  • Page 12 3. Any increase in maximum weight will result in an increase in take-off and landing roll, and will also decrease the rate of climb. For safe operations, the maximum weight should allow the aircraft to climb at a minimum of 600 ft/min in sea-level standard conditions. F.8L Falco Flight Manual 2–3...

    As the ground is approached, the aircraft may be flared out by carefully employing the elevator trim control. The throttle is closed immediately prior to contacting the ground. F.8L Falco Flight Manual 3–4...
  • Page 21 If the aircraft is in a flat spin and standard recovery techniques have failed, experience with other aircraft has shown that opening the canopy can sometimes assist in the recovery since the airflow over the canopy can cause the aircraft to pitch nose-down. F.8L Falco Flight Manual 3–5...
  • Page 22 Such preparations, however, should not be used if they will prevent the control of the aircraft. All such impacts should be made in a normal landing attitude (wings level, nose high) and as slow as possible (flaps fully down). F.8L Falco Flight Manual 3–6...
