> 41kts

Question 28

When go-around is selected, what are parameters are captured?

Answer 28

1,000 ft/min climb, roll for wings-level and pitch for an airspeed of 80 KIAS or the current airspeed, whichever is higher. If below 70 kts it will engage a reference speed of 70 kts. LNAV will capture.

Question 29

When coupled with ILS APP or VGP, will the auto-level function work and what indication do you get on your PDF?

Answer 29

Yes, there will be an automatic flair at 50 RADALT initiated at 150', which will maintain that height. GS or VGP will change to ALVL. ALVL will not engage if the MAP is above 150 feet.

Answer 33

The data shows two elevation numbers that indicate the highest and lowest terrain currently being displayed, for example 150/85. The elevation numbers indicate terrain in hundreds of feet above MSL and are displayed with the highest terrain number first, and the lowest terrain number next.

Question 34

Answer 37

1. MODE 1 Excessive ROD SINK RATE 2. MODE 4 Unsafe terrain clearance TOO LOW TERRAIN 3. MODE 2 Excessive terrain closure rate terrain terrain

Question 38

Explain the PI limiting?

Answer 38

During collective coupled operation the collective movement is limited by the following Power Index (PI) values: * Maximum 97% AEO (reduced to 95% at altitudes above 10000 ft Hp) * Maximum 106% AEO for airspeed less than 60 KIAS (5 MIN message displayed beside collective cue) * Maximum 140% OEI * Minimum 5% AEO * Minimum 10% OEI When PI limiting function is active and is limiting maximum collective movement, an amber LIM caption is displayed beside the collective cue. If PI limiting is active with IAS engaged and the required reference for VS, ALTA, RHT, GA, or ALT cannot be achieved then the airspeed will automatically reduce as necessary to achieve the collective mode reference. If the collective mode reference cannot be maintained when the airspeed has reduced to a minimum of 80 KIAS, this airspeed will be maintained (IAS caption is displayed in green) and the collective mode reference will be reduced (the collective mode caption is displayed in amber). CAUTION IF PI LIMITING IS ACTIVE WITH ALT OR RHT ENGAGED AND THE REFERENCE BAROMETRIC ALTITUDE OR RADIO HEIGHT CANNOT BE MAINTAINED, THE AURAL WARNING “ALTITUDE – ALTITUDE” WILL WARN THE PILOT WHEN THE MAXIMUM ALLOWED DEVIATION FROM THE REFERENCE SETTING HAS BEEN EXCEEDED

Question 39

When does the CVR record?

Answer 39

The CVR starts recording upon power application to the FDR/CVR Unit from ESS 1 bus and stops within 10 minutes if the FDR non-recording condition persists. In a standard flight, the CVR starts recording as soon as the BATTERY MASTER switch is moved to ON and stops recording 10 minutes after the second engine is off after landing (Weight on Wheels).
