## What is reference point in aviation?

The designated geographical location of an aerodrome, located near the initial or planned geometric centre of the aerodrome and normally remaining where originally established.

## What is ARP in aviation?

The Airport Reference Point (ARP) is the approximate geometric center of all usable runways.

**How is aircraft ACN calculated?**

The procedure to calculate the ACN is as such: Design a theoretical pavement according to a defined criterion: For flexible pavements, design the pavement for 10,000 load applications of the aircraft according to the CBR design procedure combined with Boussinesq’s solution for deflection in the elastic half-space.

**What is aerodrome traffic density?**

Aerodrome traffic density means the number of movements in the mean busy hour and is the arithmetic mean over the year of the number of movements in the daily busiest hour.

### Can you fly through an ATZ?

An aircraft must not fly, take off or land within the ATZ of an aerodrome unless the commander of the aircraft has complied with paragraphs 2, 3 or 4 as appropriate.

### Can ACN exceed PCN?

An aircraft having an ACN (at a given weight) equal to or less than the PCN can operate without restriction on the pavement, provided that its tire pressure does not exceed the PCN limitation.

**What is Airport Reference Point (ARP)?**

The Airport Reference Point (ARP) is the approximate geometric center of all usable runways. The ARP position computation is somewhat similar to a center of mass computation, except that only two dimensions are considered

**Where is the reference point for an aerodrome?**

2.2.1 An aerodrome reference point shall be established for an aerodrome. 2.2.2 The aerodrome reference point shall be located near the initial or planned geometric centre of the aerodrome and shall normally remain where first established.

## What if the waypoint in the GPS is the airport reference point?

If the waypoint in the GPS is the airport reference point, such as might happen on a VFR approach at night or in compromised visibility to an airport without a published approach, you must remember there can be a slight divergence in track and bearing as you get close to the runway.

## What is the official location of an airport?

A point on the airport designated as the official airport location. It is generally indicated in six-digit coordinates.
