  1. SELECTED PERFORMANCE EXAMPLES

  2. V1 & VR FOR OPERATING CONDITION A-3?

  3. QNH 1020 => CORRECTION -200FT PA = 4,200 200 = 4,000 FT

  4. FIND V1 AND VR: 133.5K & 139.0KTS

  5. V1 corrections: Temp & PA: +2 Slope: 0 HW (15 kts): +0.45 Ice: +0.80 V1 = 136.75kts VR corrections: Temp & PA: +2 Slope: 0 HW (15 kts): 0 Ice: +0.80 VR = 141.80kts REVISED V1 AND VR: 136.75 & 141.8

  6. (REFER TO FIGURES 59 AND 60.) WHAT IS THE MAX CLIMB EPR FOR OPERATING CONDITIONS T-1?

  7. 1.90 - 0.08 = 1.82

  8. (REFER TO FIGURES 59 AND 60.) WHAT IS THE MAX CRUISE EPR FOR OPERATING CONDITIONS T-3?

  9. 2.02 - 0.08 - 0.04 = 1.90

  10. (REFER TO FIGURES 48, 49, AND 50.) WHAT IS THE GROUND DISTANCE COVERED DURING EN ROUTE CLIMB FOR OPERATING CONDITIONS W-5?

  11. Pick the right chart! 2.02

  12. No wind data: Distance: 73.9NM / Time: 11.3 min = 6.54NM/min No wind GS = 6.54NM/min x 60 min = 392.4 knots Adjusting for headwind: 392.4 knots 40 knots (HW) = 352.4 knots 352.4knots x 11.3 min = 66.4NM traveled SOLUTION: 66.4NM

  13. (REFER TO FIGURE 465.) AT A WEIGHT OF 60,000 POUNDS WITH 35 FLAPS, THE REFERENCE STALL SPEED IS 96 KNOTS
