5 Special Features of Operation
(a) Adjustable seat and rudder pedal mechanism: Normally, only the rear seat is adjustable by a lever on the starboard side of the cockpit. The rudder pedals may be adjusted by means of two knobs situated on the control box (in front of radio) in rear cockpit. After adjusting pedals ensure that pins are locked fully home.
(b) Aerobatics harness: The normal harness which is attached to the seat is a five piece, having a fifth strap to hold pilot between legs. In addition there is an emergency lap strap attached to the airframe to give pilots extra confidence during aerobatic maneuvers. Even if aerobatic maneuvers are not being performed, always fasten the entire harness and lap strap to avoid risk of fouling controls. Additionally, if the front cockpit is unoccupied, ensure that front harness and strap are secured.
(c) Fuel ON/OFF rod: This control is rather stiff to operate and has a short travel of 0.5 inches. Always double check that it is "ON" by pulling "OFF" and then pushing "ON".
(d) Use of brakes: The brakes are cable operated on to wheel brake drums. There is differential braking on each wheel operated by pressing rudder pedals to full extent of travel. There is also an independent parking brake. Always use differential brakes carefully and cautiously. Due to the cable mechanism, there is a tendency to "grab" if used violently, which could cause a nose-over. The parking brake should never be used for stopping in an emergency.
(e) Smoke system: Not fitted on G-BWEF.
(f) Starting engine: Engine cold - Prime engine from port side by pulling
ring and operating fuel pump levers. Suck in 8 times, wait for fuel to start
dripping, set throttle 0.5 inches and start on No. 2 mag to avoid back firing.
Engine hot - Do not prime or suck in. If engine fails to start blow out with
throttle open 12 times.
Engine warm - Prime engine and then blow out 12 times.
VI Special Features of Pre-flight Checks & Pilot Maintenance
(a) Overstressing: If the aircraft has been overstressed during aerobatic maneuvers, it should be grounded for engineer's clearance.
(b) Loose articles: Check very carefully for loose articles, particularly missing harness pins and clips. Before aerobatic flight, the hand fire extinguisher should be removed. There should be nothing in the luggage compartment. Check that the luggage compartment is properly secured.
(c) Front seat harness: Always check that this is properly secured and cannot foul the stick. If front cockpit cover is fitted, still check security of front cockpit before each flight. Make sure front mag switches are "ON".
(d) Oil level: Check oil level before each flight.
Note: A hot engine retains considerable quantities of oil in the engine.
(e) Controls: Check for full and free movement of all controls in the correct sense, without undue noise other than light rubbing of cables in their fiber guides. In particular check aileron control cables through transparent inspection covers where they pass round pulleys to aileron operating arms. Check for full and free movement of engine controls.
(f) Fuel cap: Check fuel cap for security and check for loose objects that may have been left on top of tank.
(g) Bracing wires: Check tension of bracing wires including centre section and tail plane bracing wires. If airplane has been overstressed there may be some slack.
(h) Fin post: Make special check on condition and security of the fin post.
(i) Engine bearers and top longerons: Make a special check on the condition and security of engine bearers and top longerons behind firewall.
(j) Propeller: During aerobatics, props are subject to high loads. Make a special check on condition of propeller for signs of cracks and for loose sheathing.
(k) Rudder pedals: Heavy footed pilots can bend rudder pedals in which case pedals will foul sides of cockpit. Check rudder pedals carefully and also check condition of rudder pedal toe- straps. Some pilots will not bother to use these in which case they will rapidly become worn and liable to break when most needed.
(l) Battery Always check that battery terminals are connected before flight to allow use of radio.
(m) Engine: A careful pre-flight of the engine can save endless trouble later. Check compressions, cracked induction manifold, exhaust pipes and gaskets, cracked baffles and cowlings etc. Also check for an excess amount of oil.
7 Post Flight
(a) Clean up: Always clean off aircraft after aerobatics, particularly under fuselage. The fabric and structure will last much longer if you do so.
(b) Battery: Disconnect battery terminal after use. Recharge if necessary.
