5. Performance
5.1 Introduction
When using the data for planning purposes, apply sensible safety
factors, such as are contained in CAA GA Safety advice (see section 5.5
below)
5.2 Climb
Speed for best rate of climb (V
Y
) is 65 kn / 75 mph. Best angle of climb
speed (V
x
) is 57 kn / 65 mph. When selecting a climb speed, always
remember that should anything go wrong, more speed gives you more
time to sort your problems out. Although climb performance may
change between aircraft, the best climb speeds should not vary
significantly.
5.3 Glide
Speed for best glide angle is 58 kn / 67 mph, at which a glide ratio of
around 8.5 to 1 may be expected. Flying a little slower at 48 kn / 55
mph will give the minimum descent rate (min sink) of around 580FPM.
5.4 Cruise
The Nynja 600 can cruise at a large range of airspeeds. The best
theoretical still air range will be at a low airspeed of around 60 kn /
70mph, at which fuel consumption will be 10LPh or less. At 80kn /
92mph fuel consumption will be around 13LPH, and at 100kn /
115mph fuel consumption will rise to over 20lph. At maximum
continuous RPM the fuel burn will be more than 25lph – i.e. a lot more
fuel consumption for a diminishing airspeed increase.
Exact fuel burn will vary with take-off weight and density altitude. The
pilot is encouraged to plan very conservatively until sufficient
experience is gained of the fuel consumption and cruising speeds at
the conditions in which the aircraft is normally flown.
