Land and Hold Short, Kimosabi

Hi-yo Silver!

In this week’s show we are going to saddle up with the Lone Ranger and break out a lasso, I mean, LAHSO. I know, we should quit horsing around and get down to business.

We’ve got masked heroes on horseback; we’ve got fireworks and exploding software; we’ve got your question of the week. I ask you, where else can you go for such fired-up enthusiasm over something as routine as talking on the aircraft radio. Right here, that’s where. Hi-yo Silver! Away!

Show Notes:

  1. Here’s hoping for a speedy recovery for all those who were injured in the crash of Asiana Airlines Flight 214. It’s tragic that 2 people died in the crash and 168 people were injured. Focusing on the positive: It is impressive that the flight attendants were able to guide the evacuation of more than 300 people from the Boeing 777.
  2. There is a complete replay of the San Francisco Tower radio communication during and after the Asiana Airlines crash. You can find a link to it at my Twitter feed. Go to Twitter.com/atc_jeff. If you have not already signed up for my Twitter feed, you can do so by clicking the Twitter icon in the upper right margin of ATCcommunication.com.
  3. ATC’s Land and Hold Short (LAHSO) program is designed to improve traffic flow at busy tower-controlled airports. When used, it allows air traffic control to land aircraft on a runway and slow to a stop or exit the runway prior to reaching a designated intersection.
  4. When an aircraft lands and holds short of an intersection, it allows ATC to cross other airplanes through that intersection without concern for a traffic conflict with the landing aircraft.
  5. You do not have to accept a LAHSO clearance if you are not familiar with the LAHSO procedure or the airport layout, including any signs, runway markings, or lighting associated with the procedure.
  6. The FAA’s Airport Facility Directory lists information on an airport’s LAHSO program, including the runway affected, the land and hold short point, and the available landing distance measured from the runway’s threshold to the hold short point.

  8. You also do not have to accept a LAHSO clearance if either you or your aircraft is not capable of stopping prior to the intersection named in the LAHSO clearance. To make this determination, you have to know how much runway distance is available from the threshold of the runway to the intersection you are expected to hold short of.
  9. If you are familiar with the LAHSO procedure for the runway in use, and if you and your airplane are capable of stopping prior to the named intersection, you should accept the LAHSO clearance.
  10. Once you accept a LAHSO clearance, you are required to comply with the clearance unless you are able to get an amended clearance prior to landing.
  11. A LAHSO clearance will include a clearance to land and the words, “Hold short of,” along with the runway, taxiway, or point you are expected to hold short of.
  12. Compliance with a LAHSO clearance does not necessarily mean you will land and stop on the runway prior to the named intersection. It only means you will not cross through that intersection. It is perfectly acceptable, and usually expected that you will slow to a safe taxi speed and exit the runway prior to intersection named in the LAHSO clearance.

Your Question of the Week:

You are on a 7-mile final approach to Runway 22 at a tower-controlled airport. The airport’s ATIS broadcast said Land and Hold Short Operations are in effect for Runway 22. You are flying a large aircraft that requires a minimum runway length of 4,700 feet for landing. Runway 22 is longer than 4,700 feet. The tower controller says to you, “November 338 Golf Lima, Runway 22, cleared to land. Hold short of Taxiway Charlie.”

You know there was a LAHSO program published for this runway because you read about it in your preflight planning session. You also learned in your preflight study that the available landing distance on Runway 22 from the threshold to the intersection of Taxiway Charlie is 4,400 feet.

Here’s your question. What is the radio transmission you would make in reply to Tower’s clearance?

When you think you know the answer to the question, go to ATCcommunication.com/answers.

New Day, New Jet

"New day, new jet." That is an Air Force Instructor Pilot's standard statement that means the current training scenario is over, and a new one has begun. It is a line of demarcation that reminds student pilots it is time to move on to the next challenging scenario. It's a new day here at ATCcommunication.com,

Flying into Class B for the First Time

If you are anticipating flying into Class B airspace for the first time, not to worry. The procedures ATC uses inside of Class B are nearly identical to those used in other classes of airspace. The subtle variations in procedure will most likely be unnoticeable to you. What may jump out at you is the

Pilot’s Discretion Descents

As you approach your destination, ATC will clear you to begin a descent from your enroute altitude to some lower altitude. Often descent clearances will come in a series of lower altitudes. This series of step-down clearances is issued to allow you to descend without conflicting with other traffic at lower altitudes. Occasionally, and in

I Hate Holding

No one likes to have their forward progress stopped. You know what I mean. When you are stuck in a traffic jam on the road, it’s very aggravating. Waiting at a long red stoplight when you need to be somewhere can raise your blood pressure. Similarly, when ATC says, “Expect holding at [a navigation fix],”

Coping with Busy Airspace

The time between ATC’s radio transmissions differs depending on the amount of traffic in a controller’s airspace. The more traffic in a section of airspace, the less time between ATC transmissions. Take comfort in the fact that no matter how busy the radio seems, the words and phrases ATC uses remain exactly the same words
