04/03/2014 : Tecnam P Twenty-Ten #2 first flight report
 Under the control of Tecnam’s Test Pilot, Marco Locatelli, Tecnam’s second P Twenty-Ten achieved a faultless first flight at 11.00 UTC on 17 February 2014.
 
The P Twenty-Ten lifted off in less than 400mt and aimed to 5000ft at more than 900ft/min.
 
The second P Twenty-Ten has a new, definitive cockpit layout. It is equipped with a Garmin G1000 suite and G700 autopilot, electric pitch trim and provision for night VFR and IFR flight profiles. The scope of this second aircraft is to enable completion of certification trials in the VFR N and IFR environment.
 
Highlights from Marco Locatelli’s report include:
 
Aircraft mass was 905 kg, CG 23.5%.
 
The Lycoming IO-360-M1A, start up was flawless, engine controls precise and instrument readout is clear, both also without selecting full avionics on, which enhances a/c battery endurance and avoids any DC current peak absorption by the full Garmin suite.
 
The new electrical stepped flap control allows flap selection in three position: UP, 15° for T/O, and 41° for Landing.
 
The new free casting nose wheel system is smoother and allows “in-place” turns, pivoting on a braked main wheel. Turn radius and ground “agility” is now very impressive.
 
Aircraft acceleration to 50 KIAS took just 13 seconds and about 380 mt. 
 
Climb is performed straight ahead, into 5000ft altitude, at max engine power. Initial rate of climb is in the order of 800 ft/min, TO flap, Vy 74 KIAS. Passing 1500 ft AGL flap
are retracted, airplane accelerates to Vy clean 82 KIAS increasing it pitch attitude to about 14° above horizon and climbing at more than 1000 ft/min.
 
Trimming (longitudinal axis) is precise and quick.
 
Rudder effectiveness is excellent, control forces very low. 
 
Level off at 5000ft AGL is done after 5 minutes from brake release, overhead Capua field.
 
Slow down runs at 1 kt per second are executed in clean, T/O and LD flap condition, at 5000 ft AGL, idle power.
 
Apart stall warning aural indicator, a first natural pre-stall (flap UP) indication is achieved when, at almost full back stick (trim set for 1,3 Vs1 calc), external aerodynamic noise abruptly washes out at 67-70 KIAS and cockpit environment gets unnaturally quieter.
 
The 1 G level stall flap UP happens at about 53 KIAS, pitch break absolutely symmetrical, full back stick after more than 3 seconds. As usual rudder and ailerons remain effective in post stall, visible sink rate stabilizes to 400 ft/min. Vmin (IAS) recorded around 52 KTS.
 
Outside cockpit visibility is improved thanks to sun shading and new dashboard finishing anti-glare painting, at all flap setting.
Positive glide path stability is shown at selected app speed: T/O flap down to 65 KIAS, 1800 RPM set, for 3° slope.
 
LAND flap approach and go around from 60 KIAS shows correct control behavior, easily held with a single hand.
 
Final “spot” landing is done on rwy 26 in LIAU, wind calm, LD flap, approach speed 60 KIAS with touch down is obtained on the planned runway zone at about 50 KIAS.
 
Marco comments that the P Twenty-Ten’s behavior appears safe and predictable at all investigated speed.
 
Flight controls displacement and effort curves are in the correct sense, pitch trim is effective and precise with a significantly steep effort/speed curve, which will result in a very appreciated “low workload” quality for IFR flight and for school initial trainer role.
 
The “P Twenty Ten” brings together an advanced technology all carbon fibre fuselage with a metal wing and stabilator based on the best of TECNAM’s recent P2006T Twin and P2008 offerings, this single engine, 4 seat aeroplane is eagerly anticipated by the General Aviation community.
