Is there a place on the display panel where it indicates the outside air temperature. I knew where it was on the 757 - I can't seem to find it in the 737.ThanksChris Catalano

Hi Chris,On the EICAS you will have TAT displayed. Ths is not the true outside air temperature though but rather the temperature of the engine inlets. In SU2 I think you will be able to see the SAT displayed on one of the pages. Can't remember which one now though. Possibly the PROG page.Hope it helps,

>On the EICAS you will have TAT displayed. Ths is not the true>outside air temperature though but rather the temperature of>the engine inlets. Hmm, sounds like there is some confusion here; it's nothing to do with the engine inlets. The TAT probes are mounted on either side of the fuselage below the cockpit windows.The Total Air Temperature is the Outside Air Temperature (also called Static Air Temperature) plus the dynamic heating due to the compression of the air as it is brought to rest in the probe.Depending on probe type and pitot heater and air-conditioning pack use, the TAT display may show the OAT when you are stationary, but the reported ATIS temperature would usually be used when on the ground. Once moving, there will be an element of dynamic heating as a function of TAS (eg. around 20 deg C at 400kts).Air Data Computers calculate OAT using TAT with readings from the pitot and static feeds. OAT should be displayed on PROG page 3 along with some very useful headwind and crosswind components.

Thanks Neil,Feeling a bit embarassed here ;-)Cheers,

Are you saying that on page 3 in the PROG menu of FMC there's supposed to be a reading of the OAT? When in flight I only have one page in the PROG menu. I have wind fuel and destination points, but no OAT reading.

Well, when I say there should be three pages of PROG I mean when compared to the real life FMC. PMDG's software currently implements the first page only.I understand there are plenty of FMC enhancements in SU2, perhaps this is one of them?(Mats, no problem... perhaps you were thinking of Turbine Inlet Temperature?)

You should be very impressed Neil ;) This FMC is simple incredible now. [h4]Best Wishes,Randy J. Smithhttp://img.villagephotos.com/p/2003-5/196432/winglets_lg.jpg

Ahhhh!!!The old T I T for T A T problem again *:-*Slow day at work, sorry :-lolPaul GollnickTechnical Operations/Customer Operational SupportPrecision Manuals Development Groupwww.precisionmanuals.com

Ahhh...now feel relieved, I was beginning to think there was something wrong with my FMC. :)

Mats... You were probably thinking of the "T12" sensor (in the engine inlet at the 2:30 position)?On the 737NG, the T12 sensors provide fan inlet "total" temperature (TAT) to the EECs on the ground and for 5 minutes after takeoff. Only the EEC's see this temperature (it is not shown on the Upper Display). In flight (more than 5 minutes after takeoff), the EEC's use T12 data and TAT data from the ADIRU's. The ADIRU's get their TAT data from the sensors on the nose.Engine TAT sensor and airplane nose TAT sensor data is used in various combinations on Boeing aircraft according to type. It gets very confusing at times knowing what happens on which aircraft.Cheers.Ian.
