Version 1.0, 25 September 2011 Flight Briefing Stage 1, Module 4 Copyright © 2011 Ted Dudley

2 Which airplane are you flying?
Hit the esc key Click on “Slide Show” Click on “Custom Slide Show” Select your aircraft

3 Preflight Any questions? On today’s preflight, tell me
What documents are required to be aboard? Identify the function of all the visible antennas on the aircraft. What’s the proper inflation pressure for the nose and main tires? How long can we fly with the fuel that’s aboard?

4 Radio Communications What frequency will you use and what will you say… On initial contact with ground control? When ready for takeoff? When sent to departure control? Let’s pretend we’re going to KFSO for practice patterns. What frequency will you use and what radio calls are required there?

5 Sectional Charts Using the Montreal Sectional, tell me:
What does it mean when an airfield is depicted in blue? What’s the lowest altitude at which you can overfly the Burlington Class C airspace? When is R6501A active? When is R6501B active? What’s the difference between the two? What’s the pattern altitude, CTAF and ASOS freqs, and runway length at KPBG? Would you make left traffic on all runways there?

6 Climbing Flight Advance the throttle to full, apply back elevator pressure to raise the nose of the airplane and right rudder to center the ball As power is increased, the airplane’s nose will rise due to increased download on the stabilizer As pitch attitude increases and the airspeed decreases, progressively more right rudder must be applied to compensate for propeller effects and to hold a constant heading Climb speed is MPH; establish the appropriate attitude and trim for MPH 49R, 93L

7 Climbing Flight Advance the throttle to full, apply back elevator pressure to raise the nose of the airplane and right rudder to center the ball As power is increased, the airplane’s nose will rise due to increased download on the stabilizer As pitch attitude increases and the airspeed decreases, progressively more right rudder must be applied to compensate for propeller effects and to hold a constant heading Climb speed is KIAS; establish the appropriate attitude and trim for KIAS 8ZD

8 Climbing Flight Advance the throttle to full, apply back elevator pressure to raise the nose of the airplane and right rudder to center the ball As power is increased, the airplane’s nose will rise due to increased download on the stabilizer As pitch attitude increases and the airspeed decreases, progressively more right rudder must be applied to compensate for propeller effects and to hold a constant heading Climb speed is MPH; establish the appropriate attitude and trim for MPH 43T

9 Level Off Initiate the level-off at approximately 10 percent of the rate of climb Retain climb power temporarily so that the airplane will accelerate to cruise airspeed more rapidly Trim as you accelerate Good way to remember: PITCH-POWER-TRIM When speed reaches the desired cruise speed, set throttle to cruise power setting and trim for cruise speed

10 Straight and Level Flight
Set power Select some portion of the airplane’s nose as a reference point, and then keep that point in a fixed position relative to the horizon Crosscheck against altimeter and vertical velocity, adjust nose position and trim as required

11 Straight and Level Flight
Of course, if you want to fly straight, wings must be level

12 Descending Flight Descend with power as desired
Airspeed will increase if you leave the power up; trim as required Carb heat on if RPMs below the green arc Flaps as desired But mind you don’t overspeed them! Initiate the level-off at approximately 10 percent of the rate of descent Return throttle to cruise setting after level-off Again, it’s PITCH-POWER-TRIM

13 Level Turns Ailerons in the direction you want to go
While rolling, rudder to overcome adverse yaw Equal amounts of rudder and aileron A little opposite aileron when you’re happy with the bank angle to stop the roll A little less rudder when bank angle is set A little more power and elevator back pressure, especially in turns greater than 30 degrees bank

14 Turn Coordination Keep the ball centered – step on the ball

15 Performing Steep Turns
Clear! Ensure you’re in stabilized, level flight Tell the IP the your target altitude, airspeed, and entry/rollout heading (360o turn) Look in direction of turn and smoothly roll into 45o of bank, maintaining coordination Add a little power to maintain speed

16 Performing Steep Turns
Maintain altitude, speed, and bank angle; make corrections as required Lead rollout by about 15 degrees, and maintain coordination while rolling out Throttle as required after rolling out

