what is a diverse departure, check these out | What is a diverse departure assessment?

If an aircraft may turn in any direction from a runway within the limits of the assessment area (see paragraph 5-2-9e3) and remain clear of obstacles, that runway passes what is called a diverse departure assessment and no ODP will be published.

What is a diverse departure assessment?

A diverse departure assessment ensures that a prescribed, expanding amount of Required Obstacle Clearance (ROC) is achieved during the climb-out until the aircraft can obtain a minimum 1,000′ ROC in non-mountainous areas or a minimum 2,000′ ROC in mountainous areas.

When would you choose to do a diverse departure?

When would you choose to do a diverse departure and how would you perform it? If an airport has at least one instrument approach, and there are no published IFR departure procedures (no penetrations of the 40:1 OIS), then an aircraft departing IFR can ensure obstacle clearance by executing a Diverse Departure.

How do you fly a diverse departure?

If you fly a diverse departure, you must reach a known safe instrument altitude before getting more than 25 nm (or 46 nm in the mountains) away from the airport.

What are departure procedures?

Departure Procedures are pre-planned terminal instrument flight rule (IFR) procedures, designed for two reasons: The primary purpose is to provide obstacle clearance protection information to pilots.

Do I have to fly a SID?

Pilots must immediately advise ATC if a different RNAV SID is entered in the aircraft’s FMC. When this advisory is absent, pilots are still required to fly the assigned SID as published.

Do you have to use a SID?

Usually VFR pilots will be given radar vectors corresponding to the SID lateral route with different altitude restrictions. Pilots must follow the published SID route, unless otherwise directed by an Air Traffic Controller.

Do you have to fly ODP?

Obstacle departure procedures are not mandatory unless of course, it was included with the ATC clearance. Typically the ATC clearance will not include the ODP unless the controller assigns it for separation. It is the pilot’s responsibility to avoid obstacles until at or above the minimum vectoring altitude.

What is the purpose of a SID?

A Standard Instrument Departure Route (SID) is a standard ATS route identified in an instrument departure procedure by which aircraft should proceed from take-off phase to the en-route phase.

What is the 40 1 rule?

The typical objective is to provide at least 48 feet per nautical mile of clearance above what’s known as the obstacle clearance surface (OCS), an imaginary surface that rises at a 40:1 ratio—this equates to a slope rising at a rate of 152 feet per nm.

What altitude can you turn after takeoff?

It is recommended that takeoff power be maintained until reaching an altitude of at least 500 feet above the surrounding terrain or obstacles. The combination of VY and takeoff power assures the maximum altitude gained in a minimum amount of time.

What are some of the differences between SIDs and Odps?

Pilots must have at least the textual description of the procedure. SIDs always have a graphical depiction. Unlike Obstacle Departure Procedures, SIDs usually have portions where the altitude is restricted—either minimum or maximum. Most SIDs have multiple transitions to get you into the en route system.

What do helicopter pilots say when taking off?

“Fly heading two three zero, Runway two seven Left, Cleared for takeoff” (After takeoff, fly a magnetic heading of 230º. Cleared to takeoff on Runway 27 Left) “Cleared for the ILS, runway three four” (follow the Instrument Landing System, an electronic guidance system, to runway 34)

What to say to ATC when taking off?

Simply call on the frequency you are given, state your call sign and position, and the words “request flight following.” If the Center controller can work you, he’ll give you a transponder code and information on other radar-identified traffic around you.

Where are departure procedures located?

ODPs are usually depicted in text, not graphic, format and are located in the front of the NACO chart book and on the bottom of the airport information page in Jeppesen’s.

Can you decline a SID?

If the SID requires equipment you don’t have installed, then you should decline it by saying “unable”.

What is a star in aviation?

Standard Terminal Arrival (STAR) Procedures

A STAR is an ATC coded IFR arrival route established for application to arriving IFR aircraft destined for certain airports. STARs simplify clearance delivery procedures, and also facilitate transition between en route and instrument approach procedures.
