Alternatively, some pilots live by the motto, “Aimpoint, airspeed.” In other words,<br />
using the velocity vector or visual steering, point the aircraft such that it is heading<br />
for the end of the runway (the aimpoint). Next, adjust airspeed to the appropriate<br />
landing speed. By maintaining both attributes, the aircraft will follow a proper<br />
approach.<br />
Always use the proper speed to maintain the correct AOA during final<br />
approach. The following table provides an estimation of the speed required for<br />
empty aircraft:<br />
Aircraft (Clean) Final Approach Speed Touchdown Speed<br />
Su-25 280 km/h 210 km/h<br />
Su-27 300 km/h 250 km/h<br />
MiG-29A 280 km/h 2<strong>35</strong> km/h<br />
F-15 125 knots 115 knots<br />
A-10 120 knots 110 knots<br />
hIf flaps are unavailable, increase speed by 10 knots or 15 km/h. If<br />
carrying significant fuel or stores, increase approach speed as necessary<br />
to maintain correct AOA.<br />
Always steer to land the aircraft with the nose wheel directly on the runway<br />
centerline. As the saying goes, “The centerline is for pilots. The rest of the runway<br />
is for passengers.”<br />
9.003 Instrument Landing System (ILS)<br />
Both Russian and U.S. aircraft use the same Instrument Landing System (ILS). The<br />
ILS uses two needles to guide the aircraft down the proper approach trajectory,<br />
called the glide path. The horizontal glideslope deviation bar shows the desired<br />
altitude. The vertical, localizer deviation bar shows the desired heading. When the<br />
needles are centered, the aircraft is flying the correct glide path. If the aircraft is off<br />
course, the needles drift outwards. Always fly toward the needles; if the localizer<br />
bar drifts to the right, turn right. If the glideslope bar drops, descend.<br />
