4.7 Cruise
Note: Typical economic cruise speeds lie in the range 80 to 105 mph (70 to 90 kt); 109 mph (95 kt) with
the 100 hp engine.
Maximum continuous engine speed is 5500 rpm for the 100 hp 912ULS.
Variations in rpm and cruise performance occur with different loads.
Typical cruising flight (100 hp)
Engine speed: 4800 rpm.
Airspeed: 100 mph (85 kt)
Fuel flow: 3.6 US gallons per hour, (14l/h)
The maximum speed in cruising flight is 118 mph (103 kt).
Note: This maximum speed applies only in smooth conditions with no turbulence. In turbulent
air, speed must be kept below V = 110 mph (96 kt).
4.8 Approach
Entering a conventional circuit in the cruise 92 mph (80 kts) when on the base leg reduce power,
maintaining attitude allowing a reduction in airspeed to 78 mph (68 kts ≙ 125 km) (white arc) select flap
at position 2 (11°, half flap )15 degrees flap (1 stage) simultaneously lowering the nose to maintain 67
mph (58 kts) and trim.
On final approach if the crosswind component is less than 12 mph (10 kts) you can select full flap
simultaneously lowering the nose to maintain 55 kts. Continue your approach at 63 mph (55 kts) and trim
if required. Minimum approach speed in this configuration is 62 mph (54 kts).
In calm conditions it is acceptable to use side slip technique to increase your rate and angle of descent,
but it is recommended the aircraft is returned to a standard approach configuration before reaching 100
ft above the runway.
4.9 Normal landing
In the landing phase during the hold off when the main wheels touch ensure that the nose wheel is
maintained clear of the runway during the landing roll bringing the stick steadily rearward until it reaches
the backstop and allow the nose wheel will settle onto the runway as the speed decays.
Caution should be exercised when applying brakes as it is possible to lock the main wheels under certain
conditions. It is preferable to allow the aircraft to de-accelerate to a walking pace before applying any
braking action.
Cross wind landing technique:
Establish the aircraft on a powered approach, tracking the centreline and allowing for drift. For crosswind
components of 12 mph (10 knots) or above only flap position 2 (half flap) is recommended. Approach
speed should be 66 mph (58 kts).
