OPT Flashcards
What is the approach climb gradient in the opt ? What configuration for the aircraft is this calculation based on ?
The approach climb gradient is based on an engine inoperative, the aircraft at maximum certified landing weight, landing gear retracted, approach flaps set, and takeoff thrust on the remaining engine
What is the landing climb gradient in the opt ? What configuration for the aircraft is this calculation based on ?
The landing climb gradient is based on all engines operating at takeoff thrust, full landing flaps deployed, landing gear extended, and the aircraft at maximum certificated landing weight.
What does EO-GO represent in the opt ?
the total distance it will take you to start your takeoff roll, lose an engine, continue the takeoff, and reach 35 feet at V2.
What is the definition of balance field ?
V1 usually “balances the field.” V1 identifies an engine failure speed where the distance to abort and the distance to continue the takeoff are the same. That’s called a “balanced field.”TODA equal to ASDR
Why do we initially only use the current conditions ( ATIS ) on the TKO dispatch page without the ZFW or CG ?
Each pilot will first enter the current conditions into the TKO Dispatch page then verify the MAXIMUM PERFORMANCE WEIGHT for the expected runway for departure. Both pilots will cross check the OPT data date for currency, the N- Number of the aircraft being used, the conditions entered into the TKO Dispatch page, and the maximum performance weight calculated by OPT. The FO will record this weight in box 2 of the Weight Data Record form.
- Why would the calculated opt approach climb gradient be important on a missed approach procedure ?
- What would you do if you do not meet the minimum missed approach climb gradient in the event of a missed approach ?
The approach climb gradient assures the crew the aircraft will have the appropriate performance to execute the published missed procedure on a single engine.
Follow a appropriate procedure prescribed by the OPT or the company engine out procedure for the desired runway normally found in the Jeppesen charts.
What does the I/C represent ?
Improved Climb Performance Takeoff
Climb Performance Takeoff (Improved)
When not field length limited, an increased climb limit weight is achieved by using the excess field length to accelerate to higher takeoff and climb speeds. This improves the climb gradient, thereby raising the climb and obstacle limited weights. V1, VR and V2 are increased and must be obtained from dispatch or by airport analysis.
Note : this may be found in the Boeing Flight crew training manual
Do we plug in the CG for OPT performance calculations ?
No. The OPT will calculate all performance numbers correctly without a CG value. Since it is only used for a reference, there is no need to enter the CG value into the program.
