-==== Editing Pitot Wing Data - CapeEx19 ====+===== Editing Pitot Wing Data - CapeEx19 ====
 +==== Reason for editing ==== 
 +  - During ongoing aircraft field research in Florida in 2019, the aircraft's wing pitot sensor was found to be providing erroneous readings. 
 +  - During the creation of the physical file, the process_all script consolidates the CIP pitot pressure into the wing pitot pressure spot; consequently, the anomalous data is utilized to generate the .basic.raw file. 
 +  - The CIP pitot pressure is about 10 mb lower than the nose pitot pressure. 
 + 
 +=== How to remove the corrupted data === 
 + 
 +  - Connect to vpn.ndus.edu through Global Protect 
 +  - Open and log into the Littlestorm server through PuTTY. 
 +  - After logging in, type in the command: **cd /nas/und/Florida/2019/Aircraft/CitationII_N555DS/FlightData** 
 +  - After going to the FlightData directory, look inside it for a subdirectory named after the specific date of flight you want to see. For instance, I chose the 20190803_142455 flight data to make changes. 
 +  - After selecting the directory of interest, type: **cd PostProcessing** 
 +  - Navigate to the **.physical.raw.gz** file. 
 +=== Editing the file and data inside it: === 
 +  
 +   - First, if the file is compressed, meaning it is in .gz format, then decompress it using the command: **gunzip 19_08_03_14_24_55.physical.raw** 
 +   - Once the file is in decompressed form, type: **aplot 19_08_03_14_24_55.physical.raw** 
 +   - This command will open ADPAA Aplot. 
 +   - Select **'Pitot_Wing'** and then **XY Plot** 
 +   - To look at the time interval of this flight, click the Tools tab located at the top of the bar. 
 +   - Under the Tools section, click **"Statistics"**. A side window will be opened, which displays the X-span (time interval). 
 +   - Notice the Minimum and Maximum time. 
 +   - Under the File tab, go to the "Add Edit" option. 
 +   - Type the **minimum time** as Start Time and the **maximum time** as End Time. 
 +   - Type in the editor name 
 +   - Select the parameter as Pitot_Wing 
 +   - Then, please specify the reason for making the edit. For example, I might indicate "Not connected, negative values." 
 +   - Click **"Store Edit info"**. This will create a .physical.edits file in the directory you are in.  
 +   - Proceed to the File tab and select **"Apply edits"**. This action will generate a .physical.cleans file within the directory.  
 +   - The physical. cleans file will exclude data from the Pitot_wing sensor. 
 +
