Study These Flashcards
A

Greater of:
- Accelerate with all engines operating and come to a complete stop with engine failure at Vef or,
- Accelerate with all engines operating and come to a complete stop with all engines operating

23
Q

Takeoff Climb Limited Weight

Study These Flashcards
A

To achieve 2.4% Gross Climb Gradient at the beginning of the Second Segment with OEI

24
Q

Tyre Speed Limits

Study These Flashcards
A
  • B737-800: 195KT,
  • B737-8200: 204KT
25
Balanced V1
OEI T/O distance equals to Accelerate Stop Distance
26
Optimum V1
- Normally used for all T/O Calculations, - To calculate highest allowed weight by taking advantage of stopway and clearway
27
Standard EOSID
- Straight ahead, - Usually at 15NM or more from the physical start of the T/O RWY
28
Special EOSID
- Turn required before joining hold pattern with or without speed restriction, - 15 degrees AOB up to V2+20KT, 25 degrees AOB above Flaps Up Speed, - Observe speed restriction even above MFRA, - OPT calculated MFRAs are cold temperature corrected (RTOWs are not)
29
Standard SID Gradient
3.3% otherwise depicted specifically on the chart
30
Obstacle Clearance Path
- Starts from 35FT at the end of the TOD, - Vertically clears obstacles by at least 35FT, - Horizontally by Half the wing span (18m) + 60m + 0.125 x D (max 900m), - D: Distance from DER - In case of a bank > 15 degrees, clearance increases to 50FT
31
Minimum Turn Height
- Not before DER, - Not before 59FT (half of wingspan)
32
EOSID Holding Patterns
- Where possible AIP holdings are used, - Otherwise calculated as 5NM legs with 2NM turn radius
33
MCT Selection
Must be set after 5 minutes of T/O Thrust
34
Engine Failure During Climb Out
- Below 1000FT AAL, follow EOSID with speed restrictions, - If Deviation Point or speed for EOSID turn has been passed, continue with the SID or ATC, - Deviation Point: Point at which the EOSID diverges from SID
35
Driftdown Path Clearance
- Clears all terrain and obstacles within 5NM of intended track by at least 1000ft, - From cruising altitude to an aerodrome, clears all terrain and obstacles within 5NM of intended track by at least 2000ft, - Must have positive gradient at 1500FT AAL at the related aerodrome
36
Landing Dispatch
- Dry RWY: Actual LDR x 1.67, - Wet RWY: Actual LDR x 1.67 x 1.15

39
Thrust Reverser Inoperative Landing Restriction
For Dispatch: - On OPT REV credit may be included for contaminated RWYs, - On QRH no credit will be used Enroute: - Use OPT NNC/MEL - On QRH no credit will be used

Selected when Wing AI expected to be used after T/O and below MSA

44
MFRA / MFRH
- Company policy uses 1000FT AAL as a minimum MFRH, - OPT calculated MFRA includes cold temperature correction
45
Thrust Reverser Credit for Takeoff
Only when dispatching on a Wet Runway and: - With both Thrust Reversers operative, - Anti-skid operative, - All Brakes operative Regulations allow deceleration credit for: - One thrust reverser in an OEI case and, - Two thrust reverser in all engine case
46
Default Thrust Reduction and Acceleration Heights
- Thrust Reduction: 1500FT, - Acceleration: 1000FT
47
Missed Approach Climb Gradient
- Default 2.5%, - Where higher MACG present, ATC may allow standard 2.5% on request
48
OPT Dispatch Landing Credits
- Assumes MAX Manual Braking, - Auto Speed Brakes, - Temperature and RWY Slope not included, - REV may only be selected for contaminated RWYs
49
Autoland Landing Distance Increment
- Flaps 40: 140m, - Flaps 30: 185m
