Results of MLS procedural interception flight trials performed at Manchester Airport

In July, 1988, flight trials have been performed on the newly installed MLS equipment at Manchester Airport (UK), using one of the laboratory aircraft of NLR, a Fairchild Metro II with programmable avionics systems including a basic MLS receiver as an "Avionics Research Testbed". The aim of the tests was to prove that aircraft with basic IFR...

The need of stick force stability for attitude-stabilized aircraft. Part II

A description is given of flight tests related to the effect of various levels of (artificial) positive stick force stability on the longitudinal controllability in the landing approach of an attitudestabilized aircraft. Approach performance and pilot commentary of 60 ILS/VASIS approaches flown with a twin-engined jet transport have been...

The need of stick force stability for attitude-stabilized aircraft. Part 1

After introductory background information on the landing approach piloting task and some arguments for expanding the knowledge on handling quality criteria for certain advanced transport designs, results are given of flight tests related to the effect of positive stick force stability on the longitudinal controllability in the landing approach...
