Additional training to compliment this presentation will be available for CFIs who will conduct a Takeoff and Landing Clinic. FPMs may use this presentation to accomplish instructor training required for Approach and Landing “Core Group” members who attend CFI Workshop 6. Those attendees who volunteer will conduct “Landing Clinics” associated with the FAASTeam’s Approach and Landing Initiative. Additional training will be provided for those Core Group members.

Takeoff, Landing, and Low Altitude Maneuvering ~ Module #6 – Core Topic #11, Takeoff, Landing, and Low Altitude Maneuvering ~ Takeoff, approach and landing procedures Aircraft control in various Areas of Operation Identify strengths and weaknesses Let’s take a look as some statistics Encourage Safety through Awareness Are all of your students registered at FAASafety.gov?

Clinic Objectives Reduce the Risk of Accidents due to Improper Takeoffs, Landings and Loss of Aircraft Control. Evaluating Takeoff and Landing Procedures and Techniques. Encourage you to maintain your Takeoff and Landing skills through a Proficiency Program. (WINGS) Review recent General Aviation accident statistics for Takeoff and Landings to Increase Awareness and Safety. Encourage you to maintain your Takeoff and Landing skills through a proficiency program. (WINGS) Briefly discuss the WINGS Program and offer enrollment handout information. 4

Why Focus on Take-offs, Landings and Aircraft Control? The 2007 AOPA Nall report showed: 16.4% Of General Aviation Accidents occurred during the Take-Off phase of Flight. Statistics indicate 16.4% of GA accidents occur during the TAKEOFF phase of flight. This was a take off accident with a student pilot attempting a touch and go with a 20 kt. Tailwind. The pilot was unhurt. 5

Why Focus on Take-off and Landings? The 2007 AOPA Nall report showed: 40.3% Of accidents occurred during the Landing phase of Flight. Statistics indicate 40.3% of GA accidents occur during the LANDING phase of flight. The pilot of this P210 attempted to land going too fast. With a 17 knot tailwind the airplane was allowed to touchdown in the last 1/3 of the runway, went off the side of the runway, struck some lights, signs and fence, went into a ditch and came to rest on an access road just north of the airport. Interesting point, this pilot thought something like this would never happen to him. A rejected landing would have been the right choice. 6

Always keep the Aircraft on the Centerline of the Taxiway and Runway. Centerline Control Read the Slide and discuss the importance of centerline control. Discuss proper rudder control, nose steering and attention outside of the aircraft. Always keep the Aircraft on the Centerline of the Taxiway and Runway. 12

Normal Takeoff Review Read the Slide and discuss a normal takeoff. Emphasize centerline control, and use of recommended manufacturer speeds and proper use of performance charts. 13

Normal Take Off - Common Errors Failure to adequately clear the area prior to taxiing into position on the active runway. Abrupt use of the throttle. Failure to check engine instruments for signs of malfunction after applying takeoff power. Failure to anticipate the airplane’s left turning tendency on initial acceleration. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 14

Normal Take Off - Common Errors (continued) Overcorrecting for left turning tendency. Relying solely on the airspeed indicator rather than developed feel for indications of speed and airplane controllability during acceleration and lift-off. Failure to attain proper lift-off attitude. Inadequate compensation for torque/P-factor during initial climb resulting in a sideslip. Over-control of elevators during initial climb out. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 15

Crosswind Takeoff Review Talk about proper use of flight controls Rudder provides directional control until airborne Discuss How aileron controls drift once airborne Horizontal component of lift Transitioning to a crab once airborne and no further contact with ground is assured, Discuss various crosswind techniques i.e. rotate higher airspeed, lift up onto one wheel. 16

Application of Aileron Discuss proper technique for application of aileron in crosswind takeoff. 17

X-Wind Take Off - Common Errors Failure to adequately clear the area prior to taxiing onto the active runway. Using less than full aileron pressure into the wind initially on the takeoff roll. Mechanical use of aileron control rather than sensing the need for varying aileron control input through feel for the airplane. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 18

X-Wind Take Off - Common Errors (Continued) Premature lift-off resulting in side-skipping. Excessive aileron input in the latter stage of the takeoff roll resulting in a steep bank into the wind at lift-off. Inadequate drift correction after lift-off. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 19

