How to Use a Ground Power Unit to Jumpstart an Aircraft

The process of jumpstarting an aircraft is nothing like jumping a car battery. It’s true there is a battery involved, but everything about the process is different. From the kinds of connections you need, to the requirements for voltage, great care must be taken to ensure the power is transferred properly to the plane. These tips will help you to use ground power to jump an aircraft if you’re ever in the need.

Fixed Ground Power

There are basically two types of ground power unit. The first is a portable one that can be carried out into the tarmac. It’s usually on a trailer of some sort, and it’s often hauled by a small cart or a car that takes it out to the tarmac. The other is a fixed system, where all of the power is centralized before it is  distributed to the aircraft itself. The main power supply must be close to the aircraft itself.

Maintaining Voltage

Maintaining the level of voltage an aircraft needs requires precision. A power unit is capable of supplying too much power, which is why measurement wires are added to the main cable. These wires measure the aircraft’s total voltage, and assist in adjusting the level of output to match the proper voltage. In most cases the magic number is 400 Hz, which is based off old designs that allowed for more compact batteries and electrical units.

The equipment to synchronize the voltage on aircraft isn’t always the most reliable. It’s common for ground teams to employ frequency converters, which do a better job at detecting the problems involved with synching the power systems for an aircraft.

Delivering Power

If the power unit is not close to the aircraft, a portable GPU can be wheeled out onto the tarmac. These units function on diesel, and they are either towed or mounted to a vehicle. Whether the unit is fixed or mobile, bridge mounted devices are attached to the craft where the passengers disembark. Power is transferred over a cable that retracts automatically after the craft has received the jump start. Aircraft power units can require up to four different connectors to properly transfer power from the unit to the craft.

Final Thoughts

Sometimes, airports will use a pit system to charge the power of an aircraft. When pits are used, they must be able to support the weight of the craft that is being serviced. These spaces are confining, so it’s important that crews are able to handle the cables themselves within these tight quarters.

Improvements to Time and Attendance Systems

The technology behind time and attendance systems has changed significantly over the years. Early clocks functioned much like a rotary phone, with later clocks using a card system to record punches. Today’s clocks are almost all digital. This is a huge benefit to employers and employees, who will deal with fewer incidents of time clock fraud and a much smoother process of tracking paid hours.


Today, an electronic time clock can come outfitted with several features that help to cut down on fraud. It’s not uncommon to see clocks utilizing biomechanics to verify an employee clocking in. These systems scan fingerprints, and may have advanced camera systems capable of facial recognition. In fact, facial recognition systems can scan up to 60 different parts of the face in order to verify identity. This technology is also becoming more affordable by the day, and easier to implement. Employees love that they don’t need to memorize ID numbers or carry keys with them, and security is much smoother when everyone is authorized digitally.

Online Attendance

Time clock software now tracks time spent on projects, no matter where the worker may be. The growing age of remote working has created need for employers to track hourly work. These systems not only track attendance, they can sometimes track tasks as well. Employers can download all of this information in easy-to-process time sheets that contain all of the clock punches made by an employee.

New Ways to Clock

Aside from biometrics, there are new ways to clock into a time clock. You can use key fobs that are designed to be used by a single employee, thus enabling security to track who is in which areas. There are also time clocks that utilize RFID technology, allowing employees to keep a card on them for easy access. Portable time clocks offer the features of a stand alone time clock, but they use batteries to make them portable and easy to move. Excellent for companies on-the-go or companies planning a move.

Final Thoughts

Time and attendance are important to focus on. It’s a small component of a successful business, but employees who come to work and do their jobs need to be paid for those efforts. With the new options in time and attendance technology, you will be able to track their efforts wherever they may clock into work from.

Tips for Mobile Advertising

August 7, 2014 by · Leave a Comment 

Mobile advertising is a fairly new form of digital advertising that relies on some techniques that are similar to desktop. You will still find banner and rich media ads, but the sizes and locations will be vastly different. Test different formats to find the ideal ads for mobile.

Ad Hosting

Special care should be taken in figuring out where an ad is actually hosted. Some ads are hosted within a smartphone application, which can present problems when it comes time to track conversions. Other ads are hosted on Web pages, which can present issues if the site isn’t properly scaled to match the mobile experience.

Speed is another issue. File sizes should be kept as low as possible, and you should test your ads before deployment if possible. Internet connections can be an issue, but large file sizes only complicate that problem. Always ask your buy-side platform which sizes are preferred if you need design guidelines.

Ad Formats

It’s helpful to break banner advertising campaigns into ad formats, so that you can easily track which sizes are performing best for your campaigns. Be sure to include individual tracking code for each ad size, and this will help you identify which sizes are most effective.

Final Thoughts

You will find some overlap in the performance of mobile and desktop ads, especially with regards to messaging. However, mobile users are more apt to search by location and may be more likely to buy than to wait for a return phone call.
