Aircraft Vertically SeparatedApproaches [VSA] -Takeoffs [VST] and Split-Runway [SR] Operations

Problem l.jpg

  • Airport delays are causing the FAA and Department of Transportation to initiate the reduction of airline schedules and also to consider charging peak hour user fees.

  • New York airport problems are considered to account for about 75% of the nations airline delays and scheduling difficulties.

  • New York’s J. F. K. International Airport is recognized as most critical for delays.

Limitations l.jpg

  • Most large domestic and international airports are locked into expensive real estate, with houses businesses nestled on their borders.

  • Therefore, in most cases, land is not available for new airport construction or for major airport expansion.

  • Even a new runway construction will cost a billion dollars or more, if at all possible.

Solutions l.jpg

  • The inexpensive division of long runways medially, creates two separate and fully functioning runways for B-737, A-320 and EMB-190 type airliners: one for landing - another for takeoff. Since these airliners are the most frequent in flying from JFK and other airports, the Split-Runway, [SR] process provides exactly the same benefit as building an additional new runway.

Faa mandate l.jpg

  • While delays resulting in airport gridlock are limiting the growth of air transportation, especially at New York’s JFK, the only FAA solution is to cut airline schedules and force airlines to pay higher user fees.

  • FAA is also considering auctioning off to the highest bidder, landing slots currently owned by airlines flying in an out of JFK.

Requirements for new generation air traffic system improvements l.jpg
Requirements for New Generation Air Traffic System Improvements

  • Eliminate airport gridlock through SR

  • Use VSA and VST technology

  • Bypass en-route chokepoints

  • Establish Continuous Descent Approaches

  • Establish Jet Climb Corridors

  • Airports provide and pay for ADS-B

  • Airlines equip some airliners for ADS-B

  • Develop RNP approaches & departures

Eliminate airport gridlock l.jpg
Eliminate Airport Gridlock Improvements

  • As an example: divide the JFK 14,571 ft. long runways 13R and 31L medially, than use the approach end as an independent 7,000 ft. runway for landings, and use the 7,000 ft. far end as an independent takeoff runway for B-737, A-320 and EMB-190 type airliners. This will double operations.

  • The full length will continue to be used for ‘heavy’ A-380 and B-747 type airliners.

Are split runway operations ok l.jpg
Are Split-Runway Operations OK? Improvements

  • B-757 airliners, which are considerably larger than B-737 airliners, are currently landing and taking off on Chicago Midway Airport’s 31L and 31R runways, which are only 6,519 feet long.

    Therefore the 7,000 feet Split-Runway [SR] procedures planned for JFK and the other major domestic and international airports are close to 500 feet longer/safer.

New york lga 7 000 ft runways l.jpg
New York LGA 7,000 ft. Runways Improvements

  • Because the FAA approved me to fly 500,000 pound [250 ton] heavy L-1011 airliners from LGA’s 7,000 runways, the FAA cannot logically oppose to implement Split-Runway [SR] flight operations for large 170,000 pound [140 ton] B-737 airliners at JFK by splitting the 14,571 ft. runways into two 7,000 ft. independent landing and takeoff runways.

JFK Runways 4L & 4R Improvements

Washington dca 6989 runway l.jpg
Washington [DCA] 6989 Runway Improvements

  • Washington DCA Airport’s longest runway is 6,989 feet long and handles up to B-757 airline traffic.

  • This is further evidence that the 7,000 feet long JFK Split-Runway [SR] operations are practical, FAA approvable and safe.

  • I have personally flown B-757 airliners from this 6,989 DCA runway.

Faa regulation for low approach l.jpg
FAA Regulation for Low Approach Improvements

  • FAA 3-131 authorizes low approaches to not less than 500 feet above an aircraft in takeoff position on the runway.

  • Since during SR flight operations at JFK, for instance, the takeoff airliner would be on the takeoff runway some 7,000 ft. from an approaching aircraft, this would be considerably safer under FAA 3-131, than current FAA approved low approaches.

Faa same runway separation l.jpg
FAA Same Runway Separation Improvements

  • FAA 3-122 provides in part: “Separate an arriving aircraft from another aircraft . . . (2) the aircraft is airborne, it need not have crossed the runway end if the following minimum distance from the landing threshold exists: [c] When either is a category III aircraft – 6000 feet.”

  • [FAA category III in this case applies to jets.]

  • Since the 7,000 ft. distance of the takeoff runway at JFK is 1,000 feet more than 6,000 ft. required by the FAA - the departing airliner is more than 1,000 ft. beyond the required 6,000 ft. minimum. Therefore, SR runways are in FAA compliance.

