IFR checkride coming up...
Hi guys. I've been doing my training, took the written yesterday and
have my checkride in 2 weeks. Couple of questions. 1) The tolerance for MDAs on the test is +100/-0. The natural response to this is of course to target the altitude MDA+50ft, giving 50ft buffer in either direction. My question is this: how do you manage this on the checkride? If the real MDA is 460, so your MDA+50 is 510, do you say "1000 for 460...900 for 460...800 for 460" etc? You can't really say 510 can you, as the D/ E might think you have the wrong MDA. But if I say 460 I tend to go down to 460 - and then it's all too easy to accidentally go down to 459 and that's a bust. Thoughts on how to manage this? For real life it's easy - just raise the MDA 50ft and know you have a 50ft buffer but no more. But for the checkride? 2) Any other checkride gotchas or tips people have for me would be super-useful. By the way I'm talking about a real checkride, not a simulated one. Thanks Tom |

Drop down to the 460 and come up 20.

For real life it's easy - just raise the MDA 50ft and know you have a 50ft buffer but no more. But for the checkride? For the check ride? Do exactly the same thing. I told the examiner that although the MDA/DA is XXX, I'm going to descend to XXX +50 for a buffer, and that if the conditions warranted it, I would creep down closer to XXX (although if I remember correctly, I used 20, not 50). 2) Any other checkride gotchas or tips people have for me would be super-useful. By the way I'm talking about a real checkride, not a simulated one. Thanks Tom Best of luck on the check ride. I hope you post how it goes for you. -- Mark Hansen, PP-ASEL, Instrument Airplane, USUA Ultralight Pilot Cal Aggie Flying Farmers Sacramento, CA |

By the way I'm talking about a real checkride, not a simulated one. I suggest you train and are able to consistently meet ATP standards which are +50/-0. That way on your checkride you will have the confidence to sail through the checkride, not just pass with minimum standards. I'm not a big gadget guy, but sporty's sells various reminder bugs that affix to the altimeter. The suction cup ones are cheap, but I've had them fall off during flight and roll back under the seat. Another cheap method is just to go to an office supply and get a pack of stick on signature pointers which work great. You can easily take them off and reapply as needed and they work equally when targetting an assigned altitude, which is the most frequent deviation when flying IFR after your checkride. |

Just tell the examiner you're flying it a bit higher (within the standards). In real IMC you may choose to fly it 200 feet high if you are ultra sharp on your skills. -robert |

Just tell the examiner you're flying it a bit higher (within the standards). In real IMC you may choose to fly it 200 feet high if you are ultra sharp on your skills. I've always thought adding any sort of buffer to the MDA is a bad idea for novice instrument pilots. Never continue an IFR approach past the MDA, but always be prepared to go to the MDA. Here's why. The typical scenario is a novice instrument pilot adds a buffer to the MDA, say 200' like you said. Then he flies to his imaginary MDA and doesn't break through. So he may try it again, only lower (almost always a bad idea), or he may go to his alternate only to find it worse and then try to go back. All are recipes for disaster. Approaches are designed to be flown to the MDA which provides a reasonable safety margin already. If you don't have the skills to fly to the MDA, pick an easier approach in which you can or don't fly IFR. |

You can descend saying "1900 for 460..." and maybe get to 480 or 490 by the MDA, but DON'T BUST IT! Arriving at the MDA at 660 would raise issues with the examiner, as you're not demonstrating complete control of the airplane. Remember, you're also expected to be centered on lateral guidance, so you should be fine @ MDA. Haven't set the altimeter correctly? You'll still fail!

It's a matter of degree and circumstance. Adding some turbulence protection on a gusty day would be prudent, as would a mention of you doing so on purpose. If you were 200 or more feet high on a decent day, the DE's I know would probably compare it to your other approaches, and possibly let you take another shot at one high approach. Most of them will allow a redo on a mistake, if the mistake is to the safe side. Do it on all of them, and you'll fail. Remember the PTS has standards: Non-precision = +100/-0 @ MDA Precision = 3/4 scale deflection of either needle @ MDA |

The airlines usually round a non-precision (OZ, TWA, AA, SA, and Republic) approach up to the nearest higher 100 feet. This usually results in a sufficient pad in case you overshoot. Probably not a bad technique. -- joeyb Message Origin: TRAVEL.com |
