The pilots claim that the LAHSO
procedure, which is designed for intersecting runways to increase airport capacity, has not been adequately tested by the Federal Aviation Administration.
The Allied Pilots Association (APA) and the Air Line Pilots Association (ALPA) have joined forces to recommend that their members do not accept any LAHSO clearance until the FAA has ensured that the procedure is safe to the unions' satisfaction.
A LAHSO clearance means that a pilot agrees to land on a runway and stop before reaching an intersection with another runway so that other aircraft can land or take off at the same time.
AIM 4-3-18.a.9 adds: "Controllers are required to request a read back of runway hold short assignment when it is not received from the pilot/vehicle." We also have 7110.65 2-4-3.b telling controllers, "Ensure the read back of hold short instructions, whether a part of taxi instructions or a LAHSO
clearance." Then, there's the note on the airport diagram as shown on the previous page.
Land And Hold Short Operations: When a landing aircraft must hold short of an intersecting runway.
With intersecting runways, you may be expected to keep your speed high on the roll-out to quickly pass the intersection or the ATIS may tell you to expect to land and hold short (LAHSO
) of the intersection.
Working with a wide range of aircraft, controllers need to know approximate performance figures, such as how fast a Citation climbs or what a Merlin's category is for LAHSO