Split runway sr safety l.jpg
Split-Runway [SR] Safety Improvements

  • Split-Runway operations will prevent the type of crashes, such as a USAIR B-737 landing on top of an airliner positioned on the end of a LAX runway awaiting takeoff clearance. This cannot happen with SR.

  • Split-Runway operations are unique in that

    these are independent runways, marked as such, and are dispatched accordingly.

Sr implementation policy l.jpg
SR Implementation Policy Improvements

  • Phase One: aircraft cleared into position for immediate takeoff after landing aircraft safely on runway. This phase provides for training and for operational confidence.

  • Phase Two: takeoff to commence when approaching aircraft has landing assured.

  • Phase Three: simultaneous landing and takeoff operations.

Sr requirements l.jpg
SR Requirements Improvements

  • Captain only landings, unless emergency is declared.

  • Prior to SR landing clearance, report of three green, landing gear down and locked must be reported to ATC.

  • Aircraft must be configured for landing prior to final approach fix [FAF] or missed approach must be initiated.

Special sr crew training l.jpg
Special SR Crew Training Improvements

  • Flight crews must have training in SR flight operations and procedures.

  • For all flight operations the avoidance of hydroplaning is essential. Pilots must know the hydroplaning speed and use engine reverse to drop below this speed.

  • 7,000 ft. runway is sufficient under most conditions for B-737 type airliners, still proper braking should be emphasized.

NOT-The-Way Improvements

Split runway sr benefits l.jpg
Split-Runway [SR] Benefits Improvements

  • B-737, A-320 and EMB-190 type SR capable airliners departing JFK, do not have to taxi long distances to the far end of the long 14,571 ft. runway as today.

  • SR operations saves about 700 gallons of jet fuel, reduces crew costs, increases aircraft utilization, eliminates passenger confinement on departing airliners since takeoff sequences are greatly increased.

Vertically separated approaches vsa and takeoffs vst l.jpg
Vertically Separated Approaches [VSA] and Takeoffs [VST] Improvements

  • VSA and VST are offered as a means to reduce approach and takeoff distances between ‘heavy’ and other airliners to the minimum 3 miles of separation required to avoid collision of aircraft in flight.

  • Airliners use Vertical Separation [VSA] & [VST] technology to fly safely above wake turbulence when following ‘heavy’ aircraft.

Vertically separated approaches vsa l.jpg
Vertically Separated Approaches Improvements [VSA]

  • B-737 type airliners on VSA approaches follow heavy airliners 3 miles behind and flying above the wake turbulence land 7,000 feet down on the second half of the Split-Runway.

Vertically separated approaches can also be used by two similar airliners to expedite landings l.jpg

Vertically Separated Takeoffs [VST] Similar Airliners To Expedite Landings

  • The B-737 type aircraft following a ‘heavy’ aircraft takeoff climbs on a minimum 15 degree divergent course to 1,000 feet above the heavy.

Dangerous lax runway incursions l.jpg
Dangerous LAX Runway Incursions Similar Airliners To Expedite Landings

  • Los Angeles International Airport, LAX has continuous runway incursions. LAX is relocating/moving two runways to create taxiways between the two north and also the two south parallel runways.

  • LAX should install colored taxi crossing lights to supplement voice instructions on radio and build Split-Runway crossings.

Bypass en route chokepoints l.jpg
Bypass En-Route Chokepoints Similar Airliners To Expedite Landings

  • Establish the use of INS/IRS, GPS and FMC-offset free-flight for en-route traffic to bypass the presently existing chokepoints on airways.

  • Air traffic with out operating systems to self navigate can be vectored around these chokepoints by ATC.

Create cda and jcc corridors l.jpg
Create CDA and JCC Corridors Similar Airliners To Expedite Landings

  • Continuous Descent Approaches [CDA] and Jet Climb Corridors [JCC] operations take up less airspace, save fuel, create less noise, less controller work load, more

    efficient, cause considerably less airport delays, and are safer by avoiding near miss incidents.

Airports buy and pay for ads b l.jpg
Airports Buy and Pay for ADS-B Similar Airliners To Expedite Landings

  • Airports, especially JFK should buy their ADS-B equipment to eliminate delays.

  • Airlines should equip and dedicate some of their aircraft to fly into these selected and ADS-B equipped airports. This will make it possible for airlines to take advantage of the RNP approach and departure technology.

Conclusions l.jpg
Conclusions Similar Airliners To Expedite Landings

  • If the the Department of Transportation or the FAA had a plan or idea how to solve the airport delays and gridlock, they would not be cutting airline schedules.

  • The break-through Split-Runway [SR] VSA, VST technologies are the only registered possibilities offering hope to resolve these major disruptive problems.
