24. Su-25 Introduction (Part 2)

28.The first navigation sub-mode is 'Enroute'. This is the primary navigation mode used to fly along a planned route. You can select between the navigation points of the route by pressing "LCTRL + ~". Use the Steerpoint Range Indicator to verify selection of the intended navigation point.
29.The second navigation sub-mode is 'Return'. This mode is used for initial approach to the selected airfield. You can select between available airfields by pressing "LCTRL + ~". Use the Steerpoint Range Indicator to verify selection of the intended airfield.
30.The third navigation sub-mode is 'Landing'. This mode is used for final approach and to locate and stay on glidepath down to the runway.
31.We are now on course to Waypoint-1 (WP1) at an altitude of 1,000 m. Once we pass it, the navigation system will automatically switch to WP2.
32.Watch the HSI as the switch is made from WP1 to WP2. The long needle will point directly to WP2 and the short needle will indicate the assigned course heading to WP2.
33.Since we are somewhat off course, we'll make a course correction to line up with the assigned course heading by using two turns. First, we'll turn an additional 30 degrees to approach the assigned course line and then well turn 30 degrees back. As a result, the two needles should line up, indicating we're flying on course directly to the steerpoint.
34.Now try to monitor three instruments together - the ADI, HSI and Steerpoint Range Indicator. Use the latter to check range to the steerpoint.
35.It's very important to perform course corrections accurately and without error, especially in poor visibility conditions.
36.Given that we've corrected properly and are flying on course, we can follow the ADI directors and descend to 500 m.
