Define MINTO
Min fuel at start of takeoff roll.
Enough to go to destination / shoot approach / go to furthest alt/ then fly 45 min.
What is release fuel
MINTO + taxi-out + contingency
What is contingency fuel
Calculated from 10,000 feet above destination airport. Basically extra gas for random stuff like possible wx, delays, etc.
What are the requirements for filing a takeoff alternate.
If wx below landing minimums at takeoff airport you need one.
Within 1 hour
Normal cruise speed
Still air
1 engine inop
Requirements for Alternate
Always unless 1 2 3
1 hour before to 1 hour after ETA
Ceiling below 2000. OR
Visibility below 3 miles
Where is TOC on release
Separate fix on flight plan page
What is required at TOC
Compare TOC fuel on release and compare to fuel onboard.
Check landing fuel
Where is tropopause on release
Why is it good to know where it is
On flight planning pages by MWL
Good to know because most weather is below that altitude
What are the sabre wind shear values
They are determined by looking at changes in wind speed 4000 feet below the segment altitude.
Describe cost index vs flight release planning
Ratio between:
Cost of TIME vs cost of FUEL
Idea is to find the perfect balance between TIME AND FUEL
Slower than Costindex= less fuel but more time.
.When is a runway considered contaminated?
4 things
When 25% of runway surface (whether isolated or not) within required length is
- Water more than 3mm
- Slush or snow more than 3mm
- Snow compressed together
- Ice
When is a drift down alternate required?
If there are obstacles that you wouldn’t be able to clear if you lost an engine.
Method 1 drift down.
- Assumes engine failure at?
- Gives __________foot terrain separation within______
- At destination must be able to have positive rate of climb to __________?
- V1
- 1000’ within 5 miles of route
- 1500’
Method 2 drift down
- Engine failure _________
- Gives __________ feet terrain separation within_________
- Positive rate of climb up to __________
- After V1
- 2000’ within 5 miles of intended route
- 1500’
Drift down alt must be within__________
Runway must meet ___________ and ____________
Requirements,
- 130 miles
2. Length and runway condition.
