Emergency Approach And Landing

Emergency Approach And Landing

Objective: The student will be introduced to emergency approach and landing while covering what is a glide, drag curves, and the steps that should be taken so complete an emergency approach and landing. 

Completion Standards: The student will be able to explain what a glide is as well as how it is used in an emergency approach to a landing. The student will also be able to explain the steps to be taken to complete an emergency approach and landing safely.

Introduction: 

(Attention Getter) : Like a glider or paper airplane and safely landing without an engine.

Motivation: We will be discussing what and emergency approach and landing is and why its important to know.

Overview:

Engine failure

Glide

Drag curves

Emergency approach and landing (simulated) steps


Content:

Review what lift is and relation to weight along with thrust and drag

What happens when the engine fails?

Plane still flies

Falls slowly

What is a glide?

In glides, a portion of the weight vector is directed along the forward flight path and, therefore, acts as thrust. In other words, any time the flight path of the aircraft is not horizontal, lift, weight, thrust, and drag vectors must each be broken down into two components.

Drag curves

L/D ratio

Lift generated by a wing or airfoil compared to its drag

In unaccelerated flight with the lift and drag data steady, the proportions of the coefficient of lift (CL) and coefficient of drag (CD) can be calculated for specific AOA

Insert Drag Curve

Explain how we get these numbers for Vx and Vy/ best glide

Best glide- 68 Knots per PIM

Emergency approach to a landing (simulated)

Explain it’s like a traffic pattern/ draw it out

Steps for maneuver Go through Each step with student in detail 

  1. Once engine has slowed/ stopped (simulated).

    1. Pitch for best glide speed 68 Kn. 

    2. Select a suitable field to land at. Google satalite

    3. What way the wind is from

      1. Helps determine landing direction

  2. Fly toward selected field/ circle the field

    1. Conduct emergency checklist

    2. Go through Checklist with student ABC Check list

  3. At 1500 feet enter traffic pattern

    1. Go to high key point

      1.  Around 1000 feet

    2. Go to low key point/ base leg

      1. Around 500 feet

    3. Set up for landing, using flaps

  4. Notes to using flaps and the landing

    1. When you are high

    2. What you put in you cannot take out

Common errors

  1. Improper airspeed/ glide speed

  2. Poor judgment on landing area

    1. Obstacles

    2. Landing direction

  3. Failure to determine wind speed and direction

  4. Traffic pattern suitable to situation

  5. Completing emergency check list

  6. Overshooting or under shooting landing path


Conclusion

Went over what a glide is and how it is determined

Went over drag curve

Went over emergency checklist

Went over the steps to an approach


(Questions to assess student)

How is our best glide speed found

What is a drag curve?

What are the steps to completing an emergency approach and landing?
