Instrumentation

難易度: High試験の重み: Medium

概要

Instrumentation covers all aircraft instruments and electronic systems. This includes pitot-static instruments (airspeed, altimeter, VSI), gyroscopic instruments (attitude, heading, turn coordinator), magnetic compasses, electronic flight displays (EFIS, glass cockpits), engine instruments, and warning/recording systems.

主要トピック

Pitot-static system and instruments
Altimeter errors and settings (QNH, QFE, QNE)
Airspeed indicator markings and limitations
Gyroscopic instruments and precession
Magnetic compass errors (ANDS/UNOS)
Electronic Flight Instrument Systems (EFIS)
Flight Management Systems (FMS)
Engine monitoring instruments
Warning and alerting systems (GPWS, TCAS)
Flight Data Recorder and CVR requirements

学習のヒント

Learn the physics behind each instrument — understanding why it works reveals why it fails

Master compass errors (variation, deviation, dip, acceleration, turning errors)

Practice altimetry calculations with different QNH/QFE/QNE settings

Understand the difference between indicated, calibrated, equivalent, and true airspeed

Study gyroscopic precession to understand attitude indicator and DG errors
