A Day in the Life of a Performance Engineer

Andreas Saf-PernseliusAndreas Säf-Pernselius is an Aircraft Performance Engineer at our Sweden office. He is trained as a Mechanical Engineer and holds a commercial pilot’s license. He has five years of aviation experience including experinces from the Swedish Air Force. He joined Navtech in 2009.

“I really enjoy my work at Navtech because I feel we are making a significant contribution to the airlines’ safety and efficiency”, says Andreas. “It is a great experience to work with airlines and airports from all over the world.”

Typically, a day starts with checking the performance@navtech.aero mailbox for the daily support issues, orders or critical items that require immediate attention. The mailbox is our main source for the work and continues to be checked throughout the day. Incoming emails are evaluated and, either dealt with immediately or assigned to a colleague for further investigation. All emails are added to the our internal request tracking system (MKS).

The  next activity would be to start going through and analyzing the incoming NOTAMs that have been published since the previous day. This work involves checking to see if the published NOTAMS are related to any of the airports that we maintain and keep under surveillance in our master database  manager,  APEx (Aircraft Performance Explorer). NOTAMs affecting performance calculations will be amended to APEx and before release in the system, all changes are double checked and released by a second team member to avoid misinterpretations and mitigate human error factors. At the end of the day, after all the NOTAM changes have been released, the operators with affected runways in their subscription will receive a new airport obstacle database. This is an automatic process that is initiated at the end of the work day. The rest of the day is allocated to a range of other tasks which could include:

  • Adding new airports to APEx, which involves looking at the AIP information and analyzing the surrounding terrain to find the best data source and the most optimized engine failure procedure based on TKOF weights.
  • Answering customer questions regarding the data and the procedures that have been created.
  • Reading the “AIS Daily Bulletin” received from the Navtech office in the UK where all new, received documents are published on a daily basis. These documents are printed, analyzed and evaluated for changes in amendments, supplements and forthcoming AIRAC changes. These changes are amended in APEx, and double checked by a second team member before being released in the system.
  • Discussing with colleagues how certain data should be interpreted and added in APEx.
  • Updating the Engine Failure Procedures to our new standard. This project is a huge effort and we are almost “half way there” to have all our procedures in the new standard.
  • Implementing new customers, including aligning deadlines with the Performance Software department to enable a joint delivery of the Airport Obstacle Database together with ToDc.
  • Keeping our product updated and valid according the latest regulations. And, also trying to meet our customers’ requests which are often of a large variety of complexity.
  • Collaborating with Navtech’s other departments because our procedures are used in the Navtech Charts products.
