CPL CPL Instrument Flight Rules and Procedures

Question 1

Under IFR, what is the minimum visibility required for a commercial pilot to commence an instrument approach to a runway with a standard 200-ft decision height (CAT I ILS)?

Accepted Answer

1/2 statute mile

Answer

CAT I ILS approaches require at least 1/2 statute mile (2,400 RVR) visibility for a 200-ft decision height under FAR 91.175.

Question 2

When flying IFR in controlled airspace, what is the minimum fuel reserve required beyond the destination airport under FAR Part 91?

Accepted Answer

45 minutes at normal cruise

Answer

FAR 91.167 requires IFR flight to carry enough fuel to fly to the destination, then to the alternate, and then for 45 minutes at normal cruise speed.

Question 3

What does the term 'decision altitude (DA)' refer to during an instrument approach?

Accepted Answer

The altitude at which the pilot must begin the missed approach if visual reference is not established

Answer

Decision altitude (DA) is the point during a precision approach where the pilot must initiate a missed approach if the required visual references are not in sight.

Question 4

An aircraft is cleared for a standard instrument departure (SID). The SID procedure requires a minimum climb gradient of 300 ft/NM. At a groundspeed of 120 knots, what is the minimum required rate of climb in feet per minute?

Accepted Answer

600 fpm

Answer

Rate of climb (fpm) = gradient (ft/NM) × groundspeed (NM/min); 300 × (120/60) = 300 × 2 = 600 fpm.

Question 5

Under IFR, when is an alternate airport required to be filed in a flight plan?

Accepted Answer

When the forecast at the destination, from 1 hour before to 1 hour after ETA, is less than 2,000-ft ceiling or 3 SM visibility

Answer

FAR 91.169 requires an alternate when the destination forecast within ±1 hour of ETA does not meet the 2,000/3 rule (2,000-ft ceiling and 3 SM visibility).
