      TuneVNAV Descent Pro3 is a FMC like software that calculates the exact descent & approach
       speeds of a descending airplane, all the way to the runway.
       You can now easily select any Terminal Procedure for any APT in the World (AIRAC cycles).
       The computed approach speeds are the exact ACRFT's Maneuvering speeds!
       Adjust your FMC with the TuneVNAV Pro3 computed speeds on the ground, at the departure APT!
       NEW: Selecting the Emergency option, you can make these calculations for any Flaps position as 
        Landing Flaps!

1. Navigraph AIRAC cycles for any APTís TP.
2.Updatable Airplanes DataBase
3. Contains Airbus & Boeing Airplanes Database 4. Instant calculation of all the descent and approach speeds!
5. The approach speeds are exactly the Maneuvering speeds!
Make all the calculations on the ground, at the departure APT!
6. Accurate computed Mach Speed.
7. Print a hard copy of any computed flights.
8. ACRFT Weight in lbs or Kg.

TuneVNAV Descent Pro3 uses ONLY TuneVNAV Pro3 AIRAC cycle files created by Navigraph.

July 08 (0807) AIRAC cycle is embedded into  TuneVNAV Pro3 setup file, so once installed,  you can start  using  TuneVNAV Pro3 right away!

month AIRAC cycle (setup file) is already available at

For best performances, make sure that you are using the same AIRAC cycle on both Add-ons (ACRFT & TuneVNAV Pro3)

1. Select the ACRFT from the ACRFT Database.
2. Enter the Destination APT's ICAO code.
3. Hit the Get APT button to load the APT's TP.
4. Select the STAR  &  STAR TRANS and RWY# & RWY TRANS (as in the FMC)
5. Hit the SET APT CONFIG button.
6. Enter the Cruise Altitude for the flight.
7. Enter the ACRFT's ZFW (Zero Fuel Weight), AFW (Arrival Fuel Weight), Cruise Speed and Econ Descent speed (ALL of these from the FMC)
8. Hit the AutoTuneVNAV button.
9. You get the results instantly on the TuneVNAV Results page.
10. Adjust your FMC Waypoint's speeds with the ones computed by TuneVNAV Pro for safe and worry less landings.

New in TuneVNAV Pro3 v.3.1
Emergency landing option added:
If you can't get out the proper landing flaps, TuneVNAV Pro3 v.3.1 is now able to calculate for you the proper descent & approach speed all the way to the runway considering the available flaps position as the landing flaps.

New in TuneVNAV Pro3 v.3.2
New planes added:
MD 11, CRJ 200,  CRJ 700, CRJ 900
