Concepts / Mentality / Truisms

Some things never change - no matter how 'creative' we are and it behooves us to listen to history.

  • Aeronautical Decision Making (see CRM and SRM)
  • Altitude = Airspeed
  • Altitude is life
  • Always care about your pre-flight
  • Avoid roads unless zero other options
  • Checklists: do them.  Do what you say, say what you do.
  • Compliance Philosophy (FAA)
  • Decision Making (see CRM and SRM)
  • Emergencies, the "5 Nevers" (see Emergencies)
  • Engine Failures (see Emergencies)
  • Fly the aircraft until its chocked
  • Flying, the "5 Nevers"
    • You never have to takeoff
    • Never takeoff without seeing the fuel
    • Never takeoff without using the checklists
    • Never determine you "have to get "there"
    • You never have to land on this approach
  • Fuel:  know your fuel reserves – day/night, VFR/IFR
  • Going around – if you have power and fuel, it’s always an option
  • Heavily loaded airplanes are different beasts
  • Increased angle of bank = increased stall speed
  • Instinct isn't always your friend
  • Landing
    • Always plan on 1) landing and 2) going around
    • Don’t force an airplane to land
  • Max crosswind component exists for a reason
  • Only mix water with float airplanes
  • Personal:  if there is anything making you hesitant to fly…speak up!  There’s always another day.
  • Plan, Brief, Do, Review, Renew (with anything)
  • Poor judgement can overcome great skill.
  • References:  if you’re referencing study material that isn’t in the FAR or AIM or from an FAA source (such as this website), always cross-check it. 
  • Situational awareness doesn’t care if you’re in the air or on the ground.
  • Responsibility
    • Take personal responsibility for your flights/checkrides.  Yes, your instructor is accountable for what and how he/she teaches you, but no one can make you study and/or prepare.  This goes hand-in-hand with the PIC mentality.  YOU ARE taking the airplane’s book.  YOU ARE doing the walk-around.  YOU ARE flying the airplane.  The sooner you act like the other person is your spouse, significant other, friend, someone who can give you zero assistance, the better off and prepared you’ll be…for anything.
  • Stalls
    • Climbing turns: high wing stalls first
    • Descending turns: low wing stalls first
  • Task Saturation – fall back on a ladder of priorities
    • Attain & maintain flying airspeed
    • Communicate
    • Ensure a clear flight path
    • Fly airplane to proper position
    • Work avionics and other cockpit technology
  • Traffic pattern - never underestimate it
  • Treat every propeller like a live one
  • Turbulence?  Always a good idea to slow down
  • VMC into IMC (have a plan)
  • What are you doing now?  What will you do next?  What will you do after that?
  • Why good pilots makes bad decisions:
    • Wired to make quick assessment, tag it with emotion, made decision, and move on
    • We’re inclined to stick with a decision once made
      • We’ve done this before (history)
      • Self-interest (emotional bond) to stick with it which leads to
      • Discounting adverse information (resistance to change)
  • Wings always stall at the same angle of attack
  • Weather:  If the WX makes you nervous, what makes you think the flight will calm your nerves?
  • Weight, balance, performance:  before every flight

Maneuvers / Execution / Techniques

Articles:
Braking: - see Landing (separate page).

Climbs / Descents:
Coordination / Rudder / Yaw:
Emergencies:  separate page.

Energy Management:  From AFH Chapter 4 - Energy management can be defined as the process of planning, monitoring, and controlling altitude and airspeed targets in relation to the airplane’s energy state in order to:
  1. Attain / maintain desired vertical flightpath-airspeed profiles.
  2. Detect, correct, and prevent unintentional altitude-airspeed deviations from desired energy state.
  3. Prevent irreversible deceleration and/or sink rate that results in a crash.
Final: see Landing.
Go Around(s):
  • 8 times or 9 times you should go around.
    • NOTE: They mention "bad bounce" - not "bounce".
  • Avoiding traffic during a go-around. (Vid 184).
  • Botched go around.
  • Go-around technique. (Vid 96).
  • How to fly a go-around.
  • The aircraft will always go UP and LEFT (assuming a single engine piston aircraft)
  • The 'binary' go-around.  Have you been instructed, or is it your own notion, that a bounced landing should be followed by a go-around?  If so, be careful of any 'binary' flying.  Physics are binary but how we handle things is usually not.  Here is a video of a bounce into a go around.  The plane could have easily landed from the bounce and if you're going to go around, do it correctly.  The video might be hard for some to watch.

