BLOCKALLS IFR View Limiting Device: The Evolution of Instrument Training

What is the BLOCKALLS IFR View Limiting Device and how does it work?

BLOCKALLS are ultra-light training shades for instrument flight practice. The precisely engineered eye openings give a clear view of the instrument panel while blocking the outside view, so the pilot flies by reference to instruments alone. This simulates instrument conditions for effective IFR proficiency training and offers superior glare reduction compared with standard white or frosted alternatives.

How are BLOCKALLS different from foggles or a traditional hood?

BLOCKALLS are worn like lightweight shades rather than a bulky hood, weighing less than an ounce for a barely-there feel. Compared with standard white or frosted foggles, they offer superior glare reduction, blocking distracting sunlight. The precisely engineered eye openings keep your view on the instruments while blocking outside references, and they slide easily under headset seals.

How much do BLOCKALLS weigh and are they comfortable for long flights?

They weigh less than an ounce and are 30 percent lighter than the original design, giving a barely-there feel that helps eliminate the fatigue and pressure points common with traditional devices. An ergonomic rubber nose cushion provides lasting comfort on long cross-country training flights, and the ultra-light frame is built for extended instrument sessions.

Do BLOCKALLS work with aviation headsets?

Yes. This device is designed to work with all standard aviation headsets. The redesigned smaller, thinner bayonets and streamlined side arms slide easily beneath the headset ear seals, helping maintain the seal for good noise reduction. That lets you put them on and take them off without removing your headset during a training flight.

Are BLOCKALLS acceptable for instrument training and the practical test?

BLOCKALLS are an FAA-compliant view-limiting device built for instrument training. View-limiting devices are the standard tool for practicing flight solely by reference to instruments. Always confirm acceptability with your flight instructor or examiner and your training program, since they set the specific requirements for lessons and the practical test.

Do I need a safety pilot or instructor to use BLOCKALLS?

Yes. A view-limiting device is meant to be worn only while another qualified pilot keeps watch outside, and it is not for single-pilot use. You must have an appropriately rated safety pilot or flight instructor on board. That second pilot watches for traffic, terrain, and weather while you fly by reference to instruments alone.

Is there a separate BLOCKALLS version for a flight instructor?

Yes. Alongside the standard pilot version, BLOCKALLS offer a dedicated CFI version intended for the flight instructor in the right seat. Choose the model that matches your seat and role so the clear viewing area lines up with the panel. Most instrument students will use the standard version for left-seat training.

Is there a BLOCKALLS version made for helicopter training?

Yes. BLOCKALLS offer a dedicated helicopter version built specifically for rotorcraft instrument practice rather than fixed-wing flying. If you train in a helicopter, choose that model. Fixed-wing pilots should select the standard pilot version, or the CFI version for a right-seat instructor, to match their aircraft and seat.

What colors and lens options are available?

BLOCKALLS come in several frame and lens choices, including Black Clear, Black Tinted, Red Clear, Silver Clear, Blue Clear, and Green Clear, plus dedicated CFI and Helicopter versions. Clear lenses suit most training, while the tinted option adds extra glare reduction. Pick the color and lens that fit your cockpit lighting and personal preference.

Can I wear BLOCKALLS over prescription glasses?

No. BLOCKALLS cannot be worn over prescription glasses. If you normally fly with corrective lenses, talk with your flight instructor about a view-limiting option that accommodates eyewear, such as a hood-style device, before your training session so your instrument practice is not interrupted.

Who designs BLOCKALLS?

BLOCKALLS were designed by pilots based on real-world input from across the aviation community. The newest generation was engineered to be lighter, sleeker, and more comfortable than the original, with the goal of supporting safer and more effective instrument training. The result is a refined view-limiting device tuned to the demands of the modern cockpit.
