QUIZ-Aircraft Navigation Sys

Which instrument will become inoperative if the pitot tube becomes clogged?

• ADI
• ALT
• ASI
• VSI

What could most likely cause the sudden drop in airspeed readings from the ADC?

• Pitot tube blockage
• ADC sensor input failure or data corruption
• Airspeed indicator malfunction
• Static port obstruction

The position error of an Airspeed Indicator will reach its maximum value when

• Diving speed.
• Cruising speed.
• Flying at low angle of attack
• Flying at high angle of attack

When an aircraft altimeter is set at 29.92" Hg on the ground, the altimeter will read

• Pressure altitude
• Density altitude
• Field elevation
• Gage altitude

When aircraft descend, the pressure inside the diaphragm of Rate of Climb Indicator

• The same with cabin pressure
• Less than instrument case pressure
• Higher than instrument case pressure
• The same with instrument case pressure

Left horizon bar of Attitude Indicator move down, this mean the aircraft is

• Climbing
• Descending
• Left banking
• Right banking

When flags such as NAV, HDG, or GS are displayed on EHSI, the indication is

• That function is normal operating
• That function is inoperative
• To give warning that any displacement of instrument part.
• To call attention to deviation from the desired setting, or flight path, or heading, etc

The function of a Symbol Generator (SG) or Display Management Computer (DMC) in an EFIS is to

• Display alphanumeric data and aircraft representation
• Generate electrical signal from gyro system
• Allow the pilot to select the system configuration.
• Receive and process input signal from aircraft sensor

What is the most likely reason for the crew needing to activate the ISFD?

• Complete failure of the primary flight display (PFD) system
• Electrical failure affecting only the autopilot system
• Pitot-static system malfunction
• GPS failure

Electronic Centralised Aircraft Monitoring System (ECAM) operates to

• Performs in-flight and ground tests of aircraft systems by carrying out a BITE interrogation
• Display attitude and direction or heading of aircraft
• Give red warnings and amber cautions to display system status.
• Give local warnings and amber cautions to display system status.