17 Tips for Steep Turns Remember it’s a visual maneuver; look over the cowling and adjust the sight picture as required Practice enough to memorize the sight picture for 45o bank and a reasonable airspeed Check sight picture – check altitude trend – make correction Check sight picture – check bank angle – make correction Check sight picture – check airspeed – make correction Repeat from the top until it’s time to roll out

18 Tips for Steep Turns Because of parallax, the sight picture is different when turning left than when turning right When stabilized in the turn, you’ll need: A little rudder in the direction of the turn for coordination A little aileron against the turn to avoid overbanking tendency PTS standards: Altitude, ±100 feet, airspeed, ±10 knots, Bank angle, ±5°, roll out on the entry heading, ±10°

19 Tips for Steep Turns You’ll need to hold back pressure when stabilized
Constant airspeed, level, 45o bank = 1.4 Gs. You’ll feel heavy in the seat. It’s easy to initially let the nose drop too much, then overbank. If the nose is a lot too low (altitude decreasing rapidly), take a little bank out, raise the nose to proper sight picture, put the bank back in

20 Performing Slow Flight
Clearing turns first! Mixture – rich Select and maintain an altitude 1500 AGL minimum Throttle back; raise nose as necessary and trim for level flight Flaps down below flap limit airspeed Note airspeed at which stall horn sounds Fly that airspeed or the airspeed the instructor specifies

21 Performing Slow Flight
Add power as required to maintain selected altitude and speed Right rudder as required to center ball Pretend there’s a rod linking your right hand (throttle) and right foot (rudder) You may need a little left aileron to keep the wings level Don’t descend! If you do lose a little altitude, correct it immediately This will require (a lot) more power, more rudder, nose higher After correcting, take a little power and rudder out, pitch to maintain level flight

22 Level Turns in Slow Flight
Use shallow (10-15 degrees) bank and a slow roll rate At your speed, a level turn at moderate bank angles will result in a stall You’ll get a pretty good turn rate at your speed even with a shallow bank Use just a little more power to overcome extra drag while rolling / turning Rudder as required to maintain coordination Rolling left may require just easing up on the right rudder for proper coordination

23 Recovery from Slow Flight
Add full power, accelerate level and straight ahead Flaps to 20o at first, all the way up after accelerating a bit Trim! Gradually take out right rudder as you accelerate; keep ball centered Maneuver is done after you reach 100 KIAS/MPH

24 Why Practice Stalls? Inadvertent stalls are a very popular way to die
You must and will understand: What a stall is What it looks / feels / sounds / tastes/smells like How to avoid it And, most important, how to recover from it If you ever have a bad enough day that it becomes necessary Stall/Spin Accidents,

25 Why did all those people crash?
They didn’t recognize the impending stall When they did stall, they reacted with a panic response instead of a trained response Panic response is mediated from a different part of your brain than a trained response. It never does things by degrees Once the panic response took over, the thinking part of the brain never regained control

26 Panic Response to Stall
Brain, surprised by nose falling when it thinks it shouldn’t be, says “&*%^! Nose is falling! Better pull back on the yoke!” Yoke goes to the aft stop and stays there. Panicked brain will not move it from there as long as it’s panicked. If a wing lowers during stall, as is usual, brain says “&*%^! Wing is dropping! Better roll in the opposite direction!” Yoke turns full to the side and stays there. Will not move again as long as brain is panicked. This combination of controls is also known as “pro-spin” controls. Aircraft enters a spin.

27 Panic Response to Stall
Now the brain is really panicked; little chance of overcoming this with a trained response Either the aircraft hits the ground in a spin, or if recovery does get attempted, it’s interrupted by the surface of the planet Objectives of stall practice: Recognize impending stall in time to avoid it If that fails, train the panic response away; substitute a proper response

28 Stall Training Although excessive AOA and a stall can occur at any airspeed, attitude, or power setting, in a general aviation environment, it’s most likely to happen as a result of trying to fly too slowly These are the kinds of stalls we’ll concentrate on Good news: stall recovery techniques don’t change no matter what kind of stall you accomplish

29 Kinds of Stalls FAA’s Airplane Flying Handbook discusses these kinds of stalls: Power-on stall Power-off stall Secondary stall Accelerated stall Cross-control stall Elevator trim stall The first two listed are required maneuvers on your Private Pilot checkride, so we’ll concentrate on them

30 Stall Setup Minimum recovery altitude is 1500 AGL
What will that altitude be on your altimeter? Accomplish a descent check; select mixture – rich Clearing turns!

