How To Calculate Descent Rate for a Non-precision Approach
Ғылым және технология
How fast should the aircraft's descent rate be between two fixes to arrive at a certain altitude on a non-precision approach? This quick video shows how to determine distance travelled in nautical miles per minute. Knowing the distance travelled per minute and the amount of altitude loss required, the rate of descent in feet per minute can be calculated to arrive a certain fix at a predetermined rate of descent.
This is one example of the many questions asked on the FAA Instrument Knowledge Exam (aka IFR Written Test).
Are you about to start instrument training? I used Gleim for the IFR through ATP and Aircraft Dispatcher written tests and passed on the first try every time. I highly recommend this Instrument Pilot Kit with Test Prep Software by Gleim - amzn.to/3CgFi84
If looking for a stand-alone Instrument Oral Exam guide, this one is highly recommended: amzn.to/3vw6N9O

Determining rate of descent has been a struggle for me so thanks for this video.
so simple and short, thank you!
Thank you !
approach plate says in 3nm,,i did it this way (3100-2400)/3 = 700ft/nm..u are doing 1.5nm/min >>> 700 x 1.5=350ft/min

Ford Tri-motor definitely I think it's the only ford that can fly

Pretty sure it’s a ford Tri-motor

It sure is.
Easier (at practice) is groundspeed/ 2 + 0 ex. 90/2= 45+0= -450vs for 3 degree angle , for 2 is 1/3 of groundspeed. Search for FAA climb/descent table and it works like magic, because obviously nobody will do this math while flying
Was the angle of descent 1.16 degrees ? Lol off topic but yea

No. According to the FAA rate of climb/descent table the angle of descent is around 2.3 degrees.

ohhh ok. I decided to take the velocity vector in the direction of the vertical height (700ft) and then I did 90sin(theta) /700 =350 (distance = speed/time) and then the theta value was close to 1.27 degrees... /@@thecorporatepilotdad

Ohhh nawwww there's alot that's wrong in here lmao. Sorry for the confusion.... I was wondering why the angle comes out to be so small. My approach was incorrect lol sorry
