1. Flight Test Analysis
This is an introduction to MATLAB designed to accompany the Advanced Data Management telemetry demo.
This demo highlights some of the key aspects in the Technical Computing Workflow.
Maneuver Overview
A common maneuver in flight testing is the wind-up turn. The wind-up turn is a test maneuver that enables
calculation of "stick force per g", a measure of longitudinal stability.
Aircraft are designed to have some degree of longitudinal stability. Longitudinal stability is a measure of when
an aircraft is disturbed from a trimmed position, how likely it will return toward that same flight condition.
An aircraft with a high degree of longitudinal stability will be more difficult to move from the trim condition
than one with low stability. More pilot effort will be required to move the aircraft away from trim. Thus it will be
more difficult for the pilot to maneuver.
This example loads a data set from a wind-up turn and generates the time plots to explore the data. We
calculate "stick force per g" for the stable section of flight.
This is provided for example purposes only.
Load the Data
Read the flight test data into a table. We could read in with Import Tool, or for simple files just
call readtable.
d = readtable('FlightTestData.xlsx')
d = 800×7 table

store dates in a container called a datetime which provides a number of useful features for working with
time data such as easy ways to handle time zone changes, leap years, and calculating durations.

Verify Airspeed Stability
For this data to be useful, the airspeed must remain relatively constant throughout the maneuver. Visually
inspect the data to ensure we are within 5 knots during the smooth section, or within 10 knots during the stall
buffet.
Compare airspeed with load factor over the same flight regime. We again use interactive tools to customize
the display of the plots and generate MATLAB code to reproduce the exact appearance.

10. Subset Data
Take only the data after we have settled into the turn, and before the stall buffet begins. This is between
12:45:05 and 12:45:30. This uses a powerful subsetting syntax in MATLAB called logical indexing - the
second line of code keeps all of the rows of our table where sec is between 5 and 30 seconds.
sec = second(d.Time);
windup = d(sec > 05 & sec < 30, :)
windup = 499×7 table

14. Compute Stability Margin
Plot Load Factor (g) verse Stick Force (lbs.) for the stable section of the flight, and compute the best fit line
for the region. The slope of the line is the stability margin.
clf
fit = polyfit(windup.LoadFactor, windup.StickForce, 1);
plotStability(windup.LoadFactor, windup.StickForce,fit)

Demonstration Summary
This demo introduced the following MATLAB features:
• Import Tool (R2011a): Interactively import data from text and spreadsheet files
• Live Editor (R2016a): Combine code, output, and rich formatting to create sharable programs
• Interactive Plot Editing (R2016b, R2017a): Explore and annotate your plots. Automate with
automatically-generated MATLAB code
• yyaxis (R2016a): Overlay plots with a shared X axis but different Y axis.
