CBT - Performance

Question 1

RLD to ALD? and RLD dry to RLD wet

Dry

Answer 1

RLD= 1.67 ALD
ALD = 0.6 RLD
RLD wet= 1.15 RLD Dry

Assumes maximum braking at touchdown without reverse credit for dry rwy

Dispatch uses it to see if the regulatory increment with the actual landing conditions and weights complies with the rwy length at destination

Question 2

What are the different color of the fonts in the performance applications and what do they mean?

Answer 2

Question 3

What is the “MIN” GA Gradient for the A380?

And in CAT II/III

Answer 3

2.7%

2.5% for CAT II/III

Question 4

What are the limitation codes on the landing performance application?

Answer 4

Question 5

In landing performance, how is reverse thrust taken into account in “DISPATCH” and “IN-FLIGHT”?

Answer 5

• Dispatch: No reverse credit for Dry/Wet. Only for Contaminated
• In-Flight: Reverse thrust is taken into account for all RWY conditions

In case of dispatch with one rev inop. credit for the operative one is taken into account for contaminated rwys.

Question 6

What additional inputs can a pilot insert for the inflight landing performance calculation when compared to dispatch inputs?

Answer 6

Landing CG and BRK modes are added

Question 7

What is the relationshio between FLD and inflight landing distance?

Answer 7

FLD= 1.15 Inflight Landing Distance

May be disregarded in excpetional circumstances

Question 8

How are ECAM alerts and MEL/CDL items colour coded in the performance apps?

Answer 8

Question 9

In the loadsheet app, what does “CG targetting” and “trim adjustment” entail?

Answer 9

CG Targeting: Enables to visualize the predicted fuel distribution after refueling in accordance with teh FQMS CG Targeting logic
Trim Adjustment: When the crew is requested to set the trim tank fuel quantity as per the ECAM FUEl SD information

Question 10

What is the TMAX Flex for the A380?

Answer 10

ISA+60

TREF ISA+15

Question 11

What is the benefit of derated thrust?

Answer 11

Its reduces the overall engines thrust setting for takeoff as to reduce the VMCG thus reducing the V1 which will then require a shorter ASD.

Useful when the ASDA is limiting

Question 12

What are the main differences between derated and flex takeoff?

Answer 12

Derated T/O is allowed on contaminates rwy unlike with flex
TOGA is always available with flex but not with derated takeoff before F speed

Question 13

What are the descent types on the A380 inflight performance?

Answer 13

Question 14

What does OPT CONF for takeoff mean in TO Performance app?

Answer 14

Selects the config that gives the highest permissable T/O weight or max flex temp

Question 15

What are the limitation codes on the takeoff performance application?

Answer 15

Question 16

How is reverse credit taken into account foe takeoff performance

Answer 16

Dry: No Reversers
Wet/Contaminated: Reversers credited