Slow Flight or MCA Discuss the purpose of flight at MCA? (control feel, sloppiness at slow speeds) 20

What’s going on with drag vs airspeed? Excellent insight from Todd Burk, FAASTeam Program Manager, Central Region “I often compare this graph to a person that has financial stability or "money in the bank". If you spend more than you make then you will go bankrupt. How do you make money? With more thrust and a reduced angle of attack. How do you spend money? By reducing the power and increasing the angle of attack i.e. beginning the landing flare. The idea is to be out of altitude and money at the same time, not one before the other. If you get that sinking feeling and you haven't contacted the ground yet, you need to start adding money to the bank before you go bankrupt. By the same token, if you can add back pressure and initiate a climb,before you touch down, you have too much money in the bank. (Exchange of energy for altitude)”

FAA-H-8083-3A Airplane Flying Handbook Definition The Airplane Flying Handbook FAA-H-8083-3A Defines Minimum Controllable airspeed as a speed at which any further increase in angle of attack or load factor, or reduction in power will cause an immediate stall. FAA-H-8083-3A Airplane Flying Handbook 22

Slow Flight - Common Errors Failure to adequately clear the area. Inadequate back-elevator pressure as power is reduced, resulting in altitude loss. Excessive back-elevator pressure as power is reduced, resulting in a climb, followed by a rapid reduction in airspeed and “mushing.” Inadequate compensation for adverse yaw during turns. Read the Slide and discuss. Inadequate compensation for adverse yaw or improper use of rudder (coordination) can result in loss of control and spins in the event of a stall. FAA-H-8083-3A Airplane Flying Handbook 23

Slow Flight - Common Errors (Continued) Fixation on the airspeed indicator. Failure to anticipate changes in lift as flaps are extended or retracted. Inadequate power management. Inability to adequately divide attention between airplane control and orientation. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 24

FAA-H-8083-3A Airplane Flying Handbook Steep Turns Talk through a steep turn Clearing the area Topics Adverse Yaw Coordination Need for additional power due to load factor and induced drag Stall speed increase due to load factor Smooth coordinated (rudder) Roll in and roll out FAA-H-8083-3A Airplane Flying Handbook 25

Steep Turns - Common Errors Failure to adequately clear the area. Excessive pitch change during entry or recovery. Attempts to start recovery prematurely. Failure to stop the turn on a precise heading. Excessive rudder during recovery, resulting in skidding. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 26

Steep Turns - Common Errors (continued) Inadequate power management. Inadequate airspeed control. Poor coordination. Gaining altitude in right turns and/or losing altitude in left turns. Failure to maintain constant bank angle. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 27

Steep Turns - Common Errors (continued) Disorientation. Attempting to perform the maneuver by instrument reference rather than visual reference. Failure to scan for other traffic during the maneuver. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 28

Power Off Stall Recovery 1. Reduce Angle of Attack Recognition Power Off Stall Recovery 1. Reduce Angle of Attack 2. Add Power 3. Keep Wings Level 4. Use adequate Rudder Read the Slide and discuss 29

Stall Recognition Power On Stall Recovery 1. Reduce Angle of Attack 2. Keep Wings Level 3. Use adequate Rudder Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 30

FAA-H-8083-3A Airplane Flying Handbook Stabilized Approach Airspeed control- Elevator Rate/ angle of descent controlled by Power Emphasize that a stabilized approach consists of : airplane properly configured (gear, flaps, and power) , Maintaining extended centerline on final and desired approach speed for the weight* ( 3-5 degree glide path to a predetermined touchdown point ( within the first 1/3 of the runway). FAA-H-8083-3A Airplane Flying Handbook 31

Gross Wt Compensation 80 kts @ Gross Divide actual wt by gross wt to get % of gross (2000 by 2500 = 80%) Subtract % of gross from 100% (100%-80%= 20%) Divide % by 2 (20% by 2 = 10%) Reduce your app spd by this % ( 10% of 80 kts = 8 kts. 80 – 8 = 72 kts) Actual Speed for Approach…..72 kts 32

