Design philosophy
No matter how efficient a mike or a defender/helmet combination is, inevitably some small amount of the ambient background noise will reach the wearer’s ears through both the mike and the defenders/helmet.
The design of this FH-1V helmet is such that, used in conjunction with any Flycom intercom, the speaker signal and the ambient background noise tend to cancel each other. As a result of this, the volume control acts also as a “noise balance” despite being entirely passive (like ANC but without the added anti-phase signal).
A very noticeable increase in signal-to-noise ratio occurs when the volume is turned down to about half volume or less.

Size guide
Small: 54-56 cm Medium: 57-59 cm Large: 60-62 cm
Note that helmets can be sized down with extra layers of foam fitted under the ‘comfort lining’. As a consequence of the use of Vasco 75H trauma lining, the sizing of the helmet is not critical and will fit perfectly.
General product specification
The helmet utilises the new and acoustically improved Peltor H520F hearing defender (Optime II) fitted with foam and gel ear seals. CE hearing defender noise attenuation certified to standard EN 352-1: Peltor data: (H) 34dB (M) 29dB (L) 20dB SNR 31dB
Our customers tell us that perceived noise reduction of the FH-1V helmet and the Peltor defender is greatly improved compared to defenders of similar type used in open air headsets with cut-away type helmets of other manufacture.
The FH-1V helmet has a noise cancelling electret mike (2k2 ohms impedance) designed to work perfectly with any Flycom intercom and some intercoms of other makes.
FH-1V-GA is supplied with built in 150 ohm mike impedance matching circuitry and separate GA standard mike and speaker jacks on a straight cable GA version for use with GA radios and intercoms. No HA-F/GA adaptor needed.
Detailed specifications of the FH-1V flying helmet
- Glass Reinforced Plastic (GRP) outer shell. Hard wearing trim for superb finish.
- Built-in headset. The non-removable headset is purpose designed and built by Flycom using a Peltor hearing defender with foam and gel ear seals. Please note that his headset does not exist as a stand alone item and is not produced by Peltor.
- Fully enclosed and surrounded by brushed nylon covered foam upholstery inside the helmet blisters.
- No batteries, circuit boards, volume controls, headset cables or mike booms inside or intruding the ear defenders.
- Moisture-proof baffle mounted lightweight speakers set into the defenders’ original acoustic foam lining.
- Roomy defenders. No pressure on your ears- the way the defender was originally designed!
- Mike and speakers as per the Flycom headset.
- Visor is a modified Bob Heath ‘Jet-Flip’ with added HD Polyethylene and Neoprene draught-proof chin guard. The visor is 100% secure and cannot detach accidentally. (It has two security machine screws as well as the three press studs).
- Flexible mike boom with rubber mounted noise-cancelling electret mike. 2.2k ohm impedance.
- Curly lead fully screened terminates in a single 6.35mm (1/4″) three conductor jack. Metal and plastic body, gold plated tip conductor. (Tip = speakers, ring = mike, sleeve = ground).
- Individual water-proof pilot volume control mounted on helmet. (bottom rear left) controlling speaker volume adjustable from max to off.
Comfort and fit
There is no headband inside the helmet. All you feel is the superbly comfortable helmet on your head and the snug fitting defenders with their noise absorbing upholstery round your ears and neck keeping draughts out.
For complete draught-proofing between the flying suit and the helmet the Flycom neck roll NR-1 with a double thickness of heavy polar fleece is recommended. The inner trauma lining of the helmet is Vasco 75H developed for NASA. This lining is super energy absorbing for trauma protection, thermal and sound insulation, comfort and a perfect fit.
The helmet also has a foam-backed nylon jersey upholstery comfort lining and a 4-point riveted chinstrap bridle with easy-adjust strap and quick close/release fastener.
DISCLAIMER
The FH-1V helmet far exceeds all the test requirements in the standard EN 966:1966 and those relevant tests in standard EN 166:2001.
The user should be aware that in real life it is possible to encounter extreme impact and penetration conditions exceeding the test parameters.
Users should be aware that because of its nature, flying is hazardous with or without a helmet and can result in serious injury or death. Noise can damage your health.
NOTE TO SEAPLANE PILOTS
EN 966:1966 does not test the helmet for use in salt water marine environments, nor does it specify or test for any of the communication equipment which may be fitted.
Exposure to sea water can cause metal corrosion and could reduce the life of some of the metal components in this helmet, especially those of an electrical or electronic nature.
Seaplane pilots must ensure that they avoid contamination of the helmet by sea water.
Design philosophy
Eventually almost all fliers need to interface their headsets with a radio and finish up having to plug into an interface box of some sort. Flycom takes the view that this box may as well contain everything you need and be as close to the radio as possible so obviating the need for loads of wires, connections and long patch leads.
