Command Interview Tech.

Question 1

When does the NGS unit automatically shutdown?

Answer 1

• either engine not running in flight
• aircraft on ground and not in test mode
• Fire or smoke detection in cargo or main deck areas
• left pack o/h
• centre tanks refuelling valve is open.

Question 2

How does the landing gear transfer unit work?

Answer 2

Hyd system B pump supplies volume of fluid need to operate the landing gear transfer unit when all of the following conditions are met:

• airborne
• No1 engine rpm drops below a limit value
• landing gear lever is positioned up
• either main gear is not up and locked.

Question 3

RNP values oceanic, star and app?

Answer 3

4. 0
5. 0
6. 0
7. 3 or less.

Question 4

How long does the isfd last for?

Can you do an app at the end?

Answer 4

Isfd itself lasts for 150mins but plus 30mins on battery =180mins
No app as there Is no ILS.

Question 5

If rated thrust is required for t/o when are you required to recalculate performance?

Answer 5

Any Change in environmental conditions

Question 6

X/wind wet rwy?

What about when using asymmetrical reverse thrust?

Answer 6

25kts

20kts

Question 7

When does the standby yaw damper work?

Answer 7

Manual reversion, both flt control switches must be in standby rudder and YD switch on.

Question 8

The RF formthe hydraulic quantity comes on when?

What reqmnts must be met for it to come on?

Answer 8

76%

Valid only when a/c is on ground with both engines shutdown or after landing with flaps up during taxi in?

Question 9

What a re the start limits for starting 1 engine inflight?

What time frame do you abort the start?

Answer 9

725’c

No increase in eft by 30secs or another abort start scenario.

Question 10

Is “windshear ahead wx radar or gpws generated?

Answer 10

Wx radar.

Question 11

Reqmnts to de-ice for csff?

Answer 11

No requirement to de-ice if

• temp 4’c or greater,
• no precipitation or fog with vis below 1600m
• no ice on leading edge or control surfaces
• fuel temp not below -16’c.

If any of the above criteria are not met then allowed up to 3mm on lower surface.

Question 12

When can you have csff on top of wing?

Answer 12

Only within lines on top of wing,
No precipitation,
OAT 4’c or above
Fuel temp is at or above -16’c

If all of the above are not met de-ice.

Question 13

Speed control on final until what on visual app and instrument app?

Answer 13

4nm

5nm

Question 14

Separation in class c airspace?

Answer 14

Ifr from ifr and vfr and svfr

Question 15

Separation class d airspace?

Answer 15

Ifr from ifr and svfr.

Only traffic info on vfr.

Question 16

GPWS input?

Answer 16

Stall management computer
FMC, IRS, ILS, radio altimeter,
Efis control panel
Adiru

Question 17

RVSM reqd equipment?

Answer 17

Two independent altimeters,
Autopilot
Altitude alerter
Mode C transponder

Question 18

What/when happens with on app logic?

Answer 18

Either within 2nm of 1st app waypoint or 2000ft of airport elevation whichever occurs first.

Enables,
Unable RNP levels are higher
As long as alt alerter is at least 300ft above a/c will keep descending.
If a/c is more than 200ft below path will command level fight to regain path.
If mcp alt is more than 250ft above current alt vnav remains in vnav path.

Question 19

Go around logic occurs when?

Enables what?

Answer 19

Below 2000ft if any of following occur:

• Toga pushed,
• Direct to a waypoint in the missed app
• Crossing the 1st missed app waypoint
• a climb of 600fpm or more and flaps retracted from landing flap to either 15 or 1.

Enables:

• Changes from active descent to active climb
• go around thrust limit
• all alt constraints below a/c deleted replaced by advisory alts
• original destination become departure airport so Sid can be entered.
