However, it is perfectly feasible to fly outside of controlled airspace without having to actually speak to anyone. As a general rule, to fly in certain types of controlled airspace, you will need an onboard radio. While it is rare, some aircraft simply don’t have radios installed. Let’s take a quick look at each: – You Don’t Have a Radio in Your Aircraft Two possible scenarios would mean you need to know about light gun signals from the tower. This beacon is non-directional but can still ‘transmit’ different colors to aircraft in the air and on the ground. Some larger airfields will utilize a light beacon located on top of the air traffic control tower. The first is by using a directional lamp, shone straight out of the tower window toward the aircraft. There are two ways in which the tower relays information using light gun signals. Generally, you’ll see light gun signals coming from the tower. However, here at Pilot Institute, we like to make things easy, so you’ll find a handy ‘cheat sheet’ below detailing all of the possible light gun signals in a handy and organized table, along with a detailed guide to light gun signals and possible scenarios when you should look out for them. They also have different meanings depending on whether the aircraft is on the ground or in the air! The light gun signals vary depending on whether they are steady or flashing. There are 3 colors, but 10 different potential messages come because the light signals from the tower can either be steady or flashing. There are 10 different light gun signals that you’ll need to remember. Light guns can emit only one of three colors.Īs the information must be simple and unambiguous, the colors are all in contrast with each other and are easily identifiable.īut, wait, didn’t we say ten potential messages could be relayed to aircraft using light gun signals? Here’s what you need to know… What Colors Can a Light Gun Emit? You can gain vital information if you know them, especially if you are flying non-radio. There are only 10 possible messages that can be relayed to a pilot with light signals from the tower. The good news is that there aren’t that many light gun signals that you need to remember. These signals can either be steady or flashing and have different meanings for aircraft in the air and on the ground. There are 3 different colors of lights red, green and white. Light gun signals are used by ATC to give information to aircraft that are not contactable by radio. But what are they, and what do they mean? Today we will explain everything you need to know about light signals from the tower and even provide you with a handy guide! What Are Light Gun Signals? Light gun signals can be used to relay vital information. Communication in aviation is important, but what do you do if the radio fails? Fortunately, there is an alternative.
