Whether you’re a student pilot or an experienced aviator, having the right gear can make your flights safer, easier, and more comfortable. Below is a list of ten essential aviation items (each under $100) that every pilot should consider. Each item comes with a brief description, why it’s useful, and a link to an example product available on Amazon.

1. Kneeboard (with Notepad or Tablet Holder)

A pilot’s kneeboard is a simple but indispensable tool for cockpit organization. It straps to your thigh and provides a stable surface to hold a notepad, checklists, and even a tablet or charts. This means you can quickly jot down clearances, frequencies, or flight plan changes without juggling loose papers. Every pilot should have pen and paper handy for writing down instructions, and a kneeboard keeps these tools secure and accessible. Many modern kneeboards also double as tablet holders, so you can mount your iPad or EFB device on your leg for easy reference. This is especially helpful in tight cockpits, and it prevents your tablet or notes from sliding around during maneuvers or turbulence. In short, a kneeboard helps you “stay organized in the cockpit”, making it a must-have for efficient flying. Example Product: ASA Visual Flight Kneeboard (VFR) – a sturdy aluminum kneeboard with elastic leg strap and pen holder (around $25). Available on Amazon: LINK

2. Backup Battery Pack (Portable Charger)

Modern pilots often rely on electronic devices like tablets (for charts/EFB apps), smartphones, GPS units, ANR headsets, and more. A high-capacity portable battery pack ensures those devices stay powered throughout your flight. Particularly on long cross-country flights, it’s essential to have a backup power source for your iPad or phone. Losing your electronic charts or communication apps due to a dead battery can be both inconvenient and unsafe. A good aviation battery pack should have ample capacity (enough to recharge your tablet/phone multiple times) and multiple USB outputs to charge several devices at once. It’s effectively a peace-of-mind item: if the aircraft’s power outlets fail or if you fly older planes without USB ports, you’re still covered. Many pilots keep a charged power bank in their flight bag at all times. This also comes in handy for charging devices on layovers or during camping/fly-in events.


Example Product: Anker PowerCore 20,000 mAh Portable Charger – a highly rated power bank that can charge an iPad and phone simultaneously (typically ~$50). Available on Amazon: LINK

3. Non-Polarized Sunglasses (UV Protection)

A quality pair of aviator sunglasses is more than just a fashion statement – it’s important for protecting your vision and reducing glare. In the cockpit, you’ll often be flying directly toward a low sun, above clouds, or through haze, all of which can cause severe glare. A good set of non-polarized sunglasses is considered a “pilot necessity” because without them your vision can be seriously impaired by bright sunlight. It’s generally recommended to choose non-polarized lenses for aviation, since polarized lenses can interfere with reading LCD cockpit instruments or make it hard to see glints from other aircraft. Non-polarized shades still provide full UV protection and comfort, just without the polarization that can darken instrument screens at certain angles. Classic aviator-style sunglasses with UVA/UVB protection are popular because they cover a large field of view and fit comfortably under headsets. They help reduce eye fatigue on long flights and enhance safety by keeping you visually sharp even when flying “into the sun.”


Example Product: Pro Acme Classic Aviator Sunglasses (Non-Polarized, UV400) – an affordable aviator-style sunglass with 100% UV protection and metal frame (around $20). Available on Amazon: LINK

4. Fuel Tester (with Built-in Screwdriver)

Every pre-flight inspection should include sumping the fuel tanks to check for water or contaminants. A fuel tester is a small tube device that lets you draw a fuel sample from the tank drains. The must-have type for pilots is one that also includes a screwdriver or wrench on the cap – this makes it easy to open stubborn fuel drain valves or oil dipstick caps. A fuel tester takes up almost no space in your flight bag, yet “makes all the difference” in ensuring you have clean, proper fuel before takeoff. By inspecting the fuel for water, debris, or the correct fuel grade (color), you can prevent engine issues in flight. The integrated screwdriver tip is useful not only for opening fuel drain knobs but also for quick cowling screws or other small tasks, adding extra utility. Different airports sometimes have slightly different fuel (or could accidentally fuel you with the wrong type), so always testing your fuel is critical. In short, this inexpensive tool helps you verify fuel quality and safety on every flight.


