Flight Manual: Saab 35 Draken 5.0Updated: 2019-11-02


MISSING GRAPHIC: ../graphics/41_cover_cropped.jpg

Thank you for purchasing our simulation of Saab 35 Draken, the legendary Swedish jet fighter/interceptor that served in four national air forces during five decades.

This document explains how to install and use Draken version 5.0 for Lockheed Martin Prepar3D. The Microsoft Flight Simulator versions are not covered in this manual, they have their own documentation.

For technical support and feedback please refer to the Bookmark Simulations website.

Please Read The Fine Manual

This is a complex simulation of an old non-NATO military jet. Most of the instruments and switches in the cockpit are labeled in Swedish, and they are sometimes not intuitive regarding their function. You are therefore strongly recommended to read through this Flight Manual before your first flight.

The Flight Manual describes all the simulated systems, gauges and controls in the aircraft and how to use them. At the end of the document is an appendix with technical data, radio frequency tables, procedure check lists and a short glossary translating the Swedish instrument panel labels into English.

All the simulated components of the current version are described in the Flight Manual. Some systems and functions that are not simulated are described anyway because they are visible in the cockpit or referenced in some way.

Please bear in mind that this is in no way intended to be a full or accurate description of the real aircraft.
