Objective: To learn and practice the procedures for landing in a slip.

Content: Reasons for a slip, slipping attitude, airspeed and wind drift (ground track) control, touchdown

Equipment:
Airworthy aircraft. PTS. Model airplane

Schedule:
Ground lesson: 10 minutes
Instructor demonstration: 5 minutes
Student practice: 20 minutes (in pattern/practice area)
Postflight feedback: 5 minutes

Instructor:
Preflight: (see lesson plan) motivate, explain, have student be an armchair pilot, list common errors, discuss.
In flight: Demonstrate forward slip to landing while talking through it. Coach and encourage student.
Postflight: Give feedback and suggestions.

Student:
Preflight: Attend to explanation, be an armchair pilot, answer questions
In flight: Perform forward slips after demonstration
Postflight: Ask questions.

Completion Standards:
Maintain ground track with runway centerline and airspeed for minimum float. Lands within 400 feet of specified point. Maintains crosswind correction and directional control. Completes appropriate checklist.

Review: Crosswind landing, short-field landing, go-around
Objective: Reasons for a slip, slipping attitude, airspeed and wind drift (ground track) control, touchdown
Materials: Model airplane

INTRODUCTION: Attention/motivation: (1 minute)
To land in an emergency, or on to a field with obstructions, there is a maneuvering technique that allows a sharp descent angle without an increase in airspeed: a slip. (Note that the AFH says, "A pilot should not use a slip to lose altitude because of poor planning" p. 7-8) There are two kinds of slip: a forward slip, and a sideslip. We use sideslips normally counter the wind during a crosswind landing, putting one main wheel down before the other. The forward slip looks different, as you will see.

DEVELOPMENT: Overview and explanation: (2 minutes)
Procedure:
1. Clear the area
2. Lower one wing
3. At the same time, apply opposite rudder to keep the plane from turning
4. Reduce and control power: hand on throttle
5. Use elevator pressure to maintain a normal approach speed. Trim if necessary
6. Maintain a stabilized slip
7. Discontinue the slip when a proper altitude is achieved
8. Round out, maintain directional control, make a stable landing and apply brakes
9. Checklist
Airspeed is very, very important. Danger: what's going to happen if you stall the plane while in a slip?
Some aircraft POHs say not to do a forward slip while flaps are in.

Armchair piloting: (2 minutes)
Student simulates proper technique for a slip to landing, including keeping the hand on the imaginary throttle.

Common errors: (2 minutes)
Improper use of landing performance data and limitations
Improper sequence of configuration
Approached not established in a stable way
Removal of hand from throttle
Improper transition from slip to touchdown
Poor directional control before/after touchdown
Improper braking

Oral evaluation/quiz and discussion questions: (2 minutes)
Q: What is a forward slip used for?
Q: For your aircraft, what does the POH say about slips and flaps?
Q: What airspeed should you use while slipping? How do you control it?
Q: When should you round out from a slip?