Example Product: Aviation Fuel Tester with Cowl Screwdriver – a sample cup with built-in screwdriver tip in the cap (usually ~$10-$15). Available on Amazon: LINK

5. Dual-Mode Flashlight (White and Red LED)

A reliable flashlight is essential gear for any pilot, even if you don’t plan on flying at night. You never know when you might get delayed until after sunset or have to preflight in the early predawn hours. A good aviation flashlight should have a bright white beam for preflight inspections and an option for red light to preserve your night vision in the cockpit. Red illumination lets you read charts or instruments in the dark without dazzling your eyes or ruining your night adaptation. As one training site put it, “whether or not you go night flying frequently, you want to be sure you have a good flashlight” handy. Many pilots carry two: one small torch in their pocket and a larger one in the flight bag, just in case. Modern LED flashlights are very durable, bright, and efficient on batteries. Look for one with separate switches or modes for white vs. red LEDs – this is ideal so you don’t accidentally flash white light when you intended red. Having a flashlight on board also prepares you for emergencies (like an electrical failure at night or an unlit cockpit). For under $100, you can get excellent compact aviation flashlights or headlamps that fulfill these needs.


Example Product: NITECORE MT20A Dual-Color Flashlight – a compact 2xAA flashlight with both a white LED (high intensity for preflight) and a secondary red LED mode for cockpit use. Available on Amazon: LINK

6. Multi-Tool (Pocket-Sized)

Ask any pilot who’s spent time around airplanes: a multitool is something you’ll use again and again. These are like a toolbox in your pocket – typically including pliers, screwdrivers, a knife, scissors, etc., all folding into one compact tool. Carrying a multi-tool ensures you’re prepared for those little unexpected tasks: cutting a piece of tape, tightening a loose screw in the panel, pulling a cotter pin, opening an oil can, you name it. Many pilots overlook carrying one, but that’s a mistake. In fact, experienced flyers note how often someone else ends up asking to borrow theirs – a sure sign it’s truly useful gear. A multitool can be a lifesaver during an “emergency maintenance stop” at an away airport, or just handy for adjustments and minor fixes on the go. When choosing one, make sure it’s well-built (aviation environments can be tough on cheap tools), yet not so expensive that you’re afraid to use it. The multitool should be kept in your flight bag or on your belt so it’s always within reach. As a nod to pilot culture, one popular choice is literally named “Wingman” – because every pilot needs a good wingman by their side!


Example Product: Leatherman Wingman Multitool – a 14-in-1 stainless steel multitool (spring-action pliers, knife, screwdrivers, etc.) that comes with a belt sheath (around $50-$60). Available on Amazon: LINK

7. First Aid and Survival Kit

While we hope to never need it, a first aid kit is an essential item for any pilot’s gear collection. Small cuts, scrapes, or minor incidents can happen on the flight line or during adventures, so having basic medical supplies on hand is just smart. A well-stocked kit will cover everything from band-aids and antiseptic wipes for minor cuts to more serious trauma supplies for emergencies. In fact, one comprehensive aviation first aid pack has been described as “a Boy Scout in a bag” for its ability to handle a wide range of situations. Being prepared isn’t just about gear – it’s about the confidence to face the unexpected with peace of mind. For this reason, many pilots store a larger survival-oriented first aid kit in the airplane, and maybe a smaller one in their flight bag. Look for kits that are organized (labels or sections for different types of supplies) and that include extras like a multitool or whistle. The Surviveware brand kit, for example, is praised for its “ridiculously organized interior” and high-quality contents covering minor to life-threatening scenarios. In an off-airport landing or remote area, a survival first aid kit could truly save lives. Even on routine flights, it’s great for handling discomforts or injuries on the spot. Don’t fly without at least a basic first aid kit – it’s a must-have for safety and preparedness.


