These study guide questions were submitted by real pilots who actually interviewed with NetJets
When can you go below DH/MDA? 91.175 You need three things:
1. Aircraft is continuously in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal maneuvers.
2. Flight visibility is not less than the visibility prescribed in the standard instrument approach begin used and:
3. At least one of the following visual references for the intended runway is distinctly visible and identifiable to the pilot: Approach light system, Threshold, Threshold markings, Threshold lights, REIL, VASI, Touchdown zone or markings, Touchdown zone lights, Runway or runway markings, and runway lights.
When do you need a TO alternate? You need a T/O alternate when the airport at which you are departing from is below landing minimums.
When do you need to file an alternate FAR91 and 135? for at least one hour before and after the airport of intended landing, if weather is below(less than)... part 91: 2,000' ceiling or 3 miles visibility; part 135: 1,500' above the lowest circling minimum, if no circling minimums, 1,500' above the lowest published minimums, or 2,000' above airport elevation, whichever is higher or visibility 3 miles or 2 miles more than the lowest visibility minimums, whichever is greater for the instrument procedure to be used.
Know your climb gradient stuff: RISE/RUN Climb gradient is defined by the vertical feet climbed per 1 nautical mile of horizontal distance traveled. Since foot and NM are two different units, and that there are 6076 feet in 1 NM; to find climb gradient %, just covert the NM to 6076 ft, or simply divide the ft/nm by 6076, then times a 100 for %. Take ft per N.M. and divide my 6080 ft expample 600 ft/n.m. would be 600/6080 = 10%
Convert feet per NM to a climb gradient % Climb Gradient % is not affected by ground speed. The correct formula is Rise over Run. 250/6000 = 4.2%. Now you can determine FPM by the following formula. Groundspeed x Feet per NM/60. 120 x 250/60 = 500 Feet per Minute. the first answer has a typo. It should read 550 fpm, not 550 ft/nm, otherwise great info. One of the easiest ways to calculate this is look at the departure chart. On the chart will show you a table with feet per nautical mile required based on airspeed. Look at the 100kt number ex: if it is 550 ft/nm, your answer is 5.5% climb gradient.
How do you figure out the slope of a runway? Rise/Run is correct, but .02% is not. Remember that 1% equals 1/100 or .01. So in the example of 110/5000, the answer is .022 which equals 2.2% not .02%. In other words, just divide the numbers and then move the answers' decimal point to the right two places and that is your percent. .02 and 2% are synonomous (same) It is either 2% or .02, not both.
Rise/Run is the equation. Look at the elevation at each end of the runway. Figure the difference and divide it by the Run (distance of runway): ex:
Elevations: 410-300= 110 ft. difference. Runway length is 5000 ft. 110/5000=.02 % slope.
They may have you brief an approach, so I practiced that a few times because it had been a while since I had done that. A brief is just that. Brief. Start from top left and cover the specifics and any comments. Brief the MAP and taxi procedure once on the ground
When can you descend with out an instrument approach? A visual appr is conducted on an IFR flight plan and authorizes a pilot to proceed visually and clear of clouds to the airport.
1. Pilot must have airport or preceding identified a/c in sight.
2. Appr must be authorized by ATC.
3. Wx must be at least 1000' ceiling and 3 miles vis or greater.
For part 121 and 135 turbojet:
4. Must have 91.155 VFR cloud clearance.
5. Must remain in Class B, C, D, or E airspace and within 35 nm of the airport.
6. Remain at appropriate pattern altitude for either non/large or turbine powered a/c until further descent is required for a safe landing. As long as you can descend below the MEA and maintain VFR to your destination.
What do you do if the vis goes below mins on an ILS outside and inside the FAF? Vis goes below mins outside the FAF-go missed; no turns until reaching MAP
Vis goes below mins inside the FAF-continue.
How would you handle an engine fire inside the FAF on an ILS down to mins? Silence the fire bell and land the airplane, while having the other pilot declare the emergency. Then deal with the fire after we are on the ground. Land the plane then deal with the fire.
