Study Notes
JAR-25 Colour Code Rules for EFIS
- Turbulence is displayed in white or magenta.
- Engaged modes are indicated in green on an EFIS.
- A selected heading is highlighted in magenta.
- The selected heading in JAR OPS is shown in magenta.
- Features displayed in cyan/blue represent the sky.
- Increasing intensity of precipitation is indicated as: green, amber/yellow, red, magenta.
- Current data and values appear in white.
JAR OPS Colour Recommendations
- Armed AFCS (Automatic Flight Control System) modes are represented in white.
- The active route is marked in magenta.
- Downpath waypoints are shown in white.
Navigation Techniques
- RNAV (Area Navigation) allows operation on any flight path within coverage of station-referenced aids or within limits of self-contained aids.
- Basic RNAV demands track-keeping accuracy of ±5 NM for 95% of flight time.
- Precision RNAV (P-RNAV) requires accuracy of ±1.0 NM for 95% of flight time.
Radio Wave and Frequency
- Attenuation of a radio wave refers to the reduction of its power due to absorption, scattering, or spreading.
- VHF band operates within the range of 30 – 300 MHz.
Radar Systems and Range
- To enhance the theoretical maximum range of a pulse radar system, reduce the Pulse Repetition Frequency (PRF) and increase power.
Accuracy and System Reference in RNAV
- A DME/DME configuration provides the best accuracy in an RNAV system.
- The accepted accuracy for P-RNAV is 1 NM.
- A 5-dot HSI in RNAV approach mode corresponds to 0.25 NM per dot.
- The most accurate RNAV position is achieved using Rho/Rho external references.
