Solve the following problems using the given preflight information
1. The weatherman predicts winds at 25,000' to be 185/50 and at 30,000' to be 230/80. If
your true course is 295, what altitude should be flown to attain the greatest ground
speed? __________
The weather shop predicts winds to be 230/45 with OAT of -10. You plan to fly a
2.
TC of 330 at an IAS of 186 kts. Your planned calibrated alt will be 15,000' using the
local altimeter of 27.56. Find:

You are planning for your first cross-country flight. Your planned TAS is 300 kts and
calibrated altitude is 30,000'. The forecaster is predicting winds to be 280/22 kts
with an OAT of -60. The local altimeter will remain constant throughout the route at
29.35".
a.
What will your IAS be? __________
b.
If the distance from point A to B on the flight is 349 nm and the measured TC
is 345, what time will you arrive at point B if you depart point A at 1315
GMT? __________
4.6-124
