Brake Operating Limitations
If the brake is needed during landing, exercise great care and remember the following procedures:
1. Apply the brake gently once the aircraft is stabilised after landing.
2. If the rear wheels lock and the aircraft starts to slide, release the pedal immediately and re-apply
more gently once the aircraft is stable once more.
Engine Run-Up
Operators should note that with the engine running above idle the aircraft may tend to creep forward with the rear
wheels locked on some surfaces. See warning Section 7.4.
Inspection
The amount of wear that takes place on the tyres and brakes will vary from one aircraft to another, depending on
the type of surface the aircraft normally takes off and lands on. Close inspection of the brake pads should be
made at intervals of no more than 100 hours.
8.4. TAKE-OFF
Performance
The takeoff performance given in section 3.8 is on short mown grass. Takeoff could be shorter from tarmac, but
longer if from wet ground, if the ground slopes upwards, or if there is any tailwind. A significant headwind would
reduce the length of the take-off run considerably; conversely, long grass or soft ground will considerably
increase the take off run. See CAA safety sense leaflet 7A, performance.
Density altitude will affect take-off performance: for example at 4000 ft altitude the takeoff run will be 1.9 times as
long, and if the temperature is 32
C at 4000 ft, the run will further increase to 2.1 times as long.
Before Take off Checklist
Performance Calculations
:
(see above)
Wing visual check
: nose, front rigging, side rigging, tip rods, ribs, rear rigging, hang-point bolt, control frame
and bolts, basebar bolts.
Trike
: front strut pins/rings, brake operation, steering free, baggage box lids secure, harnesses, side skirts
secure, ignition switch check operation and magneto drop, intake and exhaust system secure, hand and foot
throttle operation, mixture rich.
Magneto drop
: check brakes on, at engine idle turn OFF both magneto switches, check for dead cut, and turn
on again. Idle speed should be set at around 1400 RPM for the Rotax 912S/912 engine. Run engine to 3850
RPM, then turn OFF front magneto. Listen for any misfire and observe mag drop (see also Engine Operators
If the brake is used as an emergency landing brake in wet and icy
conditions, extreme care must be exercised. If the aircraft veers,
or the wheels lock, release the brake pedal immediately and steer
towards the direction of the veer.
Exercise great care in strong crosswinds and
turbulent conditions.
Before take-off or landing at altitude, in hot
conditions, on a short strip and particularly in
the case of a combinaton of all three, do your
density altitude calculations.
If the wing is wet, take off distance can be up to
30% longer.
