FAQs
1. Who is TDG Aerospace?
TDG Aerospace creates dynamic air safety solutions for the aircraft and aerospace industry. Specializing in the development of cutting-edge products that prevent fire and ice, TDG provides solutions that help airlines save money, improve safety, ensure compliance and greatly reduce delays.
2. What is the NOFOD System?
NOFOD is a clear ice prevention system that is designed to prevent the formation of cold soaked wing ice, which accumulates as a result of supercooled fuel chilling the aircraft's upper wing surfaces in above freezing temperatures. The NOFOD Clear ice Prevention system was designed for use on rear engine aircraft and serves as a means of compliance with FAA's Air Worthiness Directive # AD-2002-21-06 (STC SA6042NM).
3. Which major airlines currently fly with the NOFOD system on their planes?
American Airlines, Alaska Airlines, Delta Airlines, US Airways, Aeromexico, Midwest Express, Allegiant and Otter among others.
4. What problem does NOFOD solve?
The FAA has issued an amended airworthiness directive FAA AD 2002-21-06, which is targeted at the MD-80 series and its upper wing ice formation problems. The AD calls for all MD-80 series carriers to either install the TDG Aerospace NOFOD system, the only FAA supported ice-prevention system, or an ice detector by May 2004.
5. What is the difference between an Ice Detector and the NOFOD Ice Prevention System?
An ice detector simply alerts the flight crew that ice is on the wing. At which time, the plane must cease all operations and be grounded and de-iced for an unknown duration. The NOFOD ice prevention system prevents clear ice from ever forming by providing a consistent source of heat to the upper wing surfaces. The NOFOD system eliminates the need to de-ice and enables the flight crew to focus on speedy turnarounds.
6. Can the NOFOD system be used in normal icing conditions?
No, it is only for use in above freezing temperatures
.
7. What is the typical payback on the NOFOD system?
The system pays for itself in 10 to 18 months depending on the operator.
8. When is the best time to install the NOFOD system?
Usually during a C or D check.
9. How long does a NOFOD install take?
Depending on the experience of the MRO, a typical installation usually takes between 480 hours and 900 hours.
10. Who installs the NOFOD system?
Most MROs are capable of installing the system.
11. Is TDG an aircraft parts supplier?
TDG only supplies parts for the systems it manufactures for its customers.
12. What planes is the NOFOD used on?
The NOFOD system is designed for use on rear-engine aircraft, including the DC-9-81, -82, -83, -87, as well as the MD-80 and MD-88.
13. What is the warranty on the NOFOD system?
3 years
14. What is the UFI 3000?
TDG's Universal Fault Interrupter (UFI 3000) is a new product that protects an aircraft's electrical systems and components from electrical faults in critical areas such as fuel pumps, boost pump motors and fuel quantity indicators.
15. Why is the UFI 3000 unique?
Unlike Ground Fault Interruptors (GFI), TDG has developed a new technology that will detect and continuously prevent line-to-line, line-to-ground and arc faults simultaneously.
16. How does the UFI 3000 work?
The UFI 3000 acts immediately upon fault detection by instantly removing power from the affected area and shutting down the circuit before an arc occurs. In addition, the product will assist airlines in complying with SFAR 88 and can be custom-programmed to operate with varying loads and fault detection scenarios.
17. What planes is the UFI 3000 designed for?
The UFI 3000 is currently designed for the Boeing 737 300-500 series. In time it will be designed for many other aircraft and additional electrical systems that need monitoring.
