Supplementary Procedures - PRO-SUP-70 Power Plant

Question 1

051- What is Specific about MANUAL Thrust and the Various Detent Positions of the Thrust Levers (TLV)?

PRO-SUP-70 P3

Answer 1

• If One or Both Thrust Levers are Short of CL Detent,

the ENG Inst. Display Shows:

CL Continuously

• If One or Both Thrust Levers are Above CL Detent,

it Shows:

MCT/FLEX

• If One or Both Thrust Levers are Above MCT Detent,

it Shows:

TOGA

• With the Thrust Levers Positioned in a Specific Detent,

the ENG are Limited to that Detent Parameters.

Question 2

052- How Autothrust Disconnection may Occurs?

PRO-SUP-70 P4

Answer 2

• Abnormal way:

* If The A/THR Fails

* If Both Thrust Levers are Set to IDLE

• Standard way:

* Via the Thrust Levers Instinctive Disconnect Button

* Via the FCU’s A/THR Pb (NOT Recommended).

Question 3

053- Who Should Perform the Manual Start?

PRO-SUP-70 P6

Answer 3

The PF (Procedure Read by the PM)

It’s No Longer a Cpt Only Procedure.

Question 4

054- When a Manual ENG Start is Recommended?

PRO-SUP-70 P6

Answer 4

After Aborting a Start due to:

• Engine Stall
• Engine EGT Over Limit
• LO START AIR PRESS
• No N1 Rotation
• Hung Start

When Expecting a Start to Abort due to:

• Low Bleed Performance Expected because of:

* Hot Weather Conditions

* High Altitude Airfield

* External HP Air Supply

• Tailwind > 10 Kt.

Question 5

055- What are the Alternatives to Standard Start / Shutdown Procedures?

PRO-SUP-70 P7-12

Answer 5

For Start:

• Manual Engine Start Procedure (p 7)
• Engine Start With External Pneumatic Power (p 9)
• Cross Bleed Engine Start (p 10)
• Start Valve Manual Operation (p 11)

For Start/Cruise:

• Detection of Handling Bleed Valve Malfunction

PRO-SUP-70 P 12

For Shutdown:

• NO ENG Shutdown After Setting ENG Master Sw To OFF.

PRO-SUP-70 P 12

Question 6

056- How to Detect a Handling Bleed Valve Malfunction?

PRO-SUP-70 P12

Answer 6

• Starting difficulties:

* ENG Hung start

* ENG Sub-Idle Stall / ENG Roll Back

* ENG Start EGT Exceedance

• TakeOff EGT Higher than:

* Typical ENG-to-ENG Variations

* Typical ENG EGT Margins

• Fuel Flow: (Cross-Wing Comparison)

* > +3 % in Cruise

* > +6 % in Climb / Alternate / Diversion Conditions

• Climb / Cruise EGT Shift: (Cross-Wing Comparison)

* +20° C to +50° C

• Engine Stall (Surge) upon:

* Engine Transient (Acceleration or Deceleration)

In this Particular Case a Maintenance Action is due

Prior to the Next Flight.

Question 7

057- What are the N2 and Temperature Limitations for a Manual ENG Start?

PRO-SUP-70 P8

Answer 7

Do NOT Attempt Manual ENG Start Unless:

• N2 is at Least 15 %
• EGT has Dropped to the Minimum Achievable.

* Beware of Starter Motoring Time Limitation (4 Min)

Beginning with the ENG START.

Question 8

058- During a Manual ENG Start, What to do if there is a Sudden Electrical Power Supply Interruption?

PRO-SUP-70 P9

Answer 8

It will be Noticed by the Loss of ECAM displays

• Immediately Abort Start by Setting ENG MASTER to OFF
• Then Perform a 30 Sec Dry Crank.

Question 9

059- What the Correlation between EGT Temp and N2?

PRO-SUP-70 P12

Answer 9

• If EGT Increase due to Engine Deterioration:

* N2 Decrease

• If EGT Increase due to Handling Bleed Malfunction:

* N2 Increase.

Question 10

060- How to Detect a Handling Bleed Valve Malfunction?

PRO-SUP-70 P12

Answer 10

Question 11

061- What to do if On Ground there is NO ENG Shutdown after setting ENG Master Sw to OFF?

PRO-SUP-70 P 12

Answer 11

• ECAM FUEL Page — PRESS
• LP FUEL Valve Position (Affected) — CHECK

* If LP Fuel Valve is Closed - (Cross Line in Amber)

No Crew Action are Required

* If LP Fuel Valve is Not Closed

ENG FIRE Pb Sw (Affected) — PRESS

Please Note:

The Shutdown of the ENG can Take Up to 2’30”.
