POWER SETTINGS
| Phase | Setting |
|---|---|
| Takeoff (autothrottle) | TO or TO FLEX on the TRP; autothrottle advances to the EPR limit, clamp mode locks the levers at 60 KIAS |
| Max takeoff rating | 20,850 lb thrust, available via ARTS actuation or manual throttle movement |
| Normal takeoff rating | 20,000 lb thrust, the rating to be set with ARTS operative |
| Reverse thrust (slippery runway) | 1.3 EPR maximum on slippery portions except in an emergency |
| Reverse thrust (rudder authority) | rudder provides no control at about 1.6 EPR reverse |
FLAP SCHEDULE
| Setting | Max Speed | Use |
|---|---|---|
| Flaps 0.1 to 13 deg | 280 KCAS / M0.57 | Includes the 11 deg takeoff detent |
| Flaps 13.1 to 20 deg | 240 KCAS / M0.57 | Includes the 15 deg takeoff detent |
| Flaps 20.1 to 25 deg | 220 KCAS / M0.57 | Approach |
| Flaps 25.1 to 30 deg | 200 KCAS / M0.57 | Includes the 28 deg landing detent |
| Flaps 31 to 40 deg | 195 KCAS / M0.57 | Includes the 40 deg full landing detent |
| Slats extended, takeoff (17.8 deg) | 280 KCAS / M0.57 | Takeoff |
| Slats extended, landing (21 deg) | 240 KCAS / M0.57 | Landing |
| Autoslat extension | 280 KCAS / M0.57 | Automatic slat extension |
ENGINE LIMITS
| Parameter | Value |
|---|---|
| 20,850 lb (5 min, flat rated to 84 degF) | |
| 20,000 lb (5 min, flat rated to 77 degF) | |
| 20,850 lb (10 min) | |
| 630 degC for 2 min, 625 degC for 5 min (10 min engine inoperative) | |
| 595 degC for 2 min, 590 degC for 5 min | |
| 580 degC | |
| 475 degC (500 degC when AFM Appendix 11 is used) | |
| 625 degC | |
| 135 degC continuous, 165 degC transient (15 min limit) | |
| 40 to 55 psi | |
| JT8D-217C/219 minimum N1 vs EPR and OAT table; e.g. 1.95 EPR needs 82.9 pct N1 at -20 degC, 87.9 pct at +10 degC, 92.5 pct at +40 degC | |
| crosscheck for EPR error due to a plugged Pt2 probe only, not for setting takeoff thrust; actual N1 during takeoff will normally be higher than the tabulated minimum |
