自动油门计算机接收大气静温

khe_2006 · 发表于 2013-1-31 11:13:16

看手册发现FMC和ADIRU都给A/T 计算机发送大气静温信号，手是用来计算备用ＴＲＡ，请问各位大神这两个静温有什么区别？以及这个备用ＴＲＡ有什么用？Ａ／Ｔ计算机的ＴＲＡ不是由ＥＥＣ提供的吗？多谢了．
Flight Management Computer (FMC)
The FMCs send this data to the A/T:
*N1 targets
*Gross weight
*Minimum speed
*FMC altitude
*Static air temperature
*FMC modes
*GMT/Date.
*BITE test information.

Air Data Inertial Reference Unit (ADIRU)
The ADIRUs send this air data reference data to the A/T:
*Computed airspeed (CAS)
*Maximum allowable airspeed (VMO/MMO)
*Uncorrected altitude
*Baro corrected altitude
*Mach
*Static air temperature (SAT)
*Total air temperature (TAT)
*Altitude rate
*Static pressure
*Total pressure
*True airspeed
*Angle of attack (AOA)

SAT is used to calculate a backup TRA limit value
