Original Pilot's Notes for WWI Replica Aircraft used in the movie The Blue MaxEdited by Randy Wilson I have not had time to reformat these notes for HTML, so please excuse the preformatted text, which was from an old word processor. I have added page numbers at the top of each original page, to make the table of contents a little more usable. My original editor's notes are in [square brackets], and references to the F.A.C. mean the Fighting Air Command, the organization which purchased the aircraft in the early 1980s and brought them to Hartlee Field, near Denton, Texas. I flew all of the aircraft that were eventually made "flyable".

They appear to be notes used to familiarize the pilots with the general operation and characteristics of the WWI replica aircraft. No author's name is listed but they may have been written by Derek Pigott. Our photocopy of the original typewritten notes is not very clear is some places and contains a number of typographical, syntax and spelling errors, as though it were prepared in hast with little chance for editing. The copy of the notes which follows has been retyped and significant errors corrected to make the notes more readable. My notes and comments are enclosed in brackets []. As the filming of The Blue Max took place in Ireland and used mainly British pilots and crews, the British spellings for some words have not been changed. Also, the gallons mentioned are assumed to be Imperial gallons. The Fokker D.VII replicas are not mentioned in these notes, however, a complete set of Construction Notes and Instructions For Use of the Fokker D.VII/65, written by the builders, is reproduced and available separately from the F.A.C. The Fighting Air Command currently owns ten of the aircraft used in The Blue Max, three Fokker D.VIIs, two Pfalz D.IIIs, four S.E.5a's (about 85% scale) and the Caudron 277 "Luciole" used as both a British and German two-seater in the movie. Two of the D.VIIs and one of the D.IIIs is currently flying and we hope to have the other two of these types airworthy soon. The S.E.5a's are in need of considerable work before they can fly, as only one engine and no propellers were obtained. The Caudron sustained major damage while in storage in Ireland when a hangar collaped on it, and it is in need of major rebuilding. Anyone wishing to contribute either money or experienced labor to these projects may contact me or the F.A.C. at the address shown below. Randy Wilson Fighting Air Command P.O. Box 802402 Dallas, Texas 75380 Page 2 ---------- General Notes on Replica Aircraft Most of these aircraft are on a Permit to Fly and have not had extensive test flying. They should therefore be flown with a certain amount of caution - particularly at high speeds and in turbulent conditions and especially dog fights. The forward position of the main wheels makes them particularly prone to swinging and special care is needed to keep straight in light winds and particularly on hard surfaces and runways. The tail skid loads are very high and rough ground and sharp edges of concrete should be avoided while taxying. Risk of damage crossing rough ground can be reduced by keeping the stick hard forward and using power to take the weight off the tail skid. There will be occasions when help will be needed to swing the aircraft while taxying. When necessary, stop and wait for help, or call for help on the radio. Use caution when taxying as a slight downhill or following wind may make it impossible to stop without switching off the engine. The engine tick over speed is critical and if wrong must be adjusted to reduce the risk of overshooting on landing or alternatively stopping the propeller in flight. Avoid unnecessary slow running as it results in oiling up the plugs. Engine starting accidents can be avoided by insisting that the propeller is always treated as live. Before turning any propeller, check that the switches are off and that the throttle is closed. Use only qualified propeller swingers. The undercarriages are sprung by bungee (shockcord) and this should be checked for damage before flight. If the bungee fails, the wire safety strop prevents the axle collapsing, but the aircraft is left in a wing down attitude and is unserviceable for further flying. With the exception of the D7, the fuel gages are non existent or unreliable and the limited fuel capacity makes it essential to have full fuel tanks for every flight. The Slingsby SE5 replicas will have flown a very minimum of hours and any signs of damage or unusual handling must be reported to Johnny Maher and Derek Pigott immediately. [These are about 85% scale replicas, not to be confused with the full scale Miles replicas. Four of the Slingsby SE5's are owned by the F.A.C.] Most of the aircraft have rather unconventional sideslipping characteristics which should be explored at height by each pilot. Please note any snags on the Form 101 or equivalent so that they can be put right as soon as possible. Suggestions are welcome. Page 3 ---------- Notes on Flying the Miles / SE5a Replicas [These aircraft were not acquired by the F.A.C. and are believed to have been full scale replicas. We were told that both crashed during filming or shortly after.] These SE5 replicas have simple handling characteristics and ample power. Starting Chocks in place and fire extinguishers at hand. Fuel cock on (Push on), throttle closed, switches off. Pull ring at top, right hand side of instrument panel until ground crew confirm that fuel drips out of the carburetor overflow pipe below the cowling. Prime with one to two full strokes of the Kigas primer while the propeller is turned over. Do not over prime or