Flashcards in Performance Deck (16):
When shall turns be normally initiated on a normal departure?
- NO turns shall be commenced below 1000' AFE when WX is less than 1,000 and 3sm vis
- Unless, Special DP prescribes otherwise
- ie. SID, ODP, SE DP
** Same w/flap retraction altitude
Do you have to follow the SE DP if you are VMC?
IMC: follow SE DP, or request radar vectors
VMC: Return to Land VISUALLY or complete IMC procedure (discretion)
- Typically follow SE DP for protection or request vectors immediately
What are the 3 types of Engine Failure Departure Procedures?
1. Simple: clm to 1000' AFE and turn to prescribed HDG or direct NavAid
- listed on RLS under TO data
2. Simple-Special: a turn to HDG or NavAid is required before reaching 1000'. FRA remains 1000' unless specified.
- MANDATORY in IMC
- May request vectors if available
- If not available, comply w/Special DP till 3000'. Then you may proceed on course
- listed on RLS under TO data
3. Complex-Special: issued when the engine failure procedure is too complex to fit in the Special DP table or OTHER (terrain) considerations MUST be taken into account.
- Ensures safe obstacle clearance till reaching a safe engine failure altitude
- Specifically designed for a published DP
- Charted in Jepps
- MANDATORY IMC or VMC
What is considered a WET rwy?
- Shiny appearance
- Thin layer of water: 1/8" or 3mm covering 100% of rwy
-Not WET: If DRY spots, no standing water
What is considered a contaminated RWY?
- 25%+ covered w/ water, slush, wet/dry snow
- less than 25% = Patchy
What is considered Compacted Snow on a RWY?
- considered contaminated
- solid mass which will resist further compression
- holds together
- will break into lumps if picked up
Whats the difference between:
- Standing water
- Wet Snow
- Dry Snow
- Wet Ice
- Standing water: accumulated water from heavy rain or poor drainage
- Slush: Partly melted now or ice, watery
- Wet Snow: snow that turns to water if compacted
- Dry Snow: Fresh snow, compacts w/compression. Doesn't melt
- Wet Ice: rwy condition w/LOW braking, caused by melting compacted snow or ice
What do these codes mean for WX mean?
- FRZN: Forzen
- IR: Ice on RWY
- PLW: Plow(ed)
- PSR: Packed Snow on RWY
- SIR: Compacted Snow and ICE on RWY
- SLR: Slush on RWY
- SN: Snow
- WSR: Wet Snow on RWY
What restrictions apply to Take-Offs on Wet, Slippery, and Contaminated RWY's?
1. Reduced Thrust TO PROHIBITED
2. TO PROHIBITED w/"NIL" braking report
3. TO PROHIBITED w/level 3 contamination
What is the MAX Reduced Thrust for TO?
- 25% (FCM will not allow more)
- PROHIBITED Contaminated RWY
- PROHIBITED Special DP (SNA)
What is PMRTW and MFPTW?
- PMRTW: Planned Max RWY TO weight
-issue if you're a 747/Heavy
- MFPTW: Max Flight Plan TO weight:
- max TO weight for which the flight plan is valid considering all flight planning limits except MRTW.
- Final MTOW can NEVER exceed MFPTW
What do you do if you have TO data on the RLS for Dry RWY, but ATIS around time of departure shows WX moving through with Rain, gusty winds, including windshear
PH 2.5 / 2.12
- If ACARS Available: Run TO data for WET rwy and WND SHR.. Ie: Max Performance
- If NO ACARS only RLS: Contact Dispatch. Get NEW TO data
** Remember: Reduced TO PROHIBITED with contamination**
What do you do if OAT exceeds MT?
- MT: Max Temp (actual/assumed) for which TO is allowed for the MTOW, section conditions, and TO config
- If OAT exceed MT:
1. Reduced thrust not permitted
2. Actual Air Temp MUST NOT exceed MT
3. Contact Dispatch for NEW TO data
What do you do if TO data on RLS is based on calm winds, but actual conditions show a tailwind or windshear?
- Contact Dispatch for new (TLR) TO data
- Use of data is NOT allowed with a Tailwind
- unless TO data reflects data for a TW
Which TO METHOD is generally DEFAULT?
Method 1: when not limiting to flight plans TO weight.
