17 787 Performance

Question 1

Define the Take-Off Performance Limit (TOPL) Weight.

Answer 1

The maximum permissible take-off weight at which the aircraft can attain the regulated performance requirements.

Question 2

The MEL performance corrections for operations with degraded/missing equipment is normally applied to which aircraft weight?

Answer 2

TOPL.

Question 3

What aircraft weight meets both the regulated performance requirements and the operators chosen certification?

Answer 3

Regulated Take-Off Weight (RTOW).

Question 4

The OPT can be used in the pre-flight planning stage to calculate the Maximum Landing Weight permitted at an airfield. Weights and allowable tailwinds can be planned: -

a. For which flap settings?
b. ForbothManualandAutomaticlandings?
c. What is the assumption regarding braking for dry or wet conditions? d. Whataboutslipperyconditions?

Answer 4

a. Flap 25 & 30
b. Yes
c. The use of maximum wheel brakes and no reverse thrust for normal
landings.
d. Full reverse thrust on all engines.

Question 5

Which OPT application should be used to check the landing performance prior to arrival to ensure the runway is suitable for the intended landing?

Answer 5

OPT En-route Landing Calculation.

Question 6

Under what conditions should FULL reverse thrust be used on landing?

Answer 6

1. The runway is covered by standing water, snow, slush or ice.
2. The Target Threshold Speed has been increased for a deficiency.
3. There is any unserviceability of speed brakes, wheel brakes or anti-skid.

Question 7

When is a runway defined as being wet?

Answer 7

Having less than 3 mm of water on the surface and a friction co-efficient of approximately one half of that of a dry runway but with ‘braking action good’.

Question 8

a. Where can an airfield’s RIM category and ILS Status be found in the OPT Landing Performance application?
b. What other airfield information is found on this page?

Answer 8

a. UndertheARPTCOMMENTsoftkeyonthePERFORMANCE- AIRPORT DATA (see also Chapter 6: Reviewing Airport Data).
b. The Missed Approach Acceleration Altitude (MAAA) or equivalent, and any landing notes for all available runways (see Chapter 6: Reviewing Airport Data).


Question 9

What does the ILS Runway Status Code ‘E’ mean?

P&OI

Answer 9

Runway is suitable for AUTOLAND evaluation.

Question 10

Which Approach Climb GRADIENT option should be selected on the OPT Landing Page for a CAT I approach?

Answer 10

IGNORE GRADIENT. (This applies the regulatory limit of 2.1%)

Question 11

In the event the aircraft systems capability is downgraded to CAT IIIA and only CAT IIIB minima is published on the LIDO approach plate, which minima should be used?

Answer 11

CAT IIIA DH 50R/RVR 200 m.

Question 12

What must be the Runway ILS Status be for an ‘ILS or GLS C1’ approach?

Answer 12

‘B’, ‘E’ or ‘LR’.