you may start an intake fire. Throttle set at half an inch open, both switches on and press the starter button. After starting, check for normal oil pressure and warm up at 1000 - 1200 r.p.m. for 5 minutes when cold. (Oil temperature may not register in this time) Stick hard back during run up. Check for a dead cut, normal static revs 2100. Select hot air (Turn T handle and pull) and check that the engine note changes or the r.p.m. drops indicating that the control is serviceable. Return the cold air. The acceptable magneto drop is 100 r.p.m. Check the oil pressure is normal and the slow running 6 - 700 r.p.m. Taxying There are no wheel brakes but the steerable tail skid gives very satisfactory steering in most conditions on grass. Use extreme caution on concrete as the tailskid gives no control and the aircraft is heavy and cannot be stopped quickly. Care is needed to prevent a ground loop after landing on concrete. Vital Actions Normal pre take off and landing drills should be used. However, there are no trimmers, pitch control, mixture or flap. The fuel gauge tap on the instrument panel should be kept in the off position except then using the gauge as otherwise air could enter the fuel lines and cause an air lock during steep attitudes. The gauge is of little value as slight changes in attitude upset the reading. Page 4 ---------- Take off & Climb There is no significant tendency to swing but the stick position on take off and in flight is further forward than on other aircraft. The unstick speed is about 60 knots and the climbing speed is 70 - 75 knots at about half an inch less than full throttle. The attitude and view ahead in the climb is similar to that when taxying. There is no tendency to overheat at anytime. Handling Apart from the heavy ailerons, the flying controls are very satisfactory. With no elevation trimmer, the aircraft will not be in trim except at one power setting and speed and this will vary with pilot weight and the fuel state. The aircraft is aerobatic with full fuel tanks. The stall is docile and occurs at about 60 knots. The spin recovery is less than 1 turn provided that the stick is moved steadily forward after full opposite rudder has been applied. The never exceed speed (marked with a red line) is 120 knots. A satisfactory speed for a loop is 100 - 110 knots. Rolls are not recommended because of the poor rate of roll and high stick forces required. Endurance The limited endurance and poor fuel gauge advisable for the pilot is to satisfy himself that the tank is full before flight. The tank holds 20 gallons. In cruising flight, the endurance is about 1 hour 40 minutes but flights involving formation or dog fights should be limited to 1 hour as the fuel consumption is much greater for this type of flying. Approach and Landing Hot air should be selected in moist conditions or while gliding or while descending at low power settings. Minimum glide approach speed 75 knots. Powered approach speed 65 - 70 knots. Note: Below 75 knots, quite large amounts of power are required to correct for undershooting. The gliding attitude is deceptively steep and care must be taken to avoid getting too slow during the final stages of the approach. A curved approach or side slip improves the pilots view. Normal 3 point and wheel landings are easily carried out. Side slipping is effective but should be practiced with ample height until the pilot is familiar with the unusual control loads during the recovery. Page 5 ---------- Running down and stopping The slow running cut out is the red toggle on the right hand side of the instrument panel. Between flight the fuel cock can be left on and this prevents vapour locks in the system. ---------- Notes on Flying the Bianchi Pfalz [This aircraft is currently owned by the F.A.C. and is painted silver with the markings of Werner Voss. I do not know why it is refered to as the "Bianchi" Pfalz, unless that was the man's name at Personal Plane Services who built it.] This replica is of rugged construction and docile handling. Special care should be taken to avoid high speed in steep dives as the stick forces are rather high for recovery. The present permit does not allow aerobatics. Starting Fuel cock on (Pushed forward with the red clip engaged). The carburetor is flooded by the ground crew pulling the ring and working the fuel pump lever by hand until fuel drips from the overflow pipe below the cowling. Switch both switches on for starting. A normal run up procedure should be used. At full throttle the static revs. should be 1950 r.p.m. and the permissible mag. drop is 75 r.p.m. Slow running should be 600 - 650 r.p.m. Taxying The steerable tail skid gives excellent steering on grass. Avoid landing on runways as the forward position of the undercarriage makes it liable to ground loop unless the tail skid can grip the surface. Vital Actions There is no fuel gauge or carburetor heat control. The elevator trim is best moved right forward to help reduce the high stick forces needed to get the tail up on take off. Take off and climb The take off is short and simple, but the stick force required to lift the tail is very high. The unstick speed is about 40 knots and the normal climb at full throttle is 50-55 knots. The engine cooling is satisfactory. Page 6 ---------- Handling All the controls are rather heavy. The stall is docile and occurs at about 32 knots. The spin recovery is good, but the rudder forces required to apply full opposite rudder are very high. The never exceed speed is 104 knots. Steep dives should be avoided as the recovery height and stick forces involved are rather large. Loops, chandelles and stall turns are