1. Find CAS (Calibrated Airspeed in kts).

2. Find EAS (Equivalent Airspeed in kts).

3. Find Pressure Ratio: .

4. Find Mach.

5. Find Actual Outside Air Temperature (ambient temperature).

6. Find Temperature Ram Rise.

7. Find Density Ratio: .

8. Find TAS, True Airspeed in kts.

9. If you are landing into an airfield in mountainous terrain at a field elevation of 3,000 ft

MSL (Mean Sea Level) and the field outside air temperature is -24 deg C, according to

AC 91-XX Draft Appendix 2, how should you adjust your approach arrival procedures

with a Final Approach Fix (FAF) at 5,000 ft MSL and your Minimum Descent Altitude

(MDA) at 3500 ft MSL?