Visual Flight: - how to enforce it

  • If you have students who stare at the gauges, my first recommendation is to cover them.  So as not to keep them from recognizing a 30° bank turn, I let them see it.  I cut a suction cup to hide the ADI minus the 30° bank turn.  Why?  Because I want them to hear, feel, sense their energy state by using their nose position.  This is also where the stall warning comes into  effect.
Yaw / Coordination / Rudder: see Coordination above.

Upset Prevention and Recovery Training

Upset and recovery training might be (it will be) the best training you ever receive!

First and foremost, ask yourself, "am I confident to recover from any unusual attitude (upset)?"  If the answer is 'no', you are at the right place.  I will make you comfortable!

Upset Prevention and Recovery Training (UPRT) is training to overcome the most lethal threat in the air – loss of control in-flight (LOC-I).

But what is an “upset”?

  • If you’re a numbers person, you can use this…
    • Pitch > 25° nose up or
    • Pitch > 10° nose down or
    • Bank > 45° or
    • Remember, these numbers are if you didn't expect/force it
    • Airspeed inappropriate for the conditions (all if unexpected)
  • If you’re not a numbers person (like me), I would use this: ‘anything beyond what you expect’.
    • I.e., the airplane is not doing what you expect it to do
    • I.e., control inputs are not doing what you you expect
    • It is the simulated IMC unusual attitudes but well beyond.
    • Think of this...if I give you the airplane in a vertical attitude, what do you do?
  • Spins
    • Academics for spins: Spin Training - FIG style
    • "PARE" is the recovery.
      • Power (idle)
      • Ailerons (neutral)
      • Rudder (full opposite direction of spin)
      • Elevator (push to at least neutral - nose down)
    • Four steps of spin recovery, explained.
    • Spins are a bit different then other upsets (UPRT). You can't just push yourself out of a spin. You need to reduce the power and stop the rotation.
    • An airplane has to stall before it can spin.  Prevent the stall, prevent the spin.
    • Sluggish control responses.  This should make you 'very aware'.
    • Uncoordinated flight.  Use your body when busy elsewhere.
    • The danger duo.  Cross-control and slow = be very aware.
    • Buffet.  If your airframe is shaking, you're approaching a stall.
    • Profile or Spin Card
    • See More Information below.

The training builds the time-sensitive, and typically, counter-intuitive actions required to prevent or recover from lethal upsets.  For example, when a power-off stall rolls right, the human response is to pull back and roll left.  Ironically, those are the last things you should do.  But this is the fun of upset training.  It takes you from a state of wondering/guessing what to do to a state of knowing what to do.

Just so you know, this is the sad reality of GA pilots.  They ‘exploit’ about 11% of the aircraft’s capabilities.  Which, if we're honest, is not good.  Our aircraft can do so much more than we're willing to try.  Turn your airplane, own your airplane, exploit your airplane.  We will help you do just that.


Not only is UPRT a great acronym, it actually reads "upright".  And the steps are straight forward.
  • "Upset" and/or "uncouple".  Ideally, "Upset, uncouple."
    • If you're a crew (or not) it's very powerful to audibly announce that you are "upset".
    • If you're on automation (autopilot), you should uncouple (disengage) any automation.
  • "Push"
    • This is the most important step.  Unload the aircraft to reduce the AOA.
  • "Roll"
    • Get your wings level to maximize lift.
  • "Thrust"
    • Analyze your power state and adjust appropriately.  What does that mean?  Well, if you have plenty of energy, you don't need more power.  If you're in a low energy state, you will need power.  You can use Vx as a dividing line.  I.e., if you're below Vx, you very likely need more power.  If you're above Vx, you probably don't need more energy.
  • "Stabilize".  This is not technically part of the UPRT acronym, but it's a great way to verbalize (and do) the last things(s) required to stabilize the aircraft.  Is it on a good flightpath?  Is your energy state where you want it?  Are you safe?
Syllabus
