IFR- Obstacle Departure Procedure
Asked by: Dan Chitty 3277 views Airspace, FAA Regulations
Regarding the GRZLY TWO DEPARTURE (KMSO) Missoula, Montana, I am interested to get clarity with the climb in visual option.
NOTE: The “standard” option instructions are quite clear in my opinion.
Runway 11: Cross MSO VOR southeast bound at or above 5800 southeast bound------Does this mean to fly directly over (“cross”)the VOR at or above 5800 as soon as partible after takeoff ? . It seems that flying over the VOR immediately after takeoff would be extremely difficult due to the very close proximity of the VOR to the runway.
The southeast bound reference is vague. Does TERPS mean southeast bound on the 155 radial or a general southeasterly heading ? However, the 155 radial reference is clear for the “standard” departure criteria (….intercept MSO R- 155…….).
Runway 29: Same as above for runway 29 departure.
NOTE: Also, the field elevation is 3206 MSL. In a normally aspirated piston single, climbing to 5800 will take some time if expected to cross VOR quickly.
In the spirit of learning, please let me know your thoughts.
Regards,
Dan
