Instrument Stage 1 Exam 2024 with 100% correct answers

What percentage of all aviation accidents can be attributed to human actors-related causes? - correct answer Choice 3: 75% of aviation accidents can be attributed to human factors-related causes. Some sources of pilot error in the instrument and commercial environments include; misinterpretation of a chart, failure to understand a clearance, inability to use equipment properly, and lack of coordination among crew members. While enroute you read back a clearance to ATC and no response is recieved, you should assume - correct answer CHOICE 2 — Readback of ATC clearances is crucial in the IFR environment. You should not assume controller silence after a read back is verification of your transmission. If you are unsure if ATC understood your communication, ask for a verbal confirmation. A rapid acceleration during instrument flight can create the illusion of - correct answer CHOICE 3 — Your vestibular system is sending an incorrect message to your brain during a rapid acceleration, making you believe you are in a nose up attitude. The best way to overcome this is to rely on your instruments, since they are your only accurate source of information. During deceleration from cruise flight, precision error causes the attitude indicator to show a slight - correct answer CHOICE 3 — Acceleration or deceleration can induce precession errors within the attitude indicator. Deceleration causes the attitude indicator to give a temporary, false indication of a descent. How often should you check the heading indicator and align it with the magnetic compass? - correct answer CHOICE 1 — Due to internal friction within the gyroscope, precession is common to heading indicators. Precession causes the selected heading to drift from the set value. You should align the heading indicator with the magnetic compass before flight and check it at 15-minute intervals during flight. During an established coordinated turn at a constant airspeed and altitude, use the ailerons to control the rate of turn and the rudder to control the - correct answer CHOICE 3 — During a turn, the rudder controls the quality of the turn as indicated by the position of the ball in the inclinometer. If the ball is right of center, add right rudder pressure; if the ball is left of center, add left rudder pressure. The three pressure instruments connected to the pitot-static system are the - correct answer CHOICE 2 — The airspeed indicator, altimeter, and vertical speed indicator are the three pressure-sensitive pitot-static instruments. Each of these instruments is connected to a static source, however, only the airspeed indicator is conn
