## General Aviation Forecasts 2004 – 2015

- 	Jet Airplanes
- Active Fleet			+ 4.9% per year
- Hours Flown 		+ 6.0% per year
- Fuel Consumption  	+ 6.0% per year
- 	Propeller Airplanes
- Active Fleet			<1% per year
- Hours Flown		<1% per year
- Fuel Consumption	<1% per year

## Upgrade from Category B to C

- A “B” runway with significant operations by “C” airplanes is considered to be non-standard
- ANM’s Regional Airport Plan identifies several such sites, however others could soon be affected

## Slide 9

## Upgrade from Category B to C

- RSA & OFA – Longer & Wider
- Runway Gradient - Lower
- RPZ - Bigger
- Taxiway Separation - Wider
- Runway Length MAY increase

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## ALP Development

- 	When developing an airport plan for a B or C runway consider space/land required for Category C standards:
- RSA
- OFA
- RPZ
- Taxiway separation

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## Runway Design

- 	When developing a Category B or C runway design, consider Category C Longitudinal Gradient
- Design existing length to be “extendable” to a C gradient, without causing a line-of-sight problem

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## Runway Length for B vs C

- 	Runway extension is not necessarily required
- Length can be based on groups of airplanes (by general size) or specific airplane characteristics
- Length is a function of Performance, Load etc.

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## FAA Planning Guidance

-  	Best Practices: Planning Airports for Business Jets
- Will be included as an appendix in the new Master Plan A/C

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## Declared Distances

- 	Meant to address “Non-Standard” Conditions
- Specifically RSA, OFA and RPZ
- 	Not intended to increase runway length
- 	Intended for “existing constrained airports” where it is “impracticable to provide standard RSA, OFA or RPZ”

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## Declared Distances

- Published for pilots to use in computing take-off and landing distances: i.e.
- TORA is “Length of runway suitable for takeoff run *computations**”*
- TODA shall not exceed the runway length plus clearway, but *usable* TODA is determined by the pilot

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## Declared Distances

- 	Two RPZ’s required to be shown on ALP
- Approach RPZ – starts 200 feet before the threshold
- Departure RPZ – starts 200 feet past the end of the TORA
- 	Should be shown on all sheets that include the RPZ including the Property Map

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## Declared Distances

- 	ANM ALP Checklist says:
- Include DD information on the main ALP drawing
- Add a separate drawing for DD’s if needed to show appropriate details

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## Modifications to Standards

- 	Can be reviewed and approved prior to or
-     during the ALP review process
- 	Recommend informal review with ADO
-     before ALP review process
- 	Northwest Mountain Region ALP Checklist:
- List all approved Modifications on main ALP sheet including approval dates

- FAA Northwest Mountain Region Airports Conference - Seattle   2004

## Modifications to Standards

- 	Justify Acceptable Levels of:
- Safety
- Economy
- Durability
- Workmanship