satisfactory but the low rate of roll prevent any rolling manoeuver. The present permit does not permit aerobatics. Endurance The upright Gipsy Major engine uses about 7 - 8 gallons per hour cruising and the fuel capacity is 18 gallons giving an endurance of about 2 hours cruising and 1 1/4 hours safe for formation or dog fights. Approach & Landing Glide approaches 50 - 55 knots. Powered approaches 40 - 45 knots in smooth conditions. Note: as speed is reduced a nose up trim change occurs and care is needed to avoid ending up too slow. 3 point landings are simple. Use caution until familiar with the side slipping characteristics as the rudder loads change considerably with varying angles of slip. Stopping Allow the engine to cool down at about 800 r.p.m. before switching off and opening the throttle wide. If the engine continues to fire, close the throttle, switch on and allow it to run again for a short time to cool down. Leave the fuel cock on unless the aircraft is being returned to the hangar. ---------- Notes on Flying the Fokker Triplanes [Neither of the Triplanes used in the movie was purchased by the F.A.C. Another Triplane, however, is currently on loan to the collection.] These replicas are soundly designed and built, but have a poor rate of climb. The visibility during taxying, take off and landing is very poor. The control response and handling is interesting and unique. Starting The cockpit layouts in the two aircraft have important differences. Both have fuel and oil cocks. The fuel and oil cocks should be switched off between flights to prevent flooding of the lower cylinders. Both switches can be used for starting. Page 7 ---------- Hand swinging of these engines can be tricky and the ground over will probably call for the switches off between each movement of the propeller. The engine should be thoroughly warmed up before run up or it may run rough at full throttle. The carburetor heat is permanently but relies on the engine being well warmed. The correct static r.p.m. for each machine is noted on the instrument panel. If this is not obtained the cause is usually both plugs in one cylinder are not firing. The engine will then appear to run normally with little or no mag. drop but the faulty cylinder will be cold to the touch. The take off and climb can be extremely marginal unless normal power is available. The maximum mag. drop allowable is 50 - 75 r.p.m. Note that the throttle is spring loaded to open itself and special care must be taken to tighten the friction nut if pilots are changed with the engine running. The steerable tail skid is not very effective. Vital Actions No trimmer, mixture control or fuel gauge is fitted. Take off & Climb The rudder is powerful and without feel. Care is required not to over control at first. Raise the tail as soon as possible to see over the nose. This also increases the load on the wheels and reduces the risk of tipping a wing tip. The unstick speed is about 80 km/hr and when possible it is best to fly level to gain the normal climbing speed 110 km/hr. The visibility ahead is very poor at this stage and pilots are advised to have a plan of action in event of engine failure. A very quick transition into a steep glide would be required to avoid stalling. Use full throttle for all climbing but do not make prolonged climbs at less than 110 km/hr. Handling Then handling is unique and resembles a Link Trainer. There is very little feel in the aileron or rudder and a high degree of skill is needed to turn and manoeuver accurately. Keep both feet firmly on the rudder to prevent the aircraft yawing at speed. The stall is very gentle with little or no tendency to drop a wing. The indicated stalling speed is less than 60 km/hr because of the large position error at low speeds. The spin is hard to induce but is rapid with a good recovery. A state of semi- stalled, low speed spiral occurs if the aircraft does not enter a full spin. The high drag restricts the speed making this a safer alternative to spinning for film purposes. Page 8 ---------- The aircraft has been looped and rolled but the present permit to fly does not allow these maneuvers. The never exceed speed is 210 km/hr. The engine does not exceed its limitations at full throttle at this speed. Endurance The two tanks hold 21 gallons and the normal fuel consumption is about 6 - 8 gals. per hour, giving about 2 1/2 hrs. at cruising speed or about 1 1/2 hrs. for formation or dog fighting. The reserve supply is the lower position of the fuel tank and should be used for the circuit etc., at the end of a flight. A hand fuel pump is fitted on one machine and should be used to re-establish flow from the reserve supply, if the engine has already quit in flight in event of a fuel pump failure. If necessary the engine can be kept running on the primer until the main fuel pump is working. Approach and Landing Do not make prolonged glides as the engine cools rapidly and is very susceptible to [quitting?]. A high approach speed gives better control and a view ahead. The aircraft can be wheeled or 3 pointed but should not be landed tail low or it may bounce violently. A wheel landing is safer and recommended unless the ground is very smooth. Keep the tail high for as long as possible as this prevents tipping into a wing skid if one wheel runs over a lump. The rudder is blanketed with the tail down and if a swing occurs it may be uncontrollable. Do not land on concrete as this aircraft will ground loop. Normal powered approach speed 120 km/hr (This is only 65 knots). Stopping The engine is stopped by switching off and opening the throttle. Both fuel and oil cocks should be turned off.
