Hello all!
I am currently studying the Pooleys Navigation book. I have just finished the airspeed section and onto the practice questions.
I'm stumped with the following:
"Your destination is 77nm away; you must arrive in not less than 42 minutes. If you are flying at FL50 and the OAT is +10 degrees Celsius, what is the minimum CAS required to arrive at the desired time? Assume no head or tail wind component."
So far, i have had no issues with using the whizz wheel, but the annoying thing is, there were no examples for this type of question in the airspeed chapter!
The furthest i have gotten is moving the wheel to FL50 and +10 degrees, but i dont know how to use the distance and time to find the CAS!
Any help would be much appreciated. :-)
Thanks,
Fran
