Instrument Flight Procedure Design Services

 

Fly-By NUNES have over 20 years experience in the Aeronuatical sector including designing Instrument Flight Procedures.

What is an Instrument Flight Procedure?

IFPs (Instrument Flight Procedures) simply put, are safe flight paths for aircraft; Fly-By NUNES design and publish these in the form of an A4 or A5 size chart, which indicate the flight path as a plan view and profile view, surrounding topography, and significant obstacles.

They are used by Air Traffic Control (ATC) and aircraft pilots flying in accordance with IFR (Instrument Flight Rules). IFPs are designed to achieve and maintain an acceptable level of safety to protect aircraft in flight, from permanent obstacles such wind farm developments, buildings, mobile phone masts such as 5G masts or radio masts, television masts and data communication masts, especially in bad weather when the visibility is low. 

Flight Procedure Types that we design include:

  • Approach Procedures - used for approach and landing

  • Departure Procedures - used for take-off

  • En-route procedures - used between city pairs or between countries

  • Arrival Procedures - used to connect the en-route procedures to the approach procedures. 

Please contact us if you would like more information about how we can help you with Instrument Flight Procedures.
