Key Features


Designed for Setting Your Base or Installation to Support Custom Earmolds for Aircrew and Ground Personnel

The techniques taught support the war fighter in the air and on the ground. The skill set learned will provide custom ear impressions that are accepted by a variety of companies in support of Custom Ear Molds. Students will learn how to do the ear impression, support the ordering process, and support the final product once it is in your aircrew or ground personnel’s possession.

Customized Schedule and Lowered Cost for Training

This course is taught at your location to drive down the total costs for training and allow your organization to customize the schedule while also allowing a large amount of personnel to get trained. The costs of the course are for travel, lodging, and per diem of the instructor. The materials bought to support the training and initial ear impression taking of your customers are based on the number of individuals being trained and expected impressions needed to be made for initial outfitting of customer ear molds. The materials can be purchased using Government Purchase Cards, as well as, the Instructor Services. We work with you to tailor training for your needs at your location to include the duration of the training as long as the instructor gets 8-total hours of instruction and evaluation of your designated ear impression taking personnel.

Continued Support

Pro Flight Gear provides continued support of your Ear Impression collection. Your trained students will be provided an open dialogue with our trained professionals to help with any issues or to refine the ear impression process. We will ensure that your base or installation has trained experts in the Ear Impression Taking and Management of a Custom Ear Mold Program.

Advantages of Bringing the Training to You

The Instructor comes to you for training. The materials needed for instruction are to be purchased by the Operations Group using Cost Per Flying Hour Funds as you are supporting their air crew by training in this skill. There is not a cost per student, but if there are more than six students, Pro Flight Gear needs to bring two instructors to ensure proper oversight and support for complete training.

Cost Estimates of Training


Travel is based on the following –

  • Airfare (if a drive is more than an 8-hour driving radius from Nashville, Tennessee)
  • Car Rental (local airport if flying or Nashville Car Rental Rates if driving; roundtrip with travel the day before and the day after training.

Lodging and Per Diem:

The lodging and per diem is based on the current Fiscal Year rates for the location of the training. Full Per Diem is expected on travel days regardless of method of travel.

Instructor Hours:

The instructor hours are based on an 8-hour course at $75.00 per hour. If a second instructor is required, their rate as a technician is $55 per hour for the same course length.

Student Expectations:

The students need to be dedicated to the course duration and not working other duties while taking the course. Students will be provided with the materials necessary to practice and continue to remain proficient at the tasks.

Post-Course Support:

After the course is complete, Pro Flight Gear will continue to work with graduates of the course to support any technical help they need, as well as, support in their certifying of new ear impression takers.


Cost Estimates of Materials Needed for Course

Pro Flight Gear will coordinate with the organization requesting training to determine what materials will be needed and at what volumes. The materials will cover the training and certification of course attendees as well as initial support of aircrew at the location of the training. Materials can be purchased through Pro Flight Gear or with coordination the organization can purchase from other manufacturers as long as the materials are compliant with the SEIT Course and Impression Taking Requirements.


What Sets PACE Apart from Other In-Ear Comm Systems?

PACE is similar in format to other in-ear communication systems; however, PACE is designed to route the communication cable over the ear and behind the neck, with the connection point on the flight helmet versus the oxygen mask. This configuration improves both egress and ejection safety and should reduce the cost of transitioning standard fixed-wing flight helmets and masks to PACE.


The PACE design is lower profile and uses a much more robust stereo connector instead of the SMB coaxial connector used in other comm systems for rotary-wing aircraft. The overall construction of the PACE cable is more rugged with more responsive earphone speakers for improved communication clarity. The PACE cable is built to last much longer than similar products.


The PACE custom earphone tips provide more comfort with a smaller pressure vent to allow for better noise attenuation (the amount of passive noise reduction), with a connection point and speakers that are true stereo. In addition, PACE allows a single cable to be used on all aircraft platforms and can be used with either non-custom tips or custom tips. The ability to use a single cable for all aircraft and to accommodate the use of custom or non-custom earphone tips improves operational requirements while reducing costs and increasing efficiency.

What Is the Process for Submitting My Ear Impressions?

Once you have had your impressions taken, make sure you complete an impression slip and send the slip to the lab with your actual ear impressions.

  • If your unit or organization gives you a pre-labeled envelope, put your impressions and prepaid slip in the envelope and mail that off to the address listed on the front. This will cover the shipping cost to and from the lab.
How Do I Fill Out the Impression Slip?
  • Fill out your name, organization or unit, color selection per ear, earpiece style, vent selection, contact and shipping information. This will help us identify your order, and who to contact and ship it back to.
What’s the Expected Timeline to Receive the Custom Earpieces Back?
  • Estimated timeline is 3 weeks from the time the shipment arrives at the lab and the ear impressions are approved for production.
How Do I Know Which Ear the Custom Earpieces Go In?
  • A red dot is placed at the base of the canal of the right earpiece. The earpieces will also only comfortably fit into the correct ear.
I Got a PACE Kit from Supply/ Aircrew Flight Equipment/ My Unit. How Do I Pay For my Custom Earpieces?

Included in each PACE kit is a clear baggie, a pre-labeled envelope, and an impression slip with an order number stamped on it ( the number should start with either the last two digits of the year or a long contract number that includes letters and numbers).

  • YES – The custom earpieces are already paid for.
  • NO – If the contract slip is missing, please contact the individual that gave you the slip or contact sales@proflightgear.

If you were not provided the contract slips due to unit/organization policy – then you will contact sales@proflightgear to order your custom earpieces directly from us.

What Is Included In the PACE Kit?

We have different types of PACE Kits, so it will depend on which one has been ordered or purchased, but it should have the following:

  • Pre-labeled Envelope
  • Clear Baggie
  • Impression Slip with an order number starting with the last two digits of the year or a contract with letters and numbers included
  • Standard cable (only in the PFG-PACE-1001-Cust Kit)
