The perfect approach

Hi Doug,

"Friedrich Ostertag" wrote in message I always
thought jets were supposed to land with about 70-80% power on, to be
prepared for a potential go-around? (Because spool-up time from idle
would be prohibitive in that case?)

Perhaps you are confusing RPM with thrust?

seems to be the case, as far as the figures are concerned.

The correlation is not
linear. Normally the RPM is between 70% to 80% on approach, but the
thrust around 20% to 25%. You are correct that normally the engines
are somewhat spooled up to provide adequate acceleration if needed.
Hence the reason I carried an extra 20 knots of airspeed into the
flare when using idle thrust.

thanks for the explanation!

regards,
Friedrich
