PROCRU simulation results compared with Metro II in-flight ILS approach data

The PROCRU (Procedure Oriented Crew) model has been developed for the analysis and modeling of flight crew procedures during an ILS approach. The model's specific capability concerns the generation of "timelines" of the necessary actions to be carried out by each crew member during the approach. Besides, also the corresponding timelines for...

Analysis of possible interference in radio altimeters induced by a position marker system called RASP

An analysis is given of possible interference induced by a position marker system, called RASP, into aircraft radio altimeters. The RASP system is used as a marker beacon in flight tests for trajectory measurements, and operates on 4.3 GHz. It is concluded that radio altimeters will not experience any harmful interference from a RASP transmitter.

A method for measuring take-off sjid landing performance of aircraft, using an inertial sensing system

The STALINS method for measuring take-off and landing trajectories is briefly described and results of flight tests made in 1978-80 are discussed. The method now meets the requirements to which it was designed, and a few improvements in the hardware and software are being finalized. The method is expected to be ready for operational use in the...

Determination of low-speed longitudinal manoeuvring criteria for transport aircraft with advanced flight control systems

The application of Active Control Technology concepts and in particular the Relaxed Static Stability principle in certain categories of future transport aircraft will lead to the introduction of primary flight control systems incorporating full-time stability augmentation. For this category of transport aircraft adequate handling quality...
