Avianis FT

The new Avianis Flight Time ("FT") calculation method is a point-to-point/great circle mapper with improved performance models and the latest/updated historical wind data from NOAA. Avianis FT takes 6 inputs - that may all be customized by the user by tail - to calculate the estimated flight time. Winds aloft impacts are applied only for the cruise portion of the flight, averaged over the past 5 years for the month of departure at the cruise altitude for the applied performance profile line. 

Avianis FT Settings

When Avianis FT is selected for any of the four Flight Time Calculation options, the blue Settings button next to it will open the modal to edit.

Changing the settings will change for all options where Avianis FT is applied. For example, editing Settings launched from Trip Domestic Flights will make the same changes to Quote Domestic Flights if Avianis FT is also applied.

Performance profiles (rows) may be added or removed, but at minimum there must always be one profile. All profiles must have all 6 fields and NM range provided.

Avianis FT Setting Fields

There are default values applied to all aircraft for Avianis FT, but all may be edited/customized. The following fields are provided on an Avianis FT Performance Profile:

1. Distance (NM) - Determines which profile is applied to a flight. E.g. if a flight is 62 NM, then it will use the profile for 50-150 NM. When the distance is entered, the rows will automatically rearrange themselves to be in a logical order. 
   
2. Cruise Alt (ft) - Expected cruise altitude for the flight, indicated in imperial feet. Flight will calculate climb up to and descent from this altitude. This is also the altitude of the winds aloft that will be applied to the cruise.
   
3. Cruise Speed (KTAS) - Expected cruise speed for the flight, indicated in true knots. 
4. Climb Rate (fpm) - Expected climb rate for the flight, indicated in imperial feet per minute. 
   
5. Climb Speed (KTAS) - Expected climb speed for the flight, indicated in true knots. Wind impacts will not be applied.
6. Descent Rate (fpm) - Expected descent rate for the flight, indicated in imperial feet per minute. 
7. Descent Speed (KTAS) - Expected descent speed for the flight, indicated in true knots. Wind impacts will not be applied.
   

Avianis FT Auto-Config

The automatic configuration ("Auto-Config") feature is meant to quickly build or adjust the Avianis FT performance profiles based on existing flight data for an aircraft. Auto-Config considers up to 50 of the most recently logged flights for that aircraft for each performance profile (NM) and does the reverse math to provide the average cruise, climb, and descent speeds. 

Requirements to run auto-config for an aircraft:

1. Must have at least one performance profile (row) added
   
2. Must have the following fields provided for each performance profile: NM, Cruise Alt, Climb Rate, and Descent Rate.
   
3. Must have a minimum of 5 flights logged for each performance profile
   

Given all 3 of the requirements above are met, auto-config will run when the button is pressed. Auto-config may take up to several minutes, during which time a logo spinner will be shown (see image below). Do not close or cancel the modal while auto-config is running or it will not complete. 

When auto-config completes, the Cruise Speed, Climb Speed, and Descent Speed will automatically update with the values that will produce results most similar to the flights already logged by that aircraft.

Avianis FT Copy From

The 'Copy From' setting provides a quick way to reuse Avianis FT performance profiles that have already been applied to another aircraft. Clicking the Copy From button will reveal an additional field where another aircraft may be selected. After pressing the green check mark button the performance profiles from the selected aircraft will populate. The fields may be further edited, if desired. The performance profiles are still managed separately; in other words, editing one aircraft will not edit the other moving forward. To keep them aligned the updated profile must be copied again to the other aircraft.

Avianis FT Default Performance Profiles

To jump start the adoption of Avianis FT, default performance profiles have been applied to all aircraft. Default performance profiles are meant to be approximate and provide a starting point to build out and customize. The fastest way to do this with aircraft that have been in the application for some time is to use the auto-config option. 

There is no connection or transference from Great Circle (Legacy) performance profiles to the Avianis FT because it is a completely updated model that would not produce the same calculations. 

Default performance profiles are applied to aircraft based on their category/size. The default profiles are:

Avianis FT Calculation Transparency

When the Avianis FT is applied on either a Trip or a Quote, the flight time calculation method pop-over may be opened to see details on how the flight time was generated. Use the information to verify the performance profile applied, estimations for each segment of flight, the wind adjustments, and the rounding method (if applied).

Avianis Predictor

As of December 2024, the Avianis Predictor is still in BETA version and only available to enterprise customers by request. If you would like to participate in user testing, contact your account manager.  

1. Operated by the same aircraft FAA type
   
2. Within a +/- 30 day range of scheduled departure date for this year and any previous year
   (This is to align with any seasonal weather or congestion patterns.)
3. Where the departure and arrival airport are within a 50km radius of the operated airports
   
1. If non-exact match airports are considered, a +10% time adjustment is added

Avianis Predictor Aircraft Options

1. Consider Global Data, with 3 options:
   
1. "Always Use Global Data" - The Predictor will always use all available data. [Highly recommended / best option] 
   
2. "Only use when My Company data is insufficient" - The Predictor will prioritize only considering flights logged by your own company. Only in the event where there are less than 10 flights that meet the criteria, where the Predictor would otherwise fail, will it use global data from other sources. 
   
3. "Never use Global Data" - Regardless of the number of flights, the Predictor only ever consider flights logged by your company in Avianis. [Greater potential for failure due to insufficient data] 
2. Insufficient Data Fallback - The selected FT calculation method will be used in the event there is insufficient data to use the Avianis Predictor or there is an error. (Avianis FT is the default method selected.)

Great Circle (Legacy) calculation method will be discontinued in 2025, as it is replaced with the new Avianis FT. Several user-wide communications will be sent in advance of its shut down.
