Musket Morsels

We all know you can't consolidate the internet or hundreds of peoples' insights, techniques, lessons into a single document.  So, I will consolidate the things I've learned, used, and shared to keep people flying right.
  • 1 - please see "Terms" below (in case they are referenced elsewhere)
  • 1-2-3 From the Knee
    • I use this at the perch.  1 is carburetor  heat, 2 is set your power, 3 is 10 degrees of flaps.  I return to power to refine it, but after it's refined, I leave it alone.
  • Aimpoint vs Landing Point.
    • First of all, I would argue there is no 'landing point' unless you're executing a precision landing.  Normally, the landing point is slightly beyond the aim point.  You'll find many definitions for the aimpoint, but it is where you would crash if you never changed your approach angle.  Since we transition to level, wait for the airplane to lose its lift and then roundout, we will certainly land beyond the aimpoint.  As soon as you transition to level, your aimpoint has served its purpose and you can say thank you as you fly past it.  You will land XXX feet beyond it.  If you wanted to land at brick one, your aimpoint could never be on the runway.  My aimpoint is very seldom short.  In fact, if there is a VASI/PAPI, it's an imaginary line directly across from the lights.  See my VASI/PAPI tutorial.  If there aren't lights, it's usually the first centerline dash after the numbers.  I only bring it closer if the runway is REALLY short.
    • Review the AIM discussion
  • Crosswind controls on the ground
    • The text version in many POHs (such as shown here) take a bit of mental effort - at least they do for me.  So here's my technique...
      • Conventional Gear
        • "Turn Into, Dive Away From".  It's that simple.
        • You turn into (stick/yoke into) a quartering headwind and dive away from (stick/yoke away and forward) a quartering tailwind.
      • Tricycle Gear
        • "Climb Into, Dive Away From".
        • Only difference is 1) back stick/yoke for the headwinds and 2) watch the "diving" away from so you don't overcome prop wash.  Such as in moderate tailwinds.
      • AOPA has another technique if it works for you.
  • Illusions
    • Runways:
      • If it's "WIde" you'll be "HI", if it's "narROW" you'll be "LOW" (those are where you typically end up, not necessarily)
        • You're tying to make it look 'normal'
        • If they have VAPIs (VASI or PAPI) use them!
      • Slope - it's opposite of the slope
        • If it slopes down, you'll likely be higher (than you should be)
        • If it slopes up, you'll likely be lower (than you should be)
        • If they have VAPIs (VASI or PAPI) use them!
  • "Pitch for airspeed" - this implies an unmodified power setting and you can only maintain a speed with pitch (forward-aft stick/yoke).
  • Preflight / Walkaround:
    • The point here is to start from and end where you mount your aircraft.  Piper (and others) and Cessna are clearly different.  Both pics are from the POHs (with edits on the Piper):

  • Skid vs Slip
    • If you skid, you'll leave rubber on the road - TOO MUCH rudder.  You'll  leave a skid mark.
    • Slips then are the opposite - not enough rudder
  • Terms
    • "Abeam the numbers" - I call it the 'perch'.  It's where you (and birds) 'jump off the Perch.  I.e., you start your descent to base, to final, to landing.
    • "Back pressure" - pull back on the stick/yoke, or "Release back pressure" which is the opposite.
    • "Brick One" - meaning the very first inch (or brick width) of the runway.
    • "Buffet" - when the aircraft starts to shake prior to a stall
    • "Chair fly" - to rehearse a maneuver (or anything) before you actually do it.
    • "Grandma turns" - any turn with unnecessarily low bank angle.
      • VFR - anything less than 30 degrees (minus simulated IMC or slow flight)
      • IFR - anything less than 15 degrees (or standard rate which ever is lower) 
    • "Horn" - the stall warning horn - or however the aircraft is equipped
    • "Perch" - what everyone calls the "abeam the numbers" which is 4 syllables longer.  The Perch is certainly when you are abeam the numbers, but it also instills the idea that you "jump" off the perch.  I.e., you start your descent.  Birds don't fly up from a perch, they jump off (down).  Also see "Abeam the numbers" above.
    • "Roll Out" - means to reduce your bank (whatever it is) to zero, so as to roll out of bank.
    • "Unload" - lower AOA, push the yoke/stick forward
    • "VAPI" - I will use this when referencing VASIs or PAPIs.  They only differ in configuration, but the concept is the same.
    • "Wire".  This is the term I use for the approach angle.  3 degrees, right?  The 'wire' is a line between you and your aimpoint.  Ideally, it is always about a 3 degree wire.  You are either above, on, or below the wire.
  • Where do I put the keys?
    • My suggestion is on the fuel selector (or on the floor).  Placing it on the dashboard inevitably lets them slide out of view.  Hanging them on a knob...painful.  Just put them on the center of the floor.