31 Power-on Stall Let’s pretend:
We just took off; we’re climbing out, full power, flaps up We set the pitch attitude too high, and failed to notice indications of impending stall When it finally does stall, we want to recover with minimum loss of altitude We’ll practice these both straight ahead and in shallow (20 ±10°) turns

32 Power-on Stall Entry After setup, throttle back, carb heat out, slow to a speed near takeoff speed Throttle and carb heat full in, raise nose to about 20-25o nose high Right rudder required as you push in the power Hold attitude, keep it coordinated, ignore indications of impending stall This will require constantly moving the yoke back and increasing right rudder as it slows If turning, opposite aileron will be required to keep bank angle from increasing as you slow Recover when nose falls due to stall

33 Stall Recovery Almost simultaneously, in order of importance:
Decrease angle of attack Level the wings Achieve maximum power Stop descent and begin to accelerate Continue to accelerate and recover

34 Decrease Angle of Attack
This means “decrease back pressure on the yoke” Pushing the yoke forward will result in a longer time to recover / more altitude lost in the recovery

35 Level the Wings Ailerons will probably still be effective, due to design of your aircraft Wings are designed to stall at the roots first, tips later, and ailerons are near the tips Rudder will be effective no matter what Use coordinated aileron and rudder to get wings level

36 Achieve Maximum Power You’re already there; check throttle full in
You’ll need a lot of right rudder to stay coordinated due to high RPM/low airspeed effects

37 Stop Descent and Accelerate
Reapply enough back pressure to maximize lift Stop descent; peek at VSI to confirm When descent is stopped, ease nose over to accelerate We want recovery to occur here

38 Accelerate and Clean Up
Accelerate level to slightly climbing You’ll need gradually less rudder as you accelerate For our purposes, maneuver is over when you reach 100 kts/MPH

39 Power-off Stall Let’s pretend:
We’re in the traffic pattern preparing to land, flaps down, throttle in idle We set the pitch attitude too high, and failed to notice indications of impending stall When it finally does stall, we want to recover with minimum loss of altitude We’ll practice these both straight ahead and in shallow (20 ±10°) turns

40 Power-off Stall Entry After setup, throttle back, carb heat out, extend flaps, slow to a speed near final approach speed Throttle to idle, raise nose higher than normal for a final approach Hold this abnormally high attitude, ignore indications of impending stall This will require constantly moving the yoke back; if turning, opposite aileron will be required to keep bank angle from increasing as you slow Recover when nose falls due to stall

41 Stall Recovery Almost simultaneously, in order of importance:
Decrease angle of attack Level the wings Achieve maximum power Stop descent and begin to accelerate Continue to accelerate and clean up flaps

42 Decrease Angle of Attack
This means “decrease back pressure on the yoke” Pushing the yoke forward will result in a longer time to recover / more altitude lost in the recovery

43 Level the Wings Ailerons will probably still be effective, due to design of your aircraft Wings are designed to stall at the roots first, tips later, and ailerons are near the tips Rudder will be effective no matter what Use coordinated aileron and rudder to get wings level

44 Achieve Maximum Power Firewall the throttle Push in carb heat
Technique: stick your left thumb out to catch the carb heat knob as you push the throttle in You’ll need a lot of right rudder to stay coordinated due to high RPM/low airspeed effects

45 Stop Descent and Accelerate
Reapply enough back pressure to maximize lift Stop descent; peek at VSI to confirm When descent is stopped, ease nose over to accelerate We want recovery to occur here

46 Accelerate and Clean Up
While level to slightly climbing, raise flaps Aircraft won’t accelerate well with flaps >20o, so bring them up to 20o right away Flaps full up after Vx You’ll need gradually less rudder as you accelerate For our purposes, maneuver is over when you reach 100 kts/MPH

47 Stall Recovery PTS standard for recovery:
Recognizes and recovers promptly after the stall occurs by simultaneously reducing the angle of attack, increasing power as appropriate, and leveling the wings to return to a straight-and-level flight attitude with a minimum loss of altitude appropriate for the airplane

48 Collision Avoidance Eyeballs are your best collision avoidance tool
Look around during your airwork maneuvers Back this up with monitoring the radio – BTV approach will call with any factor traffic he sees

51 Standard Traffic Pattern
45o to Downwind Downwind “Knapp State Traffic, Cessna 5943T, left downwind 17, Knapp State” Abeam touchdown point: CARB HEAT – ON “Landing Check Complete” On Final: Flaps – Landing setting Airspeed – 65 mph Assess glidepath Pitch for speed; Power for glidepath Base Prior to Downwind: Clear!