Since the box also contains the audio for the intercom as well as the radio, this leaves the headset ear defenders empty to do what they were designed to do, that is, protect your hearing.
The standard EN 966 1996 Helmets for airborne sports (UL) makes reference that provision should be made for the addition of a communication system of some kind. Note, the standard makes no reference whatsoever to decibels, hearing protection, or noise levels; by far the biggest hazard you face when you go flying!

Mk1-BB Product Specification
This Black Box version intercom will interface with any ICOM radio and many others too. It is a superb quality 2-place aviation intercom with crystal clear communication at safe low volume settings. As such, there is no need to crank up the volume on this set (although you can if you want to!).
All Flycom intercoms accept both Flycom Helmets or Headsets with straight or angled jack plugs (both shown) and also GA (twin jack) headset using Flycom Headset Adaptor HA-2. Other key features include:
- Plug-in PTT switch supplied with either coiled lead or straight to order. Remember to specify the length you need.
- Plug-in radio patch lead, fully screened. Standard length 1m. You can have it longer or shorter. (Please state length when ordering).
- Single power supply to intercom and radio as standard.
- Non-radio fliers use without patch lead and PTT for intercom use only. Fused power lead fits in patch lead socket.
- Solo pilots can use the 2-place I/C with P2 unused. Side tone, stall warner and radio communication all still work as normal. P2 socket can be used for music input when flying solo. (Music goes off automatically when you transmit and back on again in receive mode)
- FLYCOM Mk1-BB will interface with either ICOM A2, A20, A3, A22 or A200. State which. (The A2/A20 and A3/A22/A200 patch leads are not interchangeable).
- The FLYCOM Mk1 can be configured to deal with either type of transmission mode and will be supplied with the relevant patch lead.
- Selective audio filtering for optimum voice spectrum. High and low frequencies cut for maximum intelligibility and hearing protection. This is a Lo-Fi headset (by design). The last thing you want in an aviation headset is High Fidelity. see mike waveforms
- P2 mike is mute when P1 transmits on the radio. P2 hears both sides of radio conversation.
- 12v to 13.8v dc supply, polarity protected. FLYCOM Mk1-BB will stand up to 22v max. NB. Your ICOM definitely won’t stand more than 15v!
- FLYCOM Mk1-BB is polarity protected. NB. Your radio may not be!
Optional extras
- Both 3 and 4-place versions available.
- P1 selector switch. (P1/P2 change-over) Determines which socket transmits when the PTT is pressed. Ideal for sharing the radio work without having to swap plugs in the sockets. P2 is mute when P1 transmits. Single or double PTTs. (Note: this is not an option on 3,4 place intercoms).
- Twin plug-in PTTs (For use with change-over relay option COR-1) Enables either radio P1 (right socket) or radio P2 (left socket) to transmit. The other mike automatically mutes during the transmission. Ideal for sharing the radio work or R/T training since P1 (instructor) can override P2 (student) but P2 cannot override P1.
- On-box PTT switch. Momentary toggle or push button action. Please state which. (This can be in addition to, or in place of, the standard remote plug-in PTT).
- Mike output to video or audio tape recorder.
- PTT switch Positive action toggle switch for Trike fliers with Velcro fixing to base bar. Curly lead.
- Warning audio signal. (Available as added circuitry on the intercom circuit board and extra phono socket wired to the plug-in PTT).
When activated the pilot hears a repetitive succession of rapid “bleeps” through the headset. Very attention seeking and cannot be ignored, but quiet enough to allow normal intercom and radio conversations while being activated (Bleeper goes mute during radio transmissions).
The bleeper audio can be used for almost anything on the aircraft which requires an audio warning. e.g. stall warning, low fuel, undone seat belt, unsecured hatch or door, etc. Use your imagination! Simply close the circuit to activate and open the circuit to de-activate. Any normally open (NO) switch or relay wired to a phono plug will activate the warning bleeper when closed.
Mk2B – 3/22 Intercom
Integral intercom and radio in one package! Designed to fit ICOM IC-A3 and ICOM IC-A22 radios
(in place of the NiCad battery) Radio/Intercom packages do not come any neater, better or
cheaper than this!
- Selective audio filtering for optimum voice spectrum. High and low frequencies cut for maximum intelligibility and hearing protection. The helmet/headset is Lo-Fi (by design).
- The last thing you want in an aviation headset is High Fidelity (Hi-Fi)
- Adapters available to accept David Clark or similar GA twin jack aviation headsets for light aircraft.
- Solo pilots can use the 2-place I/C with P2 unused. Side tone, Warning bleeper and radio communication all still work as normal.
- Interference-free. Flycom intercoms will run directly from a ‘Key West’ regulator without a battery in the circuit with no interference! It is, however, recommended that you use a battery with a fuse in the supply lead
- Mk2 fits like a battery pack. ICOM A3 or A22 radios are automatically supplied with power (12 – 15v dc) via the connections on the top of the intercom case.
