What it Means if the Aircraft is on the Ground:Ī steady green light directed to the aircraft on the ground means that the aircraft is cleared to take off. This means that the pilot can reasonably expect the runway to be clear without the risk of coming into conflict with another aircraft. What it Means if the Aircraft is in the Air:Ī steady green light directed to aircraft in flight means that the aircraft is cleared to land. You’ll find all of the information summarized in a table at the end of this guide. Here is a detailed explanation of light gun signals for aircraft. Light Gun Signals – All Signals Easily Explained You’ll find detailed information about what these light signals mean below. Fortunately, most of these signals have a common meaning for both ground vehicles and aircraft on the ground. The tower may also use light gun signals to pass information to vehicles or personnel operating at the airport. Do Light Gun Signals Only Apply to Aircraft?Īctually, no. This can either be the aircraft radio that fails or (very rarely) the tower radio.įortunately, the FAA has detailed procedures for when radios fail and what you must do as a pilot. While it is exceptionally rare, two-way radio communication failure does happen from time to time. The Tower or the Aircraft has Suffered a Radio Failure Therefore you will need to know and remember all light gun signals. Interestingly, unless you intend to fly internationally, it is not required to hold a valid FCC radio operator’s license within the USA.Ĭertain airfields will still need to relay key information to the pilot. 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. ![]()