Example Product: Surviveware Comprehensive First Aid Kit – a compact yet well-stocked first aid pack with labeled compartments (approx. $50). Available on Amazon: LINK

8. Carbon Monoxide Detector

Carbon monoxide (CO) is an invisible danger in aviation – an odorless, colorless gas that can leak into the cabin from the engine exhaust and quickly incapacitate a pilot. To guard against this “silent killer,” every pilot should carry a portable CO detector in their cockpit. In recent years, high-quality electronic CO monitors have become very affordable – “now less than a typical hamburger run,” as one AOPA article quipped (pilots often joke about the “$100 hamburger,” so this means under $100). A good portable CO detector will alarm loudly and flash if CO levels rise above safe limits, giving you an early warning to ventilate or land immediately. Some are small keychain-sized devices with digital ppm readouts, others are larger battery-operated units. Either way, this is critical safety equipment. Remember, you won’t smell or see CO, and symptoms of CO poisoning (dizziness, headache, confusion) can sneak up on you – often when it’s too late. That’s why an active detector that beeps at a low threshold (like 35 ppm) is so important. You can find models specifically marketed for aviation, or even a standard home/portable unit works as long as it has audible alarms. Given the low cost, there’s no excuse not to have this lifesaver on board – the NTSB and safety organizations strongly advocate for CO detectors in general aviation planes. In summary: protect yourself from CO with a reliable detector, and you’ll never be caught off guard by a toxic cabin.


Example Product: Forensics Detectors “Travel CO Detector” (Portable Mini) – a pocket-sized digital CO monitor with audible/visual alarms (typically ~$80-$99). Available on Amazon: LINK

9. Handheld Radio or Scanner (Backup Communications)

Imagine you’re flying and your aircraft’s radio fails, or the electrical system dies – how will you communicate with ATC or other pilots? A handheld aviation band transceiver can be a true lifesaver in such situations. These portable radios can tune the aviation frequencies and allow you to transmit and receive independent of the airplane’s systems. Even if you don’t have a full transceiver, a simpler option is a handheld scanner that can at least let you listen to ATC and weather channels. Having one of these in your flight bag means you have a backup way to get information or call for help. In fact, most pilots would be wise to carry one “especially in the event of an emergency”. For general use, many pilots also enjoy using a handheld radio on the ground to monitor tower or ground frequencies before start-up, or to listen to ATIS without running the aircraft radios. When selecting a unit, look for ones that use common batteries (AA battery models are great because you can pack spares that hold long shelf-life). Some models also come with headset adapters, so you can plug in your aviation headset for clearer communication. Note that dedicated aviation handhelds (ICOM, Yaesu, etc.) can be over $100, but there are budget options and used ones that fit under the $100 mark. Alternatively, a scanner like the Uniden Bearcat series, which covers aviation bands, is very affordable. Bottom line: a backup radio is one of those things you hope to never need, but you’ll be extremely glad to have if you ever do need it.


Example Product: Uniden BC75XLT Handheld Aviation Scanner – a 300-channel portable receiver that covers airband (AM) frequencies, letting you listen to ATC and pilots (around $80-$90). Available on Amazon: LINK

10. Pulse Oximeter (Blood-Oxygen Sensor)

If you fly at higher altitudes (even in an unpressurized airplane above

8,000 feet), a pulse oximeter is a smart gadget to carry. This small device clips on your fingertip and measures your blood oxygen saturation (SpO2) and pulse rate within seconds. It’s a must-have for pilots who venture into high elevations where oxygen levels are lower – the oximeter will tell you if your blood O2 has dropped into an unsafe range, which is an early warning for hypoxia. Even if you’re fit and don’t feel symptoms yet, the objective reading lets you know it’s time to use supplemental oxygen. Many modern pulse oximeters are very affordable (typically $20-$30) and have clear LED displays. For “sports/health enthusiasts” like mountain climbers or pilots, these devices are extremely useful for monitoring your status. Some aviation-oriented watches and wearables now include SpO2 sensors (e.g., a certain Fitbit was noted for tracking SpO2 to alert pilots to hypoxia), but a simple finger oximeter can do the job just as well. As a bonus, it’s also handy to have in your first aid kit to check a passenger’s oxygen or pulse during any in-flight illness. In flight training, you might use it to see how you respond to altitude, or even to detect possible CO poisoning (though note: pulse oximeters might give false normal readings with CO – so they don’t replace a CO detector). If you ever plan to fly at night above 5-6k feet or daytime above 10-12k feet, definitely bring a pulse oximeter to stay ahead of hypoxia. It’s a tiny investment for a big safety benefit.


Example Product: Zacurate Pro Series 500DL Fingertip Pulse Oximeter – a top-selling oxygen saturation monitor (reads SpO₂ and pulse in 10 seconds) that is popular among pilots and athletes.

$20). Available on Amazon: LINK
