Dear PPruners
The PofF Objectives have been updated on the JAA website, downloadable here JAR Objectives (http://www.jaa.nl/licensing/jar-fcl/jar-fcl_atpla_frame.html)
The Main Changes are listed below New questions will slowly trickle through.
Explanation of changes in issue 3 of the Learning Objectives for Principles of Flight, only the major changes are mentioned.
- Introduction added.
- Changed Bernoulli’s theorem into Bernoulli’s equation.
- Deleted the sentence requiring the theorem to be applied for a given speed and altitude.
- Added wing planform in section 081 01 01 05
- Added stable and unstable to centre of pressure movement with angle of attack.
- Added ground effect impact on lift and drag, also on induced angle of attack and on take-off and landing performance.
- Added altitude effects on stall speed including compressibility effects.
- Added effect of both forward and aft swept wings on stall and recovery characteristics.
- Stall and critical angle of attack are used to indicate the same value (top of the CL - á curve) Note that this a simplification of the
physical reality.
- Added what happens to static temperature and local speed of sound when passing a shock or expansion wave.
- Rewritten 081 05 08 03 about the factors influencing stabiliser setting.
- Included a rule to define limit and ultimate load factor and an explanation what happens if these values are exceeded.
- Relocated the rule to explain the relationship between VA and VS in a formula.
- Rewritten paragraph 081 06 03 02.
- Included a rule to describe the effects of engine/propeller torque.
- Expanded the write-up on effects of wind, mass and configuration on glide performance.
- Added a rule to explain the difference between a co-ordinated and uncoordinated turn.
- Expanded description on turn and slip indicator for asymmetric flight.
