climb gradient
hi,
reading through different literature regarding min climb gradient at various stages on take-off and landing.
but different books mention different values for same stages and for same #of engines.
eg.
1st seg= positive gradient or .3%
2nd seg= 2eng 2.4%
3eng 2.7%
4eng 3.0%
other books just 2.4% for all
another book 2.0%
3rd seg= 2eng 1.2%
3eng 1.5%
4eng 1.7%
other books 1.5% for 3rd seg no matter #of engines
4th seg= 1.5% for all
another book 1.2%
missed approach= 2.5% for all #of eng.
landing climb gradient(all eng working)= 3.2%
approach climb gradient (OEI)= 2eng 2.1%
3eng 2.4%
4eng 2.7%
do i get confused between gross and net and different authorities require different values?
thanks trot
