מערכת HARS ב - A-10c

מת תפקידה?

למיטב הבנתי, הHARS הוא חלק מהפלטפורמה האינרציאלית של המטוס (INS).

TheHeading Attitude Reference Systems(HARS) is a gyro-platform navigation system that served asthe initial, primary navigation system of the A-10A. As the A-10A evolved into later versions, EGI wasadded and HARS has become a back-up system to the Inertial Navigation System (INS) when the EGIis inoperative. When the INS of the EGI is not available, HARS is selected automatically on theNavigation Mode Select Panel. You can also select it manually when EGI is working, but there wouldbe no good reason to do so. As a backup system, HARS can provide good heading and attitudeinformation, but it can become inaccurate with hard maneuvering or if taken out of Slave to compassmode. It also cannot provide a TVV on the HUD

יש על המערכת פרק שלם בחוברת של הA10 (תחת פרק navigation)

בכמה מילים:
העברת נתונים,גובה כיוון > ל ADI > ל HSI > ל HUD
חשוב לדעת כאשר ה HARS פועל הוא מבטל את EGI הם לא יכולים לעבוד ביחד
צריך לבחור מי מבין השניים יעביר נתונים למחשב המטוס.ובעצם שתיהן מגבות אחת את השנייה,כאשר ה EGI נדפקת ה HARS מתחילה לעבוד אוטומטית,והפוך.


Heading Attitude Reference System (HARS) Navigation
The Heading Attitude Reference System (HARS) is a gyro-platform navigation system that served as
the initial, primary navigation system of the A-10A. As the A-10A evolved into later versions, EGI was
added and HARS has become a back-up system to the Inertial Navigation System (INS) when the EGI
is inoperative. When the INS of the EGI is not available, HARS is selected automatically on the
Navigation Mode Select Panel. You can also select it manually when EGI is working, but there would
be no good reason to do so. As a backup system, HARS can provide good heading and attitude
information, but it can become inaccurate with hard maneuvering or if taken out of Slave to compass
mode. It also cannot provide a TVV on the HUD.
When HARS is active, it provides or removes the following data:
< Pitch and roll signals to the ADI
< Heading data to the TACAN
< Heading data to the compass card on the HSI
< Bank angle to the SAS
< Pitch and roll angle on the HUD
< The Total Velocity Vector (TVV) will be removed from the HUD
< The HARS caution light on the Caution Panel will light

A HARS failure is indicated:
< The ADI OFF Flag will appear
< HUD roll tabs will not be displayed

אוקיי אז לפרק על מערכת הניווט עדיין לא הגעתי ותודה על האינפו'
