17. Su-27: Introduction, Navigation and ILS Approach (Part 2)

34. The last navigation sub-mode is indicated as "ПОС" ("Landing"). Its designed to guide you to the runway threshold using the ILS final approach system.
35. Currently, we are headed away from waypoint 2 above the clouds at an altitude of 4,000 m.
36. The navigation system director circle on the HUD is indicating the direction to waypoint 3. Note the assigned airspeed and altitude values on the HUD above our current airspeed and altitude.
37. Looking at the HSI, the assigned course for waypoint 3 is 178 degrees.
38. We'll turn right to approach the assigned course.
39. We'll now follow the director circle to perform the necessary course corrections, at the same time being careful to maintain the assigned altitude.
40. To begin our approach to the airfield, we press "1" to select the "Return" sub-mode and watch the HUD to confirm the selection. We now turn left to head for the airfield approach fix.
41. Now that we're on course, all we have to do is maintain the director circle in the center of the HUD. If we do this correctly, the system will switch to "Landing" mode automatically when we pass the initial approach fix.
42. The navigation system and director circle are directing us to climb to 4520 m.; however, because we are already at 40 km. from the initial approach fix and have begun to descend, well ignore this command.
