Procedures for Aircraft Operators

Why aircraft operator’s requirements need to be addressed individually?

Safety shall always be the highest priority when designing a flight procedure. The specific characteristics of a flight procedure consider obstacle environment, navigational aspects and local conditions. However, design criteria have been formulated with a view to achieve a reasonable degree of standardisation neglecting a wide variation of aircraft types at heterogeneous aerodrome and airspace environments. Consequently, the specific needs of aircraft operators with regard to operating fleet and aircraft performance are not addressed. NavDelta is able to perform optimisation processes of flight and operating procedures providing tailored solutions for each individual case.

How does NavDelta provide efficient procedures for aircraft operators?
NavDelta can determine a potential to reach operational and economical gain by adjusting procedures to specific operator requirements without reducing level of safety. We develop tailored procedures by means of in-depth analyses of aircraft performance, flap schedules, fuel consumption and more operational aspects. The field of such applications range from frequently flown locations with procedures published in the State Aeronautical Information Publication (AIP) to aerodromes where instrument flight procedures are not implemented yet. 
 
 
 

 

What are our activities?
  • Determination of tailored IFR procedures (“company procedures”).
  • Design of RNAV overlay procedures (IFR and RNAV visual).
  • Aircraft performance calculations and evaluation.
  • Analysis and optimisation of flight operational procedures regarding fuel and emission efficiency.
  • Analysis and optimisation of aircraft configuration including flap schedules and flap settings.
  • Implementation of continuous descent and climb operations (CDO and CCO).
  • Determination and evaluation of flight tracks for one engine inoperative conditions.
  • Design of noise abatement departure procedures (NADP) for aerodromes.
How can you benefit from RNAV Visual approaches?

Some locations are not equipped with navigational aid infrastructure or have no instrument flight procedures published for various reasons. Is such cases visual approaches may be conducted which are highly dependent on weather and visibility as well as contribute to a higher number of unstable approaches. Due to a wide availability of satellite navigation it is possible to enhance visual approaches and departures by providing optimised prescribed tracks coded into FMS. Even though “RNAV Visual approaches” are not instrument flight procedures as defined by ICAO PANS-OPS, they result in significant operational benefits, improve terrain situation awareness and can assist navigation of an aircraft.
