Does the MD-11 autopilot stay on or kick off during an autoland G/A?

0

Here are the conditions during an autoland approach (tested in the simulator): MD-11 450,000# Flaps 50 No difference whether in Single Land or Dual Land. G/A button pushed WITHOUT moving throttles: 1) Pressing G/A button as low as 10′ (throttles in “Retard”), IF the airplane DOES NOT touch the runway: – All three throttles come up, – Autopilot stays on- – a “Normal” autoflight G/A as we’d expect. 2) Pressing the G/A button just BEFORE touchdown, If the airplane DOES touch the runway: – Spoilers deploy – Only throttles 1 + 3 come up – #2 throttle only partially comes forward – (Spoilers stay deployed) – Autopilot STAYS ON. – Airplane goes into an automated G/A with spoilers deployed and partial #2 throttle. [“Ugly”] – NO Tailstrike occurred (tried several times) 3) Pressing the G/A button just AFTER touchdown (or anytime after touchdown or during “Rollout”), – Spoilers deploy – Only throttles 1 + 3 come up – #2 throttle only partially comes forward – (Spoilers stay deployed) – Autopilot
