Proficient use of appropriate performance charts, tables, graphs, or other data to determine airplane performance and limitations for all phases of flight.
Bottom line
The pilot should be thoroughly familiar with the airplane’s performance capabilities and limitations in order to make an informed takeoff decision as part of the preflight planning. To be avoided above all is attempting to continue flight when it is not within the airplane’s performance capability to do so.
Key numbers

| 100 fpm with both engines operating | All-engine ceiling |
| 50 feet above takeoff elevation under ideal circumstances | Accelerate-go |
| minimum speed for intentional engine failures | Vsse |
