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.
A floatstick is a device to measure fuel levels in modern large aircraft. It consists of a closed tube rising from the bottom of the fuel tank. Surrounding the tube is a ring-shaped float, and inside it is a graduated rod indicating fuel capacity. The float and the top of the rod contain magnets.
Fuel-injected engines do not have this control. For fuel-injected engines, a fuel boost pump is used to prime the engine prior to start. Fuel quantity gauge - Indicates the amount of fuel remaining in the identified tank. One per fuel tank. Some aircraft use a single gauge for all tanks, with a selector switch that can be turned to select the ...
EICAS typically includes instrumentation of various engine parameters, including for example speed of rotation, temperature values including exhaust gas temperature, fuel flow and quantity, oil pressure etc. Other aircraft systems typically monitored by EICAS are for example hydraulic, pneumatic, electrical, deicing, environmental and control ...
A single-engine piston aircraft has a simple fuel system; a tanker (such as the KC-135), in addition to managing its own fuel, can also provide fuel to other aircraft. [1] Fuel is piped through fuel lines to a fuel control valve (usually known as the fuel selector). This valve serves several functions. The first function is to act as a fuel ...
For an aircraft engine, changes in airspeed or altitude cause changes in air speed and density through the engine, which would then have to be manually adjusted for by the pilot. A fuel control unit attempts to solve those problems by acting as an intermediary between the operator's controls and the fuel valve.
Aero Engine Controls is the former name of Rolls-Royce Controls and Data Services.The company produces engine control software, electronic engine controls (EEC), fuel metering units (FMU), fuel pumps and engine actuators for a large number of common commercial and military aircraft. [1]
For example, Concorde cruised at 1354 mph, or 7.15 million feet per hour, with its engines giving an SFC of 1.195 lb/(lbf·h) (see below); this means the engines transferred 5.98 million foot pounds per pound of fuel (17.9 MJ/kg), equivalent to an SFC of 0.50 lb/(lbf·h) for a subsonic aircraft flying at 570 mph, which would be better than even ...
