PERFORMANCE PENALTIES

Question 1

CONTAMINATED RUNWAY

Answer 1

V1 reductions from performance manual

No reduced thrust for takeoff slush/snow/ice or standing water greater than 3mm

Question 2

Slush Snow Standing water greater than 13mm

Dry Snow greater than 102mm

Answer 2

DO NOT TAKE OFF

Question 2

One Reverser Inoperative

Answer 2

TAKEOFF NOT PERMITTED ON A CONTAMINATED RUNWAY WITH ONE REVERSER INOPERATIVE.
To Find Adjusted Wet Takeoff Limit Weight
Apply the wet runway correction of 3000 kg to obtain the wet runway takeoff limit weight.
Further reduce the wet runway takeoff limit weight obtained by 3500 kg.
Apply the wet runway correction of 8kt to obtain the wet runway takeoff V1. Further reduce the wet runway takeoff V1 by V1 reduction given in the table

Question 3

Automatic Landing field length increment

,

Answer 3

Automatic Landing

Add 15% to the Landing Field Length obtained from “Landing Field Length” charts,

Question 4

Auto Spoiler If it is inoperative and manual spoiler is used,

Answer 4

Auto Spoiler
, increase chart field length by 250m (or reduce available length by 250m to determine Limit Landing Weight), when using Flap
25 or 30.

Question 5

Full Reverse Thrust

. If reverse is unavailable on one engine the chart limit?

Answer 5

Full Reverse Thrust
Full reverse thrust is normally expected to be available. If reverse is unavailable on one engine the chart limit field
length must be increased by 120m (or available field length reduced by 120 m to determine Limit Landing
Weight).

Question 6

Idle Reverse Thrust

the field length should be increased by

Answer 6

Idle Reverse Thrust
At designated locations there is a requirement for operating with no more than idle reverse thrust. In this case the
factored landing length increases by 300m on wet runways and 100m on dry runways. Therefore when dispatching
with the intent of using not more than idle reverse thrust, the field length should be conservatively increased by
300m.
