2) Know the general characteristics of:
A heavy bomber, a transport aircraft, an airliner, a fighter aircraft (not jet-propelled), and a jet-propelled aircraft.
3) Recognise from silhouettes and photographs 20 aircraft, and of these name and recognize 10 normally seen flying over her part of the country.
AIR CREW
Awarded to a Ranger who holds the Leading Air Ranger Certificate and has spent three hours flying as a passenger or a pupil, and shown that she has kept her eyes open and thoroughly understood the interior layout, control, performance and emergency facilities of the aircraft in which she has flown, and is capable of helping the pilot, if need be, with auxiliary services such as lowering the undercarriage or flaps or changing over fuel cocks.
AIR MECHANIC
1) Understand the elementary principles of an internal combustion engine.
2) Know the difference between an air-cooled and a liquid-cooled aero engine, and be able to explain the functions of the following: fuel system, oil system, carburetor, ignition system, starting magneto, and an impulse started.
3) Understand the use of sparking plugs and be able to test, remove, clean and replace them.
4) Know the precautions necessary when refueling an aircraft.
5) Understand the movement of the control surfaces and trimming tabs of an aircraft or glider, and be able to check each for full and correct movement.
6) Be able to detect corrosion, and apply treatment (including preventive treatment for it.
7) Be able to soft-solder.
GLIDER CREW
1) Know the materials from which a normal glider is constructed, and the form of the construction.
2) Know how to rig at least one type of glider, and show that she is capable of carrying out an inspection of safety before flight.
3) Know three methods as to how gliders may be launched, have assisted in at least one launching, and understand the principles and practice of winch operation.
4) Demonstrate how to inspect and repair a launching cable by splicing and knotting. Be able to explain he purpose of weak links and be able to make them.
5) Demonstrate the handling of a glider on the ground, how to picket it, where it should e placed for launching, and what signals to give tot he winch driver or tug pilot.
6) Show ability to repair a small hole in either fabric or plywood skin of any part of the glider.
METEOROLOGY
1) Describe the general characteristics associated with: a warm front, a cold front, a high-pressure area, a low-pressure area.
2) Classify and describe the appearance of the main types of cloud and be able to explain which types of cloud are useful to a sailplane pilot, and why.
3) Be able to explain what is meant by the following: Buy Ballot Law, Isobar, geostrophic, dew point, tropopause.
4) Be able to explain the use of the following: a wet-and-dry bulb thermometer, an anemometer, a barometer.
5) Interpret in detail a standard weather map and make a route forecast for an imaginary flight at a given time.
6) Describe the work of the International Meteorological Organisation, its purpose, and the methods used for carrying out its work.
NAVIGATION
1) Be able to explain what is meant by the following: latitude, longitude, cardinal points, quadrantal points, great circle, rhumb line, small circle.
2) Understand the elementary principles of map-projection and interpret in detail an aviation map.
3) Understand the principles and use of a magnetic compass and explain the following: magnetic dip, northerly turning error, variation and deviation.
4) Understand the use of the triangle of velocities and explain the following: air speed, ground speed, track, course, wind-velocity, drift, bearing.
5) Be able to work out a course on a navigational computer, given the track required, the wind-velocity and the true airspeed, and then prepare a route-card for the fight, flying by map-reading.
THEORY OF FLIGHT
1) Describe the airflow over the wing of an aircraft and explain the meaning of: down-wash, centre of pressure, aspect ratio, angle of attack, stalling angle.
2) Analyse the drag on an aeroplane - wind drag, parasite drag, and cooling-drag - and explain how the drag can be reduced.
3) Explain how the stalling speed may be reduced by the use of slots and/or flaps.
4) Understand what stability means in the three planes, and how it is achieved.
5) Understand the meaning of: di-hedral yawing, rolling, pitching, sideslip, aileron drag, slip-stream, and mass balance.
6) Explain the use of trimming devices.
