#2. What is the TAS when pressure altitude = 15000 ft, OAT = -15°C, CAS = 145 Kts?
#3. What is the TAS when pressure altitude = 20000 ft, OAT = -20°C, CAS = 200 Kts?
#4. Cruising at FL 390, M0.84, is found to give a TAS of 499 Kts. The ISA deviation at this level is?
#5. The velocity of the speed of sound at sea level in the standard atmosphere is?
#6. If outside air temperature at 35000 ft is -40°C, the local speed of sound is?
#7. An aircraft is flying at 310 kts TAS at FL290, Temperature deviation is -6°C. The local speed of sound is?
#8. An aircraft flying at FL 310 is cruising at a CAS of 280 Kts. If the correct outside air temperature is -48°C, this will give a mach number of?
#9. The temperature at the airport is 23°C, what is the local speed of sound?
#10. An aircraft is flying at 1100 Kts TAS at FL650. A change of 0.1M gives a change of 57 Kts TAS. The temperature deviation at FL650 assuming an ISA atmosphere is?
#11. An aircraft is flying at FL290 at 500 Kts TAS, 0.86M, the temperature deviation is?
#12. An increase of 0.15 in mach number results in an increase of 93 Kts TAS. If temperature deviation from ISA is +9°C, the FL is?
#13. An aircraft is flying at FL 390, temperature is -56.5°C at mach 0.85. The TAS is?
#14. An increase of 0.15 mach results in an increase of 93 Kts TAS. The local speed of sound is?
#15. An increase of 0.15 mach results in an increase of 93 Kts TAS. If temperature deviation from ISA is +5°C, the approximate flight level is?
