  7. Aircraft Performance – Density Altitude – Effect of TemperaturePrivate Pilot Ground School Question # 3292

  8. 3292. What is the effect of a temperature increase from 25 to 50°F on the density altitude if the pressure altitude remains at 5,000 feet? A. 1,200-foot increase. B. 1,400-foot increase. C. 1,650-foot increase. 50ºF5400 Ft. 25ºF3750 Ft. ----------- An increase of:1650 Ft. 5400 3750

  9. Aircraft Performance ChartsPrivate Pilot Ground School Question # 3679

  10. 3679. (Refer to Figure 36.) What is the expected fuel consumption for a 1,000-nautical mile flight under the following conditions? Pressure altitude.................................................. Temperature....................................................... Manifold pressure.............................................. Wind................................................................... A. 60.2 gallons B. 70.1 gallons C. 73.2 gallons 8000 ft 22 C 20.8" Hg Calm Ground Speed = ? Kts Fuel Flow = ? GPH 164 11.5 1000 NM @ 164kts = 6hrs 6 mins 164 / 60 = 2.73 NM per minute 1000 / 2.73 = 365.85 minutes 365.85 / 60 = 6 hours (360 minutes) + 5.8 minutes Fuel = 11.5 gal per hours = 0.19 gal per minute 0.19 x 365.85 minutes = 70.12 gal
