Q

How many sensors are part of the ADIRS?

A
‐ Four types of sensors: 
• Pitot probes (3) 
• Static pressure probes (STAT) (6) 
• Angle of attack sensors (AOA) (3) 
• Total air temperature probes (TAT) (2)
2
Q

Meaning of amber IR FAULT light

A

Steady: the respective IR is lost
Flashing: the attitude and heading information may be recovered in ATT mode.

3
Q

Full Scale Deflection on ND

A

VOR: Full-scale deflection is 10°/ 1 dot = 2° of dev.
ILS approach: Full-scale deflection is 2½°/ 1 dot = ½°of dev.
RNAV (5 dot CDI): FSD = 5NM displacement from selected course
Glide Slope scale: FSD = about 0.5-0.7° of deviation.

  • Crew stored information
5
Q

Components of an ILS

A
  • localizer
  • glide path
  • marker beacons
  • approach lights
6
Q

Benefits of RNAV

A
  • allows aircraft to fly more direct routes
  • no longer need to fly over ground based nav
  • allows for reduced vertical and horizontal separation