- Bottom entry sockets for compact installation. (Supersedes Mk2F-3/22 front entry model now discontinued because of new right angled plug options).
- Right-angled plugs now available on helmet/headset leads and extension leads for extra compact installations and universal lead lay-out options. (Front, side even back entry!)
- Mk2 intercoms available separately if you already have an ICOM A3/A22 or older model A2/A20. Available as a package with radio of your choice.
- On-board PTT and remote (plug-in) PTT socket fitted as standard.
- P2 mike is mute when P1 transmits on the radio. P2 hears both sides of radio conversation.
- Ideal for instructors who need to be ‘radio self-contained’ in different aircraft. Besides conventional panel mounting on a bracket they can be carried in a pocket or clipped to a map board or shoulder strap.
- Protection. All Flycom intercoms are polarity protected and will stand up to 22v max.
This intercom does not provide voltage and polarity protection to the IC-A3/22 radios
Single PTT Switches
All Flycom PTT switches can be supplied with either red button switches or momentary toggle switches.
PTT-1C bar-mounted switch with red button and coiled lead. DIN plug fits Mk1-BB intercom. Available with RCA (phono) plug for Mk2 intercoms
Dual PTT Switches
Can be supplied as single coiled cable with 2 switches or 2 coiled cables each with a switch.
Dual PTT switches for dual radio use. One button for Airband radio, one button for PMR radio. Can be supplied with longer interconnecting cable, straight or coiled (between the switches) for use as P1/P2 dual transmission instructor use (requires COR-1 or COS-1 fitted to intercom)
Dual PTT switches for P1 & P2 transmission use. (requires COR-1 or COS-1 fitted to intercom) Here shown with (momentary) toggle switches. Normally supplied with red buttons (as above)
PTT User instructions
Push To Talk, release to listen. The red button switch is maintenance free.
The toggle switch used in this PTT contains sliding metal parts and as such requires occasional lubrication. A light machine oil such as “3-in-1” is recommended. Two or three drops introduced where the toggle enters the body of the switch is sufficient.
DO NOT USE WD40 OR ANY SIMILAR SOLVENT. This will effectively flush out any lubricant and will eventually lead to a sticking switch.
There is a small degree of sideways movement in the toggle. This is not a fault.
SYMPTOMS OF A STUCK SWITCH (continuously transmitting).
- Toggle/button remains in the down position. (unplug PTT from intercom and repair or replace).
- P2 unable to communicate with P1. (P2 mike is mute during transmissions)
- Radio traffic goes quiet. (Other users of the frequency are blocked by your continuous Tx)
Stuck switches are very rare events but not unknown, so it’s best to recognise the symptoms!
PTT-IF-AB interface (paramotor pilot etc)
PTT-IF-AB interface for airband radios with 150 ohm mike inputs like the IC-A6E (A3 and later).
The interface contains circuitry (self powered from the radio, no batteries required) Available with straight PTT cable and/or momentary toggle switch.
It perfectly matches the Flycom helmet or headset to radios with low impedance (150 ohm) mike inputs.
This is suitable for ICOM A3, A22, A6, A24 transceivers. Complete lack of background noise through the mike in standby (Rx) mode.
PTT-IF-PMR interface (paramotor pilot, etc.)
PTT-IF-PMR Interface for old model airband A2/A20 and PMR radios such as IC-4088SR.
Suitable for all radios which accepts an external hand speaker/mike including all PMR or PBR or walkie-talkie transceivers including the older A2, A20 transceivers.
Side tone provided by your radio if available. (No side tone on older A2 and A20 radios).
PTT is a momentary toggle switch for positive action is shown. Also available with red button (see top).
Paramotor customers are advised to order a FLYCOM flying helmet with a short helmet lead.
Please note:
Both PTT interfaces on this page can be supplied with a choice of PTT cable. These can be coiled or straight cables.
Also, there is a choice of hard wired PTT cable or plug-in for easy removal. Both interfaces give complete lack of background noise through the mike in standby (Rx) mode. If your radio provides side tone, this will be heard when you transmit.
Design philosophy
No matter how efficient a mike or a hearing defender is, inevitably some small amount of the ambient background noise will reach the wearer’s ears through both the mike and the defenders. The design of this headset is such that, used in conjunction with any Flycom intercom, the speaker signal and the ambient background noise are out of phase and tend to cancel each other. Because of this the volume control acts also as a “noise balance” despite being entirely passive, just like ANC without the added signal. A very noticeable increase in signal-to-noise ratio occurs when the volume is turned down to about 1/2 volume or less.
HS-1 Headset
The headset utilises the new acoustically improved PELTOR H540A (Optime III) ear defender for state-of-the-art noise exclusion. Each ear defender consists of two cups, one inside the other, separated by special acoustically deadening foam.
