4. As the clock strikes Midnight, and you are just wrapping up your planning for your first

cross-country, the phone rings. It's your instructor and he wants to change the

destination to San Diego because of the increased training value on the West coast

(and the yearly migration of the Gray Whale is at its peak). You amend your indicated

altitude now to 39,000' to try to make it in one leg. You are also going to fly a CAS of

190 kts. After letting the phone ring for ten minutes the duty forecaster rolls out of the

rack to give you winds aloft of 320/65 kts, an OAT of -75, and altimeter remained

29.35". With a course of 275T, will increasing your altitude help get you to San Diego

any faster? _________ (Hint: Ground Speed...)

Weather west of the Rockies causes your cross-country to be canceled so you are

rescheduled for a Friday afternoon AIRNAV. You rush home, get a twenty-minute

power nap and grab the remote control. The weather channel predicts winds to be

290/65 kts, with OAT of -45. You plan to fly a TC of 335 at an IAS of 300kts. Your

planned indicated alt will be 11,000' using the local altimeter of 28.56. Find:
