1 2700 @20 knots 270@20 WIND DESIRED TRACK HEADING HEADING VS TRACK

2 Tail wind exists so consider a lower power setting. With 73% and 2600 rpm we get 119 airspeed and 133 kt groundspeed. With 55% and 2350 rpm we get 108 airspeed and 120 kt groundspeed. It makes a difference of 2 extra minutes! Engine stress is much less, fuel flow is less 270@20

Set heading point will be overhead Kingston Power Setting: Power Setting: Closest to 55% at your cruising altitude of 5,500’ ASL Weather: Weather: Assume temperature is 10°C warmer than standard at all altitudes; Altimeter setting 29.92” ; Wind at 5,500 ASL forecast to be 220°T at 18 knots Pilot Licence: Pilot Licence:PA321123 Allow 6 minutes at cruise power for circuit before landing at Ottawa. For start, run-up, takeoff and climb, allow fuel as indicated on the charts. Proposed departure time is 0200 EDT. Allow 6 minutes at cruise power for circuit before landing at Ottawa.

15 pick the cruise altitude chart closest to our planned cruise altitude. pick the cruise altitude chart closest to our planned cruise altitude. 2400 RPM is in the right range (55%) when we interpolate. 2400 RPM is in the right range (55%) when we interpolate. At 10˚C above standard we interpolate halfway between standard and 20˚C above standard. At 10˚C above standard we interpolate halfway between standard and 20˚C above standard. KTAS = 107 KTAS = 107 GPH = 8.0 GPH = 8.0 ****DISCLAIMER**** You can interpolate exactly between altitudes as well (your instructors may want this), however, for this course, the technique used in this example is all that is required.

16 Finding IAS First find CAS on E6-B First find CAS on E6-B Standard temp at 5500 = 4˚C Standard temp at 5500 = 4˚C +10˚C +10˚C 14˚C 14˚C Assume standard pressure for this example Assume standard pressure for this example Set 5500 against 14˚C on the density altitude window Set 5500 against 14˚C on the density altitude window Find TAS of 107 on the outer scale and read CAS on the inner wheel. KCAS = 97 kts Find TAS of 107 on the outer scale and read CAS on the inner wheel. KCAS = 97 kts