52 Final Approach Objective: arrive over the runway numbers
On final approach speed Over the runway centerline With the planned flap setting At a height suitable for the roundout/flare maneuver

53 Final Approach Flap settings Trim changes
First 200 extension – mostly extra lift Further extension – mostly extra drag Which is very helpful if you want to descend Trim changes As you slow, you’ll need to trim nose up. Until… Flaps more than 200 – get less flow over horizontal stabilizer, resulting in requirement for nose down trim

54 Final: Airspeed/Aimpoint
Adjust airspeed with nose position; “Pitch for speed” Want to go slower? Nose higher! Want to go faster? Nose lower!

55 Final: Airspeed/Aimpoint
Adjust aimpoint with power; “Power for glidepath” Too shallow? More power! Too steep? Less power! And don’t forget to stay on centerline

56 Common Error on Final It’s common to get the previous 2 slides backwards Student may just point the nose at the runway numbers, which results in nose low/higher speed And try to slow by pulling the throttle back Which doesn’t work because the nose is low All this results in a long, fast landing

57 Estimating Glidepath Aim for the runway numbers
Shouldn’t be so slow or steep that you lose sight of the runway numbers The point at which your flight path intersects the planet is the point which does not move up or down on your windscreen

58 Estimating Glidepath You only have one engine, so why not approach a little steep? That way, if the engine quits on final, you may not have to settle for landing in the trees just short of the runway For normal approaches, use the PAPI/VASI “on glidepath” indications as a lower limit until nearing flare The more headwind there is, the steeper your aircraft can approach

59 Roundout/Flare A slow, smooth transition from a normal approach attitude to a landing attitude Gradually round out the flightpath to one that is parallel with, and within a very few inches above, the runway Look ahead half- to three quarters the way down the runway Begin at about half a wingspan in altitude Start a little higher, flare more quickly if steep; lower, less quickly if shallow Once started, should be a continuous process until the airplane touches down on the ground This means the yoke should be slowly moving throughout the flare

60 Common Error in the Flare
As you descend below 100 feet, you’ll notice the ground seem to approach you rapidly Natural tendency is to pull the nose up to slow the rate at which the ground is approaching This gets you very slow, high above the runway Hold the nose down to maintain final approach airspeed until it’s time to flare At about half a wingspan in altitude

61 In the Flare Level off a few inches above the runway
Power to idle stop Align nose with runway with rudder Try to keep it from touching down It’ll eventually touch down anyway if the power is in idle But you’ll need to continually and slowly keep the yoke coming back as you decelerate

62 After Touchdown You’re not done flying!
Don’t just release all pressure on the yoke Ease the nosewheel to the runway Nosewheel steering available after nosewheel touches down Maintain runway centerline until slowed to taxi speed Brake as required

63 Really Bad Common Error
Never try to touch down at a particular place by releasing back pressure in the flare You will bounce, every time And this can lead to very disappointing results We’ll go over how to recover from a bounce in later lessons

64 Touch and Go Make sure there’s enough runway remaining!
While rolling down/correcting to the centerline: Flaps –up Either trim back to takeoff index or be prepared to pull back harder to rotate at proper speed Power and carb heat all the way in; hand remains on throttle Be prepared for left yawing tendency Rotate at proper speed

65 Remaining in Pattern Wind On crosswind Roll out with wind correction
Clear! Climb to pattern altitude Prepare to do Descent / Before Landing and Landing checklists Turn downwind Crosswind Wind Upwind leg: Maximum Power Normal climb speed (Nontowered) Climb straight ahead until 300 ft below pattern altitude Clear! Turn crosswind Upwind 300 feet low ref AC 90-66A 65

67 After Landing When clear of runway… 8ZD

68 After Landing When clear of runway… 43T
