Hello!

Is it possible to use G-force as landing rate instead today used  fpm? more used in IRL.

Hi,

I have been a member for almost 16 years and we have always used FPM,so i cannot see a change forthcoming in my opinion.

AFAIK G-force is only used in military high speed jets, but i stand to be corrected on anything I have stated.

Mark will of course confirm this or not as the case maybe.

Hello,

Many thanks for Your replay and I understand Your opinium!

Hi,
Landing G-Force Display Added

Following a request from members, we have now added an estimated landing G-Force value to the flight report summary.

The simulator log only records touchdown vertical speed (landing rate in feet per minute) and does not provide actual vertical acceleration data. Because of this, the G-Force shown in the report is calculated from the landing rate using a standardised physics approximation, rather than being directly measured by the simulator.

The calculation works as follows:

1. The landing rate (ft/min) is converted to metres per second.

2. We assume a typical airliner landing gear compression time of 0.30 seconds as the aircraft settles onto the runway.

3. From this we estimate the vertical deceleration and convert it to G-load.

The formula used is:

sink rate (m/s) = |landing rate| × 0.00508
g ≈ 1 + ((sink rate / 0.30) / 9.80665)

This produces a realistic estimate of the load experienced during touchdown.

Typical results look roughly like this:

• 100 fpm ≈ ~1.15 g

• 200 fpm ≈ ~1.30 g

• 300 fpm ≈ ~1.50 g

• 400 fpm ≈ ~1.70 g

• 500 fpm ≈ ~1.90 g

For reference, most real airline landings typically fall between 1.2 g and 1.6 g, with anything above ~2 g considered a firm arrival.

The new G-Force block now appears next to the landing rate in the flight report summary.

Hello!

Im very glad to see this update. Your matematical formula is very well calculated and mirror the real compression of the airliner landing gear. 

Many thanks!

Mark great job, I think everyone has been waiting for this for a long time, That's why I think our virtual airline is the best because it's constantly developing. Words of respect for you Mark and Sven-Erik  

Is it possible to adjust/remove the penalty for landing 'too softly' if you do it within the touchdown zone on a dry runway with favourable winds? - I've just been (unfairly) penalised for safely buttering it into Bristol

Penalty removed, scoring profiles updated. This is some old legacy code based on an opinion over 10 years ago; it's unfair and disproportionate, especially as we have a new mechanism to process the complete picture.