Landing - Common Errors Failure to allow enough room on final to set up the approach, necessitating an overly steep approach and high sink rate. Un-stabilized approach. Undue delay in initiating glide path corrections. Too low an airspeed on final resulting in inability to flare properly and landing hard. Read the Slide and Discuss Emphasize the need for total airspeed control. FAA-H-8083-3A Airplane Flying Handbook 33

Landing - Common Errors (continued) Too high an airspeed resulting in floating on round out. Prematurely reducing power to idle on round out resulting in hard landing. Touchdown with excessive airspeed. Excessive and/or unnecessary braking after touchdown. Failure to maintain directional control. Read the Slide and Discuss FAA-H-8083-3A Airplane Flying Handbook 34

Crosswind Landings This is one of the most common areas of difficulty for most pilots There are two basic techniques, the crabbing method and wing low or “side slip” method. Really the crabbing method is more suited to large aircraft. They have a lot more mass and when the rudder is used to take the crab out it takes more time for the aircraft to start moving off centerline. Whereas with a light aircraft it will move off the centerline almost immediately. The wing low or sideslip method is almost always a better technique. As the Speed decreases so does the effectiveness of the flight controls. Many pilots also fail to continue to add more aileron control into the wind as the aircraft slows down on roll out. This can contribute to a loss of directional control. Do you use the wind sock? Think about partial or no flap landing. Know your crosswind performance / limitations. 35

Crosswind Landings Common Errors Attempting to land in crosswinds that exceed the airplane’s maximum demonstrated crosswind component. Inadequate compensation for wind drift on the turn from base leg to final approach, resulting in undershooting or overshooting. Inadequate compensation for wind drift on final approach. Unstabilized approach. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 36

Crosswind Landings Common Errors (continued) Failure to compensate for increased drag during sideslip resulting in excessive sink rate and/or too low an airspeed. Touchdown while drifting. Excessive airspeed on touchdown. Failure to apply appropriate flight control inputs during rollout. Read the Slide and discuss Be sure and emphasize as the aircraft slows down you should continue to add more aileron into the wind so that at the end of the roll out, you have full aileron deflection into the wind. FAA-H-8083-3A Airplane Flying Handbook 37

Crosswind Landings Common Errors (continued) Failure to maintain direction control on rollout. Excessive braking. Read the Slide and discuss FAA-H-8083-3A Airplane Flying Handbook 38

Go Around From Rejected Landing Read the Slide and discuss YOU NEED TO MAINTAIN PROFICIENCY IN THIS MANEUVER. If it gets outside of your abilities or the capabilities of the airplane, then GO AROUND! FAA-H-8083-3A Airplane Flying Handbook 39

Go Around Common Errors Pitch attitude increased excessively resulting in a stall Applying only partial power Failure to reconfigure the aircraft (gear and Flaps) for climb Retracting the flaps too quickly Elevator trim (excessive forward pressures) Read the Slide and discuss Don’t you dare do this too late!!! Make a decision to go around! In a retractable gear airplane, leave the gear alone if you do not need the climb performance. Too many people have executed a go around only to follow it up with a gear-up landing. FAA-H-8083-3A Airplane Flying Handbook 40

FAASTeam CFI Workshop #6 Take a Break! Break for 10 minutes, if longer it can not count as part of the Core Topic time.

Core Topic 12 Aircraft Operational Limitations ? Why do we care? Short discussion

Nice place, seemed a little short when we landed! Continue

1850’, grass, it’s hot, and the tanks are pretty full …. Continue

... only three of us and there’s a river beyond the trees .... Continue

I think we’ll be ok to try a takeoff ………. Continue

We’re not accelerating very well … I can’t stop now! …. Continue

They didn’t consider the potential problems for takeoff before they landed there. They didn’t consider options when they realized the takeoff might be difficult. They didn’t confirm that the airplane’s performance capabilities would allow a safe takeoff, or not. They didn’t plan for a point at which to abort the takeoff if acceleration was too slow. The aircraft owner, his teenage son, and a CFI did all drown in the wreckage. Continue

Take your pick, each one defines an end to options: limitation - restriction: a principle that limits the extent of something; limitation - the quality of being limited or restricted; limitation - limit: the greatest amount of something that is possible or allowed; limitation - (law) a time period after which suits cannot be brought; limitation - an act of limiting or restricting (as by regulation) Read and continue

