Dancing with the Electric Aluminium Submarine


Position: 3 Nautical Miles Final on Approach to Kuala Lumpur Runway 14 Left
Altitude: 1100 Feet above mean sea level
Weather: Dry season, hazy, winds calm.

ONE THOUSAND - the automated voice announced.

"Now, watch your pitch attitude - It's at +2.5 degrees now, ok glance RIGHT over at your vertical speed indicator, -800 feet per minute, now a quick glance LEFT to your airspeed, target for this approach is 142 knots (keep it within +10/-5 of the target!), now BACK to your pitch attitude - now its +3.0 degrees" (keep it approximately between the 0 to +3.0 degrees sweetspot)

While doing the above, look outside and put the extended runway centerline in between your legs. How do you line her up between your legs? Before you even think of doing anything, glance at the miniature airplane on your PFD (Primary Flight Display). Decide on a heading, lets start with 10 degrees from your current heading. Bank the miniature airplane towards the direction of the extended centerline. How much bank? Start with 5 to 10 degrees bank. OK....now I am banking 10 degrees RIGHT....how do I stop the aircraft from turning you asked? Smple, just level the wings of the miniature aircraft. ok now hold this new heading with wings level and WAIT. (while doing the pitch attitude DANCE in the paragraph above)

What are we waiting for Captain? Glance outside, has the extended runway centerline moved inbetween your legs? Yes? Then look back at your miniature airplane, bank back to your original heading, roll wings level and HOLD it there. Glance outside after that, is it lined up between your legs? No? repeat the above. Yes? Hold the miniature airplane steady.

Just do the above 3 paragraphs in repetition. The closer you get to the runway the faster your scan of the PFD, the quicker and more precise your correction is required.

Easy waltzing with a 75 tons Lady.

Now throw in gusty winds, afternoon thermals, low visibility associated with heavy rain and thunderstorms.

Your DANCE will become slightly more interesting now.

But still as easy as riding a bicycle if you follow the above 3 paragraphs and PRACTICE.

Like our friend Saadi says:
"How do I get to Carnegie Hall? Practice. Practice. Practice."
