Headsets (4)

Aviation headsets are worn by pilots and will always have a microphone and be designed for good noise reduction. Lowering the volume of engine, airflow and blade noise is important to protect pilots from loss of hearing. Microphones allow the pilots to communicate with the ground, air traffic control and with others in the aircraft, co-pilot or navigator.

ANR stands for Active Noise Reduction, where a microphone picks up the external noise and a mirror of the sound is created electronically and played back out to the ear cups. This effectively cancels out the external noise. It can be extremely effective at removing ambient sounds creating a very clear headset for pilots, protecting your hearing from engine noise. They are design to cancel low frequency sound, so speech, engine noise changes and airflow are easily picked up. They are generally smaller and lighter than pnr headsets therefore can be more comfortable.

PNR or Passive Noise Reduction headsets use noise absorbent foam to absorb sound and gel seals along with a more clamped fit to create a seal around the ears to protect from damaging noise. So these headsets are more about sound proofing.

Choice usually come down to personal preference. PNR will give a good level of protection while still keeping the pilot connected to the aircraft. ANR tends to be more expensive because of the technology that goes into them. It may also help to consider the environment that you will be using them in and the level of noise that you are exposed to.

We stock a wide range of ANR headsets and PNR headsets.

Electret microphones which are high impedance and require a drive voltage to operate. Electret microphones are very sensitive and often contain a noise-cancelling circuit to reduce background noise. Standard GA headsets use electret microphones

Dynamic microphones are low impedance. They are not sensitive and usually only pick up noise within a few inches of the microphone so they tend not to pick up wind or engine noises and are ideal for noisy or open cockpit aircraft. Military headsets use dynamic microphones but the intercom or radio needs to have a special amplifier to be able to use them.

Dynamic microphones can be used on standard GA systems when a special amplifier is used.

We stock Binder-7, Fischer, LEMO, Twin GA, US NATO and XLR-5. It is easy to see which headset comes with each plug, just go to our Aviation Headsets section and use the filters on the left to select your required plug. You will then see all the headsets available with that plug.

Icom IC-A25 (1)

The Icom A25 radio replaced the A6 and A24 models.

The CE version is a COM transceiver only and the NE version also has a VOR/LOC receiver and a bluetooth headset interface built-in.

Both units have the same radio features and take the same accessories.

These units come in two packages – SPORT and PRO.

The SPORT package comes with an Alkaline battery case, aircraft power supply, antenna, belt clip and handstrap.

The PRO package includes a rechargeable Lithium battery instead of the alkaline case, a desktop mains fast charger and a GA headset adaptor.

Electronic flight Instruments (3)

The Primary Flight Display (PFD) is an instrument which integrates and depicts, on a single display, all of the information that was historically presented on a number of individual electromechanical instruments. The PFD has evolved from a basic attitude indicator/flight director combination, presented electronically on a CRT, to an Electronic Attitude Direction Indicator (EADI) which, variable by manufacturer, added additional information such as heading, altitude and airspeed.

The modern PFD displays virtually all of the information that the pilot requires to determine basic flight parameters (altitude, attitude, airspeed, rate of climb, heading, etc) plus autopilot and auto-throttle engagement status, flight director modes and approach status. Depending upon the phase of flight and pilot selections, the flight director will provide appropriate lateral guidance to maintain the selected track, heading or approach and missed approach track and vertical guidance for climb and descent, level off, approach and missed approach. This greatly reduces pilot workload while in manual flight and facilitates flight monitoring with the autopilot engaged as all required information is displayed on a single instrument. Skybrary

An Electronic Flight Instrument System (EFIS) is a flight deck instrument display system in which the display technology used is electronic rather than electromechanical.

A typical EFIS system comprises a Primary Flight Display (PFD) (Electronic Attitude Direction Indicator (EADI)) and an Electronic Horizontal Situation Indicator (EHSI) (Navigation Display). In some designs the two displays are integrated into one. Skybrary

The Electronic Horizontal Situation Indicator (EHSI), often referred to as the Navigation Display (ND), replaces a number of different instruments found on a conventional aircraft instrument panel, and may be used to depict some or all of the following information:


plus much more information according to design.
