Max landing gear operating, Vs1 Stall speed in specified configuration
2-A Define these terms: indicated altitude, pressure altitude, density altitude and true altitude.
indicated altitude = is altitude read from altimeter set to current. pressure altitude = Reading when altimeter is set to 29.92. density = pressure altitude corrected for non-standard temperature. true altitude = is actual height above mean sea level
