Air Temp And AoA Measuring Flashcards
(15 cards)
Why is measuring air temp important
For TAS
To check engine and airframe icing
Aircraft performance and flight planning
What are the 3 type of temp probe
Direct Reading
Remote reading
Total air temp
What is ramrise
The friction created through forcing the aircraft through the air
A direct reading probe needs to account for what
Ram rise
What does a direct reading probe do
Measures OAT and commonly used in low speed aircraft
What is the following:
SAT
TAT
Static air temp or OAT
Total air temp or OAT + Ramrise
What is the sat, tat equation
SAT / TAT = 1 / (1+0.2M²)
What is the ram rise equation
(TAS / 100)²
What are the errors in temp measurement
Insturment and Position
What are the types of AoA sensors
Conical probe and Vane
When will you get a stall warning
A higher Vs + 5kt or 5%of speed (whichever higher)
What are stall warning inputs
Configuration
Thrust
Air/ground logic
AoA sensors
ADC
What are stall warning outputs
Vibration
Lights
Sound
FCC
Systems that use AoA measurements
ADC
Stall warning and protection systems
Flight envelope protection
Wind Shear detection system
What is the difference between SPS and SWS
SPS prevents the stall
SWS only provides a warning
