"When people say pitch for airspeed, power for altitude, I tell them on takeoff not use any power, just give me some pitch. If your theory is correct, then pitching us down the runway should give us all the airspeed we need for takeoff!"
I got a kick out of that.

OK, I'm going to both agree and disagree. Flying it centered is the way to go PROVIDED that you're not following something large enough to create a wake turbulence issue for you. For example, lets say you're sliding down the ILS in a light jet and you're following something like a B777. I'm going to want to be a dot high to keep out of his wake. If I'm going to do it in a small jet, you really ought to seriously condiser doing it in your trusty 172. I'm also going to make sure I land down the runway a bit. Remember, when you're dealing with truly low minimum approaches you're also frequently dealing with fog and when you're dealing fog you don't have a lot of wind - those pesky wingtip vortices can hang around for a while. The key to flying IFR is being aware of the big picture - situational awareness if you please.minitour said:Center it up if possible...

It seems to me that you're still making it way too difficult - 4 scenarios for Pete's sake! Keep it simple. Pitch for glide slope, power for airspeed. Everything thing else resolves itself without a bunch of mental analysis and it works just fine in every airplane you're likely ever going to fly from a Cessna 150 to a B747.Bernoulli said:Perhaps many of us use two different techniques because we are only looking at one side of the coin. When you think about trying to hold the glide slope, we often only think of two situations (above GS or Below GS)... when in reality there are four situations, each of which should be controled differently regarding pitch and power.
1. below glide slope and fast (pitch for glide slope and leave power alone)
2. Below glide slope and slow (Use power to get back on glide slope and get airspeed back up by holding pitch the same)
3. Above glide slope and fast (Reduce power to get glide slope and get speed back to approach speed while holding pitch the same.
4. Above glide slope and slow (pitch for glide slope by increasing pitch down a bit and leave power on approach power setting.
Of course every approach will not be the same due to the velocity of the winds and therefore tweeking both pitch and power is required.
NYCPilot said:According to the FAA Instrument Handbook, the proper technique for flying the ILS is to pitch for glideslope and use power for controlling airspeed. This has been the technique I've used and it seems to work pretty well. It also seems more intuitive when making the corrections. Pitching for the glideslope needle seems more visually logical as well as adjusting power with the throttle to regulate the airspeed.
I also think that you will find that the corrections can be made more quickly and more accurately. The ability to pitch for the glideslope gives you more control as to the rate of pitch movement that allows you to get back on the GS.
Although pitch and power must both be manipulated in order to remain on speed and on the GS, it is much easier to think in terms of using pitch for the GS and power for the airspeed.
