Introduction(Briefing:Straight and level)* * * Straight and Level flight * * *This lesson is all about ... Lift How you can control lift, “Straight and Level flight is great to get your head around how lift works.“along with..“It is easy to fly precisely if you know whats going to happen next.“ * * * How the Wings / Lift works * * *

Objectives(Briefing:Straight and level) To establish and maintain straight and level flight, at a constant AirspeedAltitudeDirectionAnd in balance To maintain straight and level flight at various airspeeds Regaining straight and level flight after a disturbance

Principles of Flight - The Four Forces(Briefing:Straight and level) Straight and Level is achieved... when Lift = Weightand Thrust = Drag And with a constantairspeedand direction Aircraft is in Equilibrium

Principles of Flight - The Four Forces - Couples(Briefing:Straight and level)The Four Forces dont act through the same point andcause a Lift/Weight and Thrust Drag couple. The Tail Planebalances the Lift/Weight couple Thrust / Drag CoupleAdd to the mix.Drag Position can changeLow Wing Aircraft etc. More thrust - Pitch updue extra airflowover the tail plane.

Principles of Flight - Lift(Briefing:Straight and level)Air over the top accelerates compared to air passing under the wing Lift = CL ½ ρ V² S CL- Wing Shape and Angle of Attack ½- Air Compressibleρ- Air Density - Speed through the Air (Squared) S- Area of the Wing * * * Lift = Angle of attack x Airspeed * * *

Principles of Flight - Performance(Briefing:Straight and level) * * * Power + Attitude = Performance * * * Power:2300 + Attitude:Normal = Performance(Straight and Level(S/L) @ 80-90kts) Power:1800 + Attitude:Higher = Performance(S/L @ 60Kts) Power:2500 + Attitude:Lower = Performance(S/L @ 110kts)

Airmanship etc...(Briefing:Straight and level)AirmanshipLookout + Situational Awareness training area boundaries, clear of cloud“I have control / you have control“Aeroplane ManagementSmooth throttle movementsMixture richCarb heat Human FactorsBlind spotsNew learning consistently reinforced(in later lessons) In IM SAFE what is I?I- Illness

Air Exercise - Maintaining (Briefing:Straight and level) The following scan makes maintaining straight and level easy... L- LookoutReference Point A- Attitudethe S/L attitude I- Instruments to confirm - not setAltimeter, Direction and RPM Other instruments and gauges,less frequently (Oil Pressure and temperature , Amp etc)( 90% )( 10% )

Air Exercise - Establishing or Regaining(Briefing:Straight and level) Also this is a handy “check list“to sort out what\'s happened and fix any issues. P- Power set for straight and level A- Attitude elevator set nose attitudeaileron wings level relative to horizonrudder in balance “stand on the ball“ T- Trim to relieve pressure hands off

Air Exercise - At Different Airspeeds(Briefing:Straight and level)Any changes in power must be balanced with rudderWhile moving rudder wings must be kept level Power + Attitude = Performance 2200 RPM S/L @ 80-90 knots 1800 RPM S/L @ 60 knots _
