First Flight FTT — ABCs of FTTs #14

This column features a brief description, photo or video, and/or reference that talks about a Flight Test Technique that students at USAF Test Pilot School are currently learning. It’s an alphabetical list of FTTs together with a chronological account of what future test pilots and flight test engineers are doing right now. It will complement the previous Friday’s FTT tweets as well.

The goal of the first flight is to takeoff and then land the aircraft safely. #FTT #flighttest

Flying qualities in landing configuration are evaluated. #FTT #flighttest

Propulsion and basic air data FTTs are performed to validate basic performance of the test aircraft. #FTT #flighttest

Stall and High AOA FTT — ABCs of FTTs #13

This column features a brief description, photo or video, and/or reference that talks about a Flight Test Technique that students at USAF Test Pilot School are currently learning. It’s an alphabetical list of FTTs together with a chronological account of what future test pilots and flight test engineers are doing right now. It will complement the previous Friday’s FTT tweets as well.

Definition: stall is “uncommanded roll or yaw motion or pitch break (nose falls)”. #FTT #flighttest Other “strange” characteristics too!

Typical stall technique is wings level decel at 1 knot per second until stall. #FTT #flighttest

Why do they do stall testing?
1. Evaluate stall susceptibility
2. Evaluate stall warning characteristics
3. Determine method for stall recovery

High AOA testing may involve tufts, trailing cones, smoke, or oil to visualize airflow.

Some aircraft have a pitch or AOA limiter, as this F-16 video animation shows.

#Video: small, piston aircraft stall characteristics known as bucking. #FTT #flighttest

More Systems Flight Test Techniques — ABCs of FTTs #12

This new column will feature a brief description, photo or video, and/or reference that talks about a Flight Test Technique that students at USAF Test Pilot School are currently learning. It’s an alphabetical list of FTTs together with a chronological account of what future test pilots and flight test engineers are doing right now.

taws_2What is an FTT? It is the fundamental maneuver building block used by flight test engineers and experimental test pilots.

If you are wondering “what is a systems FTT?” then start here.

Examples of systems flight test on civil aircraft include TAWS–terrain avoidance and warning system.

Terrain awareness and avoidance are one of the hottest areas of system flight test, research and development.

TAWS (terrain avoidance warning system)–a terrain database integrated with an aircraft navigation system and multi-function displays.

@NASADryden and @LockheedMartin have been been flight testing Automatic Collision Avoidance Technology integrated with the aircraft flight control system/autopilot on an F-16 flying test bed at Edwards AFB. Click here for the NASA website, photos, and videos about the project.

2. F-16 low level from Lake Owens to Sierra Nevada Mountains

3. Synthetic Vision Systems (SVS) are also designed to increase terrain awareness:  @GulfstreamAero /Honeywell SVS Flight Test
