Touchdown

The Touchdown Set-Up Be prepared for any last-minute corrections when landing By Peter Katz ...

Touchdown means selecting the touchdown spot. Usually we try to select an area in the last 1/3 of the LZ because this makes our approach angle shallower, and increases the chance of us making the landing zone if the engine quits on short final.

TOUCHDOWN [ICAO]- The point where the nominal glide path intercepts the runway. NOTE: Touchdown as defined above is only a datum and is not necessarily the actual point at which the aircraft will touch the runway. TOUCHDOWN RVR- ...

Touchdown Zone Lighting (TDZ) - A system of two rows of transverse light bars located symmetrically about the runway centerline, usually at 100-foot intervals and extending 3,000 feet along the runway.

At touchdown and thereafter, the airplane should be sufficiently well centered that the centerline is between the main wheels. On a narrow runway you have no choice, but on a wide runway you should land on the centerline anyway.

The touchdown and subsequent ground roll after which the aircraft is turned off the landing area at an appropriate taxiing speed.

TDZL touchdown zone lights. TECHNICAL STANDARD ORDER (TSO) A performance specification and production compliance criteria applied to avionics and defined by FARs and the RTCA.

To successfully perform an autorotative landing, the pilot must reduce airspeed and rate of descent just before touchdown.

Slow descent and forward speed in anticipation of touchdown Your landing distance is the total distance required to clear an imaginary 50-foot high screen at the beginning of the airstrip ...

Although the localiser signal would be present throughout the landing, the glideslope had to be disregarded before touchdown in any event.

Public or private, the soft touchdown virtually guaranteed by grass will impress your passengers, while taking you back to a simpler time in the history of flight. Pilot Controlled Lighting ...

an outer marker, a radio beam 4 to 6 miles from the touchdown point where the electronic signal begins; 2. an approach lighting system at the runway end; 3. a localizer radio beam which provides the horizontal guide; and 4.

Flare The point during the landing approach in which the pilot gives an increased amount of up elevator to smooth the touchdown of the airplane. Flight Box A special box used to hold and transport all equipment used at the flying field.

The localizer guides the aircraft toward the centerline of the runway, while the glideslope acts as a ramp to a designated touchdown area on the runway. The pilot uses a CDI to "see" both the localizer and the glideslope.

FLARE - A maneuver performed moments before landing in which the nose of an aircraft is pitched up to minimize the touchdown rate of speed.

Flight Time That portion of the trip actually spent in the air. For billing purposes this definition is generally strict and only applies from moment of liftoff to moment of touchdown.

FLAPS — Hinged surfaces on the inboard rear of wings, deployed to increase wing curvature (and thus, lift), primarily used to control angle of descent and to decrease landing touchdown speeds.

use instruments to see where their aircraft is in relation to the projected centreline of the runway (even if they can't actually see the runway itself), and in relation to the ideal 'glideslope' - an 3° descent path projected up from the touchdown ...

A smooth touchdown in a simulator is about as exciting as kissing your sister. A helicopter is a collection of rotating parts going round and round and reciprocating parts going up and down - all of them trying to become random in motion.

Intermeshing rotors cause pronounced pitch attitude change in response to collective pitch change, The K-Max tailplane is connected to the collective to alleviate this problem as well as to reduce blade stresses and to produce touchdown and lift off ...
