Performance Flashcards
Where does a diversion begin when using a drift down alternate?
Method 2.
Divert begins when abeam the airport listed.
The listed suitable airport should be no more than 130nm from the abeam point.
How is performance affected on a DRY runway?
Field length X 0.8
How is performance affected in a WET runway?
Field length X 0.9
How is performance affected on a CONTAMINATED runway?
Field length X 1.15
What is the relevance of ground vehicle friction readings?
Reported by ATIS in mu. mu does not directly correlate to the actual performance experienced by the aircraft. >50 excellent 35-50 good 26-35 fair
What are the single engine bank limitations?
V2 = 15* V2+5 = 20* V2+10 = 25*
What altitude can a crew deviate a STANDARD takeoff and proceed on course?
No turns below 1000’ when the WX is less than 3sm and 1000’
FRA is 1000’
What are the special takeoff procedures?
Simple special and Complex special.
These are used when obstacles exist that prevent a standard takeoff profile when an engine fails.
Define a standard engine failure procedure.
Start turn at 1000’ AFE
Turn to HDG or Nav Aid
in VMC, you can deviate above 1000’
Define a Simple-Special Engine Failure Procedure
Requires a turn to a NavAid before reaching 1000’. HDG can start @ 50’.
FRA remains 1000’.
Mandatory in IMC.
Mandatory in VMC until 1000’.
If vectors are unavailable in IMC, Comply until 3000’ then proceed on course.
Define a Complex-Special engine failure procedure
issued when a profile is too complex for the simple special table.
FRA is 1000’ unless noted.
may be designed for a specific departure procedure.
Mandatory in both IMC and VMC!!!
What if you experience and engine failure and no procedure is provided?
IMC-
climb straight ahead until 1000’, turn using max bank angle for speed direct to navaid, hold standard on inbound leg until MSA. Radar vectors can be accepted above 1000’.
VMC-
climb straight ahead to 1000’ return to land visually and complete IMC procedure.
What bank angle is used when executing a standard special when turning to a navaid or heading?
Maximum bank angle appropriate for the aircraft speed.
When is a runway considered CONTAMINATED?
When more than 25% of the runway surface area is covered by more than 1/8” (3mm) of standing water, or its equivalent in slush, wet or dry snow.
When is a runway considered WET?
When it has a shiny appearance due to a thin layer of water 1/8” (3mm) thick covering 100% of the runway surface. If there are any DRY spots with no standing water, the runway is NOT wet.
