Airspeed Calibration
Given: IAS 110kts Flaps 0
CAS 111kts
Altimeter Correction
Given: 100kts Flaps 0
Add 20 feet to Alt.
Wind Components
cos of angle x velocity = Headwind
sin of angle x velocity = Crosswind
Given: Rwy 18 Wind 200/10
Headwind = 9 kts
Crosswind = 3.5 kts
Wind Components
Given Rwy 18 Wind 260/20
Subtract to get angle
260-180=80
Find 80 on radial lines
Find speed (20) on arc
Drop down for crosswind
Go across for headwind
Takeoff Distance
Takeoff distance Problem #1

Cruise Performance
Read Notes!
Given:
Cruise Alt. 4500
65% Power
7.8 Gal/Hr
98knots True
Time, Fuel and Distance to Climb
Given: Elevation 1185, Alt 29.60
Cruise Alt 5500
Find PA:
29.60-29.92=.32×1000=320
320+1185=1505 PA at takeoff
5500+320=5820 PA at cruise
Find 1505 go over drop down
2 min, .4 gal, 2 miles
Find 5820 go over drop down
11.5 min, 1.8 gal, 14 miles
Subtract corresponding numbers and get:
9.5 minutes
1.4 gallons
12 miles
