Are you required to accept a departure procedure?
Are you required to accept a departure procedure? Departure procedures aren't required under Part 91 unless mandated by ATC. However, it's conventional wisdom that you should fly one when it exists. How far do you take that? Is it better to accept a questionable takeoff to fly the procedure or can you ignore it just because you deem it's actually safer to do so?
Are ODP mandatory?
ODPs are recommended for obstruction clearance and may be flown without ATC clearance unless an alternate departure procedure (SID or radar vector) has been specifically assigned by ATC.
Does a Part 91 have to follow the ODP?
“It's true that for Part 91 pilots Obstacle Departure Procedures, or ODPs, are not mandatory. However, when flown correctly, ODPs ensure terrain and obstacle clearance.
What are the two types of departure procedures?
There are two types of DPs, Obstacle Departure Procedures (ODP), printed either textually or graphically, and Standard Instrument Departures (SID), always printed graphically.
Why are departure procedures necessary?
They also use departure procedures for noise abatement. Another reason is so that departing traffic can gain height where there is no inbound traffic (see standard arrival route) so that when they leave the departure procedure, and cross inbound traffic, they are higher.
Do you have to fly an obstacle departure procedure?
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 40 to 1 rule in aviation?
The 40:1 obstacle identification surface (OIS) begins at the departure end of runway (DER) and slopes upward at 152 FPNM until reaching the minimum IFR altitude or entering the en route structure.
