Nardi FN-333 Riviera Handbook:

Startup Procedure:

To Startup the engine, first check if:

Mixture : 100%
Fuel Pump: ON
Fuel Valve: OPEN
Fuel Selector: BOTH
Magnetos: BOTH
Throttle: 0%

Then turn the starter key and wait for the engine to start. Idling RPM is around 1000.

Taxiing- GROUND:

Taxiing on ground is accomplished by just adding a little of power and steering with Rudder Pedals. You may use reverse thrust to go backwards, but don't let the aircraft gain too much speed while backing up. The riviera can spalsh from the ground to the water if the shore is adequate (on Flight Simulator this can always be done). From groud to water you need to lower your floats before entering water, and it is better to leave water rudder UP during the transition to avoid it hitting the ground. Once you are floating, retract the landing gear (it is prepared for such operation).

Taxiing- WATER:

Taxiing on water requires more power than on ground to start moving. Steering with Rudder Pedals can be done when there's enough speed, otherwise the water rudder should be used. You may use reverse thrust to go backwards, but in water the system needs to be "forced" to run at a higher power or it will not be enough to start moving. To do this, quickly move your throttle to any desired setting between 35% and 70%, quickly cut off to 0% and pull the reverse lever (or press F2). Again don't let the aircraft gain too much speed while backing up. The riviera can get out from the water to the ground if the shore is adequate (on Flight Simulator this can always be done). From water to ground you need to extend your landing gear uderwater (it is prepared for such operation). It is better to set water rudder UP during the transition to avoid it hitting the ground. Once you are on ground, retract the floats.

Taking Off - GROUND:

To Take off, set elevator trim at 0% or accrdignly on your CG position - aircraft load status. Set one notch of flaps (11°). Make sure that Propeller condition is at full forward. Check that water rudder is retracted and floats are UP. Advance Throttle to 100% (or derated if possible) slowly and rotate when the aircraft reaches 60 KIAS. After the aircraft lifts off, retract your landing gear, and set prop pitch to bleow 2500 RPM (yellow line) to prevent engine from overheating and oil pressure to stay on red line. Maximum power of 250 HP @2600 RPM (Full Forward) is available only for short time. When enough speed is reached (~96 KIAS) retract flaps.

Taking Off - WATER:

To Take off, set elevator trim at 0% or accrdignly on your CG position - aircraft load status. Set one notch of flaps (11°). Make sure that Propeller condition is at full forward. Set Water Rudder as desired and leave floats DOWN. check landing gear UP. Advance Throttle to 100% (or derated if possible) slowly and rotate when the aircraft reaches 60 KIAS. After the aircraft lifts off, retract the floats. Set prop pitch to bleow 2500 RPM (yellow line) to prevent engine from overheating and oil pressure to stay on red line. Maximum power of 250 HP @2600 RPM (Full Forward) is available only for short time. When enough speed is reached (~96 KIAS) retract flaps.

Manoeuvering- turns :

The Riviera need a little of rudder pressure in the direction of the turn to compensate the little slipping that otherwise occurs. The tighter the turn, the more the rudder required. After a certain bank angle is no longer possible to compensate the slip without losing rapidly altitude.

Cruise:

You Can cruise at altitudes Up to 8000 Ft or as high as you can breathe on a non-pressurized aircraft... With a throttle setting at about 75% you should travel at around 130 KIAS. Remember to set prop pitch for a maximum RPM of 2500. You can set it at lower values for noise reduction or greater fuel economy at altitude.

Landing - GROUND:

To land on ground check: Floats and Water rudder UP. To Land You may keep a speed not lower than 41 KIAS that is full flaps stall speed. Lower than 45 the plane approaches stall and becomes unstable. You can anyway try (at your own risk) to land at 40 KIAS for very short-field results. Ideal landing speed over the fence is about 60 KIAS, then you just throttle back to idle and gently pull the nose up. Landing is always done with full flaps. Propeller must be reset to full forward during the short final approach in order for the reverser to work properly. You can either stop the Riviera by braking, engaging prop reverser or simply letting it roll. Applying brakes and reverser will stop the plane very quickly.

Landing - WATER:

To land on WATER check: Floats DOWN and Water rudder AS DESIRED, Landing Gear UP. To Land You may keep a speed not lower than 41 KIAS that is full flaps stall speed. Lower than 45 the plane approaches stall and becomes unstable. You can anyway try (at your own risk) to land at 40 KIAS for very short-field results. Ideal landing speed over the fence is about 60 KIAS, then you just throttle back to idle and gently pull the nose up. Landing is always done with full flaps. Propeller must be reset to full forward during the short final approach in order for the reverser to work properly. You can stop the Riviera only by engaging prop reverser (brakes won't be of any use...).
