Crosswind limitations Wet/Contaminated

A

Braking Action Runway Condition Takeoff Landing

Good Wet 25 20*
Good to Med Snow -No Melting 25 20***
Med to Poor Slush/St water 15 15
MED to Poor Ice Prohibited
Poor to Nil - Prohibited

Reduce crosswind limits by 5kts on wet and contaminated runways when landing single engine

** operations only allowed on UNTREATED snow when no melting is present

*** sideslip only landings are RECOMMENDED with crosswind component in excess of 17kts at flaps 15 (This ensure adequate ground clearance)

Q

Before commencing take off

A

OMA 8.1.3.9

The commander shall NOT commence take off unless the weather conditions are equal to or better than landing minima UNLESS a suitable take off alternate is available

When reported visibility is below that required and RVR is not reported the Initial part of takeoff run can be replaced by pilot assessment

When NO visibility or RVR is reported the Initial part of takeoff run can be replaced by pilot assessment

Q

Planning minima for Escape route aerodrome

A

OMA 8.1.3.12(D)

1 hour before to 1 hour after ETA the weather is at or above aerodrome operating minima

In flight segments where 2 escape routes aerodromes are indicated, flights can be dispatched if only 1 en-route aerodrome with weather at or above AOM

17
Q

ETOPS planning minima, when do planning minimums apply

A

OMA 8.1.3.12(E)

from expected time of arrival to 1 hour after the weather is at or above:

Precision approach: +200’ and +800m
Non Precession approach: +400’ and 1600m

SOM 2-5
planning minima applies until point of dispatch, when the aircraft first moves under its own power for the purpose of takeoff

SOM 2-16
After entry in ETOPS if weather falls below landing minima, continue on ETOPS flight plan route
