The radial red line near the bottom of green arc indicates V mc, the minimum indicated airspeed at which the aircraft can be controlled with the critical engine inoperative. The radial blue line indicates V YSE , the speed for best rate of climb with the critical engine inoperative.
The flight test phase can range from the test of a single new system for an existing vehicle to the complete development and certification of a new aircraft, launch vehicle, or reusable spacecraft. Therefore, the duration of a particular flight test program can vary from a few weeks to years.
Flight test instrumentation (FTI) is monitoring and recording equipment fitted to aircraft for specific flight tests. The development program for a new aircraft design has a number of aircraft each of which has tasks to perform for development and certification tests. They are each fitted with FTI specific to their allotted tasks.
With the TS-4530A certification in place, the Company has now secured AIMS approval on three Mode 5 flight-line test sets, including the CRAFT AN/USM-708, the CRAFT AN/USM-719, and the TS-4530A ...
An air data boom provides air pressure, temperature, and airflow direction data to data acquisition systems for the computation of air, ground, and water vehicle orientation, speed, altitude/depth, and related information. Air data booms can be used as primary sensors or as a "measurement standard" of which primary sensors and instruments are ...
Birgenair Flight 301 had a fatal pitot tube failure which investigators suspected was due to insects creating a nest inside the pitot tube; the prime suspect is the black and yellow mud dauber wasp. Aeroperú Flight 603 had a fatal pitot-static system failure due to the cleaning crew leaving the static port blocked with tape.
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
Here the speed is displayed both in knots (kn) and miles per hour (mph). The true airspeed (TAS; also KTAS, for knots true airspeed) of an aircraft is the speed of the aircraft relative to the air mass through which it is flying. The true airspeed is important information for accurate navigation of an aircraft.