What do you want your students to do? Will they know what options exist? Is “I think we can” good enough for you? Where is the performance information a pilot needs in order to be sure? What warnings are there to tell us we’re at or near a limit? Read and continue

What do you want your students to do? Make decisions based on knowledge and facts. Will they know what options exist? Give them problems to solve during their training. Is “I think we can” good enough for you? Give them the opportunity to evaluate conditions. Where is the performance information a pilot needs in order to be sure? Show them the Pilot Operation Handbook and performance charts, insist that they are used. What warnings are there to tell us we’re at or near a limit? Teach them to use situational awareness in all aspects of preflight planning and in flight Discussion

Yes, take the time …. …..get all that stuff out, review it yourself and then share your knowledge. Continue

Emphasize the importance of aircraft performance planning! Demonstrate the aircraft’s limited performance at reduced power to simulate the effect of temperature and pressure altitude. Read and discuss

Full can be a beautiful thing! But, when it comes to loading an airplane …….. Continue Full can exceed the weight and/or CG limits!

Weight can be a limitation. depending on runway length, Weight can be a limitation depending on runway length, temperature, runway condition, and density altitude. What to do? Less fuel? Maybe, what’s the weather doing? Fewer passengers? Could you leave someone behind? Different runway? Perhaps the opposite direction? Wait until the temperature decreases? Can you spare the time it takes to stay alive? Discussion

Does the weight of whatever you put into the aircraft remain constant? What happens when you bank for a turn ………. and maintain your altitude ……………………… then increase your bank angle to 45 ….. 60 degrees ? In which Category was your airplane Certificated, how many Gs are legal? 100 pounds at 3 Gs becomes 300 pounds ……. Is that a limitation? How about bags and cargo? Discussion

After you have convinced your students that you can’t always fill every space in the aircraft, fill the tanks, and not exceed several of its operational limitations ………… Remind them that the Certificated limits are based on the performance of a new aircraft, at the exact weight, at a density altitude equal to sea level and standard temperature, demonstrated by …... Discuss

Make sure your students know that the tables and calculations available in the Pilots Operating Handbook are based on pressure/density altitude. The International Standards Association (ISA) has defined a Standard Atmosphere as: Sea Level Barometric Pressure of 29.92 inches of Mercury (in. Hg) Sea Level Temperature of 15° Celsius (15° C or 59° F) Relative humidity of 0 % Standard temperature lapse rate of 2° C per 1000 feet altitude Standard pressure lapse rate of 1 in. Hg per 1000 feet altitude A standard decrease in density as altitude increases Read through discuss as necessary

nonstandard temperature. Pressure Altitude adjusts for pressure difference between your air and standard atmosphere. The question is “What would your altimeter read if you were in a standard atmosphere at your current actual altitude?” This altitude is called PRESSURE ALTITUDE. Density Altitude uses Pressure Altitude as a basis, and adds in a correction factor for nonstandard temperature. Read and continue

Even when you take care of all the other details, if you haven’t considered C of G ….. You may become a TEST PILOT! Discuss the possibility of unsatisfactory or unsafe handling characteristics

What should you expect if … the airplane is tail heavy, even when you are within CG limits or, the airplane is nose heavy; Flight Control effectiveness? During takeoff? During Landing? During a Stall? During Spin Recovery? Encourage discussion

Any limitations to consider before Landing? Continue

Pilot skills, aircraft limits, and the runway? Continue

A little wind, a little too fast, no margin for error! Does this happen? Yes, all the time. Combination of an airplane’s limitations not recognized by a pilot with limited experience.

Again, Teach your students to consider options prior to takeoff, operations during flight, and landing. Teach them to consider the limitations of the aircraft and their own limitations based on their knowledge and experience. Stress the importance of having a thought process for all aspects of aviation

The airplane couldn’t do it ……… do you remember why? Continue

The aircraft’s performance capability, the airspeed, and altitude from which the maneuver was initiated combined did not allow the pilot to recover from the maneuver. Same thing here, physics will interrupt flight! Other examples you can think of?
